STRENGTH

 

Definition

Strength is the maximum force a muscle or group of muscles can exert at any one time. Strength can be further divided into Static Strength (muscles contract and hold one position), Dynamic Strength (muscles repeatedly apply force over a short period of time) and Explosive Strength or Power (muscles exert force in a short, fast burst).

 

Impact on Performance

Performing a scrum in Rugby would be an example of where Static Strength is required. Rugby Players are required to use Static Strength to stop the opposition from pushing the scrum and gaining an advantage. Dynamic Strength would be required when swimming short distances. Swimmers would require strong chest, arm and shoulder muscles when performing strokes like the freestyle, backstroke and breast stroke in order gain propulsion. Explosive Strength would be required for activities such as throwing a Javelin. Explosive Strength is used in single actions when maximum energy is needed.
