Glucose or intermittent high-intensity exercise in glargine/glulisine users with T1DM.
INTRODUCTION The effects of glargine/glulisine insulin regimen on exercise blood glucose ( BG ) and strategies to limit exercise-induced hypoglycemia are not well documented . Intermittent high-intensity exercise has been proposed to prevent hypoglycemia , but its effect in participants with type 1 diabetes using glargine/glulisine  is unknown . METHODS The study used a repeated- measures design with three r and omly ordered exercise conditions . Eleven participants completed 60 min of moderate-intensity exercise  at 50 % VO(2peak ) for all conditions . These conditions varied as follows : participants ingested 0 g of glucose preexercise ( 0 G + MOD ) , 30 g of glucose preexercise ( 30 G + MOD ) , or 0 g of glucose preexercise but performed brief high-intensity intervals interspersed every 2 min ( 0 G + MOD/INT ) during exercise . If BG fell < 4 mmol·L(-1 ) , a 20 % dextrose solution was started to maintain BG between 4 and 5 mmol·L(-1 ) . RESULTS Consuming 30 g of glucose before exercise ( 30 G + MOD ) result ed in a higher preexercise BG ( 11.7 ± 2.7 mmol·L(-1 ) ) compared with 0 g of glucose before exercise ( 0 G + MOD , 7.8 ± 4.0 , and 0 G + MOD/INT , 9.2 ± 3.5mmol·L(-1 ) ) , P < 0.05 . A dextrose infusion was required in 7/11 , 4/11 , and 1/11 participants for 0 G + MOD , 0 G + MOD/INT , 30 G + MOD conditions , respectively , P < 0.02 . The duration and the quantity of dextrose infused were greatest in the 0 G + MOD condition , moderate in the to 0 G + MOD/INT condition , and minimal in the 30 G + MOD condition , P < 0.01 . CONCLUSION Our results suggest that both moderate-intensity exercise with a 30-g preexercise glucose beverage or interspersed with intermittent high-intensity sprints may be safe strategies to prevent hypoglycemia in glargine/glulisine users
