Brief summary

Interventional research with minimal risks and constraints on the effects of circadian rhythm on glycemic regulation during intense moderate, continuous and intermittent exercise in adolescents living with type 1 diabetes

Detailed description

Single-center, randomized, controlled study in adolescents living with type 1 diabetes. This study aims to evaluate the effect of exercise timing (morning vs. afternoon) and exercise type (continuous vs. intermittent) on blood glucose levels during and after exercise, as well as to assess the effect of exercise timing (morning vs. afternoon) and type of exercise (continuous vs. intermittent) on blood glucose during and after exercise

Interventions

continuous and intermittent exercise on cycloergometer

Masking description

It is not possible to do a trial in blind or double blind because the moment of the day and the exercice modality can not be hidden, however the results analysis will be assessed in blind

Intervention model description

4 randomized handovers performed (on different days with meal/snack)previous standardized: * Continuous exercise on ergocycle in the morning * Continuous exercise on ergocycle in the afternoon * Intermittent exercise on ergocycle in the morning * Intermittent exercice on ergocycle in the afternoon

Inclusion criteria

* Children and adolescents aged 10 to 16; * Living with type 1 diabetes for at least 1 year with HbA1c less than or equal to 12%; * Socially insured ; * Having given their written consent to participate in the research, as well as that of their legal guardians; * Willing to comply with all research procedures and duration.

Exclusion criteria

* Clinically significant microvascular complications: nephropathy (estimated glomerular filtration rate less than 40 ml/min), neuropathy or severe proliferative retinopathy as assessed by the investigator; * Recent acute macrovascular event (\< 3 months), e.g. acute coronary syndrome or cardiac surgery; * Abnormal blood picture and/or anemia; * Current pregnancy; * Other serious medical condition likely to interfere with study participation or ability to complete exercise periods in the judgment of the investigator (e.g., orthopedic limitation); * Inability to receive informed information; * Inability to participate in the entire study; * Lack of social security coverage; * Refusal to sign the consent form.
