What is the primary risk associated with ballistic stretching?

Ballistic stretching involves rapid and bouncing movements to push a muscle beyond its typical range of motion, which can create momentum that leads to overstretching and, consequently, potential injuries. This method often lacks the controlled environment that other types of stretching provide, increasing the likelihood of straining muscles or damaging soft tissues. The abrupt force applied during ballistic stretching can stress the muscle-tendon unit without allowing adequate time for the muscle fibers to adapt, which can make injuries more likely.

In contrast, other options present advantages rather than risks. While improvements in flexibility can occur with various forms of stretching, the speed at which one may see progress is not the central focus when considering the risks associated with stretching techniques. Likewise, while efficiency is important, the method chosen should prioritize safety over time-saving. Engaging more muscle fibers is a benefit seen in various types of exercise but does not directly relate to the primary risks of ballistic stretching. Understanding these dynamics helps ensure that stretching methods employed during fitness training are both effective and safe.
