Abstract

Background/Objectives: In tennis, timing plays a crucial factor as it influences the technique and effectiveness of strokes and, therefore, matches results. However, traditional technical evaluation methods rely on subjective observations or video motion-tracking technology, mainly focusing on spatial components. This study evaluated the reliability of an acoustic detection system in analyzing key temporal elements of the game, such as the rally rhythm and timing of strokes. Methods: Based on a machine learning algorithm, the proposed acoustic detection system classifies the sound of the ball's impact on the racket and the ground to measure the time between them and give immediate feedback to the player. We performed trials with expert and amateur players in controlled settings. Results: The ML algorithm showed a detection accuracy higher than 95%, while the average accuracy of the whole system that was applied on-court was 85%. Moreover, this system has proven effective in evaluating the technical skills of a group of players on the court and highlighting their areas for improvement, showing significant potential for practical applications in player training and performance analysis. Conclusions: Quantitatively assessing timing offers a new perspective for coaches and players to improve performance and technique, providing objective data to set training regimens and optimize game strategies.

基于机器学习的声音检测系统的网球计时评估:一项试点研究。
背景/目的:在网球比赛中,时机是一个至关重要的因素,因为它会影响击球的技术和效果,从而影响比赛结果。然而,传统的技术评价方法依赖于主观观察或视频运动跟踪技术,主要关注空间分量。这项研究评估了声学检测系统在分析比赛关键时间元素(如拉力赛节奏和击球时间)方面的可靠性。方法:提出的声音检测系统基于机器学习算法,对球撞击球拍和地面的声音进行分类,测量两者之间的时间间隔,并及时反馈给球员。我们在受控环境中对专家和业余玩家进行了试验。结果:ML算法的检测准确率高于95%,而整个系统在场上应用的平均准确率为85%。此外,该系统已被证明可以有效地评估一组球员在球场上的技术技能,并指出他们需要改进的地方,在球员训练和表现分析方面显示出巨大的实际应用潜力。结论:定量评估时机为教练员和运动员提高成绩和技术水平提供了新的视角,为制定训练方案和优化比赛策略提供了客观数据。
