The present study sought to examine the association between physical exercise as a lifestyle habit with anthropometric parameters and body composition and aging in men.Intensity of exercise was scored as metabolic equivalent-min/week (MET-min/week) from data of the questionnaire, while anthropometric parameters and body composition were carried out by standard measuring instruments and dual-energy X-ray absorptiometry scanner, respectively.Age was associated with decreases in bodyweight, height, total lean mass and bone mass, but an increase in fat mass. The negative association of lean mass with age was predominantly due to the negative association of lean masses in the legs and arm, while the positive association of fat mass with age was primarily due to the positive association of fat masses in the trunk and abdomen. Exercise of intensity greater than 1000 MET-min/week was significantly associated with higher lean and bone masses and lower fat mass. The increase in lean mass was predominantly in the legs, while the decreases in fat mass were in the trunk and abdomen.The study showed that the high intensity of physical exercise, equivalent to greater than 1000 MET-min/week, is required to effect beneficial changes in the body composition. Hence, results from the study support the importance of promoting a lifestyle habit of exercise of sufficient intensity in order to mitigate the increase risks of sarcopenia and obesity and their attendant ill effects on health in men as they age.

We have established a comprehensive diagnostic paradigm for the management of aging men which seeks to evaluate the various determinants of the aging process in five major health areas: cardio-health, bone health, sex health, general health and endocrine state. This paradigm appears to be useful for the management of the problem of aging in our local population. It could be used for the management of individuals as well as for population research. When combined with the establishment of evidence-based management modalities, it will provide a useful tool for the holistic management of aging in Asia.
