The muscles studied included the triceps brachii, pectoralis major, serratus anterior, and posterior deltoids. Advanced forms of plyometric push-ups could be problematic for individuals with back issues, given that an alternating plyometric push-up using a medicine ball has been shown to induce 6,224 N of compressive forces on the lumbar spine (6). CONCEPTS The PowerPoint PPT presentation: "BIOMECHANICS MECHANICS OF MOVEMENT" is the property of its rightful owner. Five important components in biomechanics are motion, force, momentum, levers and balance: Motion is the movement of the body or an object through space.
