Backgrounds: In order to remain competitive, athletes and coaches are constantly looking for ways to enhance performance. The aim of this study was to investigate the effect of HIFT training and hypoxia mask on maximum oxygen consumption and respiratory efficiency of the players of Iran's men's national ice hockey team.
Method: In this semi-experimental study, 14 players of the Iranian national ice hockey team were divided into two HIFT and HIFT exercise with hypoxia mask groups, then both HIFT groups and HIFT exercise with hypoxia mask, performed HIFT training sessions with 30 seconds repetition and five sets for about an hour, three sessions a week for six weeks. Before and after the training session, anthropometry, body composition, maximum oxygen consumption (VO2max) and respiratory efficiency (vE/VCO2) were measured using in-body device and gas analyzer. The data were analyzed using the analysis of covariance test at the P<0.05.
Results: The results showed that HIFT exercise and HIFT exercise with hypoxia mask have an increasing effect on VO2max in elite ice hockey men, but there was no difference between the effect of HIFT exercise and HIFT exercise with hypoxia mask on VO2max (P=0.390). After the training, vE/VCO2 decreased in both groups, but there was no difference between the effect of HIFT training and hypoxia mask on vE/VCO2 in elite ice hockey men (P<0.05).
Conclusion: According to the results, it seems that HIFT and HIFT exercise with hypoxia mask may be able to help improve the performance of respiratory system in elite ice hockey men.
