Diabetes & Cycling
Sleep disorder posting
Once again, I am going through a re-injury occurrence that, in essence, has
ended my competitive cycling career, although I had been winding down anyway.
I am a 50-year old male and have been cycling competitively and doing what I'll
call fast club rides for the last 25 years. I'm 6 foot even and 140 pounds,
so I've always enjoyed climbing, until a few years ago.
Late 2002, during a club ride, I started to have what I thought was a mild
cramp in my right calf, although it somehow felt different from that. I tried
repositioning my foot during that ride as best I could, but nothing changed
the cramp-like feeling. Stupidly, in retrospect, I did about six more two-hour
rides over a few weeks time, but I could feel a dull ache and/or tightness in
my right gastrocnemius almost with every pedal stroke. After even a month or
two of relatively light indoor trainer sessions proved problematic, I finally
stopped and sought medical attention from a sports-oriented group of physicians
(who also cycle). Prescribed anti-inflammatory drugs did nothing noticeable.
Ultimately, I was diagnosed with an inflexible hallux (big toe) that contributed
to tendinosis in my right upper (proximal) gastrocnemius. My understanding of
tendinosis is that it is (or can be) due to an accumulation of micro-tears at
the muscle/tendon junction that has damaged the collagen. It's a slow-healing
area because of limited blood enervation and the protein synthesis process takes
at least three months to remodel the collagen. I started a program of icing,
calf and toe stretching, moderate exercise (walking, Theraband exercises), regular
professional massage therapy and, once cycling, after a 3-month layoff, a gradual
build-up of intensity (a combination of distance and effort) in an attempt to
remodel the injured area to accommodate cycling again to what I had once known.
I also got custom orthotics to address the hallux inflexibility, actually in
At the same time, the podiatrist said the 5 mm shim on my cycling shoes and
8 mm heel lift for my perceived shorter left leg should be discarded, pointing
out I had a functional leg length discrepancy instead of an actual one, contrary
to what I had been told 20 years before. I don't know if this is relevant to
my current problem/injury, but...The old style Time pedals and shoes were good
for accommodating the shim. I now have custom Rocket 7 shoes for my one-size-different
feet and use them with Look Keo pedals, with the orthotics and no shim. My cleats
are fairly far back on the shoes, I should add.
My flexibility throughout my (especially lower) body can best be described as
"bad," even though I have stretched regularly hamstrings, back, etc. for at
least the last 10-15 years. My hamstrings, especially, are tight, even after
exercise and stretching. My bike size and cockpit reach reflect that characteristic
and my on-the-bike aerodynamics are limited somewhat.
Over the last two years, the tendinosis has flared back up from time to time,
due to mild intervals, a difficult/long ride or otherwise building up cycling
conditioning too quickly. It then takes three months or more to resolve, but
it never has resolved completely, I have to say in retrospect. I can get to
a point where I can exert myself cardiovascularly, but I stay away from group
riding where the speeds, efforts and terrain can vary too much. In short, it
has been a competitive cycling career killer. Intervals, sprinting, strong winds
and most any kind of hills have been avoided, and I've paid the re-injury when
Given all that, here are my questions.
1. Any obvious things I am doing wrong or should be doing (or considering)
to prevent re-injury?
2. Are there other specific stretching or exercises you could recommend for
coming back from this kind of injury?
3. Are there any foods or supplements I should consider ingesting that would
aid collagen formation (by obtaining some necessary protein, say) or promote
4. I've never had any problems whatsoever with Achilles' or patellar tendinosis.
This injury site, which is about one or two inches below the back of the crease
of the knee as best as I can palpate, seems very uncommon from what I can tell.
Do you have any insights about frequency in cyclists? Really, cycling has been
my only sport for the last 25 years.
Any insights, discussion or even just commiseration would be appreciated.

Steve Hogg Replies
Your story doesn't sound like a lot of fun. I think the clue to understanding
your situation is that it only occurs on one side and that you have pelvic
asymmetries of function, hence the functionally short leg. In your shoes,
I would be seeing whoever I have to see and doing whatever I have to do to
improve the general structural function of my body as a whole. If you made
Pilates, yoga or whatever, your sport of choice, it would not surprise me
at all if you end up back on the bike injury free, though the time this would
take, I can only guess at.
Re your queries:
1. It is likely that because of your functionally short leg [ you don't specify
which one it is] which is the product of pelvic asymmetries of function, that
you don't sit square on the seat and that both legs function and pedal somewhat
differently with different loads and degrees of extension. You would need
to confirm this before I would attempt to advise further. Mount your bike
on an indoor trainer on a level floor, take your shirt off and warm up to
pedalling in a reasonably hard gear. Have an observer standing behind and
slightly above see whether you sit with one hip dropped OR sit with a hip
that drops and/ or rotates forward on every pedal downstroke on that side.
If so, get back to me with which hip it is and what it is doing and we will
go from there with potential solutions on bike.
2. I don't know. As I suggested above, I think, based on what you have said,
that a global [whole of body] approach to stretching and stabilising would
be the best bet. I say this as it is difficult for me to understand how an
inflexible big toe, [ a problem I also used to suffer from, indirectly caused
by a badly broken ankle and foot] could cause a gastrocs problem such as yours
without a LOT of other factors and short comings. If you improve the way your
whole body functions, you are likely to rid yourself of the underlying cause
of the problem. Don't tackle this on a piecemeal basis, solve the root cause
problem which is an inflexible body functioning asymmetrically.
3. I pass and leave that to the health professionals on the team.
4. As far as my experience takes me, yours is an uncommon injury in a cycling
sense. When I have seen it before, the culprit was always too great a seat
height or a hang to one side pedalling style which caused the other side to
overextend. Too far forward or uncommonly, too far rearward a cleat position
will only exacerbate.
You mention Rocket 7 shoes. I have seen a few pairs over here in Oz and they
looked well made and attractive, but in each case had cleat mounting holes
that in my view were significantly too far forward on the shoe. This may be
part of your problem.
Have a look at this cleat
positioning post, and this
one and see whether that cleat position is achievable with your Rocket
7's. If not, they will modify them, as they have done it for some of the people
I have seen with their shoes.
To conclude, I think it likely that your problem can be resolved or improved
a lot on bike with good cleat position and improved symmetry on bike. Please
get back to me with what your observer finds.
Loss of quadriceps power
This is actually a follow up question from eight months ago when I inquired
about possible causes for overuse of the VMO (July 2004). After experimenting
with setup and following some of Steve's advice the problems appeared to mostly
clear up (though without being able to produce a definitive answer).
One of the possible causes that Steve mentioned was a hip imbalance. The reason
that I bring this up now is that another cycling issue might well be related.
After racing or training 'very' hard for about an hour, my right quad starts
to go numb and lose power. I mentioned this to a training partner who suggested
that I might actually have a hip imbalance. The core muscles fatigue on one
side of the body quicker than the other, leading to the quad having to compensate.
He suggested visiting a physio for manipulation/follow up. (His advice coming
from personal experience) The problem is that my non-cyclist physio couldn't
find any problems. He suggested that I work on core strength and flexibility.
The reason that I asking this follow up question is that I've noticed that
my right VMO is also still the first major muscle to fatigue. I only made the
possible linkage between the two recently (not being the sharpest tool!).
So my basic question follows: are the loss of power in the right quad, and
the fatiguing of the right VMO possibly related? (possiblly, as suggested, because
of a hip imbalance).
And if so, what should I go back to the physio with, or alternatively, alter
with bike set up? Hope you can help!
Steve Hogg Replies
The VMO is the major lateral muscular stabiliser of the knee. If it is fatiguing
more quickly, it is likely that there is a challenge to stability on that
side and the VMO is working hard in an attempt to stabilise. As to the connection
between that and the rest of the right quad going numb, I can only guess at.
You mention that your physio could find nothing wrong. Did they look at the
site of the problem or did they do a whole of body structural assessment.
If they did not do that, find a knowledgeable one who can and will. Even better
if they are a cyclist.
Brisbane is a big enough city to have physios who are also cyclists. Contact
their professional organisation and find out who they are. I think it extremely
likely that you have a hip imbalance but this has to be confirmed or otherwise.
I would like to give you a definitive answer to your last question, but I
will leave that to the health professionals. With all respect however, why
are you trying to educate your physio? Find one who knows their stuff instead.
As to altering your position - get back to me with what hip you are dropping
on the bike. Even then, I can probably advise on improving the situation but
it would be far better if the underlying problem was resolved.
Calves and the pedal stroke
I got to arguing with a mate about which muscles get used when during the pedal
stroke, and was hoping you could share the true "science" of it (there's a whole
$10 riding on this)
The main question was about when the calves get worked. Road warriors have
these amazingly defined gastrocs, but its hard to pick a loaded calf raise in
the stroke. Is it in the pull up with the back leg (I think that's hamstring)?
Is it just high reps that gives the definition, or is there some other point
in the stroke that works them - downstroke with pointed foot?
Since I've got you started on the topic, I'd love it if you could outline the
kinesiology of the whole pedal stroke
Scott Saifer Replies
Gastoc is active during the down-stroke and first half of the upstroke (30-270
degrees). If calf muscles were not active, the heel would drop until the limit
of movement of the joint was reached on every stroke. Since you asked about
the whole pedal stroke, I'm attaching an abstract of an article that examined
it. Sorry for the typos.
Jorge, M and M. Hull (1986) Analysis of EMG measurements during bicycle pedalling.
Journal of Biomechanics. 19(9): 683-694
Purpose: The authors defined four objectives: To determine the regions
in he pedal stroke in which eight leg muscles are active, to note the effect
of hard vs. soft soled shoes on these activities, to relate these activities
to power output at constant cadence, and to test the effects of seat height.
Subjects: Subjects were six experienced cyclists (1 recreational,
one tourist, 2 former racers and two racers).
Methods: Subjects rode a bicycle of the same size as their own bicycles
on rollers. EMG activity during pedaling was measured in the gluteus maximus,
rectus femoris, vastus medialis, vastus lateralis, tibialis anterior, gastrocnemius,
biceps femoris and semimembranosus of the right leg. EMG was processed to
show regons of activity and inactivity and also intensity of activity divided
into 36 degree segments of crank rotation. EMG was normalized for each muscle
for each subject by dividing by the maximum value found for that subject in
that muscle and then averaged over all the subjects. Crank angle and cadence
were also collected. Data were gathered over two pedal revolutions and averaged.
A four channel EMG recorder was used so data had to be gathered from four
muscles at one time in two data gathering sessions for each subject and condition.
All tests were carried out at 80 rpm. A total of five conditions were tested
with one variable changing per condition. The base condition to which other
were compared involved pedaling at 100 W in cleated shoes at a seat height
of 100% of trochanter height. The varied conditions were: soft soled shoes,
lower power (83 W), higher power (125 W) and lower saddle (95% of trochanter
Results: Pretrial testing indicated that EMG data were highly repeatable
from cycle to cycle and from test to test. Activity patterns were fairly similar
though not identical between subjects. During the reference condition, on
average, rectus femoris was active from 280 deg to 120 deg with peak activity
(>50% max) from 300 to 70 deg. Vastus lateralis and vastus medialis came on
around 310 deg but shut down at the same time as RF Peak activity was from
340 to to about 100 deg. Gluteus maximus and hamstrings came on at TDC but
while GM shut down at 130 degrees (peak 10 and 110), hamstrings remained active
until 20 degrees. Biceps femoris was most active from 80 and BDC. Semibembranosus
was most acive from 60 to 240 deg. Tibialis anterior was active from 280 deg
to just after TDC with peak activity from 300 deg to TDC. Gastrocnemius activity
is complementary and non-overlapping to that of TA and runs from 30 to 270
deg. While quadriceps and hamstrings were coactive for 110 degrees of the
cycle, areas ofpeak activity did not overlap. These patterns were independent
of pedaling conditions. Activity levels on the other hand were influenced
by pedaling conditions. Soft soled shoes were associated with 53% increase
in vastus medialis activity in its region of peak activity. A similar increase
of 67% was found in vastus lateralis while the hamstrings increased activity
by more than 120% at times of peak activity. Gastrocnemius and rectus femoris
showed slight decreases in peak activity. All hip extensors shoed increased
activity with increased power, but interestingly hamstrings also showed increased
activity at lower and higher power, though by a greater percentage at higher
power than at lower. Quadriceps msucles were equally active at referecne and
lower powers, but became 70% (rectus femoris and vastus lateralis) and 14%
(vastus medialis) more active. GAstrocnemius was less active at lower power
compared to refernce but did not continue to increase with the switch to higher
power. Tibialis anterior activity increased more with increased than with
decreased power. Gluteus maximus activity was unchanged by loering the saddle
but qudriceps and hamstring activity increased by the same amounts as in the
Conclusions: Because cocontraction is minimal modeling of joint moments
and muscle actions are interconvertible. Care must be taken when comparing
different studies to ascertain saddle heights and shoe types.
My wife is a recreational cyclist who is experiencing a sudden onset of one
sided foot pain located midline and behind the ball. She describes the pain
as being primarily on two pressure points. She first noticed this pain after
switching to a new shoe/pedal combination 3 weeks ago (Sidi Genius 5/ SPD-SL).
The cleat was positioned behind the ball using the formula Steve Hogg mentioned
in a previous post. Her old shoe/pedal setup was an inexpensive mountain shoe
with SPD pedals. Is this normal shoe break-in pain or is there something we
Kelby Bethards Replies
It is possible that the pain is related to her foot adjusting to a shoe with
a different last - more arch support, less arch support, longer arch, etc.
Shoes are made on a "standard" last, but our feet are not.
I don't know if this is of interest to you but I use in my shoes and know
quite a few cyclists that use the over the counter type orthotics...SuperFeet
($30-40/pair) is one brand (nope, I don't own stock).and there are a few others
similar out there that help put the foot into a "neutral" position. Now, my
feet even hurt when I started with these, because the support on my foot was
different, but now I don't ride without them.
Broken collar bone
I recently broke my left clavicle in a biking accident. About how long does
it take before I could be back out on the open road? How long does it take to
completely heal? And why is it a bone that just heals without being set or pinned?
Kelby Bethards Replies
This is a "on an individual basis" sort of answer, but without looking at
your films, etc its hard to be precise. Typically a fractured clavicle takes
about six weeks to heal...I know one of the sports med orthopedists that does
pin clavicles on pro cyclists etc, so they can be back on their bike quickly,
on the indoor trainers etc, in a matter of days. They are difficult to pin
and heal just as well on their own, depending on the location and severity
of the fracture.
The bones make what is called a callus around the fracture and remodel and
lay down new connective tissue/bone to sort of tack the two (or more) pieces
back together...as time goes this hardens and becomes the "new bone". It is
not a "load bearing" bone so it does generally heal well without intervention.
If you have a regular doc, I'd go see him/her with your films and ask about
getting on the bike...start with the indoor trainer if you have one and the
make your way out to the road. As you may have learned, it does not take much
force to fracture a collar bone so I wouldn't want you to break it again too
soon. I have seen cyclists get out in as little as three to four weeks and
have seen it take 8 weeks...but you and your doc will need to decide on when
you should get out and how much risk you want to take.
You may recall I emailed you last month regarding calve issues.
I'm making some progress, but I have one quick question. Are there any pain
symptoms of a cleat that is position too far back? (otherwise stated as the
ball of the foot too far forward over the pedal axis) Or is this a case where
there is no pain that develops but instead a breakdown of the pedaling dynamics/efficiency.
I want to know what the signs are of going too far in that direction. Thanks.
Steve Hogg Replies
I do remember your query to CN. If the cleat is too far back, ankle movement
becomes too limited and there is a loss of smoothness at the bottom of the
stroke. A lack of what I call ' flow' as I don't know what else to call it.
The pedal stroke becomes jerky and it is hard to pedal at high rpm.
While I have seen the occasional injury caused by too rearward a cleat position,
it is not common and is usually associated with too high a seat height for
that cleat position. If you stick to the recommendations I gave you for cleat
position plus or minus a mm or so, you will be safe and are unlikely to have
problems resulting from cleat position.
Don't forget to stretch those calves though!
TT training and lactate threshold
Today TT training was discussed and recommended intervals were given. The question:
if one continues to train threshold levels will your lactate threshold continue
to increase or will you just reach your genetic ceiling and plateau? Typically
this is the time to start a different block working on a different system. Have
I got all this wrong? Thanks.
Ric Stern Replies
Great question! The upper limit of aerobic endurance ability is set by the
maximal oxygen uptake (VO2 max) that your body can use in a specific exercise
modality (VO2max maybe different in different sports for the same person)
- in other words VO2max is the rate limiting mechanism in endurance exercise.
It is known, that in trained, well-trained, and elite athletes that the upper
limit of maximal sustainable work for ~1-hour is ~ 90 % of VO2max. This effort
would be significantly higher than the term "lactate threshold" which scientifically,
is often described as the work rate (ie; power output in cycling [watts -
W], velocity in running [m/s or km/hr]) that elicits a 1 mmol/L increase in
lactate over exercise baseline levels (i.e., ~ 2.x mmol/L) or the work rate
that elicits a fixed ratio of 2.5 mmol/L. These definitions of LT would be
~ 10 - 15% less than the effort that could maximally be maintained for ~1-hr.
Not all athletes would be able to able to race at this 90% of VO2max, and
indeed with the intervals I suggested in the previous edition of Fitness Q&A
one of the adaptations that would likely occur with such a prescription is
that the per cent of which you can operate would increase at a greater magnitude
than would your VO2max - in other words the sustainable % would get closer
If you can already exercise at this ~ 90% then the only way to really improve
your TTing ability would be to increase your VO2max, this could be achieved
by shorter more intense intervals (~ 3-8 minutes at an effort that just elicits
VO2max). I previously described such intervals back here http://www.cyclingnews.com/fitness/trainingstern.shtml.
Any efforts of sufficient duration at zones 5 and 6 will help increase VO2max
(and maximal aerobic power - MAP) - see
this useful posting for training zones.
However, if your VO2max is very small (relative to body mass) then you will
also need to think about raising your ceiling, which can be done with the
above suggested intervals.
Ultimately, it's unlikely that many will reach a true limit to their abilities
- you're possibly more likely to be constrained by other things (e.g., lack
of training time). With the correct training you're likely to continue improving.
Hope that helps…
Low HR Max
My resting heart rate is typically 45 bpm. I am a 32-year-old road cyclist.
I am 5'11" and weigh 160 lbs. I average 80-100 miles per week at fairly high
exertion levels. I have been using a heart rate monitor consistently for about
eight months now. I've noticed that my maximum heart rate at full effort seems
to be approximately 175 bpm. Try as I might, I cannot get my heart rate up to
180bpm. Am I correct in thinking that this is a somewhat low maximum rate for
someone my age? If so, what condition(s) could be contributing to the low rate?
Could incorrect training be a factor?
Ric Stern Replies
I'm not sure why you need to get your HR to 180b/min or how you arrived at
this figure? Often, in general fitness articles, writers will often suggest
that HRmax is defined as "220 minus age" - which in your case would be 188
b/min. However, this figure has quite a large standard deviation associated
with it (if memory serves me correctly it's ± 12 b/min, which makes it no
good for predicting an individuals HRMax).
As regards your HRmax being ~175 b/min, your upper limit is what it is, and
the number is not a measure of performance (i.e., just because someone else's
HRmax may be higher than yours doesn't necessarily make them fitter than you).
In fact, it's likely that HRmax will *decrease* with regular, quality endurance
However, to reach HRmax, it is somewhat difficult, you need to be well motivated,
and the effort often needs to be gradually increased (such as in an incremental
test). You don't want to 'sprint' as hard as possible to get there (as you'll
fatigue way before your HR has a chance to increase to max). The test we use
at RST to ascertain maximal aerobic power (MAP) can also be used to ascertain
HRmax, see this posting. It should be
noted that intense, maximal testing such as this is not recommended for everyone,
as it is a severe and stressful test.
Uric acid excess
I'm 32 years old, riding purely recreationally, and until a recent snowboarding
injury I was putting in an average of 350 km per week over 5 rides. I've pretty
much recovered from the snowboarding injury , which was to both knees and appears
to have been correctly diagnosed as medial ligament strain. Just as I was beginning
to start training again I started experiencing pain in my knees which felt totally
different to my previous injury.
I stopped training and while I was off the bike and carrying on with only my
upper body weight programme my knees progressively got worse as did my left
ankle. I'd wake up in the mornings with my knees and ankle aching having gone
to bed with little or no pain. This would continue throughout the day with no
discernable pattern linked to anything I had done as far as I could tell.
I was talking with my physio / sports masseur about this and he asked had I
been drinking coffee, which I had; well over my normal amount, and I'd also
been having a couple of glasses of wine in the evenings while unable to train.
Anyway, he suggested stopping the coffee and the wine and taking cider vinegar
three times daily to flush my system of excess uric acid which might be causing
joint inflammation. I've done as he asked and in 4 days there has been a noticeable
improvement in my pain. My question is have any of the panel come across this
and if so what are your thoughts and advice. Thanks.

Based on the circumstantial evidence that you've provided, I would blame
your pain on gouty arthritis. Gout is most common in middle-aged men. It is
characterized by acute attacks of inflammation, swelling, and intense pain
and periods of remission. Before an individual knows that they have gout,
their symptoms may be diagnosed as a sprain or tendinitis. The joint pain
and inflammation associated with gout results when crystals of sodium and
uric acid form in and around the joints, tendons, and cartilage of bones.
Over time, the uric acid crystals increase in size to form gritty nodules
called "tophi". Uric acid in the urine precipitates with calcium, forming
kidney stones. Abnormally high levels of uric acid in the blood (hyperuricemia)
cause gout. Uric acid is produced in the body from metabolism of purines,
chemicals present in DNA and RNA. Foods that are high in purines will produce
large amounts of uric acid when they are metabolized. Unfortunately, some
people are genetically-predisposed to having hyperuricemia. For these individuals,
limiting their dietary intake of foods that are high in purines (red meat,
seafood, organ meats, yeast) may help reduce their symptoms. Beer also contains
significant amounts of purines.
In general, alcoholic beverages also should be avoided because they interfere
with the body's ability to excrete uric acid. Other drugs, like caffeine,
aspirin and diuretics, which promote water excretion by the kidneys increase
the formation of uric acid crystals by making the urine more concentrated.
Given your symptoms and the improvement you experienced when you reduced your
intake of caffeine and alcohol, it is plausible that you have hyperuricemia
and gout. However, high blood levels of uric acid can only be determined by
a blood test.
Hyperuricemia does not necessarily mean that you have gout. Many people have
elevated uric acid levels, but don't know it because they are asymptomatic.
Gout can only be diagnosed by observing uric acid crystals in a joint using
an X-ray. It would be a good idea for you to have these tests so that, if
you have gout, drug treatment can begin as soon as possible. Gout is a progressive
condition and the attacks are certain to occur more frequently if the disease
goes untreated. During the acute phase, non-steroidal anti-inflammatories
(with the exception of aspirin), corticosteroids, and cochicine are used to
treat the inflammation and pain. After the attack has subsided, drugs are
given to reduce the concentration of uric acid in the blood.
Uricosuric agents work by increasing uric acid excretion by the kidneys.
Allopurinol is a drug that blocks production of uric acid by inhibiting the
xanthine oxidase enzyme. You might be wondering if you couldn't just stick
with the old-fashioned apple cider vinegar treatment and forget the stronger,
prescription drugs. The idea behind the apple cider vinegar is that it will
alter the acidity of the blood so that the uric acid will stay in solution
rather than crystallizing in your joints. Apple cider vinegar is made from
fermented apples. In the first step, yeast convert the carbohydrate in the
apples into alcohol. In a second fermentation, bacteria metabolize the alcohol
to acetic acid-the compound that makes vinegar bitter and acidic.
Apple cider vinegar has very little nutritive value; it provides small amounts
of carbohydrate, calcium, magnesium, iron, and potassium. The pH of apple
cider vinegar is about 3, which is less acidic than the pH of the stomach.
It is unlikely that consuming apple cider vinegar in small amounts is going
to have a significant effect on the acidity of the urine. There is no evidence,
other than anecdotal reports, that apple cider vinegar reduces uric acid concentration
in the blood or urine or that it helps prevent gout attacks.
While the effects of the acetic acid on your gout symptoms are questionable,
it is known that the cider vinegar will dissolve the enamel of your teeth.
So if you are going to continue with your cider treatment, be sure to rinse
your mouth with plain water after drinking the cider. If you are interested
in trying a food-based treatment, you might consider adding fresh cherries
to your diet. Regular consumption of cherries normalized blood uric acid levels
and reduced gout attacks in a clinical study of gout patients. Another study
reported that cherries reduced the concentration of uric acid in blood and
in urine and reduced markers of inflammation.
Cherries have large amounts of antioxidants, including a class of compounds
called polyphenols. The polyphenols, especially anthocyanin, prevent inflammation
by inhibiting cyclooxygenase, a key enzyme in the lammatory pathway. Non-steroidal
inflammatory drugs also work by inhibiting cyclooxygenase. Good luck.
With all the talk about blood transfusions (homologous and otherwise) I assume
that there must be a real performance advantage to the practice, at least for
world-class athletes. My question is about the opposite case - donating blood.
I regularly donate to the local blood band, and they always warn me not to exercise
strenuously for 24 hours. I always assumed this had to do with fluid levels.
Well, I gave my usual pint on Tuesday this week, and Sunday I tried my favorite
climb. My time was 2 1/2 minutes (10%) slower than the last time I timed myself
on the same course. Conditions were pretty much the same, and my perceived effort
was the same. Could losing a pint 5 days earlier affect performance this dramatically?
By the way, your answer won't change my donating habits, but it might give me
another good excuse for being so slow.

The quick answer to your question is yes, donating blood does affect your
performance for a while. While you may be able to get your total circulating
volume back up in a day or so, you are still lacking in red blood cells, the
oxygen carriers. The bone marrow responds to chemical signals sent from your
kidneys telling it to produce more red blood cells when you are "low" (like
after a transfusion or bleeding and so on). However, this process doesn't
take place as quickly as restoring circulating volume (red blood cells, white
blood cells, platelets, plasma, etc).
So, the converse is true, having a few extra red blood cells can boost ones
performance, but this can also be dangerous, having "too many" red blood cells.

Yes, donating blood will make you slower during hard efforts until your body
replaces the fluid and red cells that you donated. Your being 10% slower the
week after donating is within the range of loss of speed I would expect. Maybe
one of the other panelists knows something detailed about how long it takes
to replace the donated red cells. You've got your excuse, and thanks for doing
your bit by donating blood.
Hi, I am a 57 year old male in excellent shape, at least until about two weeks
ago. I am an endurance and serious recreational rider. I am 6 feet tall and
weigh 200 lbs. I have been riding for years. Two weeks ago I commuted to work
which I do 95% of the time and on the way home decided to use this time for
a training ride. I was just turning into my ally after about 35 miles of a great
ride when I hit a small patch of sand and went down on my left hip, which I
After two pins and too much laying around I am getting better, slowly and painfully.
My question is; what can I do so my left leg will not atrophy too much during
this time? I am on crutches with no load bearing on the right leg, only toe
balance. The other thing is that the longer I am off the bike the more afraid
I am to think about doing it again. I want to ride more than anything but I
fight the psychological fear of falling again. Thanks.

Depending on where the fracture is, the difficulty of the surgery and other
variables, you may have to wait a bit before riding, if you are currently
only touch wt bearing. I went through the same thing after a knee surgery
and had to wait a while to ride again (about 3-4 weeks, if I remember right).
SO, what you need to do is, ask your orthopedic surgeon or your physical
therapist when you can get on the bike trainer or exercise bike again...they
should be able to give you an idea.
Hello, I am a 44-year-old cat 2 racer. I usually do about 200-250 miles a week
and also have a full time job. In The last few weeks I have been getting run
down and have a constant exhaustion problem. What supplements should I be taking
to help keep me going? Thanks.
Scott Saifer Replies
May I suggest vitamins R and S. R is relaxation and S is sleep. Unless your
diet is actually deficient in some nutrient, the best cure for fatigue is
rest. If you are getting less than 8 hours of sleep per night, increasing
sleep will probably help with the exhaustion. Also examine the balance of
intensity and base mileage. Especially in the full-time employed, it is difficult
to recovery and maintain energy levels is you are doing harder efforts (say
above 80% of maximum heart rate) for more than a few minutes more than twice
One area of diet that might actually have an influence is carbohydrate and
total calorie intake. If you are, or have been, losing weight recently, start
eating more until your weight stabilizes.
I'd suggest riding only recovery pace for several days, sleeping at least
8 hours per night and eating enough to maintain weight. If you do that for
a week and the exhaustion does not clear up, call your doctor.
Leg length discrepancy - can't dial it in
Let me tell you what I know about my body and position, and then I'll tell
you where my pain is and see if you can offer any setup advice. This also includes
what I've changed in the last two months. I'm a Cat 4 racer and have done 2000
miles since January 20.
First off, my right leg is shorter than my left. I have not had an X-Ray done
to measure the exact length, but one licensed therapist measured it at an inch.
The doctor to whom she recommended me measured it as "at least" 3/8ths of an
inch. Because of back pain he sent me for an MRI (awaiting result) to check
my discs and sent me for a 3/8ths inch insole for my work shoes and everyday
shoes. The physio also said my right deep hip flexor was quite tight, that my
right hamstring was tighter than my left, and that my pelvis was twisted (right
up, left down I believe). I used to play running sports (soccer, lacrosse) and
never noticed any issues with movement. I am actually fairly flexible compared
to my teammates, but I know that might not mean much.
On long rides my whole lumbar region, especially the left side, would get progressively
more uncomfortable and sore and painful. I also noticed that my right knee always
lined up in front of my left, and, lastly, that my pelvis was crooked on the
saddle. This was noticeable by feel as well as by the Selle San Marco branding
on my shorts which sat to the right side (looking from the back... I thought
it would be the opposite) and more forward on the right as well. My inner thigh
on the right would rub the nose of my saddle as well. My left leg seemed stronger
and more evenly developed in the quads and the hamstrings. I also began to notice
that my right IT band was quite tender after long rides. The physio saw me after
I noticed all this body stuff, actually.
Once I saw the doc, who prescribed the lift, I went to the LBS and got two
of the sidi plates (two year old genius model) and added those to the sole of
the shoe between the cleat and the sole (on top of another plate, actually).
I use the Shimano Ultegra "Lance" pedals. I have the cleat as far back as it
will go, which barely gets the ball of my foot ahead of the spindle. Anyway,
I put these on, and I immediately noticed a feeling of more strength and balance
on the bike. I would say the two plates measured 3/8ths of an inch total. I
have a powertap, and I noticed an increase in power, which could have been due
to training. My IT band felt better after rides, and I raised my saddle a few
mms, until I felt comfortable, basically. I rode a good number of miles over
the course of three weeks with the new plates, and I would say I felt less crooked
and more powerful. I had to adjust my right cleat as well, pointing my toes
slightly more outward than before. Knees good, ankles good, IT band better,
I began to sense that my body had loosened up a little. I had also been using
the lift for a month and had been stretching my quads, hammies, and especially
my right hip flexor (psoas?) after every ride. Oddly enough, I began to feel
a bit crooked on the bike again. No new pain, just not quite straight. Maybe
I became more sensitive to less of a difference. So I added another plate. This
raises the difference to about half an inch. I raised the saddle again, but
not too much. Knees feel good. Two weeks later, and I still feel ok, but something's
not quite lined up. I still sit with my right sit bone farther forward, and
yesterday during my first long RR of the season (60 mi), my left lower back
became quite tight and painful again. It was cold and raining, but it was worse
than I have experienced in a while, though I've been riding 60 miles and more
on the weekends for months now.
Also, I've noticed that my left cleat seems to move around in the pedal fore
and aft more than the right. In fact, it makes a clicking noise during pedal
strokes as the cleat hits the front or back of the pedal. The right has never
done this. The noise is not new. My pelvis now feels a little straighter, and
I never rub my right thigh on the nose of the saddle, which is now straight;
however, my right knee tracks to the outside, which is new I think. I'm just
trying to figure myself out as best as possible. I suspect that some of my LLD
is in the femur and some is in the tibia.
One last variable: I separated my left shoulder in high school, and my clavicle
on that side sits slightly higher as the tendon was stretched permanently when
injured. This makes it hard to tell if my left arm is also longer than my right,
or if my shoulders are just off kilter. On the whole, I have good core strength
and have a fairly balanced musculature in my upper body. I ride a bike that's
a bit long for me in the top tube and run 170 mm cranks. My new ride should
arrive shortly. My coach/the fitting guy (he is one and the same) at the local
shop has put me on a smaller frame (a CAAD 8 52cm) with the FSA big setback
post (to make up for the steep seat tube - he says I have longer femurs which
affect my balance and explains my desire to scoot farther back than I can on
other posts and my current ride) and 175 mm crankarms. My current setup on my
1994 Schwinn Super Sport is a little too "agressive" for the hoods and drops,
I think, but needs to be that way (short stem already) in order to put my butt
back enough. I'm not sure what other information I could give you, but I would
really appreciate any advice you have for the LLD, the back pain, etc. as well
as comments on what I've done with the three plates as shims and the new setup
on the bike.
I hope reading the long question and info hasn't knackered you too much. I'm
tired just from writing it! Again, your comments and advice would be much appreciated.
I do try to take a dynamic approach to my position, as you advise, and I think
it's been very helpful.
Steve Hogg Replies
Yeah, you have posed a long question; but I wish there were more people with
your body awareness and sensible approach to solving their own problems. Because
you have posed a lengthy one it is easier to break this response down to point
1. The only information I will believe about leg length discrepancies is
an X-ray or scan in a standing position with distances measured from joint
centres. Any other diagnostic technique is a guess, sometimes a fair approximation
and sometimes not even close, because of other complicating factors. Don't
get hung up on any particular number. Even if you know accurately what the
discrepancy between long and short legs is, what really matters is what the
implications are on the bike .Given the plethora and variety of compensatory
measures different people can evolve autonomically to accommodate similar
measurable discrepancies, any packer used under a cleat may need to be anywhere
from significantly less to occasionally more, than the measurable leg length
2. Adding Sidi adaptor plates works as you have found, but it would be better
if you could position your cleats further rearward. You have no doubt seen
the various cleat posts so I will leave it at that. If you can find the budget
to change to DMT shoes, they have cleat mounting hardware that is further
back relative to foot in shoe than any other brand out there.
There are two traps with using the 3 x Sidi packers. Firstly they are each
a touch over 3mm thick through the middle of the adaptor but only 2.5mm thick
at the front and a tiny bit over 2mm thick at the rear. When you stack them
as you have, you then have a more pronounced curve to where you bolt the cleat
than if only using one adaptor. Sometimes this makes entry and exit from the
pedal hard as the cleat has to bend more than it's designers intended to mould
to the [increased] curve of the sole of the shoe. The solution for this is
to fit a 2mm thick washer between any two of the adaptors underneath the rearmost
hole through which the adaptors are bolted to the shoe. This will reduce the
amount of curve and allow greater ease of pedal entry and exit. Secondly,
when packing a shoe up as you have quite sensibly done, you are increasing
the distance from the sole of your foot to the pedal axle. This is unavoidable
but has two potential consequences. If you are of pronounced or moderate heel
dropping technique, at point of greatest heel drop you will have rotated the
ball of your foot further behind the pedal axle than on the non packed foot.
This can, if you are susceptible, lead to an increase in calf strains or achilles
tendon problems. If not particularly susceptible to those problems it will
lessen stability of the foot over the pedal because of increased rocking torque,
which is a fancy way of saying that the packed up foot requires more effort
to when it comes to stabilising the foot fore and aft over the pedal.
The solution to minimising this effect is to move the cleat back about 1mm
further back relative to foot in shoe than the other foot for every 5mm of
packer that you have to use. Another factor when packing up a foot is that
you are reducing foot speed [not pedal speed] through the bottom of the stroke
because of the reduced effective lever length at bottom dead centre. This
is a compromise, but if someone has a difference is leg length, they are likely
to benefit simply because the theoretical disadvantage is less so than the
alternative, which is to either reach too far with the short leg or under
reach with the long leg.
3. You say that you are still sitting with your right ischium [ sit bone]
further forward than the left one. This is the likely source of your left
side lumbar pain. I suspect based on experience and what you have told me,
that it is likely that under sustained pressure like that you experienced
in your road race, that you are twisting further forward on the right to reach
the pedal with power and control and the left spinal erector is bearing the
load. This is even more likely if you are right handed. You may not yet have
packed up your right cleat enough, OR perhaps you have, but the combination
of packer and too far forward cleat position is challenging your ability to
control well, the pedal stroke on your right side. Try twisting your seat
nose slightly to the right to more or less square your hips and sit bones
up. This will mean that the right leg will have to reach even further which
may necessitate more packing. If you do this and it feels better under low
to moderate loads, buy a set of DMTs [assuming they fit well] and get your
cleats where they need to be rather than where they are now. If, as I suspect
you are still dropping your right hip under load, the left leg will have to
move laterally to accommodate that to some degree. This may be the root cause
of your loose feeling and click between left shoe and pedal.
4. Another thought that occurs to me is that you have described raising the
seat every time you fitted additional packing under the right cleat. This
is fine if you were sitting too low to accommodate a short leg. But if not,
and a lot of the right side issues you have described suggest the right leg
may have been over extending, you are solving a problem one way and perhaps
adding to it with seat height. The most effective seat height is the one where
you can perform for sustained periods comfortably and without risk of injury.
5. Lastly, a lot of what I have said is not definitive, I am playing the odds
of likely occurrences. If any of this strikes a chord, terrific but it maybe
I am off beam in some things. Don't give up in your search for increased injury
free performance. Making one change at a time the way you have is the way
to go. As the process continues and your body adapts to each positive change,
you will find more and more refinement is necessary. This is normal and not
to be thought of as a problem.
Diabetes & Cycling
In regards to the questions submitted by Lance Sanderson, I can provide some
personal experiences. I have been a Type 1 diabetic for 5.5 years, using multiple
kinds of insulin (including Novolin N, Novolog, and Lantus), and now a Medtronic
insulin pump. I understand the fear of blacking out due to hypoglycemia, I still
can sense when this is happening, but I know many diabetics who cannot. I also
ride 100-200 miles per week, and have never passed out while cycling, or during
any other form of workout. If you want precise control over blood glucose levels
and insulin delivery, I highly recommend an insulin pump. Dosing is more convenient
and precise than with needles, and the control that you have is enormous. The
insulin pump uses short-acting insulin (Novolog, in my case), that is delivered
at what is called a basal rate.
You can have multiple basal rates for different times of the day, as well as
the ability to set temporary basal rates for up to 4 hours. When you eat, you
enter your blood glucose level and amount of carbohydrate being eaten, and the
pump provides you with a bolus of insulin (measured to the tenth of a unit)
to cover that meal.
The feature that I have found critical for maintaining my cycling is the temporary
basal rate. A few minutes before I leave to ride, I set the basal rate to 50%
for the length of my ride. If my basal rate was 1.1 u/hr, then the pump will
only deliver .55 u/hr while I am riding. This prevents the sudden hypoglycemia
that can occur when you combine exercise and insulin. I always ride with extra
food, especially gels, as they are an easy way to recover from an episode of
hypoglycemia. The key disadvantage of Lantus in this situation is that it provides
the same level of activity for 24 hours, whether or not you need it. While exercising,
you just don't need as much insulin. Another product that may help is using
a heart rate monitor with calorimeter, like a Polar. The calorimeter isn't very
accurate, but as long as it is consistent, it will help you figure out how much
you need to eat to maintain normal blood glucose levels while riding.
Finally, learn just how much insulin or carbohydrate your body needs for each
ride based upon time (not mileage), effort, and weather conditions. You can
avoid hypoglycemia by eating just the right amount as you go along, while still
getting the benefits of exercising. Keep the rubber side down, and don't hesitate
to send me an email if you have more questions.
Sleep disorder posting
Hi guys, I just read this
The response by Kelby didn't state this, but to me it looks like the guy may
have insomnia caused by overtraining.. It is a well-known symptom. A few years
ago I was living in France and did 5 months of training in advance of the season.
While the workload on any specific week didn't seem huge, the fact that I was
training alone and that each of my spins was probably run off at a pace 10 bpm
too high for endurance training meant that I got quite run down. One of the
symptoms of this was waking up at 4 am each morning and being totally incapable
of getting back to sleep. Sounds like Paul is having this problem. His carb
intake may be helping him to deal with the overtraining and thus helping him
a little but I'd hazard a guess that it is the miles/efforts he is doing which
could well be causing the problem. All the best.
