EFFECTS OF ACUTE AND CHRONIC REPEATED SPRINT INTERVENTIONS IN HYPOXIC EXPOSURE ON SOME PHYSIOLOGICAL PARAMETERS AND PERFORMANCE

In recent years, the repeated sprint ability (RSA) training has become more popular method as top-up training in team sports. This training method has also been applied in the hypoxic condition, named repeated sprint training in hypoxia (RSH). Even though there are some studies reporting that there is no effect on RSA performance in normobaric condition via RSH training, there are also some studies in the relevant literature which claim that this training method provides significant improvments on physiological, molecular and performance components. The results obtained from the studies are controversial and degrees of the chronic/acute hypoxic exposures (fraction of inspired oxygen: % 10.9-16.4) and test protocols (work-rest ratio, recovery duration between the sets and length of sprint) applied in the studies have variability. For this reason, the actual effectiveness of this training method is still questionable. It is important that practitioners understand the effectiveness of a training method. This review was prepared in order to summarize effects of acute and chronic hypoxic exposure on RSA performance
