Effects of An Acute Exercise Up to Anaerobic Threshold on Serum Anabolic and Catabolic Factors in Trained and Sedentary Young Males

18953

Objective: The aim of the present study was to evaluate the effects of aerobic running exercise up to anaerobic threshold in trained (T) and sedentary (S) young males. Methods: The catabolic factors such as interleukin-6 (IL-6), oxidants and cortisol and the anabolic factors such as testosterone, growth hormone (GH) and insulin-like growth factor (IGF-I) were evaluated in blood serum of subjects. Results: It was found that running up to anaerobic threshold led to a significant increase in oxidants but not IL-6 in both groups. Indeed, oxidants returned to basal levels in 24 h in the T group. Cortisol decreased even below the basal levels 24 h after exercise in both groups. Anabolic hormones increased in both groups especially in the trained subjects after exercise. Conclusion Trained young people showed faster anabolic and catabolic adaptation to aerobic exercise comparing to age-matched sedentaries.
