Warming Up And Cooling Down
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.
A Warm-Up should include some running-in-place or slow jogging, stretching, and calisthenics. Get all the major muscle groups involved in the warm-up and pay particular attention to warming-up the parts of the body that will become subject to the most stress during the conditioning activity. After stretching all his major muscle groups, a major-league pitcher warms-up by throwing baseballs at increasing velocity. The last couple pitches are at game speed. Warming-up from the general to the specific like the major league pitcher is a good model to adapt and follow.
A Good Warm-Up should last five to seven minutes and should occur just before the sports activity or muscular endurance and strength part of the workout. The warm-up effect won’t last more than five minutes or so. If the delay before the intense physical activity begins exceeds five minutes then perform at least one or more mini-warm-ups before starting. After a proper warm-up, you have prepared your body for a more intense conditioning activity.
