Abstract
This study aims to analyze the relationship between physical development, cognitive abilities, and intrinsic motivation with the level of physical fitness in adolescents. Physical fitness is an important aspect of adolescent development, but the factors influencing it still need further investigation. This cross-sectional study involved 200 adolescents aged 13-18 years randomly selected from several secondary schools. Physical development was measured through body mass index and sexual maturity level. Cognitive abilities were assessed using standardized tests, while intrinsic motivation was measured with a self-report questionnaire. The level of physical fitness was determined through a series of fitness tests covering cardiorespiratory endurance, muscle strength, and flexibility. Multiple regression analysis was used to test the relationships between variables. The results showed a significant positive correlation between physical development, cognitive abilities, and intrinsic motivation with the level of physical fitness in adolescents. These findings emphasize the importance of a holistic approach in improving adolescent physical fitness, considering not only physical aspects but also cognitive and psychological factors. The implications of this research can be used to develop more effective intervention programs to enhance physical fitness in adolescents.
