In science, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.The law of conservation of mechanical energy states that in an isolated system that is only subject to conservative forces the mechanical energy is constant.n science, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.
As with the standing shin stretch, the cross-over stretch is well-suited for pre- and post-running stretching. You can perform this stretch with or without shoes. Start standing with your feet together. Cross your right leg in front of your left leg and place the tops of your pointed right toes on the ground.
The stretch reflex prevents people from overextending their muscles. Protective response is what prevents muscles from being stretched too far. Before a workout, take time to gently and slowly stretch the muscles in order to help prevent any muscle damage.Runners who don't stretch adequately before a workout run the risk of muscle tears or other damage.Tapping the petellar tendon with a reflex hammer will trigger the knee jerk reflex.efore a workout, take time to gently and slowly stretch the muscles in order to help prevent any muscle damage.
