Abstract

British Olympic road squad cyclists were monitored during the 1980 racing season to evaluate training for the Moscow Games. Riders demonstrated reductions in body fat index, % body fat and endomorphy (p greater than .05). Graded exercise, using a "Racermate" wind load simulator/racing cycle ergometer system, showed reduced cardiovascular demands to warm-up exercise, and increased cardiovascular index, VO2 maximum, aerobic/anaerobic threshold shifts during maximal exercise (NS), with no changes in gearing, equivalent road speed, absolute/relative power output and leg power. Compared with "non-select" riders demonstrated lower body fat index, % body fat and endomorphy (p greater than .05), higher Hb and PCV % (p greater than .05) and elevated neuroticism and extraversion (p greater than .05). Furthermore, "select" riders demonstrated lower HR and CV index during warm-up exercise (p greater than .05), and elevated CV index, VO2 maximum, aerobic/anerobic thresholds during maximal exercise (p greater than .05), resulting from higher gearing, equivalent road speed and absolute/relative power output (p greater than .05).

摘要

1980年赛车赛季期间，对英国奥运公路自行车队队员进行了监测，以评估为莫斯科奥运会所做的训练。车手们的身体脂肪指数、体脂百分比和内胚层体型均有所下降（p大于0.05）。使用“Racermate”风阻模拟器/赛车自行车测力计系统进行的分级运动显示，热身运动时心血管需求降低，最大运动时心血管指数、最大摄氧量、有氧/无氧阈值偏移增加（无显著差异），而传动比、等效道路速度、绝对/相对功率输出和腿部力量均无变化。与“非入选”车手相比，“入选”车手的身体脂肪指数、体脂百分比和内胚层体型更低（p大于0.05），血红蛋白和红细胞压积百分比更高（p大于0.05），神经质和外向性升高（p大于0.05）。此外，“入选”车手在热身运动时心率和心血管指数较低（p大于0.05），最大运动时心血管指数、最大摄氧量、有氧/无氧阈值升高（p大于0.05），这是由于更高的传动比、等效道路速度和绝对/相对功率输出所致（p大于0.05）。
