Abstract

This study aimed to investigate the application of Artificial Intelligence (AI) via the SwingVision application for match analysis and performance enhancement in soft tennis. Employing a video-based methodology, a single match video (720p resolution, 60 fps, .MP4 format) was processed using computer vision algorithms. The results demonstrated that the application effectively adapted the tennis scoring system to the soft tennis context and synthesized insights across four key dimensions: 1) automated point-by-point notational analysis identifying the causes of winning and losing points; 2) technical profiling through the analysis of spin mechanics and directional shot distribution; 3) comparative tactical analysis identifying opponent weaknesses using spatial speed and accuracy metrics; and 4) physiological load assessment based on rally duration. However, because the application was originally developed for tennis, its interpretation within the soft tennis context presents certain limitations related to differences in ball physics, which may affect the accuracy of speed calculations. Nevertheless, this study highlights the technology as an accessible and high-efficiency innovation that enables soft tennis coaches and athletes to adopt data-driven coaching methodologies in preparation for international competition.
