Exercise-physiological approach in the analysis of blood glucose curves.
The effect of a single bout of oral glucose administration on the blood glucose level during three hours of observation was studied at rest in 6 physical education students and in 6 elite walkers with different physical condition. The influence of the physical condition on the observed data was also investigated. The evaluation of the glucose tolerance test (OGTT) was first built on a mathematical model and it was developed by a new method. The point of the brand-new method is the interrelationship between the relative percentage differences of blood glucose values, which is analysed as a function of time. The data of the new method better reflect the alterations of blood glucose regulation after oral administration of glucose. The new method contributes to the more accurate analysis of OGTT curves for beside estimation of the absolute values, it considers the relative differences, thus a thorough examination of the glucose metabolism can be carried out. It opens new potentialities in the analysis of the individual, absorptive, hormonal and fitness-dependent effects of different carbohydrates that are used abundantly by athletes.
