Sports massage is a form of bodywork geared toward participants in athletics. It is used to help prevent injuries, prepare the body for athletic activity and maintain it in optimal condition, and help athletes recover from workouts and injuries. Sports massage has three basic forms: pre-event massage, post-event massage, and maintenance massage.
Muscle strains can be categorized into three grades, based on severity:
Grade 1: Mild damage to individual muscle fibers (less than 5% of fibers) that causes minimal loss of strength and motion.
Grade 2: More extensive damage with more muscle fibers involved. …
Grade 3: Complete rupture of a muscle or tendon.
Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A characteristic feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to sprinting.
