Lactate threshold heart rate

Knee problem update
Lactate threshold heart rate
I'm a 36 year old just getting back into cycling after a 15 year hiatus. In
the interim, I still stayed fairly active through organized sports, running,
erg-rowing, and regular weight work. I've now been back on the bike for a year.
In any case, I'm becoming more and more confused about lactate threshold heart
rate (LTHR) the more I learn; the methods of estimating LTHR appear counter-intuitive
In at least two of the methods I've read about, it states that one's average
HR during a field test (or specifically say the average during the last 20 minutes
of a 30 minute test) is a decent estimate for LTHR. Training can then be based
around percentages of this figure.
The problem is that it is commonly understood that training obviously lowers
one's average HR for a given piece of work (after riding the same route for
a year, at the same pace, my average HR is lower now, my PE also lower) but
that I was also under the impression that training also, over time, raises LTHR.
In other words, through proper training one can raise the LTHR slightly, in
essence putting off or delaying the onset of anaerobic energy needs (and fatigue)
for a given piece of hard work. How can these two things be true?
The problem is, if I had tested for my LTHR using these methods a year ago
I was have gotten a much higher estimate than I would today, but I'm clearly
crossing that threshold less now (unless intentionally trying to do so). What
Thanks, and again, Happy '05
Eddie Monnier replies:
Using data from a field test like an all-out 30-min effort in training is
a common proxy for estimating one's lactate threshold (LT). For readers unfamiliar
with the LT, you might want to read http://velo-fit.com/vffaq.htm faq1 . Understand
that in a lab-based test, they actually draw blood to measure lactate levels.
But in field tests, we have to have some proxy and these are commonly either
heart rate and/or wattage. Heart rate is subject to many variables, both internal
and external, and so it's a good idea to look at trends over time.
Furthermore, LT is responsive to training and will change with increases
or decreases in fitness. You are correct in that some people, like myself,
realize lower heart rates (but put out more power) in these tests as fitness
gains are realized, while others may achieve higher heart rates (but also
put out more power). This is one of the reasons why I advocate periodic testing
(every four weeks or so) and why for many, laboratory testing (where lactate
is actually measure by drawing blood) is infeasible.
So, make one of your New Years resolutions to incorporate periodic testing
into your training approach.
Dario Fredrick replies:
Thanks for bringing up a challenging and interesting topic. Quite simply,
average heart rate (HR) for a 20-30 min max sustainable effort is a good field
test for your “performance threshold,” as it directly reflects cycling performance.
This maximal steady state (MSS) is the standard you should use to determine
your HR training zones. Since there are numerous methods for determining lactate
threshold (LT), and lactate is not a direct measure of fatigue (see this article
for more on lactate), the reliability of LT as a performance measure is suspect.
Lactate or LT need not even enter the picture.
Except immediately after coming off an extended period of no riding, your
threshold/MSS HR should not change much, if at all throughout the training
year. As you have experienced via a reduction in HR and perceived effort for
a given output, it is your power that has increased. Your HR values may not
necessarily have dropped in this case, you simply need to increase the workload
at the same HR to continue to improve.
You mention that you’ve heard that LTHR increases with training. Let’s look
at why this might occur. Keep in mind that when measuring blood lactate, we
are not measuring a fatigue-causing substance, but rather an important fuel.
Aerobic endurance training improves the ability to use this fuel effectively.
While there are numerous definitions of LT, let’s define LT as a lactate
value representing an intensity beyond which lactate begins to accumulate
in the blood. Using a hypothetical situation, let’s say you perform an LT
test (measuring blood lactate) which suggests your LTHR is 175 bpm at a lactate
value of 5.2 mmol/L. Six weeks later, after a quality cycle of training, you
repeat the LT test and at 5.2 mmol/L your HR is 183 bpm. Did your true performance
threshold (30 min MSS) HR go up? Not necessarily. There is simply less lactate
appearing in the blood at 175 bpm because you have improved the metabolism
(conversion of fuel to energy) of lactate directly in your muscles. Less lactate
is thus released into the blood at that level of intensity. This is one of
the reasons why a fixed lactate concentration (e.g. OBLA) is not a reliable
measure of performance.
We want to measure and predict performance, so it makes sense to use a performance-based
measure rather than a surrogate such as lactate or trying to estimate LT.
I would recommend sticking with your field test, ideally on a gradual, uninterrupted
climb if possible, or use a test protocol that accurately and reliably predicts
your 30min TT performance. Once you measure your performance threshold, that’s
all you need to effectively determine your HR training intensities.
Timing and intensity
Winter here in Montréal, an it's time to go back indoors. After a so-so last
season, I want to get a little more serious about my training to get better
results for next summer. Most of my races take place every weekend from end
of May to mid-July, with a couple more scattered in the late Summer-early Fall.
The average length is about 125 kms.
I've recently gotten back on the trainer, and am slowly building up my mileage
to get back that solid aerobic base.
My questions are as follows:
1 Will there be any difference in overall fitness results between one hour
a day every day on the trainer as opposed to two to three hours a few days per
2 If I want to peak in mid-June, when should I start adding more "intensity"
to my training?
3 If I take a spinning class from January to April, will that interfere with
the slow, base-building process I just started?
I'm 42, an enthusiastic amateur racer, in good shape and health, 6' and 170
lbs. I've been racing for four years now and I love it.
Michael Smartt replies:
First of all, you've taken the right attitude toward having your best season
ever in 2005 by grabbing the reigns now and having a little more purpose throughout
your "off season". Aside from the questions you have asked, I recommend looking
at just what you did and did not do in previous winters so that the adjustments
you make this year will be appropriate: that is to say, doing more this winter
sounds like a good plan, just make sure you don't add so much as compared
with previous years that you over do it. To your questions:
1. This question definitely spurs on that wonderful response of... it depends,
based on your racing goals, type of races (eg: road vs crit), etc. However,
I would recommend that you do both (daily short workouts and occasional longer
workouts), especially if the weather allows. Spending too much time on the
trainer at once is very daunting and not necessary for many different and
very productive workouts you can do on the trainer. On the other hand, it's
good to deplete the muscles via long(er) duration rides periodically to promote
various adaptations that occur when the muscles are somewhat depleted/fatigued.
2. "Intensity" can mean different things for different races/goals, but if
I assume you mean maximal steady state intensity and above, then 12 weeks
is a common block of time (that includes a few reduced volume weeks) where
you can progress from hard tempo/TT pace riding to VO2 max intervals, etc.
Again, the order/intensity/duration of "intensity" training will depend entirely
on the type of races you are targeting.
3. Absolutely not. The key is the overall balance between high intensity
(ie: spin class) and low intensity (ie: base miles) throughout your program.
A good way to get an idea of what that should be is to look at the overall
balance you have been able to maintain during your pre-season and within season
training in the past. So long as you keep the overall volume of high intensity
training relatively low and less frequent, you can build aerobic base while
attending a spin class. I, like many other coaches, do prescribe some form
of high intensity training during the winter months for all of my clients.
Keeping your aerobic ceiling relatively high (although lower than during the
season) will give you many benefits, no least of all the ability to perform
your base miles more effectively. My one caveat on this question would be
that when you join a spin class you should be aware of one key issue: most
spin classes are designed to just kick your butt, not necessarily train you
for cycling races or consider where you are in an annual training program;
if you can find one that is lead by someone specifically with cyclists in
mind, so much the better, if not, be aware that you will likely have to tailor
the intensity/duration of efforts/recovery periods/overall stress of the workout
to meet your needs.
Zone 2 training
It's that time of year again when many coaches and riders adhere to tight heart
rate limits ("Stay in Zone 2 or else"). I can certainly understand that this
is the time to spend your training "matches" doing more miles, since later workouts
will be higher intensity efforts (and necessarily shorter) and you won't have
the time, energy, or training slots to ride as many miles as you can do now.
That said, what damage are you doing (or maybe what benefit are you taking
away) from your aerobic system if you go a reasonable amount above "Zone 2"?
Due to cardiac drift, if you end up 10 bpm above Zone 2 at the end of 90-120
min at steady power (perhaps at elevated cadence to work on mechanics and stress
the aerobic system), isn't that still an aerobic effort? What's actually going
on down in the energy pathways and the physiology that make this workout bad
for aerobic development?
Staying slavishly in Zone 2 doesn't feel like doing any overloading and doesn't
that violate the first part of "overload and recovery"? I'm not advocating TT
efforts, but I'd really like to understand the physical reasons for the limit.
On a related note, I read about a "dead spot" above Tempo that is to be avoided
since it doesn't help training, but an explanation of the underlying physiology
why this is a dead spot and the metric used to identify the zone is missing.

Dario Fredrick replies:
We can examine your questions directly if we define training zones based
on muscle fiber type recruitment and corresponding energy pathways first.
Bear with me as I briefly define muscle fiber types.
Many cyclists have heard of slow (Type I) and fast twitch (Type II) fibers,
but few realize that fast twitch fibers are divided into two types, giving
us at least three distinct types (Type I, Type IIa, Type IIb). We recruit
these fiber types in that order (Type I >> Type IIa >> Type IIb) as force
increases from light to maximum.
Type I fibers are fuelled primarily via aerobic metabolism, can produce a
moderate amount of force and are very fatigue resistant. Type IIa fibers are
fuelled both via aerobic and anaerobic metabolism (ratio depends on how your
train them), can produce a large amount of force and their fatigue resistance
depends on the energy pathway used (aerobic/anaerobic). Type IIb fibers are
the highest force-producers, fuelled primarily via anaerobic metabolism (preferring
glycogen for fuel) and fatigue the most quickly.
If our goal during the base period is to maximize aerobic capacity, specifically
of the Type I and Type IIa fibers, we want to train at levels of intensity
that result in the desired adaptations. At Whole Athlete we use five training
zones, with the top of zone 4 representing a cyclist’s “performance threshold”
or maximal steady state (MSS) HR (MSS = 30min max sustainable). To maximize
training benefit using specific training zones, it is important to accurately
I’m not sure exactly how you define your zone 2, but for this explanation,
let’s define zone 2 as the heart rate that is 84(±4%) of MSS. This level of
intensity is where we recruit both Type I and Type IIa fibers, fuelling them
mostly via aerobic metabolism. Spending significant time in this training
zone improves the aerobic capacity and endurance of Type I and Type IIa muscle
To specifically address your questions, you ask what damage is being done
(or reduced benefit) to the aerobic system if you train above zone 2. If you
are in the early part of your base period (3-5 weeks), going above zone 2
forces the Type IIa fibers to rely more heavily on anaerobic metabolism for
energy. This in turn can reduce their aerobic capacity, increase their reliance
on glycogen for fuel and increase their rate of fatigue. On the other hand,
if you spend sufficient base period time in zone 2, adding zone 3 training
can ultimately increase aerobic capacity and power output. We advocate a periodized
progression of training phases.
Regarding your cardiac drift question, you can effectively train zone 2 by
spending the early portion of your workout in the lower to middle HR of the
zone 2 range, and allow yourself to be at the top of zone 2 closer to the
end of your workout. If everyone had the luxury of a power meter, we would
all see that early in a ride, zone 2 workload (power) tends to elicit a slightly
lower HR, while later in the ride the same workload produces a higher HR.
As you pointed out, higher cadences will tend to elevate HR for a given workload,
so if you are intentionally riding high rpm in a workout I would still recommend
staying within your intended training zone.
Regarding the training “dead spot” you mention, many refer to this level
of intensity as 94-95% of MSS HR (low zone 4). The only situation in which
it is a dead spot to be avoided is in the phase of the base period where you
are still working on maximizing the aerobic capacity in zones 1-3. There is
certainly a time to train at that intensity, but doing so prematurely can
potentially limit aerobic capacity and increase rates of fatigue, again forcing
a greater reliance on the anaerobic pathway for energy. Since we are always
using some combination of aerobic and anaerobic metabolism, the base period
is ultimately about maximizing the aerobic component for a given workload.
Michael Smartt replies:
Yours is an excellent question, especially as you have already touched on
some of the reasons why "stay in zone 2 or else" as a universal training plan
for this time of year (we'll call it "base") is not applicable to many if
not most cyclists. Yes, zone 2 training is the corner stone of most road cyclist's
program, but such a strict regimen does not take into account your available
training time, training/racing background, goals for the next season or current
strengths and weaknesses.
As to the physiology of zone 2 training (or slightly above) let me start
by saying that at RST, zone 2 is equivalent to just below most cyclist's Lactate
Threshold (LT: defined as 1 mmol above baseline) or ~60% of VO2max. For steady
state efforts, a significant anaerobic contribution does not occur until you
get over 80% of VO2max (and even higher for elite cyclists). So in terms of
steady state work above zone 2, you have a long way to go before you induce
any "negative" effects on aerobic endurance from a significant anaerobic contribution
(namely metabolic acidosis, which can reduce aerobic endurance when induced
often and severe enough). However, due to the lag time in the heart rate response
to changes in intensity/power, the recruitment of anaerobic muscle fibers
will not be apparent when making short (<20sec) surges or accelerations. These
short efforts (such as holding your momentum over a roller or accelerating
out of a corner) are not enough to induce metabolic acidosis and are not seen
as a problem by many coaches. In fact, I would suggest that such efforts are
very specific to the demands of road cycling.
Can zone 2 induce overload? Absolutely; if you have a lot of time to go out
and train for several hours on a regular basis. For an elite cyclist who needs
to be comfortable spending 5-7hrs on the bike, long days in zone 2 are very
appropriate for inducing the appropriate physiologic response and adaptations;
the primary ones being increased mitochondrial density, lactate threshold
and muscle glycogen storage, among others related to aerobic capacity and
endurance. For a Cat 4 cyclist who works full time and will not do more than
a 45min criterium, achieving overload via zone 2 training alone is not going
to happen; never mind the lack of training specificity for such a scenario.
RST does not advocate the "dead spot" you refer to. Every intensity from
zone 1 to sprinting has more than one physiologic adaptation associated with
it; this is due to the spectral nature of the overall physiologic response
to exercise and the interwoven nature of the three energy systems (i.e.: recovery
from anaerobic efforts occurs via aerobic metabolism). Understanding the adaptations
that occur as a result of training within each zone and how they apply to
your performance goals at different times of the year has more relevance and
application than the concept of avoiding a subjective "dead spot".
Very long toes
Here's another cleat position question for Mr. Hogg.
What can I do if I'm unable to move the cleat far enough back on my shoes to
place the ball of my foot in front of the pedal axle? I have received more that
one comment that I have extremely long toes for my foot size. I wear a size
44 usually, but with "normal" toes, I'd probably be a 43 with room to spare.
Do any of the other pedal systems automatically place the foot farther forward
than my SPD-SL's?
Steve Hogg replies:
Firstly, what shoe brand and model are you using?
If using Carnac in the smaller or medium sizes, the current Time shoes, Adidas
or Pearl Izumi then your shoe choice puts you at a disadvantage from the start.
These brands have cleat mounting hardware that is further forward on the shoe
than many other brands. Shimano in their better shoes, Nike, DMT, Sidi, Gaerne
and Specialized all have more rearward cleat mounting hardware than the 4
brands listed above. Of the 6 just mentioned, Nike and DMT are probably the
best in terms of rearward cleat mounting potential. They have different uppers
but use the same carbon sole.
If you are using one of those 6 and still have the problem then the ideal
solution is to have shoes custom made and explain to the maker exactly where
you want the cleat mounting hardware. I don't know where you are, but here
in Oz a custom pair of shoes costs a little less than the top of the range
models in some of the Euro shoes.
If that is not an option, a pair of Shimano SPD road pedals, if you can find
them will allow you 10mm or perhaps a bit more foot over the pedal, assuming
your shoes have the hardware to mount SPD's. Keywins will also give you another
5 mm or so more than your SPD- SL's. How much more cleat movement rearwards
do you need?
Another possible solution, is if you change to Speedplays, they don't have
as much rearward adjustment as your current pedals, but I have some alternative
baseplates that will allow another 14 - 15mm of rearward adjustment potential
than the standard baseplates.
[Mitchell replied that he is using Pearl Izumi Vortex shoes.]
Your Pearl Izumi shoes have the cleat mounting holes approximately 10 mm
further forward, size for size than the 6 brands I mentioned above. Long toes
or not, the Pearl Izumi cleat placement makes it hard for a majority of riders
to achieve any cleat placement that I would suggest to a particular rider.
Steve Hogg had this comment in a recent response:
"At the end [of a 40km TT] ask yourself if you feel any pain or knots high
in the hamstring under the glutes? This is a common tell tale if the seat is
just a little too high."
I regularly get knot-like pain deep in my hamstrings, but not at the end of
a ride, rather, after about 5-10 minutes at "tempo". After about another 10
minutes the pain completely fades and there is no pain at the end of the ride.
I am well warmed up and it doesn't depend on temperature. It does seem to depend
on whether I am in the drops or not (road bike), and bigger gears appear to
make it worse. I sit quite a long way back in the saddle, have been on and off
the bike over the years, and it only seems to be a problem when I'm in decent
The problem is on the inside of my thigh, about 4 inches below my groin. When
sitting on the bike it's roughly lined up with the nose of the saddle (and this
has happened with multiple saddles). When I said deep, I was thinking in terms
of sitting on the bike, where it's in a hard to reach spot in terms of on the
bike massage or stretching.
I always assumed it was too bizarre to diagnose, but now...
Steve Hogg replies:
The placement you suggest doesn't sound like your hamstrings. More likely
it is your adductors. They tend to fire up on a bike if we are fighting for
on seat pelvic stability. Typically though, adductor pain on a bike is usually
felt higher up, so I may well be wrong. Do you stretch much?
If not that would be a start. Try ' Stretching and Flexibility' by Kit Laughlin
at any large bookshop as an accessible book for non stretchers.
It is probably not a bad idea to find a good structural health professional
[ physio, chiro or similar ] with knowledge of or interest in cycling and
have them examine you.
From what you have said, it sounds like there is something about the relationship
between your structural makeup and your bike that is not quite right. The
severity does not seem bad, but that this comes on when you are going hard
suggests that you are perhaps rocking a bit under high load. Try dropping
your seat 3 - 5 mm and let me know what happens.
I am wondering if you could expand on the topic of ankle flexibility. Your
last edition of Q&A had several topics relating to foot positioning, pedal stroke
efficiency, Achilles tendons etc. As a 42 year-old fitness rider putting in
120 mile weeks, I am aware of the three basic foot positions-neutral or flat,
heel down and toe down. But I've never come across any discussion regarding
the pros & cons of holding the ankle relatively stiff through the pedal stroke
versus allowing the feet to "paddle" through the stroke. Recognizing that we
all have our own preferences, is one technique more efficient than any other?
Will the large use of the calf muscles through paddling of the feet lead to
tendon injuries versus holding the ankle stiff? Is mixing of techniques (i.e.
spinning with more emphasis on the upstroke followed by mashing followed by
paddling) helpful or harmful through a ride by spreading the load to various
muscle groups? Your thoughts on this subject would be helpful.
Steve Hogg replies:
The best advice I can offer is to set your parameters of position by what
ever information you choose to use, and then forget about how you are pedalling
and just do what comes naturally to you. My reasoning for this is as follows:
There a wide variety of pedalling techniques out there, though most peoples'
technique fits into the category you have described as ' paddling', though
the degree varies. At either extreme there are the ' toe dippers' and the
' heel droppers' and again the degree to which this is exhibited varies
across a range of people. In answer to your first question, have a look
at ' Technique vs Position'
in Fitness Q&A for August 23 2004 for a discussion about varying
pedalling techniques and their relative efficiency.
In answer to your second question, it is unlikely. This is the way that
most people pedal and a large part of the calves are made up of postural
muscles full of slow twitch fibres that are designed for prolonged use.
The calves can be strained of course, as can any other muscle in the body,
but on a bike calf strains are usually the result of cleats that are too
far forward or [less commonly] too far back or to do with lack of structural
maintenance on the part of their owner.
Question 3; the job of the ankle on a bike, is to allow what I call 'flow'
at the bottom of the stroke. That is allow the motion of the legs to mate
with the circular motion of the crank. Holding the ankle in a fixed position
with foot dorsiflexed [heel down] will load the calves, while holding the
ankle in a fixed position with the foot plantarflexed [toe down] will tend
to unload the calves. The test, if you are experimenting is too see what
happens to you under high load, high heartrate conditions. The great majority
of our brains activity is devoted to controlling posture and movement. Most
of this is a level below conscious thought. Given a set of positional parameters
to work with, your body can usually be trusted to pedal in the most efficient
way within the constraints of its' own structure and degree of function.
Question 4. Mixing of techniques. On any ride other than a training ride
with a specific and narrow purpose, this is what is happening anyway. We
warm up with low to moderate loads at moderately high rpm. We hit a hill,
load goes up, rpm drops somewhat, pedalling technique changes to some degree
and so on. We see someone up ahead we want to catch and make an effort etc,
etc. If we pedalled in one gear at one speed over flat terrain we would
tend to have a single technique. In the real world this is next to impossible
for any length of time because of changes in terrain, wind direction, the
effort we wish to make at that time and so on. If you spin all the time
you will end up with good acceleration but no strength. If we ' mash' to
use your term all the time we end up with lots of strength but limited ability
to accelerate. We all need a foot in each camp to varying degrees.
I am 173 cm short and ride (road bicycle) on 170 mm cranks for last 12 months.
I do not experience any particular discomfort when spinning and my average cadence
is ~92 rpm. I have been recommended by a well recognized cycle-fit expert to
try riding on longer, 172.5 mm cranks. How do I know if my 170 mm or 172.5 mm
cranks are a better fit for me? What are the tell-tale signs of wrong length
cranks (too long? too short?)? is it a likely a pain experience or loss of performance?

This question is one that I've been giving some thought to lately, so I'll
share my thoughts and hope that some of the other coaches will jump in as
One way to determine if your cranks are too long is to struggle with your
bike fit as follows. If your seat is too high, you will find a dead-spot or
a jerky movement at the bottom of your stroke. If your seat is too low, you'll
find it difficult to pedal smoothly over the top of the stroke. Here's the
test: try pedaling with one foot and see if you can get smoothly over the
top. If not, raise the saddle a bit and try again. Repeat until you can pedal
fairly smoothly over the top. Now, if you had to raise the saddle so far that
you can no longer make power smoothly through the bottom of the stroke, your
cranks are too long. Of course if you practice to ankle and otherwise pedal
more smoothly or you make yourself more flexible, your current "too long"
cranks might turn out not to be too long at all.
This much I'm sure of. Now, I suspect but don't know for sure that the above
is pretty much equivalent to saying, "if you can pedal smoothly all around
the pedal stroke, your cranks are about the right length. I also suspect that
longer cranks are better for road racing until you get into trouble with ground
clearance or the cranks become too long by the test above. Again I hope one
of the other coaches will have some thoughts on this.
I get soreness in my left knee which I can control through regular stretching
but not cure, the right knee gives me no trouble at all. I have recently discovered
that dropping my heel as I pedal through the bottom of the stroke seems to mitigate
the onset of the problem. I also have a vague sense that I read somewhere that
dropping the heel may be better technique. I would appreciate any feedback on
why dropping the heel seems to be helping control the knee pain problem and
whether I should be trying to pedal that way anyway for better technique.
Scott Saifer replies:
When you drop your heel you are effectively increasing the leg extension
at all points of the pedal stroke. If this reduces your knee pain, there is
a good chance that raising the saddle a few mm (try five for a start) will
have the same effect without forcing you to adopt an unnatural (to you) pedaling
It is definitely not the case that all riders should try to drop their heels
as a way to improve technique.
Tony then asked:
Thanks very much for the prompt response - I have been thinking about raising
the seat so your suggestion is timely. I do also feel that I seem to get a bit
more power when I drop the heel though I have to think about it to maintain
form . Is dropping the heel the same thing as "ankling"?
Scott Saifer replies:
Dropping the heel is related to ankling, though they are not the same thing.
Dropping the heel over the top of the stroke allows to you start pushing harder
on the pedals earlier, which probably accounts for your sense of increased
power. You can keep doing that even if you raise the saddle.
Ankling consists of dropping the heel over the top of the stroke but then
extending the ankle during the down stroke so that the toe is down and the
heel up by the time you get to the bottom of the stroke. This allows an earlier
start to pulling up (what LeMond referred to as scraping mud off the bottom
of your boot) and also lets you get some small amount of power from your calf
muscle on the down stroke.
Completion of a pedal cycle with ankling means snapping pretty quickly from
toe-down to heel-down position near the 10-11 o'clock part of the stroke.
The amount of angular movement of the ankle and the amount of toe or heel
drop at the top and bottom of the stroke vary quite a bit, even among the
most successful cyclists. If you get the cleats and saddle adjusted well,
the ankling will usually take care of itself as long as you aren't deliberately
Sports drinks and dental health
On December 15, Jodie Newell asked about the
effects of sports drinks on dental health.
The following Friday I had an opportunity to discuss the article with my dentist
(as well as one can have a discussion with a dentist with her hands in your
She agreed with Ms Newell's dentist that frequently bathing one's teeth with
a sugar solution was not conducive to good dental health. But she did offer
one positive suggestion: the deleterious effects could be minimized by rinsing
one's mouth with water immediately after taking a drink of a sports drink. One
could swallow the water after swishing it around in the mouth.
Of course this approach calls for two water bottles: one with water and the
other with the sports drink.
Alternatively, I think that many of the same benefits could be obtained by
replacing the sports drink with an enery gel that would provide the carbohydrate,
minerals and protein and then drinking plain water for hydration and rinsing
out the mouth.
Knee problem update
Just wanted to give you some feedback on my injury [see Fitness Q&A for
November 1 2004 and October
6 2004]. I can confirm (and am happy to report) that I have got on top of
the problem, which was muscle tension in my left vastus medius which in turn
was stressing the muscle/tendon attachment onto the anterior side of the left
I have since been getting regular (twice a month at present) sports massages
on both legs with a little extra attention to the left vastus medius to keep
on top of things.
Since shortly after (approx 3-weeks) my last correspondence with you, the problem
has totally settled down & I can now train fully. I can't express enough to
other cyclist who are doing reasonable to large volumes of training, the importance
of stretching, flexibility (I brought the book you recommended to me - Stretching
& core strength matched also with regular (good) sports massage as part of a
regular training programme. I have come to realise over recent years that it's
just as important as time spent on the bike!

I am glad to hear that you are making headway with the injury. What you have
said in your last 2 sentences is absolutely on the money! I hope that others
may benefit from your experience BEFORE injury occurs.
