We investigated whether performance gains achieved with deception persisted after the deception was revealed, and whether pacing strategy changed. 14 trained cyclists completed 4 simulated 4-km time trials (TT) on a cycle ergometer comprising familiarization and baseline trials (BAS), followed by "unaware" (of deception, UAW) and "aware" (of deception, AW) trials on separate days. In the UAW trial, participants competed against an on-screen avatar set at 102% of their baseline trial mean power output (Pmean) believing it was set at 100% of BAS Pmean. 24 h prior to the AW trial, participants were informed of the deception in the UAW trial. 4 participants did not improve in the UAW trial compared to BAS. 10 participants improved time to completion (TTC) and Pmean in the UAW and AW trials compared to BAS (p<0.03) with no significant differences between UAW and AW (p=1.0). Pacing strategy (at 0.5-km intervals) and RPE responses were unchanged (p>0.05) for these participants. In summary, deception did not improve performance in all participants. However, participants whose time trial performance improved following deception could retain their performance gains once the deception was revealed, demonstrating a similar pacing strategy and RPE response.
我们研究了在欺骗被揭露后，通过欺骗获得的成绩提升是否会持续，以及配速策略是否会改变。14名受过训练的自行车运动员在自行车测力计上完成了4次模拟4公里计时赛（TT），包括熟悉试验和基线试验（BAS），随后在不同日期进行“不知情”（欺骗，UAW）和“知情”（欺骗，AW）试验。在UAW试验中，参与者与一个屏幕上的虚拟形象竞争，该虚拟形象被设定为他们基线试验平均功率输出（Pmean）的102%，而他们认为其被设定为BAS Pmean的100%。在AW试验前24小时，参与者被告知UAW试验中的欺骗行为。与BAS相比，4名参与者在UAW试验中没有提高成绩。与BAS相比，10名参与者在UAW和AW试验中完成时间（TTC）和Pmean有所改善（p<0.03），UAW和AW之间无显著差异（p=1.0）。这些参与者的配速策略（以0.5公里间隔）和RPE反应没有变化（p>0.05）。总之，欺骗并非在所有参与者中都能提高成绩。然而，在欺骗后计时赛成绩有所提高的参与者，一旦欺骗被揭露，仍能保持他们的成绩提升，表现出相似的配速策略和RPE反应。
