Exercise
A warm up generally consists of a gradual
increase in intensity in physical activity (a “pulse raiser”), joint mobility exercise, and stretching,
followed by the activity. Warming up brings the body to a condition at which it safely responds to
nerve signals for quick and efficient action.
For example, before running or playing an intensive sport, the athlete might slowly jog to warm
their muscles and increase their heart rate. It is important that warm ups be specific to the activity,
so that the muscles to be used are activated. The risks and
benefits of combining
stretching with warming up are disputable,
although it is generally
believed that warming up prepares the athlete both mentally and physically. In a meta-study of 32
high quality studies, about 4/5 ths of the studies showed improvements in performance.
