Untrained adult males, aged 25 to 65+ years (N=110) were studied to assess the effects of aging on the exercise responses of middle-aged and older adults engaged in an endurance exercise training program. Subjects were divided into four age group categories and exercised at a training heart rate intensity of 75% Karvoner, for three to six months, until all participants could continuously log two miles. All subjects were involved in pre (T1) and post (T2) testing sessions to assess selected resting and exercising physiological data. A standard two-tailed t-test war, utilized as the method of statistical analysis. Significant increases (p4.05) were demonstrated in V02 max and VE max within all groups. Significant decreases (p4.05) were observed in HR max.. HR rest, body weight, percent body fat, systolic and diastolic blood pressure. It was concluded that exercise can improve various physiological variables studied, but that the effects of age do limit the ability of the older groups to attain the same level of fitness observed in the middle-aged groups.

The purpose of this study was to: 1) review the literature as it pertained to physical fitness for older adults and 2) develop an exercise and fitness guide to be used by older adults.Much of the literature dealing with: 1) cardiorespiratory endurance, 2) flexibility, 3) muscular strength and endurance, and 4) balance and coordination, suggests that given proper training and instruction, older adults can develop and maintain these areas of physical fitness well into advanced life.Older adults can develop and maintain their cardiorespiratory system by exercising at an intensity equal to 40% of their maximal heart rate. Walking is an activity in which that most older adults can participate and show improvement.Flexibility is a precursor for all movement. All movement depends on one's ability to bend and stretch. Regularity is the key to developing flexibility. Supple muscles and joints make many tasks easier and aid in the prevention of injury.Muscular strength and endurance are needed by older adults in many of the simple movements they face daily.Muscular strength and endurance can be developed and maintained through continued participation in regular physical activity.Balance and coordinated movement are important to older adults as they perform routine tasks encountered on a daily basis.Older adults can benefit physiologically, psychologically and socially from participation in appropriate regular physical activities and exercise programs. When older adults move their bodies physically, with regularity and purpose, they achieve a life of better health and well-being. / Center for Lifelong Education
