The Effect of Sports Training on Physiological Functions of Wrestlers in the Post-Covid Era

Physical activity plays a protective role against diseases via reducing risk factors. The purpose of this research is to investigate the effect of two types of intense interval training (HIIT) and continuous aerobics on the pulmonary and cardiorespiratory functions of wrestlers who had recovered from corona disease.

This research was carried out using a semi-experimental method and a clinical trial in the form of pre-test and post-test. Accordingly, using Morgan's table, 45 participants were invited to a briefing session and then randomly divided into three experimental groups: experimental group 1 (continuous aerobic exercise 15 participants), experimental group 2 (intermittent high-intensity exercise 15 participants) and control group 3 (15 participants without training).

The present study showed significant difference in FVC, FEV1, PIF, systolic blood pressure, diastolic blood pressure, heart rate, time to fatigue, VO2max, and pressure perception scale between the three groups. Meanwhile, the differences between the three groups were not significant in the VC variable,. A significant difference was also observed between the average of the studied variables in group 1 and group 2 of the research in post-test compared to the pre-test, which was more remarkable in the intense interval training group compared to the continuous training.

Considering the effectiveness and improvement in physical fitness indicators of HIIT compared to continuous training, HIIT can be viewed as a cost-effective option for improving cardiorespiratory fitness and lung function. A health improvement strategy was employed.
