简要总结
The main objective of this project is to compare two recovery protocols, including nutritional and neuromuscular strategies on inmune, physiological and muscular responses.
详细描述
A randomized controlled trial will be performed and players will be assigned in one of the two groups after their participation in a football game. The investigators will take baseline measures before the game and post-competition measures immediately after (after recovery intervention) and at 24, 36, 48 hours after the recovery intervention.

结局指标
主要结局
Neuromuscular or physical performance measures change: jump height
时间窗: Baseline, Immediately after intervention, 24 hours after intervention, 48 hours after intervention, 72 hours after intervention
Counter Movement Jump (CMJ) will be performed to determine the maximum height in centimeters (cm). From standing position with the hands fixed on the hips, participants will be required to bend their knees to a freely chosen angle and perform a maximal vertical jump. Participants will be instructed to keep their body vertical throughout the jump, and to land with knees fully extended. Any jump that will be perceived to deviate from the required instructions will be repeated. Players will jump 3 times as high as possible and the average of the three jumps will be used in subsequent analysis. A 30-s passive recovery phase will be provided between jumps.
Neuromuscular or physical performance measures change: maximal voluntary isometric contraction (MVIC)
时间窗: Baseline, Immediately after intervention, 24 hours after intervention, 48 hours after intervention, 72 hours after intervention
Isometric Hamstring Strength (IHS). Players will be in a supine position, with the tested leg strapped around the ankle (in a neutral position) and performed a hip extension (with a slight knee flexion 20º, while the non-dominant leg was resting on the floor). Players will place their hands on the wall to avoid sliding on the floor. A strain gauge will be placed between the ankle strap and the cord to evaluate the force (MVIC) exerted at a sampling frequency of 80Hz (Chronojump, Boscosystem®️, Barcelona, Spain). The tester will give all participants the same instructions; "to exert maximal force down to the floor" and continuous and standardized verbal motivation for 5 seconds. Each limb will be tested 3 times, in a randomized order. The assessment of both legs will be separated by 30 seconds while the time separating two trials of the same leg will be 60 seconds . The MVIC will be tested and measured in Newtons (N).
Biochemical/Physiological measures change: urea
时间窗: Baseline, Immediately after intervention, 24 hours after intervention, 48 hours after intervention, 72 hours after intervention
Urea: umol/L or mg/dL
Biochemical/Physiological measures change: mioglobin
时间窗: Baseline, Immediately after intervention, 24 hours after intervention, 48 hours after intervention, 72 hours after intervention
Mioglobin: n/mol/L
Biochemical/Physiological measures change: ions
时间窗: Baseline, Immediately after intervention, 24 hours after intervention, 48 hours after intervention, 72 hours after intervention

时间窗: Baseline, Immediately after intervention, 24 hours after intervention, 48 hours after intervention, 72 hours after intervention
Creatine Kinase (CK): units/L
