摘要

该研究旨在评估使用智能手机的高速摄像头估算跑跳(RJ)高度的有效性和准确性,并评估通过智能手机提供的口头和视觉反馈在增强熟练运动员的 RJ 动作和高度方面的有效性。20 名男子大学生篮球运动员被随机分配到口头反馈(OF)组或口头和视觉反馈(OVF)组。最初,参与者在力板上进行 RJ,同时用 iPhone 进行录像(240 帧/秒)。通过视频、力板数据和骨盆标记的位置数据(分别为 JHiPhone、JHFP 和 JHRM)估算跳跃高度。随后,每个小组都收到了根据 RJ 视频量身定制的反馈。反馈后,参与者再次进行 RJ,并重新估算跳跃高度。与 JHRM 相比,JHiPhone 的测量结果系统性更高,但随机误差可接受,重现性极佳,与 JHFP 和 JHRM 呈强正相关。只有 OVF 组在反馈后的跳跃高度上有明显改善。我们的研究结果表明,JHiPhone 是一种适用于运动环境的宝贵而准确的工具。此外,结果还表明,使用智能手机进行视觉反馈是有效的,应与口头反馈相辅相成,以提高真实运动环境中的 RJ 跳高。

Immediate effects of different feedback methods on running jump height and motion improvement in male college basketball players
The study aimed to assess the validity and accuracy of estimating running jump (RJ) height using the high-speed camera of a smartphone and to evaluate the effectiveness of oral and visual feedback via a smartphone in enhancing RJ movements and height in skilled athletes. Twenty male college basketball players were randomly assigned to either the Oral Feedback (OF) or Oral and Visual Feedback (OVF) group. Initially, participants performed RJs on force plates while being recorded with an iPhone (240 fps). Jump heights were estimated using the video, force plate data, and position data from pelvic markers (JHiPhone, JHFP, and JHRM, respectively). Subsequently, each group received tailored feedback based on the RJ video. After feedback, participants performed RJs again, and jump heights were re-estimated. The JHiPhone measurements were systematically higher but showed acceptable random errors compared to JHRM, with excellent reproducibility and strong positive correlations with JHFP and JHRM. Only the OVF group showed significant improvements in jump height post-feedback. Our results indicate that JHiPhone is a valuable and accurate tool for sports settings. Additionally, the results demonstrated that visual feedback using a smartphone is effective and should complement oral feedback to enhance RJ jump height in real sports settings.

期刊介绍: Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome. These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
