Speed and Power Development in Sport
6.Muscle Strength and Power (specific to requirements)
Upper limb power
Stabilize the scapula
Create an engine (specific muscle development)
Establish a base (lower limb power and core)
5.Equipment
Bat
Material properties
Design
Ball
Material behaviour
1.Elastic Energy/ Pre-Stretch
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
Linking Linear and Angular Momentum
Key mechanical differences between high and moderate speed strokes
High speed show: increase trunk rotational speed
Flattening the arc of the swing
Increase Distance
Increases distance and elastic recoil - increased power.
Increase number of segments
