Integration of wearable technologies in monitoring physical performance and psychological stress in tennis players

Professional sports actively leverage advanced technologies, integrating them to enhance performance outcomes. The primary objective of this study is to quantitatively assess the impact of wearable technologies (such as smartwatches, biosensor wristbands, sports GPS trackers, and electromyographic sensors) on key physiological and psychological indicators, including heart rate (HR), heart rate variability (HRV), recovery rate (HRR), psychological stress levels, and stress management capabilities among professional Chinese tennis players. The study sample comprised 100 participants (54 males and 46 females, with a mean age of 21.52 years). The research employed objective physiological measurements alongside the Perceived Stress Scale (PSS-10) as assessment tools. The findings confirm that wearable technologies contribute to improvements in the studied parameters and a reduction in stress levels among professional tennis players. In the intervention group, heart rate data indicated superior cardiorespiratory fitness, while the recovery rate following exertion was significantly higher among athletes using wearable devices (p < 0.001). Heart rate variability measurements demonstrated that tennis players in the intervention group exhibited a more favorable balance of autonomic regulation and increased parasympathetic activity, indicative of more effective recovery mechanisms. Psychological stress levels in the intervention group were significantly lower, whereas stress resilience was higher (both cases at p < 0.001). Pearson's correlation analysis revealed significant associations among the studied constructs. The results highlight the practical value of wearable technologies in professional tennis, further expanding the current scientific knowledge on their applicability and effectiveness.
