Abstract

ABSTRACT

The relationships between six indices of aerobic capacity and bicycle road race performance were determined with 13 elite women cyclists competing in the 14-day 1990 Ore-Ida Women's Challenge Centennial Tour of Idaho. Maximal oxygen uptake JOURNAL/jscr/04.02/00124278-199311000-00002/ENTITY_OV0312/v/2017-07-20T235140Z/r/image-pngO2max expressed in ml · kg−1 · min−1 and L · min−1, HR in beats · min−1, JOURNAL/jscr/04.02/00124278-199311000-00002/ENTITY_OV0312/v/2017-07-20T235140Z/r/image-pngE in L · min−1, JOURNAL/jscr/04.02/00124278-199311000-00002/ENTITY_OV0312/v/2017-07-20T235140Z/r/image-pngE/JOURNAL/jscr/04.02/00124278-199311000-00002/ENTITY_OV0312/v/2017-07-20T235140Z/r/image-pngO2 in L · min−1/L · min−1, and HR/JOURNAL/jscr/04.02/00124278-199311000-00002/ENTITY_OV0312/v/2017-07-20T235140Z/r/image-pngO2 in beats · min−1/L · min−1 were collected for each subject in the laboratory during a 36-hr rest period prior to the event. Data were subsequently correlated with each subject's finishing times for 16 of the 17 races that made up the event. Finishing time was found to be significantly (p < 0.05) correlated with both relative (ml · kg−1 · min−1) and absolute (L · min−1) JOURNAL/jscr/04.02/00124278-199311000-00002/ENTITY_OV0312/v/2017-07-20T235140Z/r/image-pngO2max, with correlation coefficients ranging from −.56 to −.91. Eleven of the correlations between relative JOURNAL/jscr/04.02/00124278-199311000-00002/ENTITY_OV0312/v/2017-07-20T235140Z/r/image-pngO2max and finishing time, however, were significant to the p < 0.01 level, and were more frequent than those using absolute JOURNAL/jscr/04.02/00124278-199311000-00002/ENTITY_OV0312/v/2017-07-20T235140Z/r/image-pngO2max. In addition, four coefficients were found to be significant between HR/JOURNAL/jscr/04.02/00124278-199311000-00002/ENTITY_OV0312/v/2017-07-20T235140Z/r/image-pngO2 and performance. These later results, however, should be considered in light of the many variables that can affect heart rate during exercise. Overall, these data suggest the relative JOURNAL/jscr/04.02/00124278-199311000-00002/ENTITY_OV0312/v/2017-07-20T235140Z/r/image-pngO2max may account for as much as 82% of bicycle racing performance in multiday road racing that includes significant amounts of climbing.
