2. WHAT IS PLYOMETRIC EXERCISE? The development of the term is plyo- comes from the Greek word, which means “to increase and metric literally means "to measure." The development of the term is plyo- comes from the Greek word, which means “to increase and metric literally means "to measure."

3. Plyometrics exercises is a form of training that attempts to combine speed of movement with strength Plyometrics exercises is a form of training that attempts to combine speed of movement with strength

4. How Plyometric Exercises Work How Plyometric Exercises Work A muscle that is stretched before a concentric contraction, will contract more forcefully and more rapidly. But why does this occur?

7. The Stretch-Shortening Cycle

8. Goals of plyometric training Effective plyometric training relies more on the rate of stretch than on the length of stretch. Effective plyometric training relies more on the rate of stretch than on the length of stretch. Emphasis should center on the reduction of the amortization phase.

9. PROGRAM DEVELOPMENT Sport specific activities should be analyzed and broken down into basic movement patterns. These specific movement patterns should then be stressed in a gradual fashion, based upon individual tolerance to these activities.

11. PLYOMETRIC PROGRAM DESIGN The plyometric training program can be manipulated through training variables: i.e., direction of body movement, weight of the athlete, speed of the execution, external load, intensity, volume, frequency, training age. and recovery.
