Abstract

ABSTRAK Asam laktat merupakan zat yang tertimbun di dalam tubuh setelah melakukan aktifitas dengan intensitas tinggi yang diakibatkan oleh system energi anaerob. Berdasarkan beberapa studi sebelumnya, penumpukan asam laktat setelah latihan secara efektif dapat diturunkan melalui metode active recovery. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh active recovery terhadap kadar asam laktat pada mahasiswa Program Studi llmu Keolahragaan Universitas Negeri Jakarta. Penelitian ini menggunakan metode eksperimen dengan one grup pre and post test design. Sampel penelitian berjumlah 10 orang yang akan didapat melalui teknik purposive sampling. Penelitian dilaksanakan di Gelanggang Olahraga Rawamangun dan Kampus B UNJ di Jakarta Timur pada bulan April hingga November tahun 2019. Berdasarkan hasil penelitian terdapat pengaruh active recovery terhadap kadar asam laktat pada mahasiswa Program Studi llmu Keolahragaan Universitas Negeri Jakarta. Kata kunci: Active Recovery dan Asam Laktat ABSTRACT Lactic acid is a substance that is deposited in the body after carrying out activities with high intensity caused by the anaerobic energy system. Based on several previous studies, lactic acid buildup after exercise can effectively be reduced through active recovery methods. The purpose of this study was to determine the effect of active recovery on lactic acid levels in students of the Sport science at the State University of Jakarta. This study uses an experimental method with one group pre and post test design. The research sample of 10 people who will be obtained through purposive sampling technique. The research was conducted at the Rawamangun Sports Center and Campus B UNJ in East Jakarta from April to November 2019. Based on the results of the study there was an effect of active recovery on lactic acid levels in students of the sport Science Program at the State University of Jakarta. Keywords: Active Recovery and Lactic Acid

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh latihan plyometric depth jump terhadap daya ledak otot tungkai dan kadar enzim keratinfosokinase (CPK) pada atlet basket. Latihan plyometric depth jump adalah tipe latihan yang predominan metabolisme anaerobik yang dilakukan dalam intensitas tinggi sehingga dapat menimbulkan cedera pada sel otot. Metode penelitian ini adalah eksperimental dengan subjek penelitian 22 atlet bola basket putra dengan rata-rata usia 19 tahun selama 6 minggu. Sebelum pemberian latihan dilakukan pengukuran daya ledak otot tungkai dan kadar (CPK) diukur 24 jam setelah melakukan latihan pertama. Hasil penelitian menunjukkan peningkatan daya ledak otot tungkai (54,05±5,00 vs 58,32±4,17 p=0,00) sebesar 9,56% dan penurunan kadar CPK (626,32±506,98 vs 260,68 ±155,02 p=0,00) sebesar 27,88% setelah melakukan latihan plyometic depth jump selama 6 minggu. Simpulan penelitian menunjukkan bahwa latihan plyometric depth jump meningkatkan daya ledak otot tungkai dan menurunkan kadar CPK pada pemain bola basket setelah melakukan latihan selama 6 minggu. Kata Kunci: Plyometrik Depth Jump, Daya Ledak Otot Tungkai, Enzim Keratinfosokinase (CPK) ABSTRACT This study aims to find out effect of plyometric depth jump exercises on the explosive power of the limb muscles and levels of the enzyme keratinfosokinase in basketball athletes Plyometric depth jump exercises are types of exercises that predominant anaerobic metabolism performed in high intensity so as to cause injury to muscle cells.This research method was experimental with the study subjects of 22 male basketball athletes with an average age of 19 years a 6-week plyometric depth jump exercise. Prior to the administration of exercise, measurements of limb muscle explosives and keratinfosokinase (CPK) enzyme levels were measured 24 hours after the first exercise. The results showed an increase in the explosive power of the limb muscles (54.05±5.00 vs. 58.32±4.17 p=0.00) by 9.56% and a decrease in CPK levels (6 26.32±506.98 vs 260.68 ±155.02 p=0.00) by 27.88% after doing plyometic depth jump exercises for 6 weeks.The study concluded that plyometric depth jump exercises increase the explosiveness of the limb muscles and lower CPK levels in basketball players after 6 weeks of exercise. Keywords: Plyometric Depth Jump, Limb Muscle Explosive Power, Enzyme Keratinfosokinase (CPK)
