Abstract
This preliminary study examined the effects of wearing an elevation training mask® 2.0 (ETM) during high-intensity interval training (HIIT) on the aerobic capacity of young men. Twenty-six young men were recruited and randomly divided into an experimental group (EG, n = 13) and a control group (CG, n = 13). The former performed HIIT on a running platform while wearing an ETM, and the latter performed HIIT only. Before and after the intervention, the following parameters were measured: exercise performance indicator is a 3000-m running test; aerobic capacity indicators are maximal oxygen uptake (VO2max), ventilatory anaerobic threshold (VT), and running economy (RE); the physiological indicators are blood, pulmonary function, and cardiac function. After 6 weeks of intervention, there were significant differences (p < 0.05) between the time and time × group interaction for the 3000-m running time. There were no significant differences (p > 0.05) in VO2max between the time and time × group interaction. The VT and RE demonstrated significant differences (p < 0.05) between the time and time × group interaction. Among the physiological indicators, pulmonary and cardiac function differed significantly (p < 0.05) be-tween the time and time × group interaction. Blood parameters showed no significant differences (p > 0.05) between the time points and time × group interaction. These preliminary results suggest that using ETM in conjunction with HIIT for 6 weeks increased young men’s aerobic performance much more than conventional HIIT. This effect may be attributed to the significantly improved respiratory function and cardiac function caused by the combination of ETM with HIIT.
