An alternative of specific training in hypoxia oriented to intermittent efforts: Intermittent Maximal Intensity Hypoxic Training (IMIHT

Abstract

In 2013 the "Maximum Intensity Interval Training in hypoxia" that combines high-intensity training with training in hypoxia exposure. This could be ideal for team sports where the demands of high intensity are common in the game. The aim is define a proposal EIMIH establishing a "dose" and analyze their effects on aerobic performance parameters, anaerobic and specific physical conditioning. Seventy-two participants were randomly divided into three groups: control, normoxia and hypoxia. They completed 8 sessions repeated sprints (10-s sprint, work-to-rest ratio 1:2) in hypoxia (FiO2 = 14.5%) or normoxia (FiO2 = 20.9%). Before, after and after 4 weeks of post-training aerobic parameters, anaerobic lactic and jump test were analyzed. Statistically significant differences were observed in intra group analysis in the group of hypoxia in the number of sprints performed (p <0.01), after post-training and after the 4 weeks of post-training (p <0.05) compared with the control group. No statistically differences were found in other parameters analyzed. In conclusion this new "dose" would be enough to improve repeated sprint ability, although it would not be enough to improve alactic anaerobic performance or lactic anaerobic power.
