The Warm-Up
A gentle warm-up should always precede strenuous activity. The purpose of this is:
- To stimulate the heart and lungs moderately and progressively.
- To increase blood flow.
- To increase body temperature gradually and increase the metabolism of skeletal muscle.
- To help prevent muscle and joint injury.
- To prepare psychologically for the effort to follow.
An effective warm-up consists of two parts:
1. General warm-up: This involves rhythmic movement of the entire body in order to increase circulation and body temperature. The time required will vary with the individual and the outside temperature. However, the commencement of sweating indicates that the body is ready for more vigorous activity.
2. Specific warm-up: This involves stretches and movements that will be specifically used in the activities to follow. Specific warm-up should aid in the prevention of muscle strain. The actual skill to be used later should be performed at medium speed. Numerous examples of specific warm-up can be seen prior to sporting events.
