In order to determine such an effect a study of the changes in the acid base balance and in the sugar content of the blood after exercise was carried out on sixteen children between the ages of 8 and 13 years. The effects of exercise on these changes were observed in the fasting state and after the ingestion of various sugars, principally dextrose and levulose.
The changes in the sugar content of the blood brought about by exercise, with or without the ingestion of sugar, the effects of the respiratory quotient and the concurrent changes in the acid-base balance have been studied in human adults and
