  2. What Is Electrical Muscle Stimulation? What: The practice of delivering electric impulses to different parts of the body, namely muscles. Galvani's experiment: • The muscles of the frog's leg twitched when presented with electricity. • The human brain is responsible for sending the body control signals, through the central nervous system (CNS).  • Muscles are not picky on where the electric signals come from. • They do not care whether it is the brain sending the signals or some other source - external like in Galvani's experiment. • If electrodes are placed in the correct spots on the body relative to a muscle and if the correct signal is applied, the muscles can respond. They are not limited to just twitching; if the right signal is applied, a clean muscle flexion or extension can occur.

  3. Bypass the CNS • Because your brain is not the primary controller, you are bypassing the central nervous system. • There are no psychological limits anymore; you are not held back by what you think your degrees of freedom are or how you move your muscles. • The signals from an external source can play with your muscles without constraints and by doing so your flexibility can be improved.  You can also potentially hurt yourself. • Electric muscle stimulation is used by doctors, therapists, physical trainers, and some other professionals. There are two main classes of usage: medical (or therapeutical) and recreational.

  4. Muscle Injuries A.Sore muscles-delayed-onset muscle soreness caused by microscopic injury to muscle tissue. B. Pulled Muscles-muscle tissue that has been overstretched, and usually occurs between joints, in areas such as the thigh (i.e., a groin pull).

  5. C. Muscle Cramps- an uncontrolled spasm or contraction of a muscle, Cramps can be caused by overworking a muscle or loss of electrolytes D. Tendonitis-injury to tendons which are smaller than most muscles and located at the high-stress joints. Damage causes inflammation, causing swelling and soreness in the joint. E. Shin splints-"medial tibial stress syndrome” encompasses a number of different types of injuries occurring in the lower leg.

  6. G. Ankle sprains-stretched or ruptured ligaments--tough, fibrous bands of tissue which extend from bone to bone, holding the joint together. H. Fatigue – what causes this? • Explain • Tennis Ball fatigue exercise • Compare to cardiac muscle
