This study aims to analyze the potential of rhodiola rosea in reducing muscle pain and increasing ROM during EIMD. This experimental research uses a pre- and post-control group design. Research subjects were selected using a purposive sampling technique, then the subjects were divided into 2 groups, namely group (K1) which was given placebo and group (K2) which was given rhodiola rosea at a dose of 500 mg. A total of 18 healthy men aged between 19-25 years participated in this study. Data collection began on the first day by collecting data on subject characteristics. After that, they were asked to warm up. Physical activity is carried out afterward. These activities include high-intensity activities, such as walking lunges, good mornings, and leg extensions. This exercise is done in 4 sets with a 1-minute break (recovery) between sets. Exercise intensity is monitored using a Polar H9 Heart Rate Sensor. On day 2 or 24 hours after training, subjects took pre-test data to measure muscle soreness and ROM. Subjects were then given placebo or rhodiola rosea treatment, depending on the group assigned. On the 3rd day or 48 hours after training, post-test data was collected again. Muscle intensity was measured using a Visual Analog Scale (VAS) and ROM was measured at 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 K1 group given placebo did not significantly reduce muscle pain and increase ROM during EIMD, while the K2 group given rhodiola rosea at a dose of 500 mg significantly reduced pain. muscle and increase ROM during EIMD. Considering that pain management and ROM are very necessary to support body function, we recommend the use of rhodiola rosea for sports enthusiasts to support physical performance.
