[Physical fitness during pregnancy].

In a study of longitudinal section 25 primigravidae were examined during pregnancy on the bicycle ergometer. A group of 10 non-pregnant women in their postmenstrual phase was used as controls. Blood glucose, cholesterol, triglyceride and lactic acid were analysed parameters in addition to cardiorespiratory. The reaction of the cardiovascular system to submaximal load in healthy pregnant women is economic. The metabolic system reacts with an intensified availability of energy via fat-metabolism and a diminished utilisation of glucose. Pregnancy is a physical stimulus for the female organism.
