Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh metode Velocity Based Training (VBT) terhadap peningkatan daya ledak otot tungkai pada atlet taekwondo Universitas Negeri Jakarta. Penelitian ini dilatarbelakangi oleh pentingnya daya ledak otot tungkai dalam olahraga taekwondo, khususnya untuk menghasilkan tendangan yang cepat dan kuat pada sistem pertandingan modern berbasis Protector and Scoring System (PSS). Metode penelitian yang digunakan adalah metode eksperimen dengan desain One Group Pre-test Post-test Design. Populasi dalam penelitian ini berjumlah 25 atlet aktif taekwondo Universitas Negeri Jakarta dengan teknik pengambilan sampel menggunakan purposive sampling. Instrumen penelitian menggunakan tes Standing Broad Jump untuk mengukur daya ledak otot tungkai. Analisis data dilakukan melalui uji deskriptif, uji normalitas Shapiro-Wilk, dan uji hipotesis menggunakan Wilcoxon Signed Rank Test. Hasil penelitian menunjukkan adanya peningkatan nilai rata-rata Standing Broad Jump dari 197,9 cm pada pre-test menjadi 205,5 cm pada post-test. Hasil uji normalitas menunjukkan data tidak berdistribusi normal dengan nilai signifikansi < 0,05. Selanjutnya, hasil uji Wilcoxon Signed-Rank Test menunjukkan nilai signifikansi < 0,05, sehingga H₀ ditolak dan H₁ diterima. Dengan demikian, dapat disimpulkan bahwa metode Velocity Based Training (VBT) memberikan pengaruh yang signifikan terhadap peningkatan daya ledak otot tungkai pada atlet taekwondo Universitas Negeri Jakarta. ***** This study aimed to determine the effect of the Velocity Based Training (VBT) method on improving lower limb muscle power in taekwondo athletes at Universitas Negeri Jakarta. This research was motivated by the importance of lower limb muscle power in taekwondo, particularly in producing fast and powerful kicks within the modern competition system based on the Protector and Scoring System (PSS). The research employed an experimental method using a One Group Pre-test Post-test Design. The population consisted of 20 active taekwondo athletes from Universitas Negeri Jakarta, selected through purposive sampling techniques. The research instrument used was the Standing Broad Jump test to measure lower limb muscle power. Data analysis was conducted using descriptive analysis, the Shapiro-Wilk normality test, and hypothesis testing using the Wilcoxon Signed Rank Test. The results showed an increase in the average Standing Broad Jump score from 197.9 cm in the pre-test to 205.5 cm in the post-test. The normality test results indicated that the data were not normally distributed, with a significance value of < 0.05. Furthermore, the Wilcoxon Signed Rank Test showed a significance value of < 0.05, indicating that H₀ was rejected and H₁ was accepted. Therefore, it can be concluded that the Velocity Based Training (VBT) method had a significant effect on improving lower limb muscle power in taekwondo athletes at Universitas Negeri Jakarta.
