Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas pemberian 500 ml jus semangka murni terhadap penurunan Delayed Onset Muscle Soreness (DOMS) pada atlet Taekwondo. Menggunakan metode Eksperimen dengan Pretest-Posttest Control Group Design, sebanyak 20 atlet dibagi menjadi kelompok eksperimen dan kelompok kontrol. Induksi DOMS dilakukan melalui latihan pliometrik, dan tingkat nyeri diukur menggunakan Numeric Rating Scale (NRS) sebelum latihan, 24 jam, dan 48 jam pasca-latihan. Analisis data menggunakan Wilcoxon Signed Rank Test dan Mann-Whitney U Test. Hasil penelitian menunjukkan penurunan tingkat DOMS yang signifikan pada kelompok eksperimen dibandingkan kelompok kontrol (p=0,000), dengan rata-rata skor NRS yang lebih rendah pada kelompok eksperimen (4,10 di 24 jam; 2,00 di 48 jam). Disimpulkan bahwa konsumsi 500 ml jus semangka segera setelah latihan efektif menurunkan intensitas DOMS pada atlet, sehingga disarankan sebagai strategi pemulihan alami pasca-latihan intensitas tinggi. ***** This study aims to analyze the effectiveness of administering 500 ml of pure watermelon juice on reducing Delayed Onset Muscle Soreness (DOMS) in Taekwondo athletes. Using the Experimental method with Pretest-Posttest Control Group Design, 20 athletes were divided into an experimental group and a control group. DOMS induction was carried out through plyometric training, and pain levels were measured using the Numeric Rating Scale (NRS) before training, 24 hours, and 48 hours post-training. Data analysis used the Wilcoxon Signed Rank Test and the Mann-Whitney U Test. The results showed a significant decrease in DOMS levels in the experimental group compared to the control group (p = 0.000), with a lower average NRS score in the experimental group (4.10 at 24 hours; 2.00 at 48 hours). It was concluded that consuming 500 ml of watermelon juice immediately after training effectively reduces the intensity of DOMS in athletes, thus it is recommended as a natural recovery strategy after high-intensity training.
