To compare the effect of three different feedback modalities on swimming pace, sixteen male swimmers and triathletes participated in this study. Each participant swam 3 x 400 m, one for each feedback modality, swimming front crawl at 80% of their individual swimming critical speed. Three feedback modalities were examined: self-pacing, real time visual feedback and real time voice feedback. The swimmers adopted a fast start in all feedback modalities. In the real time voice feedback modality, the data recorded during the second lap (200 m) showed a significant improvement of their swimming pace approaching the swimming pace intended (-1.47 s, p < .01, medium effect size 0.79). A significant improvement toward the swimming pace intended was also noticed at the third split time (300 m) (0.05 s, p < .01, large effect size 0.81) and at the fourth split time (400 m) (0.46 s, p < .01, medium effect size 0.76). In self-pacing, the swimmers were not able to swim in line with the swimming pace intended. In real time visual feedback modality, the swimmers did not show a significant improvement approaching the swimming pace intended. The results revealed that communication with the swimmers using the real time voice feedback induced a significant improvement in their swimming pace and could help the athletes to swim with accurate and consistent pace.
为比较三种不同反馈方式对游泳速度的影响,16名男性游泳运动员和铁人三项运动员参与了本研究。每位参与者游3组400米,每种反馈方式各一组,采用自由泳姿势,以个人游泳临界速度的80%进行游泳。研究考察了三种反馈方式:自我 pacing、实时视觉反馈和实时语音反馈。在所有反馈方式中,游泳者都采用了快速出发。在实时语音反馈方式中,第二圈(200米)记录的数据显示,他们的游泳速度显著提高,接近预期游泳速度(-1.47秒,p <.01,中等效应量0.79)。在第三个分段时间(300米)(0.05秒,p <.01,大效应量0.81)和第四个分段时间(400米)(0.46秒,p <.01,中等效应量0.76)时,也注意到朝着预期游泳速度有显著提高。在自我 pacing 方式中,游泳者无法按照预期游泳速度游泳。在实时视觉反馈方式中,游泳者在接近预期游泳速度方面没有表现出显著提高。结果表明,使用实时语音反馈与游泳者进行沟通可显著提高他们的游泳速度,并有助于运动员以准确且一致的速度游泳。
