Effects on CK, RPE, VAS Scale and Physical Performance of Three Recovery Methods in Elite Basketball Players

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.

• Active Recovery
• Placebo

Interventions

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

PROCEDURE

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.

PROCEDURE

Active recovery

Subjects was carried out using a bicycle ergometer. The subjects pedaled for 25 minutes at 50% of the maximum heart rate (HRmax)

PROCEDURE

Placebo

Subjects drank a water-based drink and sweetener. Subject sat for 25 minutes until all recovery methods were completed.
