Plyometrics: Jump Training for Power and Speed

Plyometric training - exercises that involve rapid, explosive muscle contractions using the stretch-shortening cycle - develops power qualities that are impossible to build through slow, controlled strength training alone. The stretch-shortening cycle refers to a muscle rapidly stretching (eccentric phase) then immediately contracting (concentric phase), like a spring being compressed then released. This produces greater force output than a standing start contraction.

The most effective plyometric exercises for general athletes: box jumps (jump onto a box, step down - the jump is the training stimulus, not the landing), broad jumps (horizontal jump for maximum distance), depth drops (step off a box and land softly - teaches shock absorption), single-leg hops (develop unilateral power and sports specificity), lateral bounds (develop side-to-side power important for most sports), and medicine ball throws (rotational and overhead power).

Plyometrics must be programmed carefully. They're best placed at the beginning of a session when the nervous system is fresh. Start with low-intensity, low-volume work (3-4 sets of 5-8 reps) and progress volume and intensity gradually. Rest fully between sets (2-3 minutes) - plyometric work is not circuit training; quality of explosive effort is the priority. Include plyometrics 1-2 times per week in your programme. The carryover to sport performance, gym strength, and everyday athleticism is significant, and most people notice improvements in quickness and reactivity within 4-6 weeks.
