Abstract
Introduction: The aim of this study was to investigate the effect of a high-intensity interval training program on the physical fitness indicators of soldiers.
Methods: This study is a quasi-experimental study with a pre-test, post-test, and control and experimental groups. The statistical population is all military personnel. The statistical sample of the study was determined based on the inclusion criteria and using GPower software. The sample size was determined using GPower software (effect size 0.45, statistical power 0.95, and significance level 0.5) to be 30 people and they were divided into two control and experimental groups by simple randomization. The research tools were Sergeant's jump test and Cooper test. All statistical operations of the study were performed using SPSS version 25 software with a significance level of P<0.05.
Results: The results of the study showed that the difference in post-test scores between the experimental and control groups for the cardiorespiratory endurance and power variables was significant (p≥0.001).
Conclusion: These findings indicate that HIIT is effective in improving cardiorespiratory and muscular power.
