Introduction: For alpine skiing, anaerobic power is used for producing the turn and dealing with bumps of surface (Kröll J et al., 2010). Aerobic power is used for continuing turns in entire runs, recovery between runs and competitions and keeping physical condition for a competition season (Neumayr G et al., 2003). To achieve success, alpine racers train both anaerobic and aerobic energy systems. However, the target values are required for the training. The aims of this study were to compare the anaerobic powers within world ranked, national ranked senior and junior alpine racers. Method: All subjects (world ranked (WR); n=2, national ranked senior (NS); n=10 and national ranked junior (NJ); n=9) were members of the Japanese national team in the tested year. Measured parameters were the following: height (cm), weight (kg), % body fat (%BF: %), fat free mass (FFM:, kg), isokinetic knee joint torque (IKKT: Nm/BW), vertical jump height (VJ: cm), counter movement jump height (CMJ: cm), squat jump height (SJ: cm), rebound jump height (RJ: cm) and repeated squat jump height (RSJ: cm). Furthermore, FIS point of slalom (SL) and giant slalom (GS) were obtained from the official FIS website. One-way ANOVA was used for comparisons between the results of senior and junior anaerobic power (p < .05) performed by SPSS Statistics 19. Due to the small number of subject from world ranked races, no statistical calculation was used for comparison. Result: All results of mean values from each group were following : IKKT of right leg extensor (Nm/BW); WR : 4.3, NS : 3.6 and NJ : 3.4, IKKT of right leg flexor (Nm/BW); WR : 2.0, NS : 1.9 and NJ : 1.8, VJ (cm); WR : 55.6, NS : 53.3 and NJ : 52.7, CMJ (cm); WR : 52.0, NS : 47.2, NJ : 45.4, SJ (cm); WR : 46.2, NS : 42.9, NJ : 41.3, RJ (cm); WR : 35.9, NS : 34.0 and NJ : 33.5 and RSJ (cm); WR : 45.6, NS : 44.0 and NJ : 41.2. There were no significant differences between anaerobic powers from the NS and NJ. Although not statistically different, all results of the WR were greater than NS and NJ races, and FIS point of SL from WR was smaller than NS and NJ. Discussion: Junior races have had already same anaerobic power to senior racers. Greater anaerobic power from the world ranked racers was observed compared to national ranked senior and junior races. Remarkably, fat free mass from world ranked racers was greater than the other skiers (WR : 71.3kg, NS : 65.9kg, NJ : 65.8kg). This difference would influence the relative anaerobic power tests results. Conclusions of this study were to achieve success in the world, senior and junior alpine racers should train anaerobic powers and on snow training.
