Nitric Oxide and Oxidative Stress Changes at Depth in Breath-Hold Diving.

abstract：:Maximum aerobic power ([Formula: see text]) as an indicator of body fitness is today a very well-known concept not just for athletes but also for the layman. Unfortunately, the accurate measurement of that variable has remained a complex and exhaustive laboratory procedure, which makes it inaccessible to many active p...
