The aim of this study was to evaluate instrumented tank rowing for its ability to measure objectively the individual performance components of power output and rowing skill in a sample of collegiate rowers. The measuring system utilized strain gauges and a potentiometer to measure force on the oar and its angular position at each sampling interval. Power outputs were calculated for 13 collegiate rowers tested individually during a 30-s bout of maximal work. Results from this 'tank test' were compared with power measurements from both Concept II (CII) and Stanford rowing ergometers and from a Wingate test, using similar 30-s bouts of maximal work. Significant differences (P < 0.05) were found between the tank test and all other modes of testing except the Wingate test for average power. These differences can probably be attributed to the different methods of power measurement and to the different skill-dependence associated with the tests. For each subject, peak power and average power per stroke were measured from the rowing tests. The CII and Stanford test data for all subjects were correlated with their tank test data. Similar correlations were made between tank data and the peak and mean power from the Wingate test. The strongest correlation was in peak power measurements with the Wingate test (r = 0.92, P = 0.0001). Instrumented tank rowing provided objective information on individual power output unique from rowing and cycling ergometry. Of the various tests, the tank test appeared to provide better and more complete power data specific to rowing. This method also provided objective data for interpreting various aspects of rowing skill, including oar handling, technical efficiency, consistency, stroke frequency, stroke recovery ratio and stroke length. Instrumented tank rowing has substantial potential as a coaching tool or as a self-training device for improving rowing ability.
本研究的目的是评估仪器化的水槽划船，以客观测量一组大学赛艇运动员的功率输出和划船技巧等个人表现组成部分。测量系统利用应变仪和电位计在每个采样间隔测量桨上的力及其角位置。在30秒的最大强度运动测试中，对13名大学赛艇运动员进行了单独测试，并计算了功率输出。将该“水槽测试”的结果与Concept II（CII）、斯坦福划船测力计以及温盖特测试（使用类似的30秒最大强度运动测试）的功率测量结果进行了比较。除温盖特测试的平均功率外，水槽测试与所有其他测试模式之间均存在显著差异（P < 0.05）。这些差异可能归因于功率测量方法的不同以及与测试相关的不同技能依赖性。对每个受试者，从划船测试中测量了峰值功率和每划平均功率。所有受试者的CII和斯坦福测试数据与他们的水槽测试数据相关。水槽测试数据与温盖特测试的峰值和平均功率之间也进行了类似的相关性分析。最强的相关性出现在温盖特测试的峰值功率测量中（r = 0.92，P = 0.0001）。仪器化的水槽划船提供了关于个人功率输出的客观信息，这与划船和自行车测力计不同。在各种测试中，水槽测试似乎能提供更优、更完整的特定于划船的功率数据。该方法还为解释划船技巧的各个方面提供了客观数据，包括桨的操控、技术效率、一致性、划频、划水恢复率和划水长度。仪器化的水槽划船作为一种教练工具或自我训练设备，在提高划船能力方面具有巨大潜力。
