Document Summary

Kinesiology week 3 reading: physiologic responses and long-term adaptions to exercise. Movement requires activation and control of the musculoskeletal system; the cardiovascular and respiratory systems provide the ability to sustain this movement over extended periods. When the body engages in exercise training several times a week or more frequently, each of these physiologic systems undergoes spe(cid:272)ifi(cid:272) adaptatio(cid:374)s that i(cid:374)(cid:272)rease the (cid:271)od(cid:455)"s effi(cid:272)ie(cid:374)(cid:272)(cid:455) a(cid:374)d (cid:272)apa(cid:272)it(cid:455) The (cid:271)od(cid:455)"s ph(cid:455)siologi(cid:272) respo(cid:374)ses to aero(cid:271)i(cid:272) a(cid:374)d resista(cid:374)(cid:272)e e(cid:454)er(cid:272)ise o(cid:272)(cid:272)ur i(cid:374) the (cid:373)usculoskeletal, cardiovascular, respiratory, endocrine, and immune systems. The cardiovascular system, composed of the heart, blood vessels, and blood, responds predictably to the increased demands of exercise. With few exceptions, the cardiovascular response to exercise is directly proportional to the skeletal muscle oxygen demands for any given rate of work, and oxygen uptake increases linearly with increasing rates of work. Cardiac output (q) is the total volume of blood pumped by the left ventricle of the heart per minute.
