Clinical Trial Summary

The aim of this study was to compare the effects of cold water intermittent ion (CWI), carbohydrate and protein supplementation (SUPPL), and active recovery (ACT) on creatine kinase (CK), perceptual and performance markers of recovery in elite basketball players after a specific fatigue protocol. Fifteen elite basketball players participated in this crossover controlled trial. All participants were randomly measured in 4 conditions of the recovery method 1 week apart after a fatigue exercise protocol (~ 45 'of high intensity intermittent effort with specific basketball movements). The recovery methods consist of CWI at 10oC in periods of 2 minutes submerged and 2 minutes out of the water, supplementation with 0.3gr / kg of maltodextrin and 0.2gr / kg of neutral whey protein in 0.5 liters of water, pedaling ACT for 25 minutes at 50% of maximum heart rate or a placebo drink (PLA). The Visual Analogue Fatigue Scale (VAS), Perceived Exercise Rate (RPE), CK and physical performance (jumping, speed, isometric and dynamic tests of resistance to squats) were measured before, after and 24 hours after of the protocol. The VAS scale and RPE were also measured immediately after application of the recovery method. Repeated 2-way post-hoc comparisons of ANOVA and Bonferroni measures were applied, with a significance set at P <0.05.

Related Conditions & MeSH terms

• Placebo

Intervention

Procedure:
• Cold-water immersion
Subjects were immersed, in a sitting position where legs were always covered, in cold water at 11ºC in periods of 2 minutes submerged and 2 minutes out of the water at room temperature (25ºC), repeating this process 5 times
• Protein-carbohydrates supplementation
Subjects consumed a mixed carbohydrate and protein beverage, composed of 0.3gr/kg of maltodextrin and 0.2gr/kg of neutral whey protein in 0.5 litres of water. Subject sat for 25 minutes until all recovery methods were completed.
• Active recovery
Subjects was carried out using a bicycle ergometer. The subjects pedaled for 25 minutes at 50% of the maximum heart rate (HRmax)
• Placebo
Subjects drank a water-based drink and sweetener. Subject sat for 25 minutes until all recovery methods were completed.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Creatine Kinase (CK)	Blood samples were obtained from the earlobe and collected into capillary tubes. Serum creatine kinase activity was analyzed with Reflotron ® Plus - Roche	4 Weeks
Primary	Fatigue perception	The VAS fatigue scale (VAS) was used and evaluated on a scale from 1 to 10 (1 = no fatigue and 10 = extremely fatigued).	4 Weeks
Primary	Rate of Perceived Exertion	The Rate of Perceived Exertion Scale (RPE) was used and evaluated on a scale from 1 to 10 (1 = no exertion and 10 = extremely hard).	4 Weeks
Primary	10 meters sprint time	10m Sprint Test was used and subjects ran 10m maximally. The subjects had 2 attempts to achieve their best performance with 1 minute of rest between trials. Time was recorded with a video analysis.	4 Weeks
Primary	4 x 10 meters agility time	4 x 10m Agility Test was used and subjects had to run as fast as possible between two cones 10 meters apart four times. The subjects had 2 attempts to achieve their best performance with 1 minute of rest between trials. Time was recorded with a video analysis.	4 Weeks
Primary	Squat Jump	The flight time in jumps height and its maximal speed were used as a measure of maximal muscle power and was measured on a force platform (Quattro Jump, Kristler). In squat jump, the subjects were asked to keep their hands on their hips and beginning the jump with a 90º knee flexion, without countermovement. Subjects had 2 attempts to achieve their best jump with 3 minutes of rest between trials.	4 Weeks
Primary	Counter Movement Jump	The flight time in jumps height and its maximal speed were used as a measure of maximal muscle power and was measured on a force platform (Quattro Jump, Kristler). In countermovement jump, subjects were only asked to keep their hands on their hips and jump as high as possible, with countermovement. Subjects had 2 attempts to achieve their best jump with 3 minutes of rest between trials.	4 Weeks
Primary	Abalakov Jump	The flight time in jumps height and its maximal speed were used as a measure of maximal muscle power and was measured on a force platform (Quattro Jump, Kristler). Abalakov jump was performed with free arms movement and countermovement. Subjects had 2 attempts to achieve their best jump with 3 minutes of rest between trials.	4 Weeks
Primary	Half Squat Isometric Strength	In the maximal isometric strength test, the subjects performed a maximal isometric contraction in the half squat exercise, with 90º knee flexion. The strength of the subjects was measured with a force platform on which the exercise was performed. The subjects were asked to perform the maximal strength possible since the start and to not stop until a signal. They had 2 attempts to achieve their best performance with 3 minutes of rest between trials.	4 Weeks
Primary	Half Squat Dynamic Strength	In the dynamic strength test, the subjects performed 6 repetitions of a half squat, using a Smith Machine, with the load that represented the 70% of RM (0.65 m·s) at baseline in the half squat exercise. The mean velocity was measured with a linear encoder and it was registered the fastest repetition. The subjects were asked to perform the concentric action as fast as possible. They had 2 attempts to achieve their best performance with 3 minutes of rest between trials.	4 Weeks
