We related the rowing performance and the associated physiological parameters to the training load as estimated by a questionnaire addressing the mean habitual weekly energy expenditure (MHWEE) of twenty-one international and national level oarsmen. The questionnaire also addressed the energy expenditure during training (EET) sessions classified as low- (EE1), moderate- (EE2), and high-intensity (EE3). To evaluate the physiological capability of the oarsmen, they performed incremental exercise to determine their maximal oxygen uptake (V.O(2max)) and the V.O(2) relative to V.O(2max) corresponding to the 4 mmol.l(-1) blood lactate concentration (V.O(2)4 %). The mean work rate sustained during a 2000-m all-out event on a rowing ergometer was considered as the rowing performance. On average, the rowers spent 16.4 +/- 1.0 h.wk(-1) in training with 56 +/- 3 % of the time spent on the water. EET represented 43.5 +/- 1.7 % of MHWEE. Rowing performance and V.O(2max) were both related to MHWEE and EET. Also, rowing performance was related to EE1, EE2, and EE3. In contrast, V.O(2)4 % was not related to the estimated energy expenditures. These results suggest that rowing performance and V.O(2max) are related to training load while V.O(2)4 % was not in the present group of highly trained oarsmen.
我们将划船成绩及相关生理参数与训练负荷相关联，训练负荷通过一份问卷进行估算，该问卷涉及21名国际和国家级水平赛艇运动员的平均每周习惯性能量消耗（MHWEE）。问卷还涉及了分类为低强度（EE1）、中等强度（EE2）和高强度（EE3）的训练（EET）时段的能量消耗。为了评估赛艇运动员的生理能力，他们进行了递增运动以确定其最大摄氧量（V.O(2max)）以及相对于V.O(2max)的、对应于4 mmol.l(-1)血乳酸浓度的V.O(2)（V.O(2)4 %）。在划船测力计上进行的2000米全力比赛中持续的平均工作率被视为划船成绩。平均而言，赛艇运动员每周训练16.4 +/- 1.0小时，其中56 +/- 3 %的时间在水上训练。EET占MHWEE的43.5 +/- 1.7 %。划船成绩和V.O(2max)均与MHWEE和EET相关。此外，划船成绩与EE1、EE2和EE3相关。相比之下，V.O(2)4 %与估算的能量消耗无关。这些结果表明，在当前这群训练有素的赛艇运动员中，划船成绩和V.O(2max)与训练负荷相关，而V.O(2)4 %则不然。
