Plyometric
Intensity
Intensity is the effort involved in performing a given task. In weight lifting, intensity is controlled by the amount of weight lifted. In plyometrics, intensity is controlled by the type of exercise performed. Plyometric ranges from simple tasks to highly complex and stressful exercises. Starting out with skipping is much less stressful than alternate bounding. Double leg hops are less intense than single leg bounds.
The intensity of plyometric exercises can be increased by adding light weights in certain cases, by raising the platform height for depth jumps, or simply by arming at covering a greater distance in longitudinal jumps. Other writers have rated the intensity of various plyometric exercises from low to very intense. The exercises in this book are rated low to high. Any attempt to classify exercises by intensity is imperfect at best, but the guidelines provided here should help you in your program design.
