Abstract

Metabolic and cardiorespiratory responses of healthy adults were compared at similar incremental power outputs during a variable-resistance rowing exercise and a fixed-resistance cycle ergometer exercise. Repeated measurements of power (watts), VEBTPS, VO2 STPD, and HR were obtained on 60 men and 47 women ranging in age from 20 to 74 yr. Average maximal power output for the men was significantly higher (P less than 0.05) for cycling than rowing: 207 +/- 5.2 W vs 195 +/- 58 W (mean +/- SE). A similar difference was also observed for women favoring cycling: 135 +/- 4.1 W vs 126 +/- 4.9 W (mean +/- SE). VEBTPS, VO2 STPD, and HR were significantly higher at all power increments during the rowing graded exercise test (RGXT) when compared with the same exercise intensity during the cycle graded exercise test (CGXT). Consistent linearity was found between VEBTPS and VO2 STPD and between HR and VO2 STPD for both exercises. The linear relationship between VEBTPS and VO2 STPD for men during RGXT was r = 0.976, P less than 0.001, slope = 44.6 +/- 1.03, and for women during RGXT it was r = 0.990, P less than 0.001, slope = 19.6 +/- 0.36. The relationship between HR and VO2 STPD for men during rowing was r = 0.989, P less than 0.001, slope = 29.1 +/- 0.76, and for women during rowing it was r = 0.971, P less than 0.001, slope = 35.7 +/- 0.89. The linear relationship between VEBTPS and VO2 STPD for men during CGXT was r = 0.991, P less than 0.001, slope = 31.1 +/- 0.98, and for women it was r = 0.959, P less than 0.991, slope = 29.6 +/- 0.87. The relationship between HR and VO2 STPD for men during CGXT was r = 0.997, P less than 0.001, slope = 28.1 +/- 0.83, and for women it was r = 0.990, R less than 0.001, slope = 35.9 +/- 0.96. Results indicated that energy costs for rowing ergometry was significantly higher than cycle ergometry at all comparative power outputs including maximum levels. It was concluded that rowing ergometry could be an effective alternative activity for physical fitness and exercise rehabilitation programs.

摘要

在可变阻力划船运动和固定阻力自行车测力计运动中，对健康成年人在相似递增功率输出时的代谢和心肺反应进行了比较。对60名年龄在20至74岁之间的男性和47名女性重复测量了功率（瓦特）、标准体温压力下的每分通气量（VEBTPS）、标准温度压力干燥气体容积下的摄氧量（VO2 STPD）和心率（HR）。男性骑自行车的平均最大功率输出显著高于划船（P<0.05）：207±5.2瓦对195±58瓦（平均值±标准误）。女性也有类似差异，更倾向于骑自行车：135±4.1瓦对126±4.9瓦（平均值±标准误）。与自行车分级运动测试（CGXT）中相同运动强度相比，划船分级运动测试（RGXT）在所有功率增量时，VEBTPS、VO2 STPD和HR均显著更高。两种运动中，VEBTPS与VO2 STPD之间以及HR与VO2 STPD之间均发现了一致的线性关系。RGXT中男性VEBTPS与VO2 STPD之间的线性关系为r = 0.976，P<0.001，斜率 = 44.6±1.03，RGXT中女性为r = 0.990，P<0.001，斜率 = 19.6±0.36。划船时男性HR与VO2 STPD之间的关系为r = 0.989，P<0.001，斜率 = 29.1±0.76，划船时女性为r = 0.971，P<0.001，斜率 = 35.7±0.89。CGXT中男性VEBTPS与VO2 STPD之间的线性关系为r = 0.991，P<0.001，斜率 = 31.1±0.98，女性为r = 0.959，P<0.991，斜率 = 29.6±0.87。CGXT中男性HR与VO2 STPD之间的关系为r = 0.997，P<0.001，斜率 = 28.1±0.83，女性为r = 0.990，P<0.001，斜率 = 35.9±0.96。结果表明，在包括最大水平在内的所有比较功率输出时，划船测力计运动的能量消耗显著高于自行车测力计运动。得出的结论是，划船测力计运动可以成为健身和运动康复计划的一种有效替代活动。
