      <i_freetext>Intervention 1: First intervention group: First, pre-test measurements will be conducted on all subjects, which include delayed onset muscle soreness, lower body strength, flexibility, lower body static strength, and speed. Then, the subjects will play a friendly soccer match in the form of two teams in compliance with all FIFA standards in two 45-minute halves with a 15-minute break between the halves. After the competition, the subjects will be divided into two groups of cold-water immersion and contrast water therapy to implement recovery protocols. The cold-water immersion group will completely immerse in 15°C water without moving for 15 minutes from the neck to the soles of the feet. After that, the post-test measurements will be performed in the same conditions as the pre-test in 1, 24 and 48 hours after the recovery protocol. Intervention 2: Intervention group: After the completion of the match, the other half of the subject will receive the contrast water therapy intervention. The intervention includes immersion in hot water, 38°C, for 2 minutes and then immersion in cold water, 15°C, for two minutes alternatively and the process will be repeated 4 times with 1 min rest in between. After that, the post-test measurements will be performed in the same conditions as the pre-test in 1, 24 and 48 hours after the recovery protocol.</i_freetext>
