<![CDATA[Exercise motivation is a key factor in developing persistence, discipline, and long-term commitment to physical activity, particularly among adolescents who are in a critical transitional stage of development. One strategy that has been widely recognized for enhancing motivation in sports is goal setting. Therefore, this study aimed to examine the effect of goal setting based on the SMART-ER principle on adolescents’ exercise motivation. An experimental method was employed involving 16 junior high school students participating in a boys’ basketball extracurricular program. The instrument used was the Sport Motivation Scale-II (SMS-II), which had undergone cross-cultural adaptation. The instrument demonstrated validity coefficients ranging from r = .455 to .911 and a high reliability coefficient (α = .946). The collected data were analyzed using descriptive statistics, normality testing, and hypothesis testing through the Paired Sample t-test. The results revealed a significant effect of applying SMART-ER-based goal setting on adolescents’ exercise motivation (p = .004). More specifically, five motivation subscales showed improvement, while one subscale decreased. In conclusion, the application of goal setting using the SMART-ER principle can significantly enhance adolescents’ motivation to engage in exercise and sports training.]]>
