This page about healthy bones says "swimming does not involve weight-bearing benefits. But, it builds strong muscles which also helps to build strong bones."
Does anyone know an easy and inexpensive way to measure lung capacity? In an Anatomy and Physiology class I took about 30 years ago, all the students got their lung capacity measured. Mine was 3000ml and was the biggest in the class IIRC. I wonder what it is now.
I have huge lungs. When I get my PVT, the person giving to me always thinks somehting is wrong woth the machine. However, I also have asthma. I know other guys with large lungs (over 9 l) thye all have asthma.
A PFT is used to compare your lung volume and FEV1 to a statistical package of 1000s of data points. You could be a couch potato and get a 110% or a elite masters swimmer and never get to 100% (HELLO!).
My understanding is that lungs don;t "grow"--muscles grow. And our ability to process O2 can also be optimized through exercise.
Training (and a little rage) can also help in our ability to suffer horrible pain for minutes at a time.
