Abstract: (19 Views)
Introduction: Firefighting is one of the most dangerous civilian jobs that require cardiovascular fitness, muscular strength, endurance, agility, and flexibility to successfully perform the task. Therefore, the aim of the present study was to investigate the effect of twelve weeks of simultaneous training on some physical fitness factors and body composition of firefighters' personnel in Bandar Imam Khomeini Special Economic Zone.
Materials and Methods: In this semi-experimental study, 20 volunteer employees were randomly divided into two experimental (n=10) and control (n=10) groups. The subjects in the experimental group underwent a 12-week protocol of simultaneous training, five sessions per week. Some indicators of physical fitness and body composition factors were evaluated before and after the 12-week protocol. For intra-group comparisons, the paired t-test and inter-group comparisons, the independent t-test was used and all statistical operations were performed at a significance level of 0.05 using SPSS version 23 software.
Results: The results showed that 12 weeks of concurrent training resulted in significant changes in agility test (P=0.045) and upper body strength (P=0.014) in the experimental group compared to the control group. However, the changes observed in weight (P=0.330), body mass index (P=0.588), waist-to-hip ratio (P=0.258), and aerobic power (P=0.068) in the experimental group compared to the control group were not statistically significant (P≥0.05).
Conclusion: According to the results of the present study, it seems that continuing simultaneous exercises in the long term can have more positive effects on the body composition and physical fitness of firefighters compared to performing only aerobic exercises.
