In Part II of the study, the British Olympic track (sprint) squad cyclists demonstrated reductions in body fat index, % body fat and endomorphy (p greater than .05), increased Hb and PCV % (p greater than .05), and lowered HR at rest and in warm-up exercise (p greater than .05), but no change in leg power. Repeated interval sprints of short duration, maximal exercise on an "ergowheel" ergometer, at standardised power output, showed increased anaerobic index (p greater than .05) and acceleratory power (p greater than .01) but no change in sustained power output. Compared with "non-select" riders, a case study of the single "select" rider showed anthropometric differences in terms of lower height, weight, body fat index, % body fat and endomorphy, but enhanced mesomorphy and FEV %. Furthermore, the "select" rider demonstrated temporarily latent functional performance capabilities, in that increased anaerobic index, acceleratory and sustained power indices, as well as enhanced relative power output, were not identified until late in the competitive season.
在该研究的第二部分中，英国奥林匹克田径（短跑）队的自行车运动员身体脂肪指数、体脂百分比和内胚层体型降低（p大于0.05），血红蛋白和红细胞压积百分比升高（p大于0.05），静息和热身运动时心率降低（p大于0.05），但腿部力量没有变化。在标准化功率输出下，进行短时间重复间歇冲刺、在“测力计轮”测力计上进行最大运动，结果显示无氧指数增加（p大于0.05）和加速功率增加（p大于0.01），但持续功率输出没有变化。与“非选拔”骑手相比，对一名“选拔”骑手的案例研究表明，在身高、体重、身体脂肪指数、体脂百分比和内胚层体型方面存在人体测量学差异，但中胚层体型和第一秒用力呼气量有所增强。此外，“选拔”骑手表现出暂时潜在的功能表现能力，即无氧指数、加速和持续功率指数增加，以及相对功率输出增强，直到赛季后期才被发现。
