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.
To ease the pain and reduce inflammation, ice your shins immediately after running. Use either a store-bought cold pack or simply freeze a wet towel before going out on a run. Whatever you use, wrap the ice pack around your leg and keep it on for 10 or 15 minutes, keeping your foot elevated all the while.
