摘要：A video race analysis was conducted at the Sydney 2000 Olympic and Paralympic Games in the 100-m freestyle event for three visually impaired classes (S11, S12, & S13) in both males and females. Supplementary information was available in small sub-samples for some physiological and biomechanical parameters. All visually impaired swimmers used race speed patterns similar to Olympic swimmers. These swimmers did not spend more race time starting or turning. The S11 class with greatest impairment swam slowest and was least competitive. Classes S12 and S13 did not differ in this respect. The race patterns of stroke rate and stroke length in visually impaired also matched those of Olympic swimmers although absolute stroke length values differed. Elite visually impaired swimmers achieve high post race lactate levels, and use arm coordination matching elite able-bodied swimmers. Aerobic capacity might, however, be low. Degree of visual impairment does not appear to be the main distinguishing factor of race performance
