Question

Quizplus · Accepted Answer

Shot-putters require short, intense bursts of energy to throw the shot, which requires the muscles to develop tension quickly. This means that the muscles must contract rapidly and generate force, which can lead to quick fatigue due to the buildup of lactic acid. While the other options may be true for some muscle types, the ability to generate tension quickly is the most important factor for shot-putters.
