The samples will be randomly assigned to two groups using the Stratified Permuted Block Randomization method with 6 blocks of 4. In this method, A will represent group one (foam rolling group) and B will represent group two (control group). In this way, the order of interventions A and B in the form of blocks from number 1 to 6 will be determined by the project's methodological consultant and provided to the project's executive supervisor, and the researcher will obtain assignments from the executive supervisor to assign each eligible person. The executive supervisor first selects the block using a table of random numbers, and then the eligible people are assigned to one of the two groups A or B based on the order previously determined in the table, Blinding description: The outcome assessor will be blinded to the treatment groups. N/A Delayed Onset Muscle Soreness. Intervention 1: Intervention group: First, the variables are assessed and then the participants will perform the desired eccentric exercises. Based on the protocol mentioned in the Mendiguchia et al (2020) study, Nordic hamstring exercise involves eccentric contractions and will cause muscle pain. Nordic exercise consists of 5 sets of 8 repetitions, with 10 seconds of rest between repetitions and 2 to 3 seconds of rest between sets. After performing Nordic exercises, they used a foam roller. In this way, they put their maximum body weight on the foam roller and slid their body mass along it, starting from the proximal part of the back area at the hamstring muscle, then moving down and gradually moving them towards the knee, and when the foam rolling reached the distal thigh area, they returned it to the initial position. These steps were performed at a rotation speed of 30 revolutions per minute and foam rolling was performed in 4 sets of 45 seconds, with a 15-second rest between sets. In the second and third sessions, which will be 24 and 48 hours after the initial Nordic exercises, the foam rolling steps will be repeated. In order to follow up on the effect 72 hours after the Nordic exercises, a final evaluation of the variables will be performed. The evaluation and performance of the ultrasound test with shear wave was performed in collaboration with a radiologist, and the results of the evaluation before, after the first session, and 72 hours after the exercises will be recorded. The evaluation of the pressure pain and jump length variables will be performed by the first researcher in an environment close to the ultrasound location. Intervention 2: Control group: First, the variables will be evaluated and then the participants will perform the desired eccentric exercises. Based on the protocol mentioned in the Mendiguchia et al (2020) study, the Nordic hamstring exercise will include eccentric contractions and will cause muscle pain. The Nordic exercise will consist of 5 sets of 8 repetitions, with 10 seconds of rest between repetitions and 2 to 3 seconds of rest between sets. In the first session, the control group will not receive treatment after performing the exercises. In order to follow up on the effect 72 hours after performing the Nordic exercises, a final evaluation of the variables will be performed. The evaluation and performance of the ultrasound test with shear wave will be performed in collaboration with a radiologist and the results of the evaluation before, after the first session and 72 hours after the exercises will be recorded. The evaluation of the pressure pain variables and jump length will be performed by the first researcher in an environment close to the ultrasound location.
