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。
