Exercise 9

Given that lactate accumulation will adversely affect endurance, what test might be an indicator of maximal sustained running (swimming, cycling) speed?

Step 1 of 2

During athletic performances that last fewer than 20 min, 90 to 100% of the maximum aerobic power is used by athletes. Therefore, an athlete with highest VO2 max has a distinct advantage. During such events, lactate and H+ ions accumulate and adversely affect the performance of an individual. Accumulation of lactate and H+ ions leads to decreased ATP (adenosine triphosphate) production.
