Abstract

Permainan bola voli merupakan olahraga intensitas tinggi karena terdapat loncatan, sprint pendek, dan gerakan eksplosif lainnya yang dapat mengakibatkan kelelahan. Kelelahan disebabkan oleh produksi asam laktat berlebihan pada otot karena metabolisme anerobik. Kulit terong ungu  (Solanum melongena, L.) memiliki kadar antosianin tinggi yang dapat mempercepat proses pemulihan sehabis olahraga. Dengan demikian, tujuan penelitian ini adalah mengetahui efek pemberian sport drink dengan penambahan kulit terong ungu (Solanum melongena, L.) terhadap kadar asam laktat atlet voli. Penelitian ini merupakan penelitian quasi experiment dengan desain pretest-posttest control group design with same subject dengan periode washout selama satu minggu. Sampel penelitian berjumlah 17 atlet. Hasil uji independent t-test menunjukkan tidak terdapat perbedaan signifikan kadar asam laktat atlet voli sesudah latihan antara kelompok kontrol dan kelompok eksperimen setelah diberikan perlakuan dengan nilai P signifikan 0,965 (p>0,05). Uji paired t-test menunjukkan tidak terdapat perbedaan signifikan kadar asam laktat atlet voli antara kelompok kontrol dan kelompok eksperimen sebelum dan sesudah diberikan perlakuan dengan nilai P signifikan 0,088 dan 0,101 (p>0,05).

Abstract

Volleyball is a sport that involves intense physical activity, which has the potential to trigger oxidative stress due to an imbalance between the production of free radicals and antioxidants in the body. This imbalance can cause oxidative stress in the muscles and lead to muscle fatigue (Luthfi et al., 2023). Purple eggplant skin (Solanum melongena, L.) is known to be rich in anthocyanins, which can reduce oxidative stress and accelerate post-exercise muscle recovery. This study focused on the effects of sports drink with added eggplant skin (Solanum melongena, L.) on muscle fatigue index. This study was conducted with a quasi-experimental approach using a pretest-posttest control group design with the same subject. The research subjects consisted of 17 athletes, where the control group received a placebo and the experimental group was given sports drink with added purple eggplant skin (Solanum melongena, L.). Measurements taken in this study include body weight, height, food intake, physical activity, and muscle fatigue levels. The results of the mann whitney test showed no difference in the muscle fatigue index of volleyball athletes between the control and experimental groups after treatment with a P value of 0.326 (p>0.05). The wilcoxon test showed no difference in muscle fatigue index before and after treatment in the control group with a P value of 0.344 (p>0.05) and there was a difference in muscle fatigue index before and after treatment in the experimental group with a P value of 0.041 (p>0.05).
