Factors influencing sports performance: A multi-dimensional analysis of coaching quality, athlete well-being, training intensity, and nutrition with self-efficacy mediation and cultural values moderation.

This study examines the dynamic relationships between cultural values, training intensity, nutrition, self-efficacy, and coaching quality on Chinese athletes' performance. Bandura's social cognitive theory and cultural psychology ideas enlightened the multi-faceted sports performance analysis. A detailed questionnaire was employed to obtain data from 880 athletes from various places and sports backgrounds. Structural Equation Modeling (SEM) was used for empirical analysis. The results show a significant positive association between coaching quality (β = 0.62, p < 0.001), athlete well-being (β = 0.48, p < 0.001), training intensity (β = 0.55, p < 0.001), nutrition (β = 0.42, p < 0.001), self-efficacy (β = 0.57, p < 0.001), and sports performance. Coaching quality appeared as a critical component. Athletes performed better when they felt their instructors were performing better. Diet, training intensity, and health affected athletes' performance, highlighting the necessity for athlete development. Athletes' confidence in their performance is mediated by coaching, well-being, training, nutrition, and performance. These correlations were further impacted by cultural values, highlighting the need to consider cultural context while attempting to enhance athlete performance outcomes. The study concludes that cultural values, self-efficacy, training, nutrition, coaching, and health are crucial to Chinese athletes' success.
