Approaches to develop physical factors
The physical factor relates to the development of an area of fitness, an improvement in a skill or a development of a tactic.
Interval training
This involves alternating between periods of hard exercise and rest. For example, working for a set time/distance and then resting for a set time/distance. Interval training can be made harder by increasing the intensity or period of work, or by decreasing the rest period. It can improve speed, muscular endurance or power with a large work to rest ratio (\(1:4\)). It can also improve CRE with a shorter work to rest ratio (\(1:1\)) but over a longer period of time.
Gradual build-up
This is when skills are learned progressively. It breaks down complex or dangerous skills into easier steps/stages. Each part of the skill is introduced, practised and mastered before a new part is introduced. The complexity of the skill can therefore be gradually increased. The performer can progress up a stage when ready and can move back a stage at any time.
