High volume‐low intensity exercise camp and glycemic control in diabetic children

Abstract

To evaluate the effects of the designed regime encompassing high volume-low intensity physical activity programme on glycemic control in diabetic children, 20 subjects (age 12.81 +/- 2.14) spent 2 weeks in a controlled environment of a summer camp. An exercise physiologist and a kinesiology specialist programme and conducted the three exercise sessions a day. Total daily caloric intake was controlled and the blood glucose was monitored four times a day with special concern for hypoglycaemia episodes. Short and long-term effects (HbA1c) of the summer camp were evaluated 10 days and 2 months following programme completion. The insulin dosage was not lowered at the beginning of the camp for everyone, but it was individually modified according to the blood glucose monitoring. Initial HbA1c was 8.28 +/- 1.3% and decreased to 7.92 +/- 1.42% measured 10 days after the camp (P = 0.023) while the number of children with the satisfactory HbA1c level lower than 7.5% doubled. HbA1c increased again 2 months following the camp. The average blood glucose concentrations decreased in the last days of the camp when compared with the first day in three out of four daily measurements (P < 0.05). There were only two clinically manifested hypoglycaemia episodes recorded. With a low rate of hypoglycaemia crisis and better glycemic control the proposed programme was found to be satisfactory but the downside was that the duration of the effects was too short. With no participation in organised exercise programmes and with absence of controlled nutrition, the beneficial effects of the camp disappeared within 2 months after the camp.
