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).
