Figure 6. Glycogen content in the vastus lateralis muscle as a function of cycling time at 75-80% of maximal oxygen uptake (VO2 max). Data points are mean values from 10 subjects. For each subject, exercise was performed repeatedly in periods of 15 min separated by 15 min rest periods. At the point of exhaustion and muscle fatigue, muscle glycogen stores were depleted.

A single reliably predictive laboratory measure of athletic performance does not yet exist. As a result, for practical application to athletes, findings in laboratory studies are extrapolated to competitive conditions. As extrapolation can be misleading, many studies employ only the most commonly used laboratory performance measures such as maximal oxygen uptake (V02 max), anaerobic power and capacity, endurance, time to exhaustion, perceived exertion, reaction time, etc.
