We investigated the effects of different performance goals (best time beat the opponent) on pacing behaviour during a 10-km cycling race and explored the influence of different performance level of opponents on ratings of perceived exertion (RPE), affective feelings and self-efficacy. Thirteen cyclists performed two time-trials (TT) and two races against a faster (FAST +6%) or a slower (SLOW -3%) virtual opponent. Power output (PO), RPE, affective feelings and self-efficacy were recorded at each kilometre point. Race average and race phases [starting (P1 = first kilometre); first half (P2 = 2nd-5th kilometre); second half (P3 = 6th-9th kilometre) and final sprint (FS = last kilometre)] were analysed. There was no difference in performance, assessed by race time between conditions ( = .84). PO during TT was lower in P3 compared to FS ( = .03; ES 0.6; 90%CI 0.4-0.7). In SLOW and FAST, PO was higher in P1 compared to other phases ( < .05). PO in FS was higher in TT compared to FAST ( = .01; ES -0.97; 90%IC -1.4 to -0.5). RPE increased and affective feelings decreased during all conditions. Self-efficacy was stable through TT and SLOW, but decreased during FAST with higher values in P1 compared to P2 ( = .01; ES -1.1; 90%IC -1.6 to -0.6), P3 ( < .001; ES -2.2; 90%IC -2.8 to -1.6) and FS ( < .001; ES -2.6; 90%IC -3.3 to -1.8). Pacing behaviour, specifically starting and final sprint, was affected by virtual opponents independent of performance level, demonstrating the importance of goal orientation.Adjustments in exercise intensity result from a complex decision-making process involving physiological, psychological, environmental and tactical information.Goal pursuit is an important determinant of pacing behaviour since athletes must balance their efforts with expectations of success.A competitive environment may be included to motivate participants to maintain their effort and at the same time to improve their self-confidence.The presence of a final sprint seems to be related to the goal orientation and perceived outcomes of success or failure.
我们研究了不同的表现目标(最佳时间击败对手)对10公里自行车比赛中配速行为的影响,并探讨了不同表现水平的对手对主观用力程度(RPE)、情感感受和自我效能感的影响。13名自行车运动员进行了两次计时赛(TT),以及与速度更快(FAST +6%)或速度更慢(SLOW -3%)的虚拟对手进行的两场比赛。在每公里处记录功率输出(PO)、RPE、情感感受和自我效能感。分析了比赛平均成绩和比赛阶段[起跑阶段(P1 = 第一公里);前半程(P2 = 第2 - 5公里);后半程(P3 = 第6 - 9公里)和最后冲刺阶段(FS = 最后一公里)]。不同条件下通过比赛时间评估的表现没有差异( = 0.84)。与最后冲刺阶段相比,计时赛中P3阶段的功率输出较低( = 0.03;效应量0.6;90%置信区间0.4 - 0.7)。在SLOW和FAST条件下,与其他阶段相比,P1阶段的功率输出更高( < 0.05)。与FAST条件相比,计时赛中最后冲刺阶段的功率输出更高( = 0.01;效应量 -0.97;90%置信区间 -1.4至 -0.5)。在所有条件下,主观用力程度增加而情感感受下降。自我效能感在计时赛和SLOW条件下保持稳定,但在FAST条件下下降,P1阶段的值高于P2阶段( = 0.01;效应量 -1.1;90%置信区间 -1.6至 -0.6)、P3阶段( < 0.001;效应量 -2.2;90%置信区间 -2.8至 -1.6)和FS阶段( < 0.001;效应量 -2.6;90%置信区间 -3.3至 -1.8)。配速行为,特别是起跑和最后冲刺,受到虚拟对手的影响,与表现水平无关,这表明目标导向的重要性。运动强度的调整源于一个复杂的决策过程,涉及生理、心理、环境和战术信息。目标追求是配速行为的一个重要决定因素,因为运动员必须在努力与对成功的期望之间取得平衡。可以引入竞争环境来激励参与者保持努力,同时提高他们的自信心。最后冲刺阶段的存在似乎与目标导向以及对成功或失败的感知结果有关。
