IntroductionKnowledge of Results（KR）是一种增强反馈的方法，其频率或时间取决于个人的表现。在以前的研究中，带宽（BW）KR没有建立根据个人的表现，因此，目前还不清楚如何BW应根据个人表现的变化设置。因此，本研究调查的有效性调整BW KR.MethodForty 7参与者被分为四组（对照，窄BW，宽BW，调整BW）。通过让参与者执行60秒的任务来测量抓握力任务的可调节性，每组接受不同的KR。我们使用绝对恒定误差（ACE）和可变误差（VE）作为运动的准确性和一致性的相应度量，并且BW之外的ACE的总和作为误差信息量的度量。测量（预测试，实践会议，并立即和延迟保留测试）进行了两天的过程中。ResultsThe调整后的BW组显示VE显着下降，与广泛的BW组在立即保留test.ConclusionThis研究部分表明调整后的BW KR的有效性相比，传统的BW KR。
IntroductionKnowledge of results (KR) is a method of augmented feedback where frequency or timing varies depending on the individual’s performance. In previous studies, bandwidth (BW) KR was not established according to the individual’s performance; thus, it is unclear how BW should be set based on changes in individual performance. Therefore, this study investigated the effectiveness of adjusted BW KR.MethodForty-seven participants were divided into four groups (control, narrow BW, wide BW, and adjusted BW). The adjustability of the grasping force task was measured by having participants perform the task for 60 seconds, with each group receiving a different KR. We used the absolute constant error (ACE) and variable error (VE) as respective measures of the accuracy and consistency of the movements, and the sum of ACEs outside of the BW as a measure of the amount of error information. Measurements (pretest, practice sessions, and immediate- and delayed-retention tests) were performed over the course of two days.ResultsThe adjusted BW group showed a significant decrease in VE compared with the wide BW group in the immediate-retention test.ConclusionThis study partially indicates the effectiveness of adjusted BW KR compared to traditional BW KR.
