Influence of strength, endurance and concurrent training on the lipid profile and blood testosterone and cortisol response in young male wrestlers

Abstract

Background: There is little information regarding the effects of concurrent training (endurance and resistance training) on the fat profile, blood testosterone and cortisol response. The aim of the study was to investigate the effect of eight weeks of concurrent training on the fat profile, blood testosterone and cortisol response in young male wrestlers. Material/Methods: Twenty-four young male wrestlers voluntarily participated and were randomly assigned to three groups, namely: endurance training (ET, N=8), strength training (ST, N=8) and concurrent training (CT, N=8). The groups did their training programs three sessions per week. Results: The findings of this study showed that high-density lipoprotein cholesterol (HDL-C) decreased by 33.54% in the strength group (P=0.02). Total Testosterone (TT) experienced a decrease by 30.68% in the endurance group (P= 0.02) and by 41.55% in the concurrent group (P=0.02). Cortisol (cor) increased by 55.73% in the endurance (P=0.00) and by 41.55% in the concurrent (P=0.02) group, respectively. Testosterone-to-Cholesterol ratio (TT:Cor) decreased by 125.80% by and 78.12% in the endurance (P=0.00) and concurrent (0.04) groups, respectively. Conclusions: The results of this study showed that the decrease in HDL, an increasing trend in TT in the strength training group and also a decrease in TT and an improved lipids profile in the endurance and concurrent training groups can be a function of the training type.
