Regular moderate intensity physical activity and blood concentrations of endogenous anabolic hormones and thyroid hormones in aging men

Background: Physical activity has been reported to affect endocrine function in elderly men. Objective: To establish an association between regular moderate physical activity and endogenous anabolic hormone levels in healthy aging men. Participants: Twenty four middle-aged (57.4±4.7 years) and 24 el...

Zusammenfassung:	Background: Physical activity has been reported to affect endocrine function in elderly men. Objective: To establish an association between regular moderate physical activity and endogenous anabolic hormone levels in healthy aging men. Participants: Twenty four middle-aged (57.4±4.7 years) and 24 elderly (68.3±2.6 years) physically active men who in the past 10 years had been regularly bicycling during leisure time were compared with 24 middle-aged (57.9±4.0 years) and 24 elderly (67.2±1.7 years) sedentary men. Groups did not differ for body composition. Measurements: Serum dehydroepiandrosterone sulfate (DHEAS), insulin-like growth factor-I (IGF-1), free testosterone (FT), and thyroid hormone levels were assessed. Results: In general, elderly men had lower IGF-1 (P
