Background and Aim: Aerobic power is a key determinant of the ability to perform repeated sprints at maximal speed and to accelerate the recovery process. This study investigated the effect of eight weeks of high-intensity interval training (HIIT) combined with iron supplementation on aerobic and anaerobic power in male military athletes.
Methods: In this quasi-experimental study, 48 male athletes (aged 25–35 years) from the armed forces in Khorramabad voluntarily participated and were randomly assigned to four matched groups: 1) training + iron supplementation, 2) training, 3) iron supplementation, and 4) control. The training protocol for the intervention groups consisted of eight weeks of HIIT (three 60-minute sessions per week at 90–95% of maximum heart rate). The supplementation protocol involved the consumption of 100 mg ferrous sulfate (two 50 mg tablets) before and after each training session for eight weeks. Aerobic power (Balke test) and anaerobic power (Sargent jump test) were measured 48 hours before and after the intervention. Data were analyzed using paired t-test, one-way ANOVA, and Tukey’s post-hoc test at a significance level of 0.05.
Results: Findings showed that all three intervention groups (training + supplementation, training only, and supplementation only) experienced a significant increase in both aerobic and anaerobic power compared to the control group (P=0.003). Although no significant difference was observed between the “training+ supplementation” and “training only” groups (P=0.26), the improvement in aerobic power in the “supplementation only” group was significantly lower than in the other two intervention groups (P=0.02).
Conclusion: Overall, while the combination of HIIT and iron supplementation improved both aerobic and anaerobic power, it did not show a significant advantage over training alone. Nevertheless, given the observed improvements across all intervention groups, high-intensity interval training is recommended for athletes aiming to enhance these physiological indices. |
