摘要

目的：本研究主要目的為採用不同訓練衝量 (training impulse, TRIMP) 法，探討室內與水上划船訓練量的差異。第二個目的為檢驗不同訓練衝量法間的相關性，並發展出新方法：血乳酸法 (blood lactate training impulse, BLa-TRIMP)，以監控划船運動的訓練量。方法：20名男子划船選手（年齡為17.1 ± 0.16歲、身高為176.5 ± 6.12公分、體重為76.0 ± 7.46公斤）自願參與本實驗。每位受試者在划船測功儀上進行漸增運動測驗，獲取最大心跳率、乳酸閾值 (lactate threshold, LT) 、乳酸激增點 (onset of blood lactate accumulation, OBLA) 、換氣閾值 (ventilatory threshold, VT) 以及呼吸代償點 (respiratory compensation point, RCP)，以計算訓練衝量。而後，所有受試者進行2,000公尺室內划船測驗 (indoor rowing test, IRT) 以及2,000公尺水上划船測驗 (outdoor rowing on water test, ORT) ，並計算訓練衝量。划船測驗全程監控心跳率，以及運動持續時間。兩種划船測驗在間隔至少48小時後，均進行第二次測驗，以評定各訓練衝量法的再測信度。結果：組內相關係數分析結果顯示，IRT及ORT具中等至高的再測信度 (ICC = .50 ~ .87, p < .05) 。IRT標準化的訓練衝量（除以運動持續時間）顯著高於ORT（IRT vs. ORT： Foster法，2.57 ± 0.26 vs. 2.31 ± 0.39 AU∙min-1, p < .05；Edwards法，4.34 ± 0.39 vs. 3.97 ± 0.67 AU∙min-1, p < .05；BLa-TRIMP，2.69 ± 0.20 vs. 2.44 ± 0.38 AU∙min-1, p < .05）。然而，未經標準化的訓練衝量則顯著低於ORT (IRT vs. ORT：基礎衝量法，25.00 ± 5.3 vs. 25.81 ± 6.28 AU, p < .05；RPE訓練衝量法，64.41 ± 5.36 vs. 69.90 ± 11.97 AU, p < .05)。IRT於高強度運動的持續時間顯著高於ORT。無論是IRT或ORT，BLa-TRIMP均與其餘訓練衝量法呈顯著相關 (r = .47 ~ .76, p < .05)。結論：2,000公尺室內划船的運動量與高強度運動時間比例高於水上划船，因此，未來對於設計划船運動/訓練的處方時，必須要注意兩者生理刺激的不同。除此之外，BLa-TRIMP具有良好信效度，可作為另一種評估划船運動量的方式。

Purpose: The purpose of this study was to investigate the differences on the training loads between indoor and outdoor rowing by using the different training impulse (TRIMP) methods. The second purpose was to examine the relationships among the different TRIMP, and to develop a new method, blood lactate training impulse (BLa-TRIMP), to monitor the training load on rowing exercises. Methods: Twenty male volunteer rowers (age, 17.10 ± 0.16 years; height, 176.5 ± 6.12 cm; weight, 76.0 ± 7.46 kg) participated in this study. Each subject performed the incremental exercise test on the rowing ergometer to obtain the maximal heart rates, lactate threshold, onset of blood lactate accumulation, ventilatory threshold and respiratory compensation point for calculating the TRIMP. And then, all subjects performed the 2,000 meters indoor rowing test (IRT) and 2,000 meters outdoor rowing on water test (ORT) to measure the TRIMP. The heart rates (HR) and exercise time were monitored during the both rowing tests. Both rowing tests were retested again at least 48 hours after the first rowing test, and the test-retest reliability of the TRIMP calculated from the different methods was also assessed. Results: The results of ICC (intraclass correlation coefficient) indicated that both IRT and ORT had a moderate to high test-retest reliability (ICC = .50~.87). The normalized TRIMP, divided by exercise duration, in the IRT were significantly higher than those in the ORT (IRT vs. ORT: Foster’s method, 2.57 ± 0.26 vs. 2.31 ± 0.39 AU∙min-1, p < .05; Edwards’s method, 4.34 ± 0.39 vs. 3.97 ± 0.67 AU∙min-1, p < .05; BLa-TRIMP, 2.69 ± 0.20 vs. 2.44 ± 0.38 AU∙min-1, p < .05). However, the TRIMP which could not be normalized were significantly lower than those in ORT (IRT vs. ORT: basic TRIMP, 25.00 ± 5.3 vs. 25.81 ± 6.28 AU; session RPE TRIMP, 64.41 ± 5.36 vs. 69.90 ± 11.97 AU, p < .05). The duration of high intensity during the IRT was significantly higher than that during the ORT. The BLa-TRIMP significantly correlated to the other TRIMP methods either in the IRT or in the ORT (r = 47 ~ 76, p < .05). Conclusion: The exercise load and duration of high intensity during the 2,000-m indoor rowing exercise could be higher than outdoor, thus, the program design of the rowing exercise/training prescription should concern about the different physiological stimulus in the future. In addition, the BLa-TRIMP might be a reliable and available method to measure the training load of rowing exercise.
