The development of competitive Muay Thai requires not only adequate technical and physical preparation but also organizational support and strong athlete motivation to sustain training commitment and competitive performance. In regional athlete-development settings, service quality and training motivation may play different but complementary roles in shaping performance outcomes. This study aimed to examine the partial and simultaneous effects of service quality and training motivation on the performance of Muay Thai athletes in Tanah Laut Regency. A quantitative correlational
Design: with an ex post facto approach was employed. The population consisted of 34 active male and female Muay Thai athletes, all of whom were included using total sampling. Data were collected through structured questionnaires measuring service quality, training motivation, and athlete performance. The instruments were subjected to validity and reliability testing before data collection. Statistical analysis was performed using IBM SPSS Statistics through descriptive analysis, classical assumption tests, multiple linear regression, partial t-tests, an F-test, and the coefficient of determination. The
Results: showed that service quality did not have a statistically significant partial effect on athlete performance (p = .480 > .05). In contrast, training motivation significantly predicted athlete performance (p < .001). Simultaneously, service quality and training motivation produced a significant regression model (F = 31.314; p < .001). The coefficient of determination (R² = .669) indicated that both predictors collectively explained 66.9% of the variance in athlete performance, while the remaining 33.1% was attributable to other factors outside the model. These
Findings: highlight training motivation as the principal significant predictor and suggest that athlete-development strategies should strengthen motivational processes while continuously improving organizational and coaching services as components of a supportive performance environment.
