Warm-up and Cool-Down Or Risk Injury or Fainting.

Warm-up and Cool-Down Or Risk Injury or Fainting.: "You must prepare your body before taking part in physical training, sports competition, or vigorous physical activity. A warm-up may help prevent injuries and maximize performance.
The warm-up increases the body's internal temperature and the heart rate so that more oxygen-rich blood can be pumped through the muscles. The chance of getting injured decreases when the heart, muscles, ligaments, and tendons are properly prepared for exertion and, vica versa the risk of injury increases unnecessarily when you do not go through a proper warm-up.
