Question

The heart rate and ventilatory responses to a fixed submaximal work rate are lower (i.e., lower heart rate and lower minute ventilation) following an endurance training program. This training-induced adaptation is primarily due to changes in the ___________________.

Step-by-step explanation:

Physical training helps and induces adaptive changes in skeletal muscle. The change that is the most notable one is the increased concentrations of mitochondria and glycogen. The longer the training you do and the harder, the major changes in metabolism are presented.
