摘要

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.
