Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 20 participants

• Study Completion Date: 2021-09-06

Brief Summary

The main objective of this project is to compare two recovery protocols, including nutritional and neuromuscular strategies on inmune, physiological and muscular responses.

Detailed Description

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.

Conditions

Soccer; Physical Stress; Fatigue

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: OTHER
• Blinding Strategy: SINGLE

Study Groups

Protocol I

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

Group Type: EXPERIMENTAL

Powerade©, CHP, CJ, FR, CWI

Intervention Type: 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 II

Powerade@ Carbohydrates+Protein Stretching Intermittent Cold-Water Immersion

Group Type: EXPERIMENTAL

Powerade©, CHP, STR, ICWI

Intervention Type: 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.
