Discuss the factors that affect VO2max.
What will be an ideal response?
VO2maxis affected by genetics, training, gender, age, and body composition. Although aerobic training can help people attain good or excellent cardiorespiratory fitness, only those with a strong genetic component are able to reach an "elite" level of aerobic capacity (60–80 mL/kg/min). Further, VO2maxis 15–30 percent higher in men. This is related to a greater hemoglobin content, lower body fat, and larger heart size in men (a larger heart pumps more blood and thus produces a greater stroke volume). VO2maxalso decreases by about 1 percent per year starting at age 25. This decrease, however, is only 0.5 percent per year in physically active individuals.
