Training is a form of physical exercise that can improve physical fitness if done with correct frequency and intensity. Regular and measured training requires various training programs, such as interval training, circuit training, continuous training, combination training/exercise, or weight exercise, each of which has measurable exercise ratio to individual needs. Regular and measured training will result in increased work of respiratory system, cardiovascular system, strengthen skeletal muscles and endurance. The purpose of this research is to analyze the effect of exercise ratio 1:2 on changes of anaerobic threshold and lactate acid level in students of Physical Education, Health, and Recreation Study Program, Sport Education Department, Faculty of Sport Sciences, Universitas Negeri Yogyakarta (PJKR FIK UNY). Research method used was by quasi-experimental. Research design applied pretestposttest group design, with quantitative research type. Data collection for the variables studied was done by test instrument anaerobic threshold test using Fitmate version 2.2, Wellness Technology a Division of Cosmed and treadmill, lactate acid level test using Accutrend Plus. Research results indicate that they are three conclusions; the first eexercise ratio 1:2 gives significant effect on anaerobic threshold changes of PJKR FIK UNY students. The second, eexercise ratio 1:2 gives significant effect on lactate acid level changes of PJKR FIK UNY students. The third, exercise ratio 1:2 gives significant effect on changes of anaerobic treashold and lactate acid level of PJKR FIK UNY students. © 2019 Annals of Tropical Medicine & Public Health.
