Abstract

Sprint interval training (SIT) is a concept that has been shown to enhance aerobic-anaerobic training adaptations and induce larger effects in hypoxia. The purpose of this study was to examine the effects of 4 weeks of SIT with 15 or 30 s in hypoxia on aerobic, anaerobic performance and critical power (CP). A total of 32 male team players were divided into four groups: SIT with 15 s at FiO 2 : 0.209 (15 N); FiO 2 : 0.135 (15 H); SIT with 30 s at FiO 2 : 0.209 (30 N); and FiO 2 : 0.135 (30 H). VO 2max did not significantly increase, however time-to-exhaustion (TTE) was found to be significantly longer in the post test compared to pre test ( p = 0.001) with no difference between groups ( p = 0.86). Mean power (MPw.kg) after repeated wingate tests was significantly higher compared to pre training in all groups ( p = 0.001) with no difference between groups ( p = 0.66). Similarly, CP was increased in all groups with 4 weeks of SIT ( p = 0.001) with no difference between groups ( p = 0.82). This study showed that 4 weeks of SIT with 15 and 30 s sprint bouts in normoxia or hypoxia did not increased VO 2max in trained athletes. However, anerobic performance and CP can be increased with 4 weeks of SIT both in normoxia or hypoxia with 15 or 30 s of sprint durations.
