[Acute physical workload and glucose serum concentration in subjects with different level of physical activity].
The aim of this study was to estimate glucose serum concentration during acute workload in the subjects with different level of physical activity. The study involved a group of healthy males, average 21 years of age, which, based on the level of their physical activity, were divided into two groups: trained and untrained subjects. Acute work load of 30 minutes duration was carried out on byciclergometer following the protocol of individually adjusted constant work load. The glucose serum concentration was measured in the rest and during exercise (6., 12. 18., 24. and 30. minutes). The standard glucose oxidase method was used to determine serum glucose concentration. The serum glucose concentration was in the mean refferal values in the rest period, and during exercise in both examined groups. In the trained group of subjects there was no statistically significant changes in glucose serum concentration during acute work load. In the untrained group of subjects we established decrease in glucose serum concentration during exercise (at 18th., 24th. and 30th) compared to the concentration at rest period. Level of physical activity does not cause significant changes in the glucose serum concentration during acute work load of moderate intensity. Trained subjects have better ability of serum glucose concentration maintenance during exercise compared with sedentary subjects.
