| Abstract |
| Objective: The increase in unhealthy behaviors such as smoking and physical inactivity are factors contributing to the incidence of cardiovascular diseases and mortality (1). This study aimed to investigate the effect of 12 weeks of exercise training at different intensities, including moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT), on physiological and anthropometric indicators, including maximum oxygen consumption, oxygen pulse (2), resting heart rate, and body fat percentage in sedentary young smokers aged 20 to 30 years. Methods: Thirty sedentary male students, smokers, aged 20 to 30 years, were randomly divided into three groups of 10, including the moderate-intensity continuous training (MICT) group, the high-intensity interval training (HIIT) group, and the control group. The training program was implemented in the MICT and HIIT groups for 12 weeks, three sessions per week. In order to compare the changes in physiological and anthropometric indices in the pre-test and post-test stages, paired t-tests were used, and one-way analysis of variance was used to compare the mean difference between the groups (3, 4). Results: The results showed that 12 weeks of MICT and HIIT training significantly reduced body mass index, resting heart rate, and body fat percentage in both intervention groups (P≥0.05). VO2max and pulse oxygen also increased significantly (P≥0.05). Also, in the between-group difference, HIIT training had a more significant improvement than MICT training. Conclusion: MICT and HIIT training produced significant improvements in aerobic capacity, pulse oxygen saturation, and body composition over 12 weeks, and decreased body mass index, body fat percentage, and resting heart rate. However, the HIIT group had greater effects on improving aerobic capacity and body composition than MICT, while the control group showed no significant change. These findings suggest that high-intensity HIIT training may be a more effective option for promoting physiological health and improving body composition. |
