Details on Plyometric Training in Physiotherapy: Definition, Types, Techniques, Benefits and PDF Notes
Definition:
Plyometric training is defined as a system of high-velocity resistance training
characterized by a rapid eccentric contraction during which the muscle elongates, immediately followed by a rapid reversal of movement with a resisted shortening contraction of the same muscle. Plyometric training also called stretch-shortening drills or stretch-strengthening drills.
Techniques:
The rapid eccentric loading phase is the stretch cycle, and the concentric phase is the shortening cycle. The period of time between the stretch and shortening cycles is known as the amortization phase. It is important that the amortization phase is kept very brief by a rapid reversal of movements to capitalize on the increased tension in the muscle.
Body weight or an external form of loading, such as elastic bands or tubing or a weighted ball, are possible sources of resistance.
Indications:
If patient is to return to high-demand occupational, recreational, or sport-related
activities
Effects of Plyometric Training:
1. Enhance physical performance
2. Increase in a muscle’s ability to resist stretch
3. Improve muscle’s dynamic restraint capabilities
4. Decreased incidence of lower extremity injury
