[Purpose] Maximum anaerobic power is a measurement and evaluation method that is widely used in many competitive events using a bicycle ergometer. This study focused on the optimal load value that yields the maximum anaerobic power value, and investigated the loading method to detect the optimal load value. [Method] Thirty-two male alpine skiers were used as subjects. Subjects measured their maximum anaerobic power using two different loading methods. Using a personal computer built into the widely used Power Max VII (manufactured by Konami), the subjects performed a 10-second full-force drive exercise and two arbitrary load values using the conventional loading method. The test was performed by calculating the maximum value after a minute of rest. On the other hand, this research devised a unique loading method and carried out full-power driving for 10 seconds at seven levels of load values: 3%, 5%, 7.5%, 9%, 11%, 13%, and 15% of body weight. Exercises were carried out. In addition, we examined the optimal load value obtained by measuring maximum anaerobic power by taking a 4-minute rest between all-out exercises. [Results and Discussion] In measuring maximum anaerobic power using a bicycle ergometer, we compared two types of loading protocols: the conventional three-step loading protocol and the loading protocol devised in this study. As a result, the maximum anaerobic power value was 16.1 ± 1.7 watt/kg with the conventional loading protocol, and 13.4 ± 2.2 watt/kg with the loading protocol devised in this study, which was a significant difference between the two. was observed (p<0.05). On the other hand, when comparing the optimal load value obtained when maximal anaerobic power is exerted, the conventional loading protocol is 8.7 ± 1.1 kp, whereas the optimal load value with the loading protocol devised in this study is 9.3 kp. ±1.7 kp, which was significantly higher than that of the conventional type (p<0.05). From the above, it became clear that the loading method devised in this study showed higher maximum anaerobic power and optimal load values than the conventional loading method.
