Objective: To observe and analyze the influence of aerobic exercise on the biological age of the elderly males with differenta- ging degrees.

Methods: A total of 100 retired elderly males were enrolled in this study. All the elderly males performed theincremental load aerobic exerciseusingcycle ergometer. The physiological parameters of the candidatessuch as the biological age, body shape, cardio- vascular and pulmonary function were measured before and after the exercise. Based on the gap between the biological age and the actual age, the 100 cases of elderly males were divided into pro-senescence group (50 cases) and delaying senescence group (50 cases) for comparative study.

Results: Before the aerobic exercise was carried out, the elderly males possessed larger biological age as compared to their actualage, however, the difference was not statistically significant (P> 0.05). The elderly males who completed the aerobic exercise showed smaller biological age than the actual age, with P<0.05. Moreover, the pro-senescence group had a larger biological age than their actual age before they performedaerobic exercise. However, after the aerobic exercise was executed, the result indicates thattheir biological age was close to their actual age butwas lower than that of their actual age before accomplishing the aerobi- cexercise was accomplished (P <0.05). On the other hand, the biological age of delaying senescence group wassmaller than the actual age. In comparison to the biological age of candidates before experienced the aerobic exercise, the biological age of the can- didates after aerobic exercise was lower. After aerobic exercise,when P>0.05, the pro-senescence group exhibitedsmaller waist and larger waist-to-hip ratio; as P <0.05, the pro-senescence group showeda smaller skinfold thickness of the upper arm and their phy- siological function index changed significantly. Furthermore, with P <0.05,the systolic blood pressure and diastolic blood pressure among the cardiovascular and pulmonary function of the two groups decreased, and at the same time, the vital capacity increased,.

Conclusion: Aerobic exercise can exert positive impact on the biological age, physiological function and body shape of the elderly males with different aging degree, and delay their senescence.
