| Research Abstract |
The purpose of this study was to examine 1) circadian variations of sulfoconjugated catecholamines (CA-S) in normal subjects, 2) the effect of diet, smoking and exercise on CA-S concentrations, 3) the effect of the carbohydrate diet on excess post exercise oxygen consumption (EPOC).
Twelve male subjects (age ; 27±7 yrs) ; 6 smoker and 6 non-smoker subjects, participated in the first and second study. For 24 hour, the subjects studied during a daily life in the rabolatory. Other 6 male subjects (25±4 yrs) exercised on a cycle ergometer at 68% of their maximal oxygen uptake for 60-min in third study (exercise trial). There was no change in concentration of plasma noradrenaline sulfate (NA-S), adrenaline sulfate (AD-S) and dopamine sulfate (DA-S) after smoking and light exercise (table tennis). Following the consumption of the meal, plasma DA-S concentration increased, but concentrations of NA-S and AD-S could not be related to eating. All three CA-S concentrations showed the highest values at late evening (at 1 a.m.). There was no significant difference in magnitude of EPOC after 60-min exercise at 68% of maximal oxygen uptake between the high carbohydrate diet trial and normal mixed diet trial.
