Short sprint prevents low blood sugar postexercise
Mar 09 (Reuters Health) - A 10-second maximal sprint after moderate-intensity exercise reduces the risk of postexercise hypoglycemia (low blood sugar) in young people with insulin-dependent (type 1) diabetes, according to a study.
This study, the researchers say, "provides the first evidence that a short maximal sprint effort performed immediately after moderate-intensity exercise is preferable to only resting as a means to counter a further fall in glycemia after exercise, thus decreasing the risk of early postexercise hypoglycemia in individuals with type 1 diabetes."
"On this basis," they write in the journal Diabetes Care, "one might tentatively recommend that after exercise of moderate intensity, young individuals with complication-free type 1 diabetes consider performing a short 10-second sprint to counter a further fall in their blood glucose level...particularly if a source of dietary carbohydrate is not readily available."
But in comments to Reuters Health, study investigator Dr. Paul A. Fournier cautioned that while the use of a 10-second sprint "constitutes a novel and simple approach to decrease the risk of post-exercise hypoglycemia that will revolutionize blood glucose management in type 1 diabetes, it would be premature and irresponsible at this stage to advocate its widespread adoption, because much more research is required to identify the target population of type 1 diabetic patients likely to be responsive."
"So far," Fournier emphasized, "only healthy young individuals have been tested in our study, and all have responded positively."
Fournier, from the University of Western Australia, Crawley, and colleagues investigated whether a 10-second maximal sprint could counter the continual decline in blood sugar during recovery from moderate-intensity exercise in seven type 1 diabetic men, who were an average of 21 years old.
After 20 minutes of moderate-intensity exercise, the subjects experienced a rapid and significant decrease in blood glucose levels, the authors report.
However, a 10-second maximal sprint immediately following the moderate-intensity exercise stopped a further decline in blood glucose levels for the next 2 hours, the results indicate.
In contrast, moderate-intensity exercise followed by a rest period led to a further decrease in blood glucose levels.
Fournier notes that more study is needed in other groups of type 1 diabetic patients such as children and sedentary middle-aged individuals. "It is our view that the effect of sprinting on reducing the risk of post-exercise hypoglycemia is probably not as marked in children and sedentary middle-age individuals with type 1 diabetes, in part, due to their reduced capacity to engage in a maximal sprint effort," he told Reuters Health.
