【 摘 要 】

The drafting effect has not been thoroughly studied in running. The purpose of this studywas to compare VOz, HR, BLa, and RPE during 6-minute running bouts with variationsof wind velocities and with drafting. Six collegiate runners (3 male, 3 female) performeda maximal GXT and six, 6-minute running trials against a wind velocity of 0 m*ii, 3.64m*s;;, and 4.7 mes;;. Three of these trials were done when draftirlg off a second runner,one at each wind velocity and three trials without. Comparisons were made usingrepeated measures ANOVA. Volume of oxygen consumed (V02) was significantlylower (p = 0.02) when drafting at a wind velocity of 4.7 m*ii (53.9 + 6.42 vs. 52.4 +7.32) which equates a 2.9% reduction in VOz. W E was significantly lower (p = 0.029)when drafting at a wind velocity of 4.7 m*s-;; (5.5 * 1.23 vs. 3.8 * 0.75). There was nosignificant difference in HR or BLa at any wind velocity. The results are in partialagreement with similar research. The drafting effect in running may help coaches andrunners to train for performances and to develop time and energy saving racing strategies
