Abstract

This study aims to examine the relationship between Body Mass Index (BMI) and cardiovascular fitness levels among students at SMP IT Darul Wahdah Gerung in 2025. A quantitative approach with a correlational research design was employed. Data were collected by measuring students’ body weight and height to calculate BMI, as well as administering the 12-minute Cooper test to assess cardiovascular fitness levels. Pearson’s correlation test was used for data analysis. The results revealed that; (1) there was a significant relationship between Body Mass Index (BMI) and students’ cardiovascular fitness levels, as indicated by a correlation coefficient of −0.689 and a significance value of 0.005 (p < 0.05). Therefore, the null hypothesis (H₀) was rejected, and the alternative hypothesis (H₁) was accepted. (2) The negative correlation coefficient indicates a significant inverse relationship, meaning that higher BMI values are associated with lower cardiovascular fitness levels, and vice versa.

Abstract

This observational study with a cross-sectional design analyzed the effect of injury management knowledge levels on injury incidence among 108 Undikma Physical Education student athletes selected via purposive sampling. Using a Guttman scale questionnaire and injury history, the data were analyzed using descriptive statistics, the Chi-square test, the t-test, and multivariate logistic regression. Descriptive results showed a very high injury incidence rate of 90.7% (mostly minor injuries), with an average knowledge score of 19.2 ± 2.8 on a 25-point scale. Bivariate analysis detected significant associations between educational history (p=0.048) and knowledge scores (p=0.002) and injury incidence. Furthermore, the final logistic regression model confirmed that educational history (OR=3.330; 95% CI: 1.026–10.803) and higher knowledge scores (OR=0.750; 95% CI: 0.610–0.922) acted as significant independent protective factors in reducing the risk of injury. Based on these findings, it is concluded that good understanding and exposure to effective education minimize the incidence of injuries among student-athletes; therefore, the implementation of a comprehensive and easily accessible injury management education program is a crucial recommendation that must be realized immediately.
