OBJECTIVES: Purpose of this study is to research the effects of acute L-Carnitine intake on badminton players' metabolic and blood lactate values. DESIGN: A total of 16 Turkish national badminton players (8 male, 8 female) were voluntarily participated into study. MaxVO2, MET, energy consumption, HR (heart rate), VE (minute ventilation), R (respiratory exchange ratio), AT (anaerobic threshold), oxygen pulse and blood lactate (LA) of subjects were measured by Sensormedics VmaxST and Accutrend Lactate Analyzer. The participants were subjected to the test protocol twice before and after 2g of L-Carnitine intake. The data were evaluated by the use of SPSS 13.0 for Windows. RESULTS: No significant differences were found between 1st. (without L-Carnitine intake) and 2nd. (with L-Carnitine intake) measurements of female participants as regards to all measured parameters. There was a significant difference in EMHR (exercise maximum heart rate) of males between two measurements (p<0.05). However the differences in other parameters were not significant. AT values of female subjects were not significant difference (p>0.05). Respiratory exchange ratio of males was significantly different at anaerobic threshold (p<0.05). CONCLUSION: Results of this study show that L-carnitine intake one hour prior to the exercise has no effect on the metabolic and blood lactate values of badminton players. |
