Abstract
This study examines the legal implications of implementing wearable technology in professional sports, focusing on European football leagues. As the adoption of wearable devices in sports continues to grow, it raises significant legal concerns regarding privacy, data protection, and athlete rights. The research employs a mixed-methods approach, combining qualitative analysis of legal frameworks and quantitative survey data from 150 professional footballers across top European leagues. Key findings reveal that 78% of surveyed athletes express concerns about the potential misuse of their biometric data collected through wearable devices (p < 0.001). The study identifies three primary legal challenges: (1) data ownership and control, (2) informed consent and voluntary participation, and (3) potential discrimination based on biometric data in contract negotiations. A comparative analysis of regulatory approaches in different European countries shows significant variations, with only 40% having specific legislation addressing wearable technology in sports.The research also explores the intersection of wearable technology with existing sports law, including doping regulations and fair play principles. A chi-square test indicates a significant association between athletes' awareness of legal rights and their willingness to use wearable technology (χ2 = 15.7, p < 0.01).This study contributes to the growing body of literature on sports law and technology by providing empirical evidence and legal analysis specific to the European football context. The findings have important implications for policymakers, sport’s governing bodies, and athletes' unions in developing comprehensive frameworks to address the legal challenges posed by wearable technology in professional sports.
