This study aims to analyze and prove the effect of curcumin on pain intensity and ROM during EIMD. This experimental study used a pre and post-control group design. Research subjects were selected using a purposive sampling technique and then the subjects were divided into 2 groups, namely the group given a placebo and the group was given curcumin at a dose of 400 mg. A total of 24 healthy men aged between 20-30 years participated in this study. On the first day, all subjects took data on the characteristics of research subjects, then warmed up. Then the subjects did the high-intensity physical exercise in the form of squad and leg press exercises with an intensity of 80-90% of maximum ability. The exercise was carried out in 4 sets for each form of exercise and rest between sets for about 1 minute. On the second day, after 24 hours the subject took pre-test data to measure pain intensity and ROM, then the intervention was given based on each group. On the third day, after 24 hours the subject took post-test data to measure pain intensity and ROM. Measurement of pain intensity using the Visual Analytical Scale (VAS) and measurement of ROM performed in the knee joint using a goniometer. After the data was obtained, the data were analyzed using the IBM SPSS version 26 application. The results of this study reported that the group given curcumin during EIMD was able to significantly reduce pain intensity (*p<0.05) compared to the group given a placebo. Furthermore, the group given curcumin during EIMD was able to increase ROM significantly (*p<0.05) compared to the placebo group. We believe that the main cause of muscle soreness is the uncontrolled increase in pro-inflammatory cytokines such as TNF-a and IL-6 during EIMD and then decreased ROM for several days after exercise. Since pain intensity and ROM are needed to support body functions, we highly recommend the use of curcumin, which has many positive benefits for sports enthusiasts to support physical performance.

This research aims to study how the learning planning and implementation of Physical Education, Sports, and Health learning can be used as evaluation material to improve Physical Education, Sports, and Health learning in schools. This research is action research with qualitative and quantitative descriptive methods using models from Kemmis and Mc. Taggart consists of one cycle or a round of activities which include: -1) Planning (plan), (2) Action (action), (3) Observation (observing), (4) Reflection (reflecting), and planning revision will be carried out cycle. Data processing is done by reducing data, presenting data, and making conclusions. The study results indicate that the planning and implementation aspects of academic supervision improve performance in developing learning devices and on the implementation aspects. From the results of the study, there were the findings of teacher performance not following the action in the field, such as the brakes that still copied paste from fellow teachers, the facilities were inadequate and had sports outside the school because the school was still new and did not have sports facilities, the clock of the faded subjects in SMK only 2 hours of lessons run out on a trip from school to the sport. The conclusion in this study is that after being done through the filling of teacher performance appraisal instruments given to physical education teachers, it can be obtained from cycle I to cycle II the results of better teacher educators after being given assistance and supervision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
