Effects of albumin and carnitine ingestion on energy metabolism variables and fat oxidation during exercise ofmaximal fat oxidation exercise intensity

ABSTRACT

Effects of albumin and carnitine ingestion on energy metabolism variables and fat oxidation during exercise of maximal fat oxidation exercise intensity. Exercise Science, 13(4): 493-504, 2004. The purpose of this study was to examine the effects of albumin and carnitine ingestion on energy metabolism variables and fat oxidation during exercise of maximal fat oxidation exercise intensity following three different treatments methods(placebo[PL], albumin[AB] and carnitine[CR] ingestion). Subjects of this study were consisted of ten healthy active male college students(18.6±0.8 yaers) who were majoring physical education.. The submaximal exercise intensity of this study was the maximal fat oxidation exercise intensity(MFOEI; 26.9±0.8㎖/kg/min) of subjects which was determinated during graded maximal exercise test on the treadmill(Bruce protocol). To comparative analysis on the effect of energy metabolism during submaximal exercise(300kcal) after ingestion of albumin and carnitine it was compared the energy metabolic variables included VO2, RER, fat oxidation rate(%Fat) and fat kilocalories(Fkcal). The both three treatments, there was significant difference among the measurement times included resting, during exercise and every period of recovery in VO2, RER, %Fat and Fkcal, and significant difference between PL, CR and AB treatment methods. Especially, after CR treatment, there were significant difference in 5, 10, 30 and 60min recovery periods in comparison with other treatment methods.In summary, results of this study revealed that albumin and carnitine have the beneficial effects on energy metabolism activity and fat oxidation facilitation by increased VO2 and decreased RER. Especially, CR treatment method has the greater effect on fat metabolism.
