Plyometric exercises are defined as explosive movements that aim to develop power and speed. These types of exercises typically involve rapid stretching followed by a forceful contraction of the muscles. This process enhances the body's ability to exert maximum force in short intervals of time, which is crucial for improving athletic performance in various sports. Examples of plyometric exercises include jump squats, box jumps, and burpees, all of which require quick and explosive movements that engage multiple muscle groups.

In contrast, the other options do not accurately represent plyometric exercises. Low-impact resistance exercises focus more on building strength without the explosive element; stretching routines are designed for improving flexibility and do not involve the rapid, powerful movements characteristic of plyometrics; and long-distance running techniques primarily emphasize endurance rather than the explosive power that plyometrics develop. This distinction ensures that plyometric exercises serve a unique purpose in a comprehensive fitness routine.
