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.
