Warming up prior to any physical activity does a number of beneficial things, but primarily its main purpose is to prepare the body and mind for more strenous activity. One of the ways it achieves this is by helping to increase the body's core temperature, while also increasing the body's muscle temperature. By increasing muscle temperature you're helping to make the muscles loose. An effective warm-up also has the effect of increasing both your heart rate and your respiratory rate. This increases blood flow, which in turn increases the delivery of oxygen and nutrients to the working muscles. All this helps to prepare the muscles, tendons, and joints for more strenous activity.
Therefore, the benefits of warm-up exercises are the following:
1. The prevention of injury.
2. The improvement of performance.
3. The reduction of muscle stiffness.
4. Allows the heart rate get to a workable rate for beginning exercise.
5. Increased blood flow through active tissues as local vascular beds dilate,
increasing metabolism and muscle temperatures.
6. Facilitated oxygen utilization by warmed muscles because hemoglobin
releases oxygen more readily at higher muscle temperatures.
7. Increased speed of contraction and relaxation of warmed muscles.
8. Greater economy of movement because of lowered viscous resistance
within warmed muscles.
9. Facilitated nerve transmission and muscle metabolism at higher temperatures.
COLD JOINTS, TENDONS, AND MUSCLES CAN GET STRAINED BY SUDDEN MOVEMENT OR EXERTION.
WARMING UP BEFORE EXERCISE IS A GOOD WAY TO REDUCE THE RISK OF INJURY.
