The Importance Of A General Warm-Up
The purpose of the warm-up is to prepare the body for physical activity. A warm-up
increases range of motion, puts the body in a state of readiness for vigorous
activity and enhances the performance of movement required for exercise. A thorough
warm-up reduces the risk of injury, especially when performed prior to repetitive
and/or resistance-based exercise.
Two types of warm-ups are typically used: general and specific. The purpose
of a general, circulatory warm-up is to
- Increase body and muscle temperature and blood flow to working muscles
- Facilitate the production of energy for exercise
- Increase oxygen delivery to muscles
- Improve the travel speed of nerve impulses
- Improve the speed and efficiency of muscle contractions
Gradually increase the load on the heart, which helps prevent abnormal cardiac
rhythm
A general warm-up results in mild elevation of the heart rate and ventilation
and perhaps light perspiration, but shouldn’t be fatiguing. As a rule,
the general warm-up should consist of moderately intense exercise lasting five
to 10 minutes. However, the more intense the planned workout, the longer the
general warm-up should be. Many people believe that warmed muscles, tendons
and connective tissue are more elastic and less likely to be injured during
physical activity, but very little scientific evidence supports that belief.
