三天急性訓練對柔道選手肌肉能量路徑與體循環之效果

目的：本研究旨在探討3天急性訓練對肌肉能量路徑及體循環之效果，其次則探討Randori生物參數與攻擊次數之相關性。方法：受試者為8名健康成人柔道運動員。實驗之前後測為柔道專項測試（Uchi-Komi、Randori），前後測之間則進行3天急性訓練，內容包含短距離衝刺與Tabata、快速力量與協調訓練。結果：Uchi-Komi之恢復期最大乳酸堆積濃度於Pre-test為9.2 ± 1.9 mmol/L，Post-test則為7.1 ± 1.8 mmol/L，差異2.1 mmol/L（p＞.05）。乳酸堆積率（La_(rate)）則依序為0.8 ± 0.2 mmol/L．s、0.6 ± 0.2 mmol/L．s，差異0.2 mmol/L．s。Randori之最大乳酸堆積濃度與攻擊次數於Pre-test為15 ± 2.7 mmol/L以及11.3 ± 2.3次，而Post-test為13 ± 3.5 mmol/L與10.7 ± 2.2次。至於恢復期第1分鐘血氨濃度（NH_3-E1）於Post-test下降41.3 μmol//L（p＜.01）。Pre-test中Randori攻擊次數介於7-14次，而最大乳酸堆積濃度則介於11.4-20.09 mmol/L之間，兩項呈現負相關（r^2=.44）。最大乳酸堆積濃度與NH_3-E1的關係呈現正相關（r^2=.63）。結論：3天急性訓練對Uchi-Komi與Randori呈現改善趨勢，但是未達顯著。另一發現為Randori之最大乳酸堆積與血氨，兩者在無氧能量提供路徑呈現密切關係。在新規則要求更高的體能水準以及賽程時常變動的情況下，或許可藉由3天HIIT訓練作為短時間內改善體循環能力以及無氧代謝效率之應用。

Purpose: To investigate the effect of 3-day acute training on muscle energy metabolism and systemic circulation and to investigate the relation between the biological parameters of randori and the number of attacks made. Methods: Eight adult judo athletes participated in judo-specific tests (uchi-komi, randori) before and after a 3-day training period, which consisted of short distance sprinting, Tabata training, and speed strength, and coordination training. Results: The maximum lactate concentration during recovery from uchi-komi was 9.2 ± 1.9 mmol/L in the pretest and 7.1 ± 1.8 mmol/L in the posttest, representing a difference of 2.1 mmol/L (p ＞ .05). The rate of lactate production was 0.8 ± 0.2 mmol/L．s in the pretest and 0.6 ± 0.2 mmol/L．s in the posttest, with a difference of 0.2 mmol/L．s. The maximum lactate concentration and the number of attacks made during randori were 15 ± 2.7 mmol/L and 11.3 ± 2.3, respectively, in the pretest and 13 ± 3.5 mmol/L and 10.7 ± 2.2, respectively, in the posttest. Ammonia decreased by 41.3 μmol/L after the first minute of recovery in the posttest (p ＜ .01). In the pretest, the number of attacks made was 7-14 and the maximum lactate concentration was 11.4-20.09 mmol/L, demonstrating a negative correlation (r^2 = .44). Maximum lactate concentration correlated positively (r^2 = .63) with ammonia concentration. Conclusion: The 3-day acute training period lead to nonsignificantly improved performance in uchi-komi and randori. Maximum lactate and ammonia concentrations exhibited a close relationship during anaerobic metabolism. To meet higher physical demands due to new rules and the uncertainty of competitions, engaging in 3-day high-intensity interval training prior to competition may improve systemic circulation and energy metabolism.
