Muscular power refers to the ability to generate maximum force over a short period of time. This is different from muscular strength (ability to generate maximum force overall) and muscular endurance (ability to sustain force over a longer period of time). Option A is incorrect as it describes muscular endurance, which is the ability to resist force over a longer period of time. Option B is incorrect as it only refers to the speed of contraction, which is not the defining factor of muscular power. Option D is incorrect as flexibility is the ability to move a joint through its full range of motion and is not related to muscular power. Therefore, option C best describes what muscular power is.
