19: kin 155: resistance training, physical activity, and aging. By 2030, # of people over 65 yrs will reach 70 million. Fastest growing segment is the 85+ yrs old segment. Aging is a complex process of many factors/variables. Overall: interaction of genetics, lifestyle, chronic disease. Flexibility: range of motion around a joint. Overall: natural course of aging is deconditioning. Exactly same as lack of physical activity. Aging is associated with decreased muscle mass/strength. Results in loss of function, increased fall risk. Leg and hip strength associated with decreased fall risk. Muscular weakness is associated with increased fatigue during adl"s. Makes basic activities more difficult--results in people being less likely to do activities. Health impairment decreases activity which results in even less function. 80% of older adults have at least 1 chronic disease. 50% of older adults have at least 2 chronic diseases. Death rate from disease has decreased due to medical interventions, but prevalence has increased.
