The purpose of this study was to investigate the effect of amino acid complex supplementation before exercise on physiological parameters. Physiological parameters are as follows :
-total exercise time
-blood lactate concentration
-lactate recovery rate
-VO2
Nine healthy - male college students ware participated in this study and maximally exercised to determine the AT of each subjects. The amino acid complex and placebo (wheat flour) was ingested in two equal oral doses of 38.5 mg/kg body weight at 60 min and 15min before the onset of exercise.
The subject continuously exercised on a bicycle ergometer with an exercise intensity of determined AT level until exhaustion.
Blood samples ware collected from finger-tip at rest, during exercise and recovery for blood lactate concentration, Heart rates and VO2 ware recorded throughout the exercise with ECG (Q-5000) and auto-respiratory gas analyzer respectively.
In both groups, no significant was found total exercise time, lactate recovery rate, VO2 However it tended to be faster and higher with amino acid complex supplementation group compare to placebo group in lactate recovery rate and VO2.
In conclusion, it suggest that the ingestion of amino acid complex supplementation before exercise may have not positive effects on physical performance by reducing the peripheral fatigue caused by accumulation of lactic acid.
