Final answer:
Physical activity that results in muscular contraction and energy release involves both catabolic and anabolic processes, critical information for physical therapists who apply knowledge of mechanical energy and muscle function.
Therefore the correct answer is option is c) Physical activity
Step-by-step explanation:
The movement of the body which causes muscular contraction resulting in the release of energy is known as physical activity. During physical activity, glucose is broken down into simpler compounds in a process that is both catabolic and anabolic. The simpler compounds are then used to provide energy for muscle contraction. This is essential knowledge for physical therapists, who must understand how muscle contractions and energy release operate, including the underlying chemical reactions, as well as the role of mechanical energy in power movements of the body such as lifting.
Muscle contraction itself is a key function in exercises, which can be described by the type of muscle involved, such as skeletal muscle, and the effect on the muscle, whether it is hypertrophy (growth) or atrophy (shrinking).
