    Abstract:
    It is a recognized fact that diabetics stand greater risk of developing diseases of the heart and circulation system. Active sport participation, however, can reduce this risk and is therefore of particular importance for diabetics. In order to give the juvenile type diabetics the best possible advice on a 15 minute physical training program, we examined 6 insulin-dependent diabetics and compared their insulin and glucose regulation during physical activity and recovery with that of 6 healthy hobby-sportsmen of the same age. During the phase of recovery a highly significant difference in the blood sugar levels was observed (p less than 0.01). Whereas the blood sugar levels of the healthy group increased quickly in the first 5 minutes immediately following the course of activity, it was seen to decrease during the phase of recovery in 4 diabetics and 2 diabetics showed mostly a very slight increase. The insulin levels of the healthy group remained constant both during activity and recovery. Widely differing, but nevertheless constant values were also shown in the diabetics insulin levels during the course of activity. In the recovery phase however divergent courses were observed. The insulin levels of 4 diabetics increased and of the other 2 they decreased slightly. Juvenile type diabetics therefore show no special characteristics compared to their healthy counterparts during a 15 minute physical activity. In the recovery phase however their blood glucose increase reaction is lacking. This reaction is in fact impeded by the slight increase of the insulin level. Thus, juvenile type diabetics are potentially prone to hypoglycemia immediately following physical activity.(ABSTRACT TRUNCATED AT 250 WORDS)
