[Hemorrheological changes induced by submaximal exertion in subjects with insulin-dependent diabetes mellitus].

The influence of an acute physical exercise on hemorheological parameters in insulin-dependent diabetes mellitus in not actually known. We have examined the behavior of hemorheological parameters and other laboratory findings such as blood glucose, blood lactic acid, O2 and CO2 venous pressure and venous pH before and after a submaximal physical exercise standardized by ECG monitoring and by means of an 'oxygen consumption computer'. The work load was significantly lower in diabetic patients than in normal control subjects. On the other hand, changes in hemorheological parameters were more evident in diabetic patients. The significance of these findings is also discussed.
