Document Summary
Physiology and physiological adaptations to resistance training. Exercise prescription and resistance training principles: break, practical fitness assignment. Alleviate job / life stresses and perform better on the job (stressful court cases) Help prevent / control health conditions (obesity, t1&t2 diabetes, ms, post- stroke/brain injury, atrial fibrillation and other cardiovascular disorders*) Aging (mitigate sarcopenia / osteopenia /osteoporosis) *with extra caution. All physiological function will decay over time, however If remain active, the difference between sedentary and active behaviour may mean the difference between developing osteoporosis, improving / maintaining independence and performance through retirement or work. Muscle physiology & physiological adaptations to strength training. Each skeletal muscle is made up of many individual muscle fibres. These fibres are grouped together in bundles with connective tissue surrounding them to help transfer mechanical energy and allow for smooth contractions. It is the pulling of myosin on actin that causes contraction to occur.
