Filter by:Certain types and timings of exercise are known to cause hyperglycemia (high blood glucose) in people with type 1 diabetes. Hyperglycemia increases the risk of most long-term complications for individuals with this complication. However, using insulin corrections to treat post-exercise hyperglycemia can increase the risk of late-onset hypoglycemia (low-blood glucose). Anaerobic activities performed in a fasted state are known to cause increases in blood glucose and post-exercise hyperglycemia in most individuals with type 1 diabetes. This study proposes to examine the effect of a ten-minute aerobic cool down after resistance exercise on the blood glucose response to fasted exercise of individuals with type 1 diabetes. It is hypothesized that adding a short aerobic cool down at the end of a fasted resistance exercise session will attenuate post-exercise increases in blood glucose observed in previous studies, leading to less post-exercise hyperglycemia.
Regular physical activity has substantial health benefits in people with type 1 diabetes. The fear of hypoglycemia, both during and after exercise, is a major barrier to exercise in this population. A major obstacle to providing specific physical activity and exercise advice is that there are still significant gaps in the fundamental understanding of the impact of physical activity and exercise on blood glucose levels in type 1 diabetes. Women with type 1 diabetes have a substantial increase in cardiovascular risk once they have passed menopause. They may lose both bone quality and muscle mass at a faster rate with aging than those without diabetes. Overall, these changes greatly increase the risk of both cardiovascular and frailty related complications. Despite the many potential benefits of resistance exercise for post-menopausal women with type 1 diabetes, there are currently no published studies examining the effects of resistance exercise in this population. Before being able to design a clinical trial of resistance exercise, an examination of the acute effects of resistance exercise on blood glucose levels in post-menopausal women with type 1 diabetes is required. The present study will compare the glycemic effects of a low resistance, high repetition (3 sets of 15 to 20 repetitions) weight lifting program to the effects of a moderate resistance, moderate repetition (3 sets of 8 to 10 repetitions). The investigators hypothesize that the high repetition program will be associated with a bigger decline in blood glucose during exercise, but that the moderate resistance program will be associated with a higher risk of post-exercise hypoglycemia.
Prospective, randomized, open-label, two-sequence crossover study to investigate the effects of continuous subcutaneous insulin injection (CSII, using DIA:CONN G8 insulin pump) in pediatric patients with type 1 diabetes using multiple daily insulin (MDI) injection
The investigators aim to assess the glycemic outcomes of a fully automated insulin-and-pramlintide artificial pancreas and a comparator insulin-alone artificial pancreas with carbohydrate matched boluses.
Food forms an integral part of diabetes management. As children mature into young adults, they must learn to adopt lifestyle behaviours critical for optimal diabetes care. The development of food preparation and cooking skills at a young age may help to facilitate healthy food choices in children and provide a solid foundation for young adulthood. Food skills workshops are effective interventions that have been shown to improve food literacy and healthy eating in the general pediatric population. However, food skills programs have not been adequately evaluated in children with type 1 diabetes. Further, virtual programs are not well assessed, which can increase the accessibility of food education during the pandemic and in the future.
Participants will be asked to wear a continuous glucose monitor for at least three days on three separate occasions. One testing session will be a no-exercise resting control session (90 minutes). One will be a moderate aerobic exercise session (30 minutes of exercise, 60 minutes of recovery), and the third will be a moderate weight-lifting session (~30 minutes of exercise, 60 minutes of recovery).The investigators will measure changes in blood glucose during exercise by drawing blood during and after exercise. Post-exercise glucose trends will be examined using continuous glucose monitoring.
Female participants with type 1 diabetes using oral contraceptives will be asked to wear a continuous glucose monitor for at least three days on two separate occasions (once during the last week of active pills and once during the no pill/placebo pill phase of the menstrual cycle). An exercise session (45 minutes of aerobic exercise at 60% VO2peak on a cycle ergometer) will take place at 5 pm on the second day of glucose monitoring.
The purpose of this research study is to understand how type 1 diabetes (T1D) increases the risk for cardiovascular diseases (heart attack and stroke). To this end, the investigators will compare apolipoprotein and triglyceride kinetics in people wtih T1D and healthy control participants.
This is a study assessing the feasibility of using the insulin-only configuration of the iLet bionic pancreas with initiation in pump-naïve people with type 1 diabetes in a primary care practice with either in-person training and follow-up (PC-IP) or with training and follow-up via telehealth (PC-TH). As a comparison, the iLet will be initiated by an academic endocrinology practice with either in-person training and follow-up (EN-IP) or with training and follow-up via telehealth (EN-TH).
This study proposes to examine the impact of time of day (morning versus afternoon) on the variability of blood glucose responses to high resistance exercise in a single group of patients with type 1 diabetes. Participants will be asked to wear a continuous glucose monitor during the 3 weeks of testing. During the six exercise sessions (three in the morning while fasted and three in the afternoon), participants will complete the same resistance exercise protocol.
