In a lot of training bibles, lactate threshold is a percentage of VO2max. Does this mean an athletic will experience muscles soreness before running out of breath?

I'm asking because I'm always out of breath before muscle soreness kicks in. I do see most rider gives up due to muscles soreness before running out of breath. Maybe some coaches can commend on it. Thanks

Heartbreak. Usually at a young age. It works better than any other pain for motivation.
Every other type of pain is secondary and, really, less damaging.

Human sensation for these things is highly unreliable. What we think is happening and what actually is happening can be two different things. A burning sensation is not nessecarily present at threshold or above. In labs this is why they monitor expired gases and take lactate readings.

Priceless, priceless, priceless.

Missed prend's reply (which is priceless) which makes my response a bit unclear as to whom I am replying. It's the OP. I think...

Look like there are no easy answer to my question. Maybe I should go see a doctor. I remember seeing some low numbers in my blood test.

What do you experience first then? Sore muscles or shortness of breath?

The doctor will not know either without any test and it's got to be a specialist.
What low numbers are you talking about. Hematocrit? The volume percentage of red blood cells.
The percentage is normally 40-45% in males.

After some time off the bike, I feel the lungs go first because my aerobic base is gone. Those first few weeks in the off season are hard on the lungs. After you ride consistently and build your aerobic capacity, your lungs will hang in there better and you'll start to feel your legs go. But it takes a developed aerobic engine to get to the point where your legs really give out. Until then, you'll huff and puff yourself to death.

I had some low MCV and MCH numbers. Not extremely low but below the limit for a normal person.

The scary part is my MCV gets lower year after year.

Hi,

Ask your doctor about Thalassemia also.

I am not sure about how this affect endurance sport, but Pete Sampras and Zidenine Zidane have this also.

From what I have read on this topic the answer lies in what type of training you are undertaking. If you are pushing hard gears at low revs then your muscles will be the first to complain. If you are spinning at a high cadence then your cardiovascular system will be the first to complain. I can't remember which book it came from but the quote is along the lines of...

'...two riders equally matched, the first pushing gears, the second spinning, as the pace goes up the first will fall behind due to muscle soreness the second due to shortness of breath.'
