The physiological profiles of 17 open grade (OG) and 13 reserve grade (RG) male surfboat rowers (SBR) aged 19-44 years were determined and compared. Parameters investigated included anthropometry, agility, isometric strength, flexibility, rowing ergometer performance (MT), peak VO2 and arterialised blood pH, lactate and bicarbonate. Means were compared using t-tests. Multiple regression analyses provided a number of models for the prediction of MT performance in SBR. The mean age, height, mass, and sum of eight skinfolds for SBR are: 26.2 (+/-5.9) years, 180.5 (+/-6.0) cm, 84.4 (+/-9.3) kg and 78.2 (+/-26.2) mm respectively. OG rowers were significantly different from RG for the parameters of ergometer performance (OG: 1360.2+/-42.9 m; RG: 1316.4+/-41.8 m), peak ventilation (OG: 174.2+/-17.2 L x min(-1); RG: 154.8+/-22.1 L x min(-1)), and post exercise blood pH levels (OG: 6.98+/-0.07; RG: 7.04+/-0.07). Performance on a rowing ergometer successfully discriminates between OG and RG rowers with the best predictors of ergometer performance in SBR being height, peak ventilation, and post exercise pH.
对17名19至44岁的公开级(OG)男子冲浪艇划手和13名后备级(RG)男子冲浪艇划手的生理特征进行了测定和比较。研究的参数包括人体测量学、敏捷性、等长力量、柔韧性、划船测力计性能(MT)、峰值VO2以及动脉化血液的pH值、乳酸和碳酸氢盐。采用t检验比较均值。多元回归分析提供了一些预测冲浪艇划手MT性能的模型。冲浪艇划手的平均年龄、身高、体重和八项皮褶厚度之和分别为:26.2(±5.9)岁、180.5(±6.0)厘米、84.4(±9.3)千克和78.2(±26.2)毫米。在测力计性能参数(OG:1360.2±42.9米;RG:1316.4±41.8米)、峰值通气量(OG:174.2±17.2升·分钟-1;RG:154.8±22.1升·分钟-1)和运动后血液pH值水平(OG:6.98±0.07;RG:7.04±0.07)方面,公开级划手与后备级划手存在显著差异。划船测力计上的表现能够成功区分公开级和后备级划手,冲浪艇划手中测力计性能的最佳预测指标是身高、峰值通气量和运动后pH值。
