Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh metode slow jogging, asupan protein, dan relaksasi terhadap penurunan kadar asam laktat pada atlet taekwondo junior. Penelitian menggunakan pendekatan kuantitatif dengan desain quasi experiment (pretest-posttest). Sampel terdiri dari 36 atlet yang dibagi menjadi tiga kelompok perlakuan. Masing-masing kelompok menjalani intervensi berbeda selama 20 menit, yaitu slow jogging, asupan protein, dan relaksasi, setelah melakukan aktivitas fisik intensif. Pengukuran kadar asam laktat dilakukan sebelum dan sesudah perlakuan. Hasil menunjukkan bahwa ketiga metode efektif menurunkan kadar asam laktat, namun slow jogging memberikan hasil paling signifikan, diikuti oleh asupan protein, dan terakhir relaksasi. Temuan ini menunjukkan bahwa pemulihan aktif seperti slow jogging lebih optimal dalam mengurangi kelelahan otot dibandingkan pemulihan pasif. Dengan demikian, slow jogging direkomendasikan sebagai metode pemulihan utama bagi atlet taekwondo junior. Hasil ini didapat dari perhitungan menggunakan software IBM SPSS 25 ********* This study aimed to determine the effect of slow jogging, protein intake, and relaxation on reducing lactic acid levels in junior taekwondo athletes. The study used a quantitative approach with a quasi-experimental design (pretest-posttest). The sample consisted of 36 athletes divided into three treatment groups. Each group underwent a different 20-minute intervention: slow jogging, protein intake, and relaxation, after intensive physical activity. Lactic acid levels were measured before and after the treatment. The results showed that all three methods were effective in reducing lactic acid levels, but slow jogging provided the most significant results, followed by protein intake, and finally, relaxation. These findings suggest that active recovery, such as slow jogging, is more optimal in reducing muscle fatigue than passive recovery. Therefore, slow jogging is recommended as the primary recovery method for junior taekwondo athletes. These results were obtained from calculations using IBM SPSS 25 software. Keywords: slow jogging, protein intake, relaxation, lactic acid, taekwondo.
