The expansion of sports in China is astounding. Given the country's focus on athletic achievement, it is crucial to comprehend the different facets of sports. This research examines China's athletic success in training, recuperation, motivation, and environment. The moderation-mediation strategy is used to understand how these variables affect athletic performance. This study fills a gap in understanding Chinese players' on-field performance. The study examined 355 Chinese athletes from various regions and sports. The sample has a balanced gender distribution, diverse age distribution, and representation from various regions. Furthermore, training programs, recovery strategies, motivation, psychological well-being, support systems, and experience levels influence athletes' sports performance. The study reveals that the coefficients indicate that training, recuperation tactics, motivation, and support systems affect athletic performance. Psychological health emerges as a critical mediator in explaining the effects of these factors on performance outcomes. Additionally, athlete experience moderates the influence of these variables, highlighting nuanced differences. These findings offer crucial insights for enhancing the performance of Chinese athletes. By adopting a moderation-mediation approach, this research illuminates the interconnected dynamics among key components, enriching our understanding of avenues for athlete improvement. Specifically, the results underscore the interconnectedness of athletes' psychological well-being, on-field experience, and competitive performance, emphasizing the importance of tailored interventions. This study could help Chinese politicians, sports psychologists, and coaches enhance athletes' performance.
