Abstract
Background: Aging in the humans refers to a multidimensional process of physical, psychological, social changes, and deterioration of body functions. Exercise in advanced age still offer a lot of health benefits. While deterioration of body functions is inevitable, proper exercise slows down the aging process. The purpose of this study was to evaluate the effect of aerobic exercise training on immunosenescence in sedentary young elderly. Sixty elderly subjects participated in this study. The methods. The subjects divided randomly in to two equal groups, control group and study group and each group consisted of fifteen men and fifteen women. The age of the participants was between 60 to 75 years old. The study group had participated in aerobic exercise program with intensity of 60-85% of maximum heart rate for 1hour/day, 3 times/week for three months, while the control group was sedentary. The outcome measurements were NK number, NK activity and macrophages activity (Interleukin-6). The results of this study revealed that moderate intensity aerobic exercise training program produced a significant changes in NK cells numbers and activity and IL-6 level in comparison with the control group (p<0.05). In conclusion: Aerobic exercise program is effective and beneficial for NK cells percentage, activity, and also macrophages activity in the elderly subjects
