Leg length discrepancy

Maximum heart rate
Unrelenting back pain
I am 50 year old avid recreation cyclist riding about 100 to 150 miles per
week on rolling terrain. I average about 10 to 20 miles per hour. I am 5'11
at 160 lbs. I ride a 56 CM Cervelo RS stacked at 25 mm and a 110 mm stem.
I began to experience persistent right sided lower back pain in 2004. I had
injured my right lower back the previous fall by hurling some cast iron pipes
and suffered some ensuing back spasm shortly after. The pain usually starts
about one hour into riding, at times preceded by intense heat like sensation
in the offending location which is at L4/5 and the level of iliac crest centered
at the lateral edge of the right para-spinus muscle.
When severe, I can pinpoint it to the para-spinus tendon. The pain is quickly
relieved by stretching and extension and only to return shortly after riding
resumes. Higher riding intensity brings on the pain sooner. I suffer no other
neurological symptoms or pain radiation to my thigh.
I have had multiple bike fittings with gradual raising of the stack height
hence the RS.
After several years of suffering, I elicited the service of various professionals,
each with different opinion. MRI was ordinary for a man of my age with the typical
mild degenerative changes and slight disk bulging and no major findings.
Despite rigorous core training and stretching regimen, the pain continues
to worsen. It is now chronic, the right paraspinus now bulges asymmetrically
when compare to the left, it is palpably tense and my therapist repeatedly noted
that my left leg is visibly shorter by up to one inch. The leg discrepancy seems
to correlate with the degree of pain I have for that particular week.
My questions are:
1. What are the potential causes for this ailment?
2. Is my right and the symptomatic side or is the left that is causing contra-lateral
or compensatory reaction on the right?
Let the truth be told, if it takes a trip to Down Under to solve this, I will
gladly book a flight on Quanta's.
Jerry Yuan
Atlanta, GA
Steve Hogg replies:
To answer your questions;
1. What are the potential causes for this ailment?
You are dropping and / or rotating one hip forward on each pedal stroke on
that side. As to root causes that set you up for this - who knows. Accidents
of birth, development or misadventure and the compensatory patterns evolved
to cope with all of any of those.
2. Is my right and the symptomatic side or is the left that is causing contra-lateral
or compensatory reaction on the right?
It could be either. A hypertrophy of the paraspinus muscleson one side is
always the result of an asymmetric loading over time. It can be on the hip
dropping side or the non hip dropping side. I've seen plenty of both.
What to do?
Before you consider getting on a plane, here is a "To Do' list.
1. Get hold of a copy of "Stability, Sport and Performance Movement" by Joanne
Elphinston. Brilliantly accessible book on a complex subject. Daily I see
people who can often demonstrate superior core strength in static positions
but lose it totally once they get on a bike and start applying force to the
pedals. There are many potential reasons and combinations of reasons why this
is so and this book, used properly, should give you some or all of the tools
you need to diagnose and resolve your issue.
2. Which hip do you drop on the bike?
You mention, or more accurately,imply,that the more pain you are in whilst
riding, the functionally shorter your left leg becomes. That means that something
is pulling your left ilium up. The likely culprits are the psoas and QL on
that side. Does that sound correct to you?
3. When you are having a good day; i.e, pain free, have an x ray taken..
You need to be standing with both knees locked out. What I want to know is
what the relative heights of the femoral heads are. This doesn't need to be
a giant film. You just need a straight on shot of the pelvic area to determine
femoral head height and a side on shot to determine whether either ilium is
posterior or anterior to the other.
4. Do you have a history of digestive disorders or food allergies?
Do you feel bloated after certain types of food.
5. How dissimilar are your feet?
Is one significantly longer or wider than the other?
Do you have a callous under the 5th MTP joint on either side?
Do you have a lower arch or do you pronate more one side than the other.
Do you have a larger 1st MTP bunion on side than the other.
Does the big toe point on one foot point away from the centre line of your
body more on one side than the other.
6. Do you know any people with a talent for observation?
It probably helps if they have some sort of anatomical knowledge. Wait until
you are having a 'good' day. Set your bike up on an indoor trainer making
sure that the bike is leveled between axle centres and warm up thoroughly.
15 minutes working up to around 80% Max HR is good.Once warmed up set a resistance
and cadence that you can sustain with effort for say 10 mins..You will need
your shirt off. I need your observer to tell me ( and he/she will need a chair
or stool for some of this) -
a. Which hip do you drop and / or which side of your pelvis sits forward under
light load while warming up?
b. Once you are riding hard and starting to fatigue, does the degree of hip
drop/ rotation change markedly?
c. What cadence are you doing
If so how?
d. When you are fatiguing, I want your observer to focus on your lumbar spine.It
is likely that it moves more to one side of the centre line than the other.
Which side?
e. Do you lock on elbow more than the other and do you thrust one shoulder
further forward than the other?
f. Is there any obvious difference in pedaling technique between sides?
Let me know the answers to all of that and maybe we can make some headway.
Iron deficiency
My stats:
Male, 58 years old, cycling for six years in NH, March - November, hit the
gym weights four days a week all year round. I cycle about 150 - 200 miles per
week in season and race maybe three times a year in 20 - 60 mile road races.
My weight is 137 - 148 pounds depending on season and body fat is 7.5% - 12%
again depending on season. My current weight 138 pounds and body fat is 7.5
- 8.5%. The numbers vary widely daily but are trending downward and I'm looking
for about 6.5 - 7.5% for a goal.
This winter I started spin classes for the first time and decided to work on
cutting out junk food and eating healthier. My goal is to get down to around
135 pounds while maintaining my strength. This winter I kept the winter weight
off for the first time ever and my weight stayed close to my season ending 138
pounds all winter long. I've switched over to all 100% wheat grains in any pasta
or breads I eat, lots of fruit and try to graze all day long in addition to
making a fruit shake with milk, fruit juices fresh fruit and added protein mix
daily.
My problem is I always seem to be slightly iron deficient. Even when taking
a multi vit. My doctor has told me to take an iron vit of 325mg 3 times a day
for the next 6 months. Do bikers tend to run on the low side with iron? Will
a slight iron deficiency affect my performance at all? I try to eat a good variety
of foods and lots of salads with baby spinach …
John Cahalane
Dave Fleckenstein replies:
This is an topic slightly out of my area of expertise, but I do have some
personal experience in dealing with iron deficiency. Interestingly, my iron
issue was first revealed through a significant progression of restless leg
syndrome, in which iron deficiency is thought to play a role.
First, have a specific panel run to determine your current iron state. Second,
iron is absorbed best on an empty stomach, or in combination with an acid
and vitamin. My regimen is to take my supplement with a small glass of orange
juice first thing in the morning and then eat breakfast a little later. Finally,
iron is toxic in high doses, so make sure that you run a follow-up panel to
monitor ferritin levels, etc…
After obeying the rules of iron absorption, I have found my RLS symptoms
have decreased and I do feel better on the bike.
Again, I defer to anything that Pam would add in, but I have encountered
enough athletes with these issues that self-manage incorrectly that it is
worth adding my novice observations.
Pam Hinton replies:
What tests have you had to determine your iron status? There are several
indicators of iron status, and they look at different aspects of iron metabolism.
Hemoglobin and hematocrit look at the functional iron in red blood cells,
while ferritin is an indicator of iron stores. Hemoglobin and hematocrit are
used to diagnosis anemia. Ferritin is used to determine if your iron stores
are depleted and you are at risk for anemia.
There isn't much information on the prevalence of iron defiency in adult
male athletes, just because it's so much more common among women. We did do
a small prevalence study (n=120) in endurance athletes--mostly cyclists and
triathletes--several years ago. We found that ~5% of men had iron deficiency
without anemia compared with 35% of women.
You didn't mention any meat in the description that you provided of your
diet. Are you a vegetarian? Meat is the best dietary source of iron because
it contains heme iron, which is much more bioavailable, i.e., better absorbed,
than non-heme iron. Only a very small percentage of non-heme iron, which is
the type of iron in plants and dietary supplements, is absorbed. So, if you
are a meat-eater, increasing your intake of lean red meat is another way to
increase your iron intake.
If you decide to take the iron supplement, be sure to follow up with your
doctor in a couple of months. Iron cannot be actively excreted from the body,
so it can accumulate to toxic levels. Your doctor will be able to monitor
your iron status and determine when the supplement is no longer needed.
John Cahalane then responded:
David,
Thanks for the advice. I've started researching on line and I've found a lot
of good info. This is my second time with this issue a couple of years ago I
had it as well but it was never to the point where my physican was concerned
about it enough to do anything but recommend iron vitamins and retest.
If I get on a good vitamin and eat correctly (right foods and combos) it has
gone away in the past. I do a lot of hitting the gym weights as well as riding
and I've read where this can cause a loss of iron. But heaven forbid I change
that at all. Off to get vitamins this weekend and start the vitamin C routine
as foods as well.
Pam,
My doctor took blood samples and determined I was low via that method. Is there
anything specific I should ask? From what you said below I'm assuming I should
be asking about Hemoglobin, hematocrit and Ferritin as a starting point.
I'm not a vegetarian I eat a lot of chicken, 6 egg whites every morning, top
round steak a couple times a week. Usually chicken or steak at least once a
day. It's not unusual for me to have chicken or steak at night with a really
big salad with lots of things in it.
My doctor wants me back in 6 months to run another blood test.
I read on the internet that recommended daily allowance for iron is 10 milligrams
for men yet he has me taking 325 mg three times a day. Something seems way off
here. Maybe what I read online (10 milligrams) is incorrect as it was just from
a forums post by someone.
Commuting & recovery rides
Knowing full-well the benefits of recovery rides, I'm curious to know if there's
any evidence that several shorter rides can be as beneficial as one longer ride?
My daily life has me commuting short distances (about 15-20 minutes) several
times most days, and I'm wondering if it's possible these can serve as recovery
rides, assuming I keep the pace nice and easy. If I log 45-90 minutes in a day
with these short rides, would they equal (or come close) to 45-90 minutes of
recovery riding, or should I get out and do a 'regular' recovery ride on top
of this (on the days I ought to do a RR, of course)?
Thanks for any input,
Dave Shishkoff
Victoria, BC Canada
Scott Saifer replies:
Great question. The purposes of a recovery ride include dilating blood vessels
so that blood can flow into muscles to provide nutrients and carry away wastes,
and also to stretch the muscles through their normal range of motion. Both
of those are well accomplished by a 20-minute ride.
A 20-minute ride does not do much to enhance competitive fitness since you
are essentially training to warm up repeatedly rather than training the energy
systems that are used when you are already warmed up. For instance, by 20
minutes into a ride, your body is just beginning to mobilise fat for use as
a fuel so a series of 20 minute rides won't train fat metabolism like a longer
ride. For recovery though, little doses of riding will work.
Shorter leg questions
I contacted you a few years ago about an issue, but wanted to find out a bit
more on another subject.
I have been riding with orthotics in my cycling shoes, and today have been
told my right leg is much shorter than my left. I have now put a 7mm shim in
my regular shoes. We might be going all the way up to 10mm or 1 cm. I am using
175mm cranks on both road and mountain.
I am using look keo pedals on the road. Should I put a few lemond wedges under
the cleat and then add more to the orthotic inside?
What do you do with time atac pedals?
Cheers and thanks for assisting cyclists around the world.
Stuart Laing
Eddie Monnier replies:
Do you know if the 10mm shortage is in the tibia, femur, or a combination
thereof? The reason I ask is it affects the amount of stack I would recommend
to use. If your shortage as all tibia-related, I would try 5mm of stack (half
the shortage). If the shortage is in the femur, than I would try about 3m
of stack.
Steve Hogg replies:
By the sound of it, you are looking at a large shim under the cleat of the
right shoe. If you are using a 7mm lift and contemplating 10mm in your walking
shoes then it is likely that you will need plenty under your right cycling
shoe. You can make a shim yourself or you can use BFS cleat wedges (formerly
Lemond wedges) in a counterstacked fashion, though the number you are likely
to need means that there is the risk of them slipping unless glued together
and having the cleat fixing screws torqued very tight.
Alternately get hold of purpose built ones. If you elect to do the latter,
contact BikeFit Systems in Seattle. They have 3mm shims of my design for just
this purpose. The key with a large shim is that the larger the shim, the greater
the metabolic cost of stabilising foot on pedal with the shim stack. The solution
to this is to move the cleat further approximately 1mm further back relative
to foot in shoe for every 5mm of shim stack. Sometimes more than that is necessary.
What you are looking for is a similar feeling of fluency for both legs with
shim stack in place.
This may not be achievable with Look Keos on some shoes. If you run into
problems, change to Speedplay pedals and use Speedplay part no. 133300 which
are a pair of aluminium adaptor plates that replace the standard plastic ones
and have much more rearward adjustment potential than the standard version.
Lastly, with your Time ATAC's it isn't practical to shim up an mtb cleat
more than 5mm or so because of the relatively small contact area. The best
solution is to use your road shoes to determine the best size shim stack.
Once you have done that, find a good bootmaker and have them remove the sole
from your right mtb shoe; fit a full length build up of dense EVA foam to
the underside of the upper and then reglue the sole. Properly done, at a glance
it will be indistinguishable from a standard shoe.
Distance between pedals
It seems to me that riders come in different heights, weights but also widths.
Shouldn't riders of different hip width have a different pedal width?
Giovanni Reggioli
Eddie Monnier replies
A proper fit assesses many aspects and one is certainly the rider's horizontal
alignment of knee and foot. For many riders, we can achieve the proper stance
width by moving or manipulating the cleat. Sometimes when we need to move
the feet out to position them under the knee, we add a washer to the pedal
spindle.
There are even adapters called Knee Savers for much large corrections (unfortunately,
they only work with pedals that tighten using a pedal wrench). Speedplay recently
came out with pedal spindles of varying lengths allowing a great deal of customization.
Finally, sometimes we change cranks as there are variances in crank width,
so that's another area to possibly address.
Mountain biking and back pain
I have a question about mountain biking and back pain. I've been training and
racing road and mountain bikes seriously for 3 years and have had problems with
my lower back.
I'm 6'4" tall and ride a 62cm road bike and 21 inch mountain bike. When I ramped
up my training three years ago I was struck with a bad back injury that kept
me off the bike for three months. After lots of physiotherapy I was told I had
weak core muscles, poor flexibility in back/hamstrings and a slight scoliosis
in my spine. I now work my core twice a week (static and functional exercises)
and stretch pretty much every day as well as using a foam roller once or twice
a week.
Most of the time I dont have any back pain at all. I can do a 5-6 hour hilly
road or mountain bike ride without problems. They only time I seem to suffer
is when I race my mountain bike or when it's exceptionally bumpy. The way I
would describe it is chronic back fatigue, it is really quite painful and I
loose the ability to push hard on the pedals. I ride a Scott Scale carbon, 21
inch. Last year it happened on two long bumpy climbs in a 90km marathon race
and this year on a flat bumpyish race course after one lap. I have had the bike
two years and have tinkered with the position and feel I have it dialled.
I keep on top of my flexibility daily and feel the core work has really improved
my efficiency on the bike. I have been thinking of getting a full suspension
race bike to try and get rid of this back fatigue. Do you think this would help
or is there anything else you could suggest?
Michael Coward
Steve Hogg replies:
This is an interesting problem that you have in that most people who own
an mtb and road bike have more problems on the road bike than on the mtb.
The more prone position of the road bike tends to exaggerate the effects of
any structural shortcomings the rider has but your experience is the opposite.
So that leaves me wondering why your back gets a workout on bumpy courses.
Possible reasons are a lumbar spine that is too flexed; either because the
seat is too bar back, the bars too low or the reach from seat to bars being
too short. Equally it could be a reach to the bars that is too great. Do you
find your self creeping forward on the seat under high load for sustained
periods?
If so, something is compromising your stability on the bike - seat height
too high or an overly long reach to the bars are the obvious possibilities.
Does any of this strike a chord?
Michael Coward then responded:
Steve,
Thanks for the reply. When I first bought the bike it had flat handlebars and
as I had to have the saddle up high the drop to the bars was quite far, I now
run riser bars, the drop from the saddle to bars is 85mm, does this seem like
a lot for racing? I dont feel like I'm reaching too far for the handlebars,
my flexibility has improved quite a lot and I feel comfortable on the bike.
The only time I find myself sitting on the tip of the saddle is climbing on
the mountain bike and going really hard on the road bike; for example, when
chasing someone down in a race, as we say 'on the rivet'. It may also be worth
mentioning that I have all my saddles with a slight angle down tilt, I did this
originally to ease pressure in the lumbar region of my back, it is something
my physiotherapist (also a cyclist) suggested and seemed to work.
I also spoke to my physio after my latest bumpy race and he suggested that
the saddle could have been too high. It's quite frustrating when the legs and
fitness is good, I'm riding well then the back gives up.
Steve Hogg replies:
Whether 85 mm is too great a drop between seat and bars on your mtb is impossible
to tell via email. A couple of things though. I except that it is 'normal'
to slide forward on the seat of an mtb on steep climbs in lower gears just
to keep the front wheel down, but you mention being 'on the rivet' (moving
forward on the seat) on your road bike during severe efforts as though it
were normal.
For mine that is abnormal and always a consequence of a less than ideal riding
position or compromised degree of structural function or both. Even on an
mtb, longer than 'normal' chain stays can make is less necessary to slide
forward on the seat when climbing because the further back the rear axle,
the harder it is to rotate around it.
Assuming you run the same seat on both road and mtb, your mtb seat height
should be lower. I say this because some people think they should be the same
and usually end up with problems on the mtb. You have problems on bumpy courses
on the mtb but don't have problems at lesser loads on mtb or road bike. Seeing
as your physio has mentioned seat height too, why not drop it 5mm and reassess?
Changes in maximum heart rate
I raced regularly from my teen aged years until around the age of 35. At the
point I stopped my max heart rate was around 190bpm. Just "cruising around"
at 150bpm was almost no effort and in serious climbing I could hold 180-185
bpm for quite a while.
Now fast-forward 15 years to today at age 49. I have started back into serious
riding again and I am finding that my max HR seems to be 170-175 bpm. 140 bpm
is quite comfortable but at 160 bpm I am really huffing and puffing. So, my
question is: is this just a normal part of getting older?
On a sustained climb I can put out 300W on my PowerTap at about 155bpm. Do
you think that this change in HR is due to age or just being out of training
for so long? Will this improve over time as I get more miles under my belt?
Dave Walker
Central Point, OR
Scott Saifer replies:
Conventional wisdom says you should expect to lose 0.5 to 1 bpm off your
maximum heart rate each year as you get older. That would explain the drop
from a max of 190 to 175. Hitting your ventilatory threshold somewhere below
90 percent of max (below 160) is also expected. Well trained athletes don't
"huff and puff" however, they breath more deeply and more rapidly. If you
are really gasping, that would be a sign that you need to regain some fitness.
Dave Walker then responded:
Scott,
Thanks for the amazingly quick reply! I didn't literally mean 'huffing and
puffing' but, rather, a change from deep regular breathing to deep but much
faster breathing. It sounds like it is just what is expected. So, I guess that
I need to just live with getting older and keep working on fitness.
Scott Saifer replies:
When you say "much faster breathing", that sounds like you are describing
hyperventilation. Currently well trained athletes don't do that. They breathe
deeper and a bit faster, but not a lot faster. The problem with too rapid
breaths is that they don't exchange air deep in the lungs. Well trained athletes
achieve an efficient balance of deeper and more rapid breathing that does
effectively exchange air from deeper in the lungs. You can learn to do this
voluntarily, but it also happens automatically when you train consistently.
Leg length discrepancy
I recently fractured my hip and had it repaired with screws (they used the
loose ones from my head). The doctor says as per the x-ray that my leg is 1/2"
shorter now than before. The fractured leg was already a bit shorter.
I know you can use spacers between the Look cleats and shoe sole. I use regular
Look pedals but have two sets of Keos that were sent to me for warranty issues
with the older ones. Because the Keo has less stack height can it be used on
the longer leg and an older Look pedal be used on the shorter leg?
I want to avoid too many shims as I understand it creates instability. Also,
is using two different crankarm lengths a good way to resolve this?
Thanks for your help always and your innovative approach to fitting.

Steve Hogg replies:
Eddie and I will have to agree to differ on this one. My experience is that
it doesn't matter about establishing where the discrepancy in leg length is
because that knowledge is only important if a formula response to it is planned.
I think it best to take individual cases on their merits.
To that end, what matters most in accommodating a leg length discrepancy
is that the rider sits as squarely as possible on the seat and has both legs
reaching through the bottom of the pedal stroke with comparable power and
control without their being problems on either side at the top of the pedal
stroke. With that background, let me address you concerns:
"Because the Keo has less stack height can it be used on the longer leg and
an older Look pedal be used on the shorter leg?"
Yes. There are two potential negatives with doing this. The first is that
you then have a fixed 'effective' shim height. This may be too much or too
little in your case. The second potential negative is that the weak point
of all Look Delta cleats is that the contact point of cleat on pedal is also
the contact point of cleat on ground when you walk on them.
That means that over time the Delta cleat abrades giving rise to vertical
slop between cleat and pedal and a lower 'effective' shim height as the cleat
wears. By contrast, Keo cleats have walking 'platforms' at front and rear.
The area the contacts the pedal does not contact the ground until these walking
platforms are abraded away after which is it is good idea to replace the cleat
anyway
You need to understand that there is no difference in stability between using
an older Look pedal and cleat as an 'effective' shim of 5 - 8mm (depending
on which Keo model of pedal and cleat you are comparing to which Look Delta
model of pedal and cleat).
"I want to avoid too many shims as I understand it creates instability."
That statement isn't correct in the context that you have used it. The pedal
axle moves 360 degrees through a circle as does the foot on the pedal. They
are separate and translated circles in that the foot sits above the pedal
axle and so doesn't move through the same circle as the pedal axle.
The closer to matching each other that these two translated circles are the
better in the sense that it takes less effort to stabilise foot on pedal when
the two circles are closely matched than if they are not closely matched.
That is why pedal manufacturers have reduced the effective height of their
pedal/ cleat systems and shoe manufacturers have reduced sole thickness over
recent years.
When you use two different pedal/cleat systems to form an effective shim
on one leg, there will be no difference in stability of foot on pedal of the
shorter leg than if a shim of the same 'effective' height is used. The only
caveat that I'll place on that is that the shim is larger than the cleat and
provides an effective platform for the cleat. You can make one from any suitable
material or you can purchase pre made ones in varying thicknesses.
The other advantage of using a shim or shims is that the height of the shim
stack can be varied easily, whereas with two different pedal systems you have
a fixed non adjustable 'effective' shim with no ability to experiment (other
than to add a shim!).
Shimming a cleat does create a greater demand for stabilising foot on pedal
than not shimming but the way around that is to move the shimmed cleat back
1 mm or so for every 5 mm of shim height that you use. Of course moving the
cleat further back on the shimmed side causes a fraction more leg extension
on that side, but somewhere in there is an effective compromise.
"Also, is using two different crankarm lengths a good way to resolve this?"
Not unless all other options have been exhausted and having differing crank
lengths is the least worst option left of only bad options left. You have
different length legs that at some level are going to have to work at different
levels of muscular contraction to produce the same amount of torque on each
side. Why add to that difference by introducing differing crank lengths?
That will only place a greater demand on the shorter leg pushing a shorter
crank if the desired outcome is both legs working as evenly as possible. They
won't ever be the same because of the leg length difference and likely other
functional and neurological asymmetries between left and right sides, but
I see no value in increasing asymmetric function unless it is a better option
than alternatives. A shim or shims is the best option. If by lucky coincidence
the shim stack you need is the difference in stack height between a Keo and
Delta pedal, then that will work fine. If not, use a shims or shims.
Best of luck and thank you for the positive thoughts.
Recovering from Colles fracture
I wrote a couple of years ago about sprinting, and you guys were a tremendous
help... I'm a cat 3 woman - racing age 40 - no road racing last season due to
a major surgery in my family last summer - cross season was a blast, though.
This road season was supposed to be a sort of comeback season, if you will.
On March 1, I hit the deck playing hockey with my child and sustained a Colles
fracture - actually - I also broke off that little pokey part on the tip of
the Ulna as well. I had a cast for one month. I've been cleared for training
and racing with a wrist brace. I borrowed a recumbent bicycle for about three
weeks after the fracture and used my trainer with my road bike. Now, I've been
riding my upright bikes for almost three weeks. I have done two local spring
crits.
My problem is soreness and weakness. All those muscles that run parallel to
the ulna pretty much disappeared during the cast-month. I've been working hard
to restore as much range of motion and strength as possible. I've got about
75% of my range of motion back... But, the lack of strength in those muscles
along the ulna side of my forearm is clearly limiting. I cannot get ideal leverage
on the handlebar, and after I hit fatigue in those muscles, I can no longer
even get decent leverage on the handle bar.
I get this funny cramp that runs from my wrist crease to my elbow at the point
of fatigue, and I have to say, this is... well... an unpleasant sensation (it
hurst like bloody ^&*$). Time to fatigue continues to lengthen.... I mostly
have difficulty with standing climbs and sprints.
So, my question is this - are their cycling specific exercises I should do
to improve strength/endurance?
Also, I'm about a month behind (at least it feels this way) in my training.
I was able to keep my base, but my "high end" really stinks. Any advice as to
how I might make a jump in that regard? And, I have to admit to feeling nervous
on descents.... I find it difficult to stay in the fold, so to speak. In fact,
at my crit of last night, I was dropped on the descent of the second-to-last
lap... So advice there would also be most appreciated.

That's great that you are already back on the bike and have a couple races
under your belt. I can address feeling nervous on the descents.
Sometimes when we are coming back from injury we feel a little more vulnerable
and fragile. Often our body has healed before our confidence has, so when
we get into situations where we think about the potential of getting hurt,
we elicit our stress response out of a fear of getting reinjured. It's your
brain's way of trying to keep you safe. Unfortunately in sport, it can have
the opposite effect - making you tense which means you have less balance,
less coordination, and are slower to process information and make adjustments
if necessary. All of these things make it MORE likely for you to get injured!
In your situation the nerves are coming out on descents. For other people
it might come out during the final sprint of a crit.
Since you've only been riding upright for 3 weeks, some of your confidence
will come back with time. The more experiences you have riding successfully
down descents at increasing speeds, your brain gets the message 'See - we're
fine. We can totally do this.' You can help speed up that message by doing
a little proactive work on your mental game. The 1st thing to do is to make
sure that your body is relaxed. Make sure that you are breathing. If you are
holding your breath while you are descending - it will send your body into
stress mode. So #1 - Breathe.
You can also remind your body to relax. Periodically during the descent,
remind yourself to relax your hands and face. Just focusing on relaxing those
two parts of your body will send a little message throughout the rest of your
body to relax as well. Next you need to work on relaxing your brain - which
means working on choosing your focus and your thoughts during the descent.
Keep your focus in the present moment and your thoughts on what your need
to do to descend successfully.
As you approach the descent, that's probably when the nerves start to kick
in. At that point your focus can be on your breathing and saying to yourself
'I have the skills and I'm confident in my ability to descend.' As you descend,
pick out specific things to focus on in order to descend smoothly. Focus on
your breathing, your positioning, etc. Your brain can only process one to
two pieces of information at a time. If you choose to focus on your breathing,
positioning, etc., you don't give your brain the space to focus on feeling
nervous. The more you practice, the stronger your confidence will become.
Midfoot cleat position data
My name is Jerry Gerlich and I have cycled since 1986. I began using Time clipless
pedals on a 1989 Somec Columbus SL frame and added some Shimano SPD pedals to
a Fat City Wicked ATB in 1990. Like many cyclists set up in a bike shop, all
of my cleats were positioned directly under the ball of the foot. I kept that
position until almost three years ago when I moved the cleat 10 mm back and
dropped the saddle a bit per your suggestion.
This made a huge difference in comfort. After reading your postings on Cycling
News I have been intrigued with the midfoot cleat position but like the rest
of the naysayers, I folded my arms and stood my "traditional position" ground
waiting for some peer-reviewed research data. After all, if the position is
so special, why don't we see the likes of Eddie, Lance, and Miguel riding with
their cleats in the middle of their arches?
My attitude began to shift in early 2008 when I read Joe Friel's blog about
the position. Joe, like yourself, seems to know a thing or 2 about cycling and
bike position. Then there was another shift in early November of 2008. I watched
my 7 year old son riding up and down the sidewalk.
At that age, heart rate, watts, efficiency and recovery are not even in your
vocabulary. But, there he was, going as fast as he could with his foot centred
on the pedal. I generally don't take too much cycling technique/position advice
from kids too young to ride in the front seat of a car but I noticed how fluid
his feet and legs were moving. So, I took the plunge and sacrificed some old
ATB shoes to the midfoot cleat cause and the adventure began.
After a few days of measuring/marking/measuring/marking/measuring/marking,
I started drilling holes. The first few rides were a little iffy. I had to get
the position right without the shoe hitting the crank and the cleats making
too many creaking noises. After 3 trys, 11 cleat wedges and about a half of
bottle of Gorilla Glue, I found the non-creaky wonderful new midfoot position.
WOW! I enjoyed the position so much that I immediately began measuring/marking/measuring/marking
my $250.00 Diadora road shoes get to try and get to a midfoot position on my
Time RSX carbon pedals. The timing of this experiment could not have been worse
as I had promised a friend that I would ride the Tour Das Hugel, an Austin area
century climbing festival, just 10 days away. To make a long story short, the
ride went awesome and I was chuckling to myself as we went up each of the hills
in the Austin area. The ride was windy and my bike felt really solid as I had
lowered my saddle by 35 mm.
But, what about some data? I work at a local Austin gym (Castle Hill Specialized
Fitness) where we have a small bike shop and an awesome cycling simulator called
a Velotron. For those readers not familiar with a Racermate Velotron, it is
the big brother to a Compu Trainer. The Velotron data report is identical to
a Compu Trainer's report. The Velotron ergometer measures actual electrical
watts via the rear wheel running through a box containing electromagnets. Thus,
the Velotron is the most accurate commercial watts-meter currently available.
We have been using this unit since 2003 for fittings, testing and training.
I have attached two Racermate Velotron data reports comparing my personal forefoot/midfoot
cleat positions. The report is based on a 8.79 mile simulation ride of L'Alpe
d'Huez. The graph illustrates a middle, pinkish heartrate line, a lowest green
watts line and a highest, purple Spinscan analysis line. Spinscan is a measurement
of the fluidity of a rider's pedal stroke. As a rider produces a higher Spinscan
number, he/she is turning over a smoother pedal stroke. For those of you interested,
my threshold heartrate is around 152-156 bpm at 270-280 Velotron watts. I have
been told that the Velotron watts feel 15-25 watts higher than an SRM (250 Velotron
watts feel like 270-ish SRM watts).
The first graph, from June of 2008, shows a ride time of 1:06:46 with an overall
average Spinscan of 89 (90 for the left leg and 88 for the right) was performed
with the cleat 10 mm behind the ball of the foot. The second graph, (midfoot
ride) from April of 2009, shows a ride time of 1:02.06, roughly 4:50 quicker
than the 2008 ride . Upon inspection the average heartrate is a bit higher 151
bpm compared to 146 bpm for the previous ride. However, peak heartrate is only
2 beats higher on the quicker ride. The real difference between the 2 rides
shows in the Spinscan analysis. The quicker ride shows 97 for both left and
right legs. This is an indication that things flowed much better. At a casual
glance, most should notice that watts, heartrate and Spinscan are more consistant
on the quicker ride. Here's the kicker, the faster ride felt easier on the body
in general. Get rid of all of the technology mumbo jumbo and I would still keep
the midfoot position because my hamstrings are sore after rides and the quads
and gastrocs feel awesome. And the unintentional icing on the cake is the higher
speed handling improvement now that my 6'3" body is sitting 35 mm lower into
my Pinarello carbon frame.
The midfoot position is not a be all/end all for everyone. Folks not exposed
to toeclip overlap will have a wake up call on where to have the feet when doing
u-turns. This issue works itself out within a few rides. Anybody with experience
riding a track bike should figure this issue out quickly. The front of the foot
will come closer to the ground while pedaling through corners. I felt my foot
scrape the ground a handful of times so I just slightly adjusted how and when
I pedal through the corners.
This issue reminded me of learning how to pedal through the corners with clipless
pedals years ago... just pay attention and listen for a little scraping sound.
Since the calf muscles are just about shut down in the midfoot position, sprinting
ability is reduced. However, my sprint packs as much punch as a handful of glitter
so I never relied on sprinting in the first place. I am more of a distance type
rider who motors along the whole time. Since things shift forward as the saddle
comes down, the stem may need to be lengthened and/or lowered to maintain the
same back/knee/elbow relationship.
Thanks so much Steve for your suggestion to move my cleats to the center of
my arch. Like yourself and Joe Friel, I will stick with midfoot from here on
out. My legs feel better, my back feels better and my shoulders feel better
as well due to the fact that I'm using less upper body to steer. My efficiency
is up and my heartrate is down. I know this is not published, peer-reviewed
data but I do have degree in Kinesiology from the University of Texas at Austin,
have worked extensively with the Velotron simulator (modified with a Mikkelsen
sizing frame) since 2003 and have performed somewhere between 2,500 and 3,000
bike fittings since 1989. Thanks for reading this far and have a great day.

Steve Hogg replies:
Thanks for taking the time to commit your experience to print. Yeah, I'm
a convert, some of my customers are and they have had similar experience to
yours. In some, the improvements are greater and some lesser. Some show no
improvement in heart rate vs output but anecdotally at least, recover more
quickly from hard rides or hard efforts within a ride.. So midfoot is a valid
choice if a rider wants to go to the trouble. It is a pity that some larger
cycling shoe manufacturers don't offer a shoe with midfoot drillings as an
option. It would make plenty of riders life easier as well as encouraging
more to experiment.
The real credit for this shouldn't go to Joe Friel or me though, but to a
German gent named Gotz Heine. It was through meeting him that my curiousity
was tweaked enough to experiment. I think Joe Friel also met Gotz and had
a similar experience. Gotz Heine has some very interesting and simple ideas
for improving cycling performance without drugs and deserves a greater audience.
Maximum heart rate
I am a 45 year old club cyclist of average standard. I started cycling again
after a 20 year lay off about 8 years ago. I have been delighted with my achievement
having set a PB for a 10 mile TT of 22.49 and 57.37 for a 25. I have seen my
max heart rate once at 190 but accepted 185 as the norm. I would expect to time
trial at 175.
In the last couple of years I have struggled to achieve my best and to sustain
a max heart rate of more than 165 and my legs feel, tired and stiff just after
starting a TT.
Significant changes to my cycle habits which might have had an impact are;
1) I changed clubs two years ago and my riding regime changed from: October
- December for winter miles January - March for winter miles and a high intensity
30 miler and turbo during the week then racing To: October - March for pretty
hard Saturday ride of 65 miles, an easy Sunday ride while introducing midweek
turbo session in the new year then racing from March
2) I used to train with my son who stopped riding for a couple of years. He
was a competitive training partner
3) Large family and commitments
4) Run a business which in current climate has been quite stressful but I have
always coped with this
Other issues:
a) I have less motivation now to race but love riding the bike, not sure whether
the motivation to race came after the drop in performance or the other way around
b) I am constantly fussing about position and I am preoccupied by this when
riding which does possibly effect my 100% focus on performance training. I feel
that I have got on top of this but may need a good deal of gentle mileage to
re-educate the body.
Resting heart rate normal at about 48 beats.
As I say I love just riding but on the last couple of performance efforts I
feel like throwing my bike in the ditch!
Any efforts appreciated.

Scott Saifer replies:
There's a good chance that you rode too hard through the winter and are now
paying the price. Riders can usually go hard (above LT long enough to get
tired) one or two days per week for about four months with a good base before
they burn out. Three days or more hard and they burn out sooner. It sounds
like you used up your hard months for the year over the winter. Could be?
If not, write again and we'll sleuth out what actually happened.
