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.
I try to get at least one good long run in my new racing shoes before I wear them in an event. Typically, a 15 to 20 mile run. Marathoners never wear anything for the first time in an event ... not even a new shirt or a new pair of shorts.You are running a 5K though. try to get at least one good long run in my new racing shoes before I wear them in an event.
