The more you ask of your body (muscles, bones, heart, lungs= stronger and fitter it becomes) Physical fitness: the body"s ability to respond or adapt to the demands and stress of physical effort. Health-related fitness: physical capabilities that contribute to health, including cardiorespiratory endurance, muscular strength, muscular endurance, flexibility and body composition- helps withstand physical challenges and protects us from diseases. Low: heart works hard, cannot sustain high-intensity physical activity. The amount of force a muscle can produce with a single maximum effort. Size of muscle cells, ability of nerves to activate muscle cells. Strong muscles needed to keep skeleton in proper alignment = greater muscle mass= higher rate of metabolism= healthy body weight= healthy age (e. g sarcopenia in elderly) Strength training maintains muscle mass, function, and balance - reduce osteoporosis.
