The clean and jerk motion in weightlifting, an aggressive rebound in basketball, and a sprinter's start are all considered power moves because they combine which factors effectively?

The clean and jerk motion in weightlifting, an aggressive rebound in basketball, and a sprinter's start are all prime examples of power moves because they effectively combine work and time. In these movements, power is defined as the ability to exert a maximal amount of force in the shortest possible time.

In the clean and jerk, the lifter has to lift a heavy barbell quickly and efficiently, requiring a significant amount of work to be done in a brief period. Similarly, during a rebound in basketball, players must exert force to propel themselves off the ground and return to be ready for the next play quickly. In sprinting, an explosive start is crucial because the sprinter needs to generate speed immediately after the race begins, demonstrating the critical relationship between the amount of work done (force exerted to start running) and the rapidity of that effort (time taken to reach peak speed).

This concept contrasts with the other options, which focus on either specific physical attributes or general athletic abilities, rather than the specific relationship of work done over time that defines power in these athletic scenarios.
