Saddle height and possible HR correlation
Recovering from broken hip
I am a 34 year old male, who has been riding on and off for about 20 years.
In general, I have been active and exercise frequently. When I ride with a heart
rate monitor, my heart rate is often about 20 beats faster than my other riding
companions. For the most part, I can keep up with or am faster than my riding
buddies. My maximum heart rate is about 201 beats/minute, which is also high
for my age range, and I can sustain an effort between 180-190 beats per minute
for 45 minutes or more. I had a recent physical examination with a general practitioner,
and everything is fine (bp 110/70, resting heart rate 55, hematocrit 46%, no
chest pain or discomfort). What might account for my higher heart rate? What
sorts of tests can I request to get a more accurate measure of my fitness level?
What type of doctor should I see for these types of tests? My main interest
is in maximizing my performance, and understanding the limitations of my natural
physiology (eg VO2 max, heart volume, etc.).Thank you.
Scott Saifer replies
You probably have smaller heart stroke volume than your riding buddies, that
is, you have smaller heart so it needs to beat faster to move the same amount
of blood. There are a variety of pathological conditions that decrease stroke
volume, but they generally decrease performance as well, so chances are you
simply have a smaller but healthy heart. If your training goes well, your
heart rate at any given power-output should decrease, but it will probably
always be higher than your ride companions' because your maximum is unusually
high. More interesting than comparing heart rates with your buddies is comparing
percentages of maximum or percentages of threshold heart rates. If you are
at a higher absolute heart rate but lower percentage of your capacity, you
are in good shape compared to them.
The information you are asking for about your physiological capacities and
limitations can be collected at a physiological testing center. You don't
need a physician. The testing you are asking about can be done at a well equipped
gym. Some hospitals also increase the utilization of their equipment by testing
healthy athletes as well as heart disease patients.
If you really want to know your heart volume, you need an echocardiogram
or other direct visualisation of your heart. For that you do need a physician
or at least a physician referral, though I'm not sure why an athlete would
be interested in that particular variable.
Following on from the response to the reply on thyroid function; I recently
have had total thyroidectomy and have also recorded a sudden fall in VO2max
score following the operation. The only medication I take now is thyroxin to
replace what the gland would normally produce. Is there a bearing on Vo2 max
and thyroxin levels or do I need to look for explanation in other areas.
It is strange to me that Vo2 max should fall significantly within two weeks
of normal training.
Kelby Bethards replies
How is the riding/VO2 max now? How soon after your surgery were you riding
and testing your VO2 max. The reason I ask, is that, although most people
feel generally ok a few weeks post-operatively, they aren't necessarily ready
to ride at a 90-100% level. Let me know how you are doing.
James Struthers then responded:
I have been monitoring resting heart rate, max heart rate and VO2 closely following
an operation. It seems that even the smallest adjustment in my thyroxin dose
has a marked effect on performance.
Metabolic rate, plus resting heart rate and max heart rate are all elevated,
and under exertion my performance decreases hugely as heart rate reaches max
levels very quickly. At one stage of over treatment an excess of two minutes
was added to my 10 mile TT time with heart rate much higher than normal for
this event. My VO2 max fell from the normal 65 to 54 within a three-week time
I then went through a dose adjustment and maintained a careful training regime
including interval training when I felt I could manage it. This time, after
a couple of weeks the thyroxin dose was too low. My resting heart rate fell
to about 34 bpm from 41 pre-operation. I felt lethargic and cold. During the
transition from hyperactivity to hypo activity my VO2 max went back from 54
up to 65 gradually over a couple of weeks and then started to fall again to
61. I struggled to reach target zones in interval training and felt light headed
when exerting myself heavily. I took part in a 10 mile TT, and although it was
an improvement from when dose levels were high I was still way off my personal
best. I am now on a dose in between what was discovered as too high and too
low. My VO2 max was tested yesterday at 65. Over the weekend I managed a reasonable
result at a mountain bike cross country race and am doing a 10 mile TT tonight.
I appreciate thyroxin takes time to establish itself to suitable dose but I
have been recording heart rates, body temp and VO2 max regularly against thyroxin
dose levels. There is definitely a trend. Too high and too low dose manifest
itself very quickly in terms of performance effects, perhaps even before a marked
change in thyroid function blood test results. Even to the extent I believe
I can predict with a reasonable degree of accuracy what my TSH, Free T4 and
T3 levels are going to be before I get the result (In terms of high, Ok and
I also notice that after taking my thyroxin in the morning and recording heart
rate at rest throughout the day there is a peek in HR about 4.5 hrs after taking
the dose this reading seems to be consistent and taken before lunch. I have
no doubt that thyroxin levels have a huge effect on performance and a small
adjustment can have a significant effect.
Kelby Bethards replies
Well, it certainly sounds like you have got it figured out. I fully believe
that most people that are "in tune" with their bodies and attentive can tell
when something isn't exactly right, even before the labs and us silly doctors
figure it out.
Since thyroxin is so intricate to our metabolism, that very small changes
can be felt when doing such high level efforts. While some people don't feel
such small changes, some most certainly do. It's kind of like adjusting the
fuel mix on a piece of junk car versus a race car...small changes to the race
car make a big performance difference. I had a patient that had only switched
generic brands of Thyroid medicine and we had to change her dose because they
were not exactly equivalent, but they shouldn't be too much different. But
that very small change was noticeable and she actually had physical signs.
So, some may disagree with me, but make sure you continue the same brand
of thyroid medicine. Not that one brand is better, but they aren't necessarily
In terms of your observation of the heart rate as related to the timing of
your dose, that does make very good sense...it would be nice if medications
people took would be "released" at a steady state, but for the most part they
aren't, they have a peak (and trough) depending on the dosage and the half-life
of the medicine.
Saddle height and possible HR correlation
I am a 31 year old Cat 3 racer, 5'-7" and 145 lbs. I have been racing for the
past 13 years- mountain, road, and 'cross.
I have a slightly "heel-up" pedal stroke, my saddle height has remained the
same for about three years now, and I've never experienced knee pain or any
other discomfort until just recently, when I had a small amount of pain in the
back of my left knee. I lowered my saddle about 4mm after about a week off the
bike, and my HR has seemingly dropped during seated tempo efforts by about 5-7
bpm. I've since raised my saddle back up 2mm, and my HR seems to have gone up
just slightly from the lower numbers.
As long as I've been wearing a heart rate monitor, I've always had a higher
heart rate than most of my similarly aged and physically similar teammates.
My current max HR is around 196, and three years ago it was around 204. My tempo
HR is between 165-170, and my field-test LT stays between 178-180. Sprinting
or intense climbing efforts are consistent with earlier numbers.
Could there be a physiological reason that my HR would correspond to saddle
Richmond, VA USA
Scott Saifer replies
Before I can answer your question, I need to ask you another one: are you
going the same speed, or making the same power if you have a way to measure
it, during your seated tempo efforts in the higher and lower positions?
If you are making the same or more power, you have stumbled on a way to substantially
increase efficiency. In that case I would recommend dropping the seat again,
at least the point you tested before. For the sake of completeness, I would
suggest also dropping it another couple of mm and testing again.
If you are not making the same power but making less power, your heart rate
is lower simply because you need less oxygen to make less power.
I am 42 yrs old, 5' 8'', 145 lbs, cat 1 road racer with knee and lower back
I recently had a bike fit using the Serrotta system, and was advised to position
the ball of my foot and front of my knee over the pedal axle as my glutes were
under-utilised. I also had IT band pain which was severe at times in my right
knee mainly, but also occasionally in the left. I tend to pronate, and when
standing my feet roll inwards. The knee pain was worse at the start of interval
training each year but decreased as I became accustomed to the new stress (not
the correct thing to do, I now know). I have now got custom orthotics and Le
Wedges with Speedplay Zero pedals/Nike Poggio3 or Shimano 214 shoes, and the
knee pain has disappeared.
Subsequent to my fitting I have read your input to Cyclingnews and feel more
comfortable with your suggestions on fit than the ball of foot/knee over pedal
axle idea. I was a typical cyclist who studied the pros and fitted a low, long
stem with the saddle back in the rails because it 'looked good' rather than
because it worked. The Serrotta fit was to the other extreme and I have now
ended up with something in the middle which I find comfortable and efficient.
The reasons given at the bike fit for moving the saddle forward were to better
utilise the glutes, but you state that the further forward you sit the more
work the quads do and the less work the glutes do. I have a short femur in relation
to my shin (the femur is still longer but only just). I take it from your answers
on Cyclingnews that this does not matter and my knee (the bump at the top of
the shin just below kneecap) should be behind the pedal axle, to a greater or
lesser extent, in all cases? Is there an optimum distance/range or is it, as
I suspect, down to individual preference and trial and error until you find
your most efficient position? I now have my knee about 20 to 25mm behind the
pedal axle with cleats positioned just behind the ball of my foot and find this
much better for pushing over top dead centre and pulling back through bottom
As far as the under-utilisation of the glutes is concerned I believe that my
average flexibility in the hamstrings but very flexible lower back was more
the cause. I tended to sit with an 'upright' pelvis and then curve forward from
the lower back with a stretched arm position to reach the bars. I am now sitting
as described above in relation to the pedals but with a straighter more neutral
back posture and a shorter stem resulting in less lower back pain. Attention
to posture off the bike is helping with this also. What is your opinion of some
of the pros who seem to ride with extremely rounded backs (Armstrong on his
TT bike springs to mind) - do they just have more accommodating physiques or
better physio back-up?
By the way, have you come to any conclusions on the Powercranks yet? I would
imagine that for someone with lower back/hip flexor issues there would have
to be a lot of maintenance stretching and posture work to be able to use them
(I didn't mention that I have reasonably tight hip flexors also!) Would a fixed
wheel bike be better this winter to encourage suppleness in the pedal stroke?
I do a lot of winter gym training involving leg raises in hanging and prone
positions. Will this help with strength in the hip flexors? A combination of
the gym work and the fixed wheel perhaps?
I hope you can find time to read and reply to this rather lengthy query.
Steve Hogg replies
Regarding pros with rounded backs - we all do what we can. Of the pros that
I have seen, there was the same structural and postural imperfections that
plague the rest of the cycling population, though they tended to be functional
but imperfect rather than dysfunctional but imperfect in a cycling sense.
They also have more relaxation time post ride and better access to health
professionals than the rest of us, and so they get by with issues that may
have more impact if experienced by a 40 year old club rider who has spent
a large part of his life behind a desk for 15 - 20 years.
I don't know much directly about Armstrong, but he seems to have problems
extending his back, looks stiff, pedals toe in, (more so on the right side)
and has a slight tendency to drop his right hip. Yet he is pretty effective
on a bike! He has a well documented 'big engine', good backup personnel to
give him the right advice and is of a professional mindset, meaning that he
has found out what he has to do to succeed on a bike and does exactly that.
The Armstrong hump seems less pronounced than it was a few years ago which
probably means he has been addressing his problems and getting the right advice
to address them.
Every time I see that hump in 'Big Tex's' back I am reminded of Tony Rominger,
and he was fairly handy too. I suspect that there is an element of self selection
with this too. If I come across 10 people with the same basic problem, they
will be affected to varying degrees. Sometimes this ranges from being totally
unaware there is a problem to being nearly crippled by it.
Regarding the Power Cranks - I think I am star crossed. Since I have had
them I have been off the bike either through injury or sickness. I plan to
get back on this week, get a few kilometres under my belt and start with the
Power Cranks this weekend.
I am looking at buying an exercise bike for home use and recently bought on
which is not very good, it is very jerky and not smooth. I am writng to receive
advice on what the best type of resistance is. The one I have is magnetic and
like I said not that good. I would be grateful if you could email me back explaing
which type would be better. Thankyou.
Scott Saifer replies
The fluid resistance trainers are the smoothest, quietest and have the most
natural feel, closest to riding a bike on the road.
However, even the magnetic resistance trainers should not feel jerky. You
either have a bad unit or don't have it set up correctly. The most common
cause of a jerky feeling resistance is not having enough contact pressure
between the tire and the trainer. If there is enough contact pressure, the
trainer presses into the tire and deflects it about 1/8" o or 3mm. Any less
and the tire slips against the trainer on acceleration or when riding hard.
Besides the uneven resistance feel, this also wears out the tires very quickly.
Recovering from broken hip
I'm aged 49, a keen cyclist and hiker. On June 26 this year, I broke my hip
(neck of femur) after crossing a pavement lip at an extreme angle. Since leaving
hospital after having a compression screw fitted, I have had one brief consultation
at the hospital where I was told that despite bone and scar appearing to heal
ok, "you'll never be what you were" and the scale of the loss is equivalent
to a "premiership footballer having to stop playing and go into management".
I'm due to attend hospital again in two months but I would be most grateful
if you could point me in the direction of any useful information regarding similar
injuries. Most of the sites I have found seem to be concerned with THR.
Scott Saifer replies
I don't have a lot of information for you, but do have an anecdote that may
help keep your spirits up. I have a client who won three medals in cycling
at the Police and Firefighters Games one summer at about your age. That winter
he broke the neck of his femur when he crashed on black ice while on a training
ride. He had several screws put in and couldn't ride for a couple of months.
When he began riding again, he could only do the lower half of a pedal circle
with the injured leg at first, so he did that again and again until he got
enough mobility to make full circles. We increased his training as he healed
and by five months after the accident he was pretty much back to normal, except
for a new respect for slippery pavement. The summer after the accident, he
again won the same three medals in cycling at the Police and Firefighters
Games. Good luck with your healing.
