Akumulasi asam laktat pada sel otot akibat latihan intens dapat mengakibatkan penurunan PH otot dan darah yang menyebabkan kontraksi otot melemah sehingga mengalami kelelahan otot. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi active recovery (joging) dan foam rolling terhadap kadar asam laktat setelah lari sprint 400 meter pada anggota UKM atletik putra Universitas Negeri Surabaya. Penelitian ini dilakukan di Lapangan Atletik Oentoeng Poedjadi Universitas Negeri Surabaya, pada tanggal 24 November 2024. Penelitian ini merupakan penelitian Experimen dengan desain Randomized Control Group Pretest-Posttest Design. Terdapat 20 subjek yang memenuhi kriteria. subjek dibagi menjadi 2 kelompok setiap kelompok 10 orang secara random. Instrumen penlitian menggunakan lari sprint 400 meter dengan intensitas maksimal dan kombinasi active recovery joging dan foam rolling pada kelompok perlakuan dan recovery pasif (duduk) pada kelompok kontrol. Teknik analisis data menggunakan Uji Normalitas, Uji Wilcoxon, Dan Uji Mann- Whitney. Hasil penelitian menunjukkan terdapat pengaruh kombinasi active recovery (joging) dan foam rolling terhadap penurunan kadar asam laktat dalam darah setelah lari sprint 400 meter dengan nilai Asymp.Sig.(2-tailed) sebesar (0,005 < 0,05). Hasil uji Mann-Whitney menunjukkan nilai (0,00 < 0,05) yang dapat diartikan terdapat perbedaan yang signifikan penurunan kadar asam laktat setelah lari sprint 400 meter pada anggota UKM atletik Universitas Negeri Surabaya kelompok yang diberikan kombinasi active recovery (joging) dan foam rolling dengan kelompok recovery pasif (duduk). Dari hasil tersebut, dapat disimpulkan bahwa kombinasi recovery active joging dan foam rollig dapat dijadikan metode pemulihan yang dapat mempercepat penurunan kadar asam laktat darah dan kelelahan untuk meningkatkan performa atlet pada sesi latihan atau perlombaan.

The accumulation of lactic acid in muscle cells due to intense exercise can lead to a decrease in muscle and blood pH, causing weakened muscle contractions and resulting in muscle fatigue. This study aims to determine the effect of a combination of active recovery (jogging) and foam rolling on lactate levels after a 400-meter sprint among male members of the athletics student organization at Universitas Negeri Surabaya. This research was conducted at the Oentoeng Poedjadi Athletic Field of Universitas Negeri Surabaya on November 24, 2024. This research is an experimental study with a Randomized Control Group Pretest-Posttest Design. There are 20 subjects who meet the criteria. The subjects were divided into 2 groups, each consisting of 10 people, randomly. The research instrument used a 400-meter sprint with maximum intensity and a combination of active recovery jogging and foam rolling for the treatment group, and passive recovery (sitting) for the control group. The data analysis technique used Normality Test, Wilcoxon Test, and Mann-Whitney Test. The research results show that there is an influence of the combination of active recovery (jogging) and foam rolling on the reduction of blood lactate levels after a 400-meter sprint with an Asymp.Sig.(2-tailed) value of (0.005 < 0.05). The Mann-Whitney test results show a value of (0.00 < 0.05), which indicates a significant difference in the reduction of lactate levels after a 400-meter sprint among members of the Surabaya State University athletics student organization who were given a combination of active recovery (jogging) and foam rolling compared to the passive recovery group (sitting). From these results, it can be concluded that the combination of active recovery jogging and foam rolling can be used as a recovery method that accelerates the reduction of blood lactate levels and fatigue to improve athlete performance in training sessions or competitions.
