To verify the affective feelings (AFs) and rating of perceived exertion (RPE) responses during a 10-km competitive head-to-head (HTH) running race and compare them with a time-trial (TT) running race.
Fourteen male runners completed 2 × 10-km runs (TT and HTH) on different days. Speed, RPE, and AF were measured every 400 m. For pacing analysis, races were divided into the following 4 stages: first 400 m (F400), 401-5000 m (M1), 5001-9600 m (M2), and the last 400 m (final sprint).
Improvement of performance was observed (39:32 [02:41] min:s vs 40:28 [02:55] min:s; P = .03; effect size = -0.32) in HTH compared with TT. There were no differences in either pacing strategy or RPE between conditions. AFs were higher during the HTH, being different in M2 compared with TT (2.09 [1.81] vs 0.22 [2.25]; P = .02; effect size = 0.84).
AFs are directly influenced by the presence of opponents during an HTH race, and a more positive AF could be involved in the dissociation between RPE and running speed and, consequently, the overall race performance.
验证在10公里竞争性迎面（HTH）跑步比赛中的情感感受（AFs）和自觉用力程度评级（RPE）反应，并将其与计时赛（TT）跑步比赛进行比较。
14名男性跑步者在不同日期完成了2次10公里跑（TT和HTH）。每400米测量速度、RPE和AF。为了进行配速分析，比赛分为以下4个阶段：前400米（F400）、401 - 5000米（M1）、5001 - 9600米（M2）和最后400米（最后冲刺）。
与TT相比，HTH的成绩有所提高（39:32 [02:41] 分:秒 vs 40:28 [02:55] 分:秒；P = 0.03；效应量 = -0.32）。两种情况下的配速策略或RPE均无差异。HTH期间的AFs更高，M2阶段与TT相比有所不同（2.09 [1.81] vs 0.22 [2.25]；P = 0.02；效应量 = 0.84）。
在HTH比赛中，AFs直接受到对手在场的影响，更积极的AF可能与RPE和跑步速度之间的解离有关，进而与整体比赛成绩有关。
