Abstract

Untuk melakukan manuver lompat seperti smash dalam olahraga badminton, diperlukan kekuatan otot tungkai yang baik. Dalam pengembangan strategi, mental, taktik, dan teknik, kekuatan memainkan peran fisik yang krusial. Latihan yang mampu meningkatkan kekuatan otot tungkai yakni plyometrik dengan cara: box jump, box shuffle serta squat jump. Penelitian ditujukan guna mengetahui apakah program latihan box jump, box shuffle, serta squat jump berpengaruh pada atlet UKM Badminton Universitas Negeri Malang. Penelitian ini memiliki sifat pre-eksperimental dengan memakai One Group Pretest-Posttest Design. Penelitian yang dilakukan juga memakai 15 atlet sebagai subjek, dan program latihan, dengan rincian waktu tiga kali per minggu selama 18 kali pertemuan. Hasil membuktikan terdapat nilai signifikan 0,001<0,05, dengan memakai uji paired sample t-test, berarti ada pengaruh signifikan dari treatment yang telah diberikan, jika nilai signifikasi (<0,05) maka hipotesis bisa diterima. Berlandaskan hasil penelitian, simpulan akhir memperlihatkan bahwa perlakuan yang diberi mempunyai pengaruh terhadap kekuatan otot tungkai pada Atlet UKM Badminton UM. Kata Kunci: Badminton, kekuatan otot tungkai, latihan plyometrik: box jump, box shuffle, dan squat jump.

Abstract

This study aims to determine the extent of the effect of L-Arginine amino acid supplementation on oxygen saturation and lactic acid levels at the fitness level (VO2Max) of West Kalimantan muaythai athletes. High lactic acid levels can be an indicator of fatigue in athletes after undergoing a physical fitness test. This type of quantitative descriptive research used a randomized group pretest-posttest group design sampling method. The subjects in the study used were male athletes on the West Kalimantan Muaythai team who will be prepared for the 2024 International Student Muaythai Championship. In this study, the subjects were divided into two groups, the first group was given a placebo and the second group was given the amino acid L-arginine. Each group was given the same treatment, namely a physical fitness test to determine the VO2Max level using a bleep test. Before and after carrying out the physical fitness test, the subjects were checked for oxygen saturation, and blood lactic acid samples were taken. The results showed that L-Arginine supplementation had a positive effect in helping to maintain optimal oxygen saturation in the body and reducing the accumulation of blood lactic acid levels that can cause fatigue in Muay Thai athletes. This shows the significant role of L-arginine supplementation in helping to enhance physical endurance performance and speed up recovery during and after physical activity.
