【 摘 要 】

Twelve male, categorized United States Cycling Federation (USCF) cyclists (23.1 yrs, 70 in, 163 lbs, 60.37 Q02 ml . kg-1 . min-1, 4.37 V OL~ m in-1) performed 3 submaximal tests while riding a standard, USCF legal road bicycle mounted on a Giant C-Force indoor trainer. Seat position was altered for each submaximal test (Forward = 88 degrees, Middle = 85 degrees, Back = 82 degrees). The Ss cycled at a constant workload of 19 mph throughout all tests.This workload was attained using 3 varying cadences: Fast = 130 rpm, Medium = 90 rpm, Slow = 50 rpm. HR. RER, RPE VEO2, VE, and VO2 ml. kg-1.m in-1 & ~ VO2 L min -1 were compared with seat position coupled with cadence and cadence independent of seat position. The data were collapsed for each stage of each test. For each S there were 9 submax values for each variable analyzed by a 2-way ANOVA with repeated measures. Significant values were further analyzed using a Tukey;;s post hoc test. No significant differences in physiological variables were found between 3 seat positions at 3 different cadences (p > .05). Significant differences were found between varying cadences (p > .05) independent of seat position. These differences demonstrated significant increases in physiologicai variables at high cadences.
