Isolated and Combined Effect of a Low Carbohydrate Diet and Chronic Exercise Exposure to Hypoxia on Glycaemic Control and Cardiovascular Risk Factors in Patients With Type 2 Diabetes
In Brief
A clinical study evaluating Exercise in normoxia, Control diet, and 2 other interventions for Carbohydrate and 3 related conditions. Completed, enrolled 42 participants across 2 sites.
Detailed Summary
The purpose of this study is to determine the effects of isolated chronic exercise in hypoxia and combined exercise in hypoxia with a low carbohydrate diet on hypoxia-induced transcription factor (HIF1-α); glycaemic control and cardiovascular risk factors in patients with type 2 diabetes.
Study Details
Timeline
Interventions
Exercise at sea level, 3 sessions per week, during a 8-week period intervention and will consist in 60 min on an ergometer, of continuous moderate and high intensity interval training. . All exercise testing and training sessions will be carried out at the same time of day (± 2 hours) and visits will be separated by at least 48h of recovery.
Control diet: diet plans will be individualized and energy-content prescriptions will be constant throughout the study to maintain the isocaloric control between diets. The planned macronutrient compositions will be 20% of energy from fat, 20% from protein and 60% from carbohydrates for the low-fat diet during the 8 weeks. Diets emphasis on low-glycemic index foods and limited saturated fat to 10% of energy. Participants will meet individually with a dietitian two times for 8 weeks and should start the dietary intervention along with the intervention with exercise.
Exercise at 3000m altitude, 3 sessions per week, during a 8-week period intervention and will consist in 60 min on an ergometer, of continuous moderate and high intensity interval training. . All exercise testing and training sessions will be carried out at the same time of day (± 2 hours) and visits will be separated by at least 48h of recovery.
