Three hundred and sixty five male senior citizens were divided into experimental group(183 men)and control group(182 men).Exercise in experimental group was carried out with individual prescription for one year and the exercise in control group was in accordance to subjects' habitual interest. The results after 1 year showed that the anthropometric parameters between two groups revealed no significant difference, while the functional parameters were significantly improved in experimental group as compared with that in control group(p＜0.05 or 0.01).It was suggested that for senior citizens, exercise under prescription could significantly improve body function as compared with that without prescription.
