HUBUNGAN BERAT BADAN DAN TINGGI BADAN TERHADAP KECEPATAN RENANG GAYA BEBAS 50 METER PADA ATLET BULAKAN AQUATIC CLUB BATANG TABIK KABUPATEN LIMA PULUH KOTA

Abstract

This study aimed to determine the relationship between body weight and body height on 50-meter freestyle swimming speed among Bulakan Aquatic Club athletes. This research employed a quantitative correlational design. The population consisted of 10 athletes and all were selected as samples through total sampling. Data collection was conducted using digital scales, stadiometer measurements, and a 50-meter freestyle swimming test. Data analysis included descriptive statistics, Shapiro-Wilk normality test, Pearson Product Moment correlation, coefficient of determination, multiple correlation, and F-test. The results indicated a significant relationship between body weight and freestyle swimming speed (r = -0.637; p = 0.048) with a contribution of 40.6%. Body height also showed a significant relationship with freestyle swimming speed (r = -0.680; p = 0.031) with a contribution of 46.24%. Simultaneously, body weight and body height produced R = 0.680 and R² = 0.462. However, the F-test yielded a significance value of 0.114 (p > 0.05), indicating no statistically significant relationship simultaneously. Therefore, body weight and body height have significant partial relationships but not a significant simultaneous relationship with 50-meter freestyle swimming speed.
