DuFour et al. (2006) conducted a study on the effects of training in normobaric hypoxia intermittently and how it affected two performance measures in elite endurance athletes. Eighteen subjects were used to test the effects of intermittent normobaric hypoxia training in comparison to standard training protocols in normoxic environments. The subjects were divided into two groups. Prior to training all subjects were tested for first and second ventilatory thresholds (in normoxic and hypoxic conditions respectively), VO2max in a normoxic environment and time to exhaustion in a normoxic environment. Subjects performed two high-intensity training sessions above their predetermined second ventilatory threshold per week for a six week training protocol. The first group (n=9) performed training in a normoxic environment (fraction of inspired oxygen = 20.9%) and the second group (n=9) performed the same protocol in a normobaric hypoxic (fraction of inspired oxygen = 14.5%) environment. Following the six week training protocol each group was tested again on their VO2max and time to exhaustion in normoxic environments. Only the group exposed to the hypoxic training showed improvement in VO2max and time to exhaustion. The normoxic group showed no such change. This study suggests that intermittent normobaric training in hypoxia has a positive impact on performance in endurance events. However, this study could be improved upon by extending the training period to exceed six weeks and…
