Prior to the widespread use of continuous glucose monitoring (CGM), knowledge of the effects of exercise in type 1 diabetes (T1D) was limited to the exercise period, with few studies having the budget or capacity to monitor participants overnight. Recently, CGM has become a staple of many...

OBJECTIVE-To determine the effects of exercise order on acute glycemic responses in individuals with type 1 diabetes performing both aerobic and resistance exercise in the same session. RESEARCH DESIGN AND METHODS—Twelve physically active individuals with type 1 diabetes (HbA1c 7.1 ± 1.0%)...

Islet transplantation (ITx) is effective in preventing severe hypoglycemia by restoring glucose-dependent insulin secretion in type 1 diabetes (T1D), but may not normalize glucose regulation. Studies suggest that physical activity plays a role in maintaining β-cell mass and function in...

We compared growth hormone (GH) and plasma glucose (PG) levels in type 1 diabetic individuals performing aerobic before resistance exercise (AR) to when resistance exercise was performed first (RA). In AR, GH secretion declined in late exercise while it rose throughout exercise in RA, resulting...

It is relatively well known that moderate-intensity aerobic exercise increases the risk of hypoglycemia in individuals with type 1 diabetes. Conversely, brief high-intensity (anaerobic) activity can cause post-exercise hyperglycemia. Recent evidence has indicated that including small amounts of...

OBJECTIVE-In type 1 diabetes, small studies have found that resistance exercise (weight lifting) reduces HbA(1c). In the current study, we examined the acute impacts of resistance exercise on glycemia during exercise and in the subsequent 24 h compared with aerobic exercise and no...

Objective: Recommendations for insulin adjustments and carbohydrate intake exist for individuals with type 1 diabetes undertaking moderate exercise. Very few guidelines exist for athletes with type 1 diabetes competing in higher intensity and/or longer duration events. This observational study...
