|Introduction: High-intensity interval training is an effective training method for improving the aerobic and anaerobic power of athletes; however, the role of activity volume in high-intensity interval training efficiency is still unclear. Therefore, in the present study, the effects of low- and high-volume high-intensity interval training on aerobic power, anaerobic power, and lactate response in young soccer players were compared.|
Methods: In this study, 24 professional soccer players aged 20 to 22 who had no history of illness or taking supplements were chosen and randomly assigned to two groups of high-volume and low-volume high intensity interval training. High-intensity interval training was completed for eight weeks. Training sessions included 5 min of warm-up, the main training phase, and cooling down. The training phase in the first week included 8 repetitions of 15 s of running with maximum power and 15 s of rest. Every week, the number of repetitions was increased by two running test, and anaerobic power was evaluated using the Running-Based Anaerobic Sprint Test (RAST). Moreover, the level of blood lactate resulting from the RAST test was also measured using a lactometer.
Results: Blood lactate levels were reduced by 12% in the high-volume interval group and by 10% in the low-volume interval group in response to exercise. In addition, statistical analysis revealed that the blood lactate levels in response to exercise after 8 weeks of training were similar in both groups. On the other hand, , there was no significant difference in aerobic and anaerobic power between the high-volume and low-volume groups after eight weeks of interval training.
Conclusion: Overall, the findings of the present research indicated that intense interval training has a significant impact on improving aerobic performance, anaerobic markers, and lactate response in young soccer players, and there is no superiority between high- and low-volume training.
