Outcome Measures

Primary Outcomes (6)

• Neuromuscular or physical performance measures change: jump height

  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.

  Baseline, Immediately after intervention, 24 hours after intervention, 48 hours after intervention, 72 hours after intervention

• Neuromuscular or physical performance measures change: maximal voluntary isometric contraction (MVIC)

  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).

Study Arms (2)

Protocol I

EXPERIMENTAL

Powerade© Carbohydrates+Protein Cherry Juice Foam Roller Cold Water Immersion

Other: Powerade©, CHP, CJ, FR, CWI

Protocol II

EXPERIMENTAL

Powerade@ Carbohydrates+Protein Stretching Intermittent Cold-Water Immersion

Other: Powerade©, CHP, STR, ICWI

Interventions

Powerade©, CHP, CJ, FR, CWI OTHER

Combination of recovery strategies including dietary, neuromuscular and physiological as follows: Powerade©: players will drink 500 mL during the game Carbohydrate and protein (CHP): players will drink 250 mL of water with CHP within 30 minutes after the end of the game. Tart cherry concentrate (CJ): players will drink 30 mL of CJ within 30 minutes after the end of the game. Foam roller (FR): players will follow FR protocol using a polyvinylchloride pipe roller. They will begin with the FR at the most proximal portion of the muscle and to roll as much body mass as tolerable back and forth at a cadence of 1 second superior and 1 second inferior for 45 seconds followed by a 15-second rest for each muscle group (quadriceps, adductors, hamstrings, abductors and calf) in each extremity and repeated once. Cold Water Immersion (CWI): will be the last strategy used. Players will immerse their lower body to the level of hips for 10 minutes in cold water (13-14°C).

Protocol I

Powerade©, CHP, STR, ICWI OTHER

Combination of recovery strategies including dietary, neuromuscular and physiological as follows: Powerade©: players will drink 500 mL of "Powerade©" during the game Carbohydrate and protein intake (CHP): players will drink 250 mL of water with CHP within 30 minutes after the end of the competition. Stretching (STR): players will perform 10-min of static stretching, involving 2 unilateral repetitions of 30 seconds held stretches to the quadriceps, adductors, hamstrings, abductors and calf muscles. Intermittent Cold-Water Immersion (ICWI): will be the last strategy used. It will consist of five 2 min intermittent immersions of the lower limb (up to the iliac crest) in a cold-water bath (13-14ºC), separated by 2 min rest in ambient air. Ice will be added to the bath at regular intervals to maintain water temperature at 13-14ºC. Players will be instructed to stand in the bath, with as little movement as possible.
