Abstract
ABSTRAK: Penelitian ini bertujuan untuk mengetahui pengaruh metode Contrast Bath terhadap penurunan kadar asam laktat pada Klub Olahraga Prestasi Cricket UNJ. Pengambilan data dilakukan pada bulan desember 2019 yang bertempat di nets cricket kampus B FIO UNJ. Metode penelitian yang digunakan dalam penelitian ini adalah metode eksperimen, “One Group Pre-test and Post-test Design” Dalam teknik pengambilan sampel menggunakan teknik purposive sampling yang berjumlah 15 orang dari jumlah populasi 35 orang. Pengambilan data di dahului dengan RAST Test (anaerobik tes) setelah itu langsung melaksanakan metode contrast bath. Teknik analisis data yang digunakan adalah teknik t-test (uji-t) dengan menghitung nilai t-hitung dibandingkan dengan t-tabel pada derajat kebebasan n-1 dan pada taraf signifikasi 0,05. Dari hasil penelitian mengenai penurunan kadar asam laktat pada pengaruh metode contrast bath diperoleh nilai selisih rata-rata (MD) 9,61 dengan standar deviasi perbedaan rata-rata (SDD) yaitu sebesar 0,76 dan standar error perbedaan rata-rata (SEMD) sebesar 0,2 dalam perhitungan selanjutnya diperoleh nilai t-hitung sebesar 48,05 dan nilai t-tabel sebesar 2,14 dengan demikian nilai t-hitung > dari t-tabel yang menunjukkan bahwa hipotesa nihil (H0) ditolak dan hipotesa alternatif (H1) diterima. Maka dapat disimpulkan bahwa terdapat pengaruh metode contrast bath terhadap penurunan kadar asam laktat pada anggota KOP cricket Universitas Negeri Jakarta. Kata Kunci : cricket, contrast bath, kadar asam laktat ABSTRACT: This study aims to determine the effect of the Contrast Bath method on reducing levels of lactic acid in the UNJ Cricket Performance Sports Club. Data was collected in December 2019 which took place at the B FIO UNJ campus cricket. The research method used in this study is the experimental method, "One Group Pre-test and Post-test Design" In the sampling technique using purposive sampling technique, amounting to 15 people from a total population of 35 people. Retrieval of data is preceded by an RAST Test (anaerobic test) after that immediately carry out the contrast bath method. The data analysis technique used is the t-test technique by calculating the value of t-count compared to t-table at degrees of freedom n-1 and at the significance level of 0.05. From the results of research on the decrease in levels of lactic acid on the effect of the contrast bath method obtained an average difference value (MD) of 9.61 with a standard deviation of the average difference (SDD) that is equal to 0.76 and the standard error of the average difference (SEMD) of 0.2 in the next calculation, the value of t-count is 48.05 and the value of ttable is 2.14, thus the value of t-count> of t-table shows that the null hypothesis (H0) is rejected and the alternative hypothesis (H1 ) be accepted. Then it can be concluded that there is an effect of the contrast bath method to decrease levels of lactic acid in KOP cricket members at Jakarta State University. Keywords: cricket, contrast bath, lactic acid levels
