The aim of the current study was to examine the effects of 3-session repeated sprint training performed in a normobaric hypoxic condition with 48-hour rest intervals on sprint performance indices, arterial oxygen saturation (SpO2) and rating of perceived exertion (RPE) scores. Twenty-four moderately-trained males participated in this study voluntarily basis. This study was conducted on single-blind placebo-controlled design. Participants were divided into three groups as follows; normobaric hypoxia (3420 m; HYP), normobaric normoxia (162 m; PLA) and control group (CON). HYP and PLA groups subjected to 3 repeated sprint training session (4 set x 5 x 5 s sprints with 30 s recovery and 5 min rest between the sets) in normobaric hypoxia or normoxia condition. Pre- and pos-test were conducted 72 hours before and after the training intervention period. All the training and testing sessions performed in cycle ergometer. There were no detected significant time and condition interaction in the variables; relative peak power output (PPO), mean power output (MPO), percentage of sprint decrement score (Sdec%) and RPE observed in the scope of pre- and post-test.
