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.
Try these stretches to help your shin splints heal more quickly: Do a stair stretch. Stand on a step or a stair so that your toes hang over the edge. Point your toes downward, then stretch them toward the ceiling. Repeat 20 times, rest for a few seconds, then repeat 20 more times. Stretch by kneeling.
