ABSTRACT

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
