Why Warm-Up Before Exercising?
Warming up the body should always be done before any type of exercise. The entire human body needs at least 5 minutes in order to convert from the rest to the active mode. The cardiovascular system adapts to the strain by redistributing blood volume. Blood is diverted from the gastrointestinal tract to the muscles at work. The circulation in the active muscles increases; the metabolism is gradually ramped up and the muscles warm-up. The resilience of the cardiovascular system and the muscoskeletal system improves. Even the so called passive structures such as ligaments or joint capsules come into motion and prepare for the physical strain.
