Background: Physical activity (PA) poses an additional burden on people living with type 1 diabetes (T1D) as it increases the risk of hypoglycemia, if performed at a moderate intensity. It is hypothesized that adding vigorous PA (VPA) into moderate PA (MPA) may help attenuate exercise-related hypoglycemia.
Methods: Seventeen participants with T1D (23.7±6.6 years) completed an observational study of six days with continuous glucose monitoring and accelerometer-derived measures of PA to determine the association between PA intensity and both hypoglycemia risk and glucose variability (GV).
Results: Higher evening moderate-to-vigorous PA (MVPA) increased the risk of overnight hypoglycemia (OR 1.03; 95% CI 1.002-1.047, p=0.031). Increased evening VPA was not associated with reduced hypoglycemia, but decreased overnight GV (3.20±0.25 for low vs 2.27±0.29 for high; p=0.022).
Conclusions: Performing evening MVPA increases hypoglycemia risk overnight, but incorporating VPA did not prove to be protective. However, VPA reduced GV, which is a predictor of hypoglycemia. / May 2016
