Final answer:
A sedentary individual that is beginning an aerobic exercise program typically experiences the greatest training-based improvements in VO2 max.
Step-by-step explanation:
A sedentary individual that is beginning an aerobic exercise program typically experiences the greatest training-based improvements in VO2 max. Aerobic exercise uses a relatively high percentage of slow-twitch muscle fibers that consume large amounts of oxygen, therefore increasing cardiovascular endurance. For example, cycling and brisk walking are examples of aerobic exercises that can help improve VO2 max.
