Abstract
Abstract
The aim of this study was to examine the effect of caffeine supplementation on aerobic, lactic anaerobic and alactic anaerobic performances in male futsal plyers following a simulated futsal match.
Methods: Twenty trained futsal players (age= 34.05±3.7 yr., weight=74.38±8.65 kg, height= 1.75± 4.3 cm, body fat%=20.82±5.6 and BMI=24.15±2.62 kg/m2) participated in this single group, placebo controlled and single blinded study. The participants conducted tow simulated futsal games with 1 week break between them after ingesting either caffeine (3mg/kg body mass) or placebo. The subjects consumed the same food 24 hr. before each protocol protocol. At the baseline and immediately after tow protocols, alactic anaerobic, lactic anaerobic, and aerobic performances were assessed using Sargent jump test, Running based anaerobic sprint (RAST) test and 5 minutes running field test as a measurement of maximal aerobic velocity, respectively. The data were analyzed using repeated measures of analysis of variance.
Results: After futsal simulation under caffeine or placebo condition, There were no significant (p≥0.05) differences on alactic anaerobic performance compared to baseline, and alactic anaerobic power output was not significantly(p≥0.05) different between tow conditions after simulated protocol. After futsal simulation, aerobic and lactic anaerobic performances for caffeine and placebo conditions were significantly (p≤0.05) lower that the baseline. Post protocol aerobic and lactic anaerobic performance measures were found significantly (p≤0.05) higher in the caffeine condition than that of in the placebo.
Conclusions: Based on these results it can be said that 3 mg/kg body mass acute caffeine supplementation retards aerobic and lactic anaerobic performances decline after simulated futsal protocol. But it is not clear whether these ergogenic effects influence performance during futsal game. Therefore the results need to be confirmed during simulated and true futsal games.
