Aims: Identifying and using effective exercise methods is essential to people's health, especially military personnel. Therefore, this study aimed to compare the effect of eight weeks of CrossFit and high-intensity interval training with physical fitness training on health and functional factors (arterial oxygen saturation, cardiorespiratory fitness, muscular endurance, speed, and agility) of military students.
Materials and Methods: This research was conducted experimentally with a pre-test and post-test design among students in their second year of Afsari University in Iran in 2021. Forty volunteer students participated in the study selected by available sampling. The samples were randomly divided into four groups as CrossFit training (10 people), high-intensity interval training (10 people), combined CrossFit and high-intensity interval training (10 people), and physical fitness training (10 people). Each training group participated in an eight-week training program that included four sessions per week. In order to estimate the factors of saturation of peripheral oxygen percentage (SPO2), maximum oxygen consumption (VO2max), muscle endurance, speed and agility, pulse oximeter, Queen college step test, sit-up test, 45-meter speed, and agility test were used respectively. SPSS 20 software was used to analyze and perform statistical tests at a significance level of 0.05.
Findings: The in-group results showed that the maximum oxygen consumption, percentage of blood oxygen saturation, muscle endurance, agility and speed in the HIIT, CrossFit and HIIT+ CrossFit groups were significantly different compared to the pre-test as HIIT+ CrossFit, CrossFit and HIIT group were respectively the most effective compared to physical fitness training (p<0.05). Also, the comparison between groups showed that the maximum oxygen consumption in the groups of physical fitness with CrossFit and physical fitness with HIIT+ CrossFit had a significant difference (p<0.001). Blood oxygen saturation percentage (p=0.006), speed (p=0.024), agility (p=0.001) and muscle endurance (p=0.002) were significantly different between physical fitness and HIIT+ CrossFit groups.
Conclusion: In general, according to the results of the present study, CrossFit and HIIT exercises probably have a better effect on the health factors and performance of military students than common physical fitness training.
