Endurance training results in increased mitochondrial and capillary density in muscle but has no effect on muscle glycolytic capacity. This is an example of what training principle?
A) overload
B) specificity
C) reversibility
D) none of the above

Question

Quizplus · Accepted Answer

The principle of specificity suggests that training adaptations are specific to the type of training performed. In this case, the endurance training resulted in increased mitochondrial and capillary density in muscle, which is a specific adaptation to aerobic exercise. However, there was no effect on muscle glycolytic capacity, which suggests that this type of training did not improve anaerobic capacity.
