Abstract

Kecepatan merupakan komponen biomotorik penting yang menentukan performa atlet sepak bola, terutama dalam situasi sprint pendek, akselerasi, dan perebutan bola. Penelitian ini bertujuan untuk menganalisis pengaruh berat badan terhadap kecepatan lari 30 meter pada atlet sepak bola. Pendekatan penelitian menggunakan metode kuantitatif dengan desain one group pretest–posttest dan melibatkan 30 atlet sepak bola. Data yang dianalisis meliputi berat badan, waktu tempuh 30 meter, dan kecepatan (m/s). Hasil analisis menunjukkan adanya korelasi sedang antara berat badan dan waktu sprint (r = 0.590), serta korelasi negatif antara berat badan dan kecepatan lari (r = –0.594). Temuan ini menunjukkan bahwa semakin tinggi berat badan atlet, semakin lambat waktu tempuh dan semakin rendah kecepatan sprintnya. Analisis regresi menunjukkan bahwa setiap kenaikan 1 kg berat badan meningkatkan waktu lari sekitar 0.015 detik. Penelitian ini menegaskan bahwa berat badan merupakan variabel antropometrik yang berpengaruh terhadap performa kecepatan, sehingga penting untuk dikontrol dalam pembinaan atlet sepak bola

Abstract

This study aims to analyze the effect of sports motivation on the athletic performance of female badminton athletes at Club Ardanoc Purwakarta. This research uses a quantitative correlational approach. The population is all female badminton athletes at Club Ardanoc, totaling 20 athletes, with a sample of 17 athletes selected through purposive sampling. Data were collected using a Likert-scale questionnaire (SS, S, RR, TS, STS) with 25 items measuring six motivation indicators: achievement desire, training enthusiasm, training discipline, self-confidence, environmental support, and training persistence. Athletic performance data were obtained through coach assessments covering playing technique, stroke accuracy, footwork, playing consistency, and match results using a scale of 1–5. Data analysis included validity and reliability tests, normality test, simple linear regression, t-test, and coefficient of determination. Results showed that sports motivation significantly affected female athlete performance (t-count = 5.847 & gt; ttable = 2.131, p & lt; 0.05). The coefficient of determination (R²) was 0.545, meaning that sports motivation contributed 54.5% to athlete performance. The findings suggest that coaches and club managers should design motivation-based training programs to optimize the performance of female badminton athletes.
