Analysis Body Mass Index (BMI) Status Among Basketball Athletes at SMK Negeri 1 Semarang

Abstract

To support optimal performance during basketball games without disruption, an athlete must maintain an ideal body composition. Ideal body composition reflects an athlete's health status, which can be assessed through anthropometric measurements. This study aims to determine the body mass index (BMI) of basketball athletes at State Vocational High School 1, Semarang, to provide a summary of their weight classification. Sample: The subjects of this study were 12 basketball athletes from State Vocational High School 1, Semarang. Method: This research used the ex-post-facto method. The instruments used were body weight and height to determine BMI. Results: The Body Mass Index (BMI) of the basketball athletes at State Vocational High School 1 Semarang showed that three athletes, or 25%, were in the underweight category, eight athletes, or 67%, were in the normal weight category, one athlete, or 8%, was in the overweight category, and there were no athletes in the obesity or severe obesity categories. Thus, the average body mass index (BMI) of the basketball athletes at State Vocational High School 1 Semarang falls within the normal category, indicating good results for their performance. One important predictor of motor ability is the combination of height and weight, as these two factors significantly affect an athlete's motor skills. Conclusion: Body Mass Index (BMI) is one way to assess the physical condition of athletes to prepare and maintain their performance in both the short and long term.
