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.
Drinking plenty of water throughout the day helps the lining of your large intestines absorb water, which helps you go to the bathroom more comfortably. Try to avoid eating for at least 2-3 hours before a run and avoid drinking 1 hour before a run. This gives your stomach time to digest before hitting the road. Keep a food log. For a full week keep track of what you eat/drink, how long before a run you eat/drink, and what symptoms occur during running. Over time you'll come to notice trends (i.e. if you eat a salad for lunch you'll be good to go for a long run pre-dinner) and come to learn what your body likes and dislikes.
