Preparation and Training Methods
Warm-up, cool-down and stretching
- 3 things to know
- Paper 2
Overview
The effects of a warm-up on muscles, oxygen delivery and joints, its three phases, the cool-down and lactate removal, DOMS, and static and ballistic stretching.
What you need to know
Answer each one before you reveal it.
How does a warm-up improve oxygen delivery to the working muscles?
Explain why a warm-up reduces the risk of muscle injury.
Questions from this subtopic
Each one with the model answer underneath.
- 1
How does a warm-up affect muscle temperature, and why does this help performance?
Model answer
A warm-up raises muscle temperature, which speeds up nerve impulse conduction and enzyme activity. Muscles can then contract faster and more forcefully.
- 2
How does a warm-up improve oxygen delivery to the working muscles?
Model answer
A warm-up causes vasodilation of the arterioles supplying the muscles, increasing blood flow. Higher muscle temperature also helps haemoglobin release oxygen more readily.
- 3
Explain why a warm-up reduces the risk of muscle injury.
Model answer
Warm muscles are more elastic and less viscous, so they stretch further before tearing. A gradual rise in intensity also prepares muscles for the sudden forces of competition.
- 4
What effect does a warm-up have on the synovial joints?
Model answer
Movement stimulates the release of synovial fluid, which becomes less viscous as it warms. The joints are then better lubricated and move through a fuller range.
- 5
Outline the three phases of a typical warm-up.
Model answer
A warm-up starts with a pulse raiser, such as jogging, to raise heart rate and body temperature. The second phase is stretching, and the third is sport-specific drills at rising intensity.
- 6
What is the physiological purpose of a cool-down?
Model answer
A cool-down is light activity that keeps heart rate and breathing elevated for a few minutes. The skeletal muscle pump then maintains venous return and prevents blood pooling.
