Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi Proprioceptive Neuromuscular Facilitation (PNF) dan foam roller terhadap penurunan kadar asam laktat pada atlet Perguruan Pencak Silat Balya. Metode penelitian pada penelitian ini adalah Quasi Expremental Design dengan rancangan Nonequivalet Control Grup Design yang melibatkan dua kelompok. Sampel terdiri dari 16 atlet yang dibagi menjadi dua kelompok, yaitu kelompok treatment dan kelompok kontrol. perlakuan diberikan satu kali dengan waktu 40 menit ,dan kadar asam laktat diukur sebelum dan sesudah perlakuan. Hasil penelitian menunjukkan adanya penurunan kadar asam laktat yang signifikan baik pada kelompok treatment maupun kelompok kontrol, berdasarkan hasil uji Paired Sample t-Test. Pada kelompok treatment, rata-rata penurunan kadar asam laktat mencapai 7,450 mmol/L dengan nilai signifikansi 0.000231. Sementara itu, kelompok kontrol menunjukkan rata-rata penurunan sebesar 4,000 mmol/L dengan signifikansi 0,001. Selanjutnya, hasil analisis menggunakan Independent Sample t-Test menunjukkan bahwa penurunan kadar asam laktat pada kelompok treatment lebih signifikan dibandingkan kelompok kontrol, dengan nilai t = 3,51 mean difference sebesar 3,450, dan nilai signifikansi p = 0,006. Hal ini menunjukkan bahwa kombinasi Proprioceptive Neuromuscular Facilitation (PNF) dan foam roller efektif dalam mempercepat proses eliminasi asam laktat setelah melakukan aktivitas fisik dengan intensitas tinggi. ***** This study aims to determine the effect of the combination of Proprioceptive Neuromuscular Facilitation (PNF) and foam roller on reducing lactic acid levels in athletes of the Balya Pencak Silat School. The research method in this study is Quasi Experimental Design with a Nonequivalet Control Group Design involving two groups. The sample consisted of 16 athletes divided into two groups, namely the treatment group and the control group. The treatment was given once with a time of 40 minutes, and lactic acid levels were measured before and after treatment. The results showed a significant decrease in lactic acid levels in both the treatment and control groups, based on the results of the Paired Sample t-Test. In the treatment group, the average decrease in lactic acid levels reached 7.450 mmol/L with a significance value of 0.000231. Meanwhile, the control group showed an average decrease of 4.000 mmol/L with a significance value of 0.001. Furthermore, the results of the analysis using the Independent Sample t-Test showed that the decrease in lactic acid levels in the treatment group was more significant than the control group, with a t value = 3,51, a mean difference of 3.450 , and a significance value of p = 0.006. This indicates that the combination of Proprioceptive Neuromuscular Facilitation (PNF) and foam roller is effective in accelerating the process of lactic acid elimination after high-intensity physical activity.
