Introduction: Specifically, high intensive interval training (HIIT) may induce fatigue, which is a natural physiological response. Fatigue decreases dynamic balance ability and subsequently may negatively affect technical performance such as passing, shooting and dribling. These technical abilities are an important component of soccer players. Therefore the aim of this study was to investigate the effects of HIIT on single leg balance ability(SLBA) and alart time for return to the orign value in young athletes. Methods: Twenty one soccer players (12 males, 9 females, age = 21.76 ± 3.09 years; wt = 64.5 ± 9.8 kg; ht = 169.4 ± 7.18 cm) with no history of lower extremity injury participated in this study. The Biodex SD balance system was used to determined to non-dominant athletic single-leg stability(ASLS). Monark cycle ergometer was used for high intensity anaerobic exercies. Each subject performed four maximal effort cycling on a electronically braked cycle ergometer against a resistance equivalent to 0.075kg/kg body mass for 30 seconds with a three-minute rest intervals. Subjects were verbally encouraged to continue pedalling as fast as possible throughout the each test. After four maximal cycling, subsequently subjects performed ASLS test and then repeated same test with a five-minute passive rest period for 4 times. Results: The result of this study has indicated that, HIIT negatively effects SLBA. Furthermore SLBA turn to the baseline status after 5 minutes passive recovery duration. Discussion The main finding was that HIIT had negative significant impact on SLBA. The finding of this study has similarities with result of previous studies(Toshimitsu et al 2011; Wilkins et al. 2004). However balance recovery time in our study was faster than previous studies(Toshimitsu et al 2011, Susco et al. 2004),these differences may explained by the better dynamic balance on the dominant leg of soccer players(Rosario et al. 2011).
