Exercise trained individuals have a lower oxygen deficit;this may be due to
A)increased pulmonary lung capacity.
B)increased levels of glycolytic enzymes in the trained muscle.
C)a greater involvement of the ATP-CP energy system at the onset of exercise.
D)having a better developed aerobic bioenergetic capacity.

Question

Quizplus · Accepted Answer

A lower oxygen deficit suggests that the aerobic system is able to meet the energy demands of exercise more quickly, reducing the need for anaerobic energy production. This indicates that the individual has a better developed aerobic bioenergetic capacity, which is consistent with choice D. Choices A, B, and C do not explain this phenomenon.
