To examine the hypothesis that a lower level of physical activity influences the age-related decline in insulin-like growth factor-I (IGF-I), we measured serum concentrations in healthy nonobese younger and older men, characterized for maximal aerobic capacity (VO2 max) and energy expended in leisure time physical activity. To examine the independent influence of physical activity on IGF-I relative to other lifestyle variables, we also determined fat-free weight, percent body fat, body fat… CONTINUE READING

Our results suggest that multiple factors contribute to the age - related decline in IGF - I. Lower levels of IGF - I in aging men are related at least in part to diminished physical activity .
