The purpose of this study was to investigate the effects of amino acid drink which contains so much the branch chain amino acid on physical activity during aerobic exercise in college students. As a results, the amount of maximum oxygen uptake during exercise showed the low value compared with other drinks by amino acid drink ingestion. It was admitted that the increasing rate of the blood lactic acid concentration immediately after movement was stopped with the drinking of an amino acid drink before exercise. The rate of perceptive exertion showed the lower value by amino acid drink ingestion compared with other drinks. In conclusion, it was suggested that amino acid drink ingestion before the exercise was expected effects such as improvement in movement efficiency, control of" blood lactate acid concentration and mitigation of fatigue.

Physiological effect of L-arabitol was investigated by feeding Sprague-Dawley male rats for four weeks with a diet containing 2.5% L-arabitol in comparison with the control diet, containing cellulose. The weights of kidney and cecum increased, while adipose tissue decreased significantly in spite of no difference in their body weights.
