This study examined the relationship between 30-second anaerobic power and body composition by performance level in elite Judoists. During a 3-month period, 10 male Korean Judo national team athletes (NT), 26 male university varsity team athletes (VT), and 28 male junior varsity team athletes (JT) were assessed for 30-second anaerobic power and body composition at the Youngin University. Anaerobic power was measured using a 30-second Wingate test. Body composition was assessed via bioelectric impedance analysis in standardized conditions using BioSpace (Korean)-specific prediction formulas. All testing occurred at the beginning of the winter nonseason period but excluded a brief weight-loss period before the competition phase. Anaerobic power measures were significantly greater (p < 0.05) in NT and VT than in JT. Fat-free mass (FFM), muscle mass (MM), and total body water in JT were also greater than in VT and JT (p < 0.05). Muscle mass in VT was significantly lower than in NT (p < 0.05). Fat-free mass in NT was strongly correlated to mean and peak anaerobic power (r = 0.77, p = 0.009; r = 0.87, p < 0.001, respectively). Varsity team athletes also indicated a moderate association between FFM and peak and mean anaerobic power (r = 0.63, p < 0.001; r = 0.48, p = 0.013, respectively). However, relationship between FFM and anaerobic power was not statistically significantly correlated in JT (r = 0.14, p = 0.470; r = 0.23, p = 0.232, separately). In conclusion, our data indicated that anaerobic power is closely correlated with increase in FFM and MM and was different dependent among performance levels. Further research in the field is warranted to elucidate the Judo-specific relationship between FFM and performance.
本研究旨在探讨 30 秒无氧能力与精英柔道运动员运动水平相关的身体成分关系。在三个月的时间里，对 10 名韩国柔道国家队运动员（NT）、26 名大学生校队运动员（VT）和 28 名大学生校队运动员（JT）在 Youngin 大学进行 30 秒无氧能力和身体成分测试。无氧能力使用 30 秒 Wingate 测试进行测量。身体成分通过在标准化条件下使用 BioSpace（韩国）特定的预测公式进行生物电阻抗分析进行评估。所有测试均在冬季非赛季初期进行，但在比赛阶段之前的短暂减重期除外。NT 和 VT 的无氧能力测量值明显高于 JT（p<0.05）。JT 的去脂体重（FFM）、肌肉量（MM）和总身体水分也高于 VT 和 JT（p<0.05）。VT 的肌肉量明显低于 NT（p<0.05）。NT 的 FFM 与平均和峰值无氧能力呈强相关（r=0.77，p=0.009；r=0.87，p<0.001）。VT 运动员的 FFM 与峰值和平均无氧能力也呈中度相关（r=0.63，p<0.001；r=0.48，p=0.013）。然而，在 JT 中，FFM 和无氧能力之间的关系没有统计学意义（r=0.14，p=0.470；r=0.23，p=0.232）。总之，我们的数据表明，无氧能力与 FFM 和 MM 的增加密切相关，并且在运动水平上存在差异。需要进一步的研究来阐明柔道特定的 FFM 和表现之间的关系。
