Speed and Power Development in Sport

6.Muscle Strength and Power (specific to requirements)

5.Equipment

1.Elastic Energy/ Pre-Stretch

  1. Linking Linear and Angular Momentum
  1. Increase Distance

Ability to store elastic energy and prepare muscle for concentric contraction affected by:

Amount of stretch (magnitude)

Speed of stretch (relatively fast)

Pause time (minimal)

Approx. 20% extra benefit from pre-stretch to following concentric contribution

Increases distance and elastic recoil - increased power.

  1. Increase number of segments

Key mechanical differences between high and moderate speed strokes

High speed show: increase trunk rotational speed

Flattening the arc of the swing

Bat

Ball

Material properties

Material behaviour

Design

Upper limb power

Stabilize the scapula

Create an engine (specific muscle development)

Establish a base (lower limb power and core)
