Final answer:
The influence of nature and nurture on VO2 max.
Step-by-step explanation:
The question is about the influence of nature and nurture on VO2 max. VO2 max, also known as maximal oxygen uptake, is a measure of the maximum amount of oxygen that an individual can utilize during intense exercise. While genetics do play a role in determining an individual's VO2 max potential, the impact of training and environmental factors is significant in shaping the individual's actual VO2 max.
Through regular exercise and specific training, individuals can increase their VO2 max. This means that nurture, or training, has a significant influence on VO2 max. Training improves the efficiency of the cardiovascular system, increases the number and function of mitochondria (the energy-producing units of cells), and enhances the transport and utilization of oxygen.
Therefore, while genetics set the upper limit for VO2 max, training and environmental factors have a considerable influence on an individual's actual VO2 max level.
