Abstract

This study aims to analyze the relationship between Body Mass Index (BMI) and cardiovascular endurance among students of the Sport Science Study Program at Singaperbangsa University, Karawang. The background of this study is based on the importance of cardiovascular fitness as an indicator of health and physical performance, as well as the increasing variability of nutritional status among students due to lifestyle changes. This study used a correlational design with purposive sampling, involving 30 students aged 18–25 years who met the inclusion criteria regarding health conditions and readiness to participate in fitness testing. Body Mass Index (BMI) was measured through height and weight assessments, while cardiovascular endurance was evaluated using a bleep test to obtain aerobic capacity scores. Descriptive results showed that the students' endurance levels were categorized as fair to good, with an average score of 8.43 ± 0.917. Meanwhile, the average BMI was 21.91 ± 3.28, categorized as normal, although the range indicates variations in nutritional status from underweight to overweight. Pearson correlation analysis revealed a significant positive relationship between BMI and cardiovascular endurance (r = 0.401; p = 0.031). This finding suggests that changes in BMI contribute to variations in students' endurance, particularly in the context of exercise science students who tend to have higher muscle mass, meaning that increased BMI may reflect greater muscle mass than fat mass. This study emphasizes that BMI remains relevant as a baseline indicator for assessing students' cardiovascular capacity, although its interpretation should be accompanied by more specific body composition measurements.

Abstract

Power tendangan Mae Geri merupakan salah satu komponen biomotor penting dalam cabang olahraga karate, di mana kekuatan dan kecepatan otot tungkai berperan dominan dalam menghasilkan tendangan yang efektif. Latihan leg press merupakan salah satu bentuk latihan kekuatan yang dapat memengaruhi peningkatan power otot kaki melalui manipulasi intensitas beban. Penelitian ini bertujuan untuk mengetahui hubungan antara intensitas latihan leg press dengan peningkatan power tendangan Mae Geri pada atlet karate. Metode penelitian yang digunakan adalah metode korelasional dengan pendekatan kuantitatif. Sampel penelitian berjumlah 30 atlet karate yang dipilih menggunakan teknik purposive sampling. Variabel intensitas latihan leg press diukur melalui persentase beban latihan (%1RM), volume latihan, dan frekuensi mingguan, sedangkan power tendangan Mae Geri diukur menggunakan alat tes power tendangan berbasis sensor. Analisis data dilakukan menggunakan uji korelasi Pearson untuk mengetahui hubungan antara kedua variabel. Hasil penelitian menunjukkan adanya hubungan positif yang signifikan antara intensitas latihan leg press dengan peningkatan power tendangan Mae Geri pada atlet karate (r = 0,67; p < 0,05). Temuan ini mengindikasikan bahwa semakin tinggi intensitas latihan leg press yang dilakukan, maka semakin besar peningkatan power tendangan Mae Geri yang dihasilkan. Dapat disimpulkan bahwa intensitas latihan leg press memiliki peranan penting dalam meningkatkan power tendangan Mae Geri pada cabang olahraga karate. Pelatih disarankan menyusun program latihan leg press dengan pengaturan intensitas yang tepat untuk mengoptimalkan performa tendangan atlet

Abstract

Pickleball has experienced rapid growth in participation; however, this trend has been accompanied by an increasing incidence of musculoskeletal injuries. This study aimed to assess injury risk among Indonesian pickleball athletes using the Functional Movement Screen (FMS) and to examine its potential as a predictive tool for injury prevention. A quantitative prospective cohort design was employed, involving 35 athletes (30 amateurs and 5 professionals) monitored over a 12-month competitive season. Baseline FMS assessments were administered by certified raters, and injuries were recorded weekly. Injury was defined as any condition resulting in at least one day of absence from training or competition. The results showed that professional players demonstrated significantly higher FMS scores (mean = 16.0) compared to amateur players (mean = 12.3). During the season, 18 injuries were documented, predominantly knee and ankle injuries among amateurs and shoulder injuries among professionals. Logistic regression analysis indicated that lower FMS scores were significantly associated with a higher risk of injury, with each one-point decrease in FMS score increasing injury risk by 2.85 times (OR = 2.85; 95% CI = X–X; p < 0.05). These findings suggest that FMS is an effective screening and predictive tool for analyze injury risk in pickleball athletes and can support the development of targeted preventive training programs, particularly for amateur players. Notably, this study contributes novel evidence to the limited body of research examining injury risk profiling in pickleball athletes using validated movement screening tools, especially within the Indonesian context.
