The study investigated responses to false feedback in laboratory cycling. Seven male competitive cyclists (age; M = 34.14 years, SD = 7.40) completed two ergometer time-trials, one each with false negative and false positive feedback (time ± 5 %). MANOVA indicated main effects for condition [F(17, 104) = 9.42, p < 0.001], and mile [F(153, 849) = 1.58, p < 0.001], but no interaction [F(153, 849) = 0.470, p = 1.00]. No between-condition differences in power (F = 0.129, p = 0.720) or time to completion (F = 1.011, p = 0.338) were observed. Positive feedback was associated with higher glucose (F = 25.988, p < 0.01), happiness (F = 6.097, p = 0.015) and calmness (F = 4.088, p = 0.045). Positive feedback was also associate with lower oxygen uptake (F = 8.830, p = 0.004), anxiety (F = 5.207, p = 0.024), gloominess (F = 6.322, p = 0.013), sluggishness (F = 11.650, p = 0.001), downheartedness (F = 15.844, p = 0.001), effort required to regulate emotion (F = 13.798, p = 0.001), and a trend towards lower lactate production (F = 3.815, p = 0.053). Data suggest that positive emotions and reduced metabolic cost of performance were associated with positive feedback.
该研究调查了实验室自行车运动中对虚假反馈的反应。七名男性竞技自行车手（年龄；M=34.14 岁，SD=7.40）各完成了两次测功计计时赛，一次为假阴性反馈，一次为假阳性反馈（时间±5%）。MANOVA 表明条件有主要影响[F(17, 104)=9.42，p<0.001]，英里数有主要影响[F(153, 849)=1.58，p<0.001]，但无交互作用[F(153, 849)=0.470，p=1.00]。在功率方面没有观察到条件之间的差异（F=0.129，p=0.720）或完成时间的差异（F=1.011，p=0.338）。阳性反馈与较高的血糖（F=25.988，p<0.01）、幸福感（F=6.097，p=0.015）和平静感（F=4.088，p=0.045）有关。阳性反馈还与较低的耗氧量（F=8.830，p=0.004）、焦虑（F=5.207，p=0.024）、忧郁（F=6.322，p=0.013）、懒散（F=11.650，p=0.001）、沮丧（F=15.844，p=0.001）、调节情绪所需的努力（F=13.798，p=0.001）以及乳酸生成减少的趋势（F=3.815，p=0.053）有关。数据表明，积极的情绪和降低的运动代谢成本与正反馈有关。
