Warming of body raises temperature from 1 degree to 2 degree F, in order to reduce the viscosity of muscle to have better mobility, range of motion, stretch reflexes for better power in muscle and cardiorespiratory adjustment of supply of blood, oxygen & glucose as per demands of effort during playing.
The warm-up exercises include rolling, stretching, flexing and agilitic movements to develop coordinated complex movements of neuromuscular function (mechanism of reciprocal stimulation and inhibition).
This thereby, prevents incidence of injury of musculo-skeletal structures, improve efficiency of muscular effort (ergonomics). Lack of adequate warming up before playing develops bodily and psychological problems.
