The effect high-intensity strength and endurance training on cortisol, testosterone, and physical fitness taekwondo boys 15 to 20 years in Rasht

High intensity training change anthropometric and Biochemical parameters in athletes, so the aim of this study was to investigate the effect of a high intensity training course on BMI, cortisol and testosterone in taekwondo boys 15 to 20 years in Rasht. 

Material and Methods:

This quasi-experimental research, which was conducted with study population of 15 to 20-year-old boy’s taekwondo in Rasht. The subjects of this study were randomly divided into two groups.

The results of this study showed that six-weeks of high intensity training reduced the significantly the hormones cortisol (P = 0.001). Testosterone and anaerobic capacity significantly increased after exercise in both groups(P = 0.001). Comparisons between groups showed significant difference in anaerobic Capacity (P = 0.001).

High-intensity training in Taekwondo athlete probably have a positive effect on physical fitness factors, cortisol and testosterone hormones and improve the performance of this athletes.
