Abstract Ten young non-athletes were investigated during a run on the sport field of 1 and 2 h duration. Telemetrically recorded mean heart rate was 176 min−1 in the former and 163 min−1 in the latter exercise. Blood glucose level fell in both cases by about 0.5μ moles/ml. Blood lactate attained a peak at the 15th min (6,95 for the 1 h and 3,74 μmoles/ml for the 2 h run), thereafter showing a continual decrease. Whereas the increase in plasma total lipids and triglycerides was only moderate, free glycerol increased up to 5- and 8-fold, respectively, and the level of free fatty acids rose to 1.85 and 2.27 μmoles/ml. The increase of FFA and glucose after both types of work is the result of the lipid mobilization and reflects the decrease in carbohydrate utilization and the increase in fat oxidation.
