Metabolic, Physical Fitness and Mental Health Effects of High Intensity Interval Training (HIIT) in Adolescents With Type 1 Diabetes
In Brief
A clinical study evaluating HIGH INTENSITY INTERVAL TRAINING for Diabetes Mellitus, Type 1. Completed, enrolled 30 participants across 1 site.
Detailed Summary
Patients with type 1 diabetes usually present cardiovascular risk factors. Sixty percent of them are overweight or obese, 40% have hypertension, 60% have dyslipidemia, leading to cardiovascular disease as the major cause of death in adults with type 1 diabetes. Regular exercise can help patients to improve cardiovascular disease risk profile, metabolic control and chronic complications. Recommendations for exercise in children with diabetes are the same as the general population, between ages 8 to 18 years 60 min of physical exercise/day is suggested, including moderate or vigorous aerobic activity (at least 20 minutes), muscle strengthening and bone strengthening activities. Children with type 1 diabetes have poorer physical fitness levels than the non-diabetic peers and it has been described some barriers to meet these recommendations between children and adolescents with type 1 diabetes such as the fear of hypoglycemia, external temperature, work schedule, loss of control of diabetes, a low fitness level. The two types of exercise (aerobic and anaerobic) are recommended in people with diabetes. High intensity interval training involves alternation between brief periods of vigorous exercise and recovery at low to moderate intensity. Has been shown that HIIT is associated with improving aerobic capacity without a detrimental decline in blood glucose in adults with type 1 diabetes and home-based high-intensity interval training reduces barriers to exercise in the same group. The objective of the present study is to propose a HIIT exercise protocol through online modality to a group of adolescents with type 1 diabetes to evaluate the metabolic effects and physical capacity through an analytical, prospective and longitudinal study (before and after) for 3 months. As primary outcome is expected to improve metabolic control shown as an increase in time in range on continuous glucose monitoring and a decrease in glycosylated hemoglobin. And as secondary results, improve the aerobic capacity and resistance strength, lipid profile parameters, anthropometric and on the mood of the participants.
Study Details
Timeline
Interventions
Will be prescribed HIIT through online modality to a group of adolescents with type 1 diabetes 3 times a week for 3 months. The training is going to have 2 phases, the initial phase and improvement phase, which are going to be differentiated according to work intensity following the recommendations of the American College of Sports Medicine. During the initial phase (first 4 weeks) the intensity is going to be 60-75% of the VO2 max. During the improvement phase the intensity is going to increase to a 75-85% of the VO2 max for 8 week.
