This presentation discusses different types of muscle stretching. It introduces muscle stretching and defines it as flexing or stretching a muscle to improve elasticity and tone. There are four main types of stretching discussed: static, dynamic, ballistic, and PNF. Static stretching involves holding a stretched position for 30 seconds to 2 minutes. Dynamic stretching occurs during movement. Ballistic stretching uses bouncing motions and can cause injury. PNF stretching enhances range of motion through isometric contractions of opposing muscles. The benefits of stretching include relief from pain, increased flexibility and range of motion, better circulation, relaxation, and improved posture and energy.
