Background and purpose:

Cardiopulmonary function indicates the ability to transfer oxygen to active muscles for taekwondo athletes who perform high-intensity movements in a short period of time and is an important factor that directly affects sports performance. The aim of the present study was to investigate the effect of eight weeks of high-intensity functional training on the respiratory performance indicators of young female taekwondo fighters.

Methodology:

In this semi-experimental study, 16 female Taekwondo fighters between the ages of 17 and 27 were randomly selected and randomly assigned to two groups of high-intensity functional training (HIFT) and control. The HIFT training group participated in the training program for eight weeks and four sessions per week. Before and after the eight-week training period, anthropometric measurement, body composition and breath gas test (gas analyzer) of young female taekwondo fighters were performed. The data were analyzed by analysis of covariance test at a significance level of P<0.05.

Findings:

The results showed that time and the interaction of time and group had a significant effect on VO2max values in young female taekwondo fighters (P=0.001). Time had no significant effect on FVC and VE/VCO2 values (0.05). P>, but the interaction of time and group on FVC values in taekwondo girls.The young fighter had a significant effect (P = 0.001) and the interaction of time and group had no significant effect on the values of FEV1, PEF, FEF25-75 and VE/VO2 in Taekwondo girls of the young fighter (P > 0.05). Time had a significant effect on FEV1/FVC ratio (P=0.001), but the interaction of time and group did not have a significant effect on FEV1/FVC ratio in young female taekwondo fighters (P>0.05).

Conclusion:

According to the results of the research, probably HIFT exercises can be effective in improving the performance indicators of the respiratory system of young female taekwondo fighters. Therefore, performing HIFT exercises can be recommended as a safe and useful method to improve the lung function of women taekwondo athletes.
