Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh latihan vertical kicking terhadap peningkatan daya tahan otot tungkai pada atlet Kelompok Umur III Club Renang Balaena Rex Aequos. Penelitian menggunakan pendekatan kuantitatif dengan metode eksperimen semu (quasi experimental) melalui desain One Group Pretest-Posttest. Sampel penelitian berjumlah 20 atlet yang ditentukan menggunakan teknik purposive sampling. Pengumpulan data dilakukan melalui tes daya tahan otot tungkai yang diberikan sebelum perlakuan (pretest) dan sesudah perlakuan (posttest). Data yang diperoleh dianalisis menggunakan statistik deskriptif, uji normalitas Shapiro-Wilk, dan uji Paired Sample t-Test dengan bantuan program SPSS. Hasil analisis deskriptif menunjukkan bahwa rata-rata nilai pretest sebesar 48,65 meningkat menjadi 89,50 pada posttest, dengan peningkatan sebesar 40,85 poin. Hasil uji normalitas menunjukkan nilai signifikansi sebesar 0,079 (>0,05), sehingga data berdistribusi normal. Selanjutnya, hasil uji Paired Sample t-Test menunjukkan nilai signifikansi (Sig. 2-tailed) sebesar 0,000 (<0,05), yang berarti hipotesis nol ditolak dan hipotesis alternatif diterima. Temuan ini menunjukkan bahwa latihan vertical kicking memberikan pengaruh yang signifikan terhadap peningkatan daya tahan otot tungkai atlet. Penelitian ini memberikan kontribusi praktis bagi pelatih renang dalam menyusun program latihan yang efektif untuk meningkatkan kondisi fisik dan performa atlet, khususnya pada aspek daya tahan otot tungkai. Kata Kunci: daya tahan otot tungkai, latihan fisik, pretest-posttest, renang, vertical kicking. ***** This study aimed to determine the effect of vertical kicking training on improving lower limb muscle endurance among Group III athletes of Balaena Rex Aequos Swimming Club. The research employed a quantitative approach using a quasi-experimental method with a One Group Pretest-Posttest design. The sample consisted of 20 athletes selected through a total purposive sampling. Data were collected through lower limb muscle endurance tests administered before the treatment (pretest) and after the treatment (posttest). The collected data were analyzed using descriptive statistics, the Shapiro-Wilk normality test, and the Paired Sample t-Test with the assistance of SPSS software. The descriptive analysis indicated that the mean pretest score of 48.65 increased to 89.50 in the posttest, showing an improvement of 40.85 points. The normality test yielded a significance value of 0.079 (>0.05), indicating that the data were normally distributed. Furthermore, the Paired Sample t-Test produced a significance value (Sig. 2-tailed) of 0.000 (<0.05), leading to the rejection of the null hypothesis and acceptance of the alternative hypothesis. These findings demonstrate that vertical kicking training has a significant effect on improving athletes' lower limb muscle endurance. This study provides practical contributions for swimming coaches in designing effective training programs to enhance athletes' physical condition and performance, particularly in terms of lower limb muscle endurance. Keywords: lower limb muscle endurance, physical training, pretest-posttest, swimming, vertical kicking.
