The first objective of this research is to investigate the effectiveness of sport massage and cold water immersion in the post-exercise fatigue recovery of the PPLP sprinter athletes. Second, to determine the effectiveness of sports massage and cold water immersion in reducing post-exercise stress levels of the PPLP sprinter athletes. This research used an experimental method with a pretest-posttest-control group design. The research population was PPLP Bogor 100m sprint athletes, totaling 30 athletes and they were divided into 3 treatment groups: Sport Massage, Cold Water Immersion, and Control. The sampling technique was random sampling with certain criteria. The three groups received an exercise simulation with a duration of 60 minutes divided into 10 minutes of warm up, 45 minutes of exercise, and 5 minutes of cooling down. Before and after the treatment, pretest and posttest were conducted including the level of fatigue recovery (pulse rate, RPE, FAS) and post exercise stress level (Daily Wellness Questionnaire). The normality test used Shapiro Wilks and the data homogeneity test referred to the Levene test. Testing the effectiveness used one way ANOVA for normally distributed data and for the data that was not normally distributed using the Kruskal Wallis test. The data was then processed by using the statistical program SPSS 22. The results show that (1) there are differences in the effectiveness of sport massage and cold water immersion towards the level of post-exercise fatigue of PPLP sprinters. There are differences in treatment effectiveness between the three groups (p 0.05). Hence, in recovering post-exercise fatigue, sports massage or cold water immersion recovery techniques can be used according to the needs of athletes compared to passive rest.
