詳細な説明
Compare values and trends of different biomarkers (glucose, lactate and beta-hydroxybutyrate) before, during and after morning aerobic and symptom limited maximal exercise (cycling) to predict glycemic fluctuations (hypo- and hyperglycemic events) during and after exercise in order to create treatment algorithms to prevent these events.
Endpoint:
• Evaluate values and trends of glucose, lactate and beta-hydroxybutyrate before, during and after morning exercise in venous blood.

説明
Inclusion Criteria:
- Male adults (18-40 years old) with T1D, diagnosed since > 1 year
- Using a CGM (Dexcom G5) or willing to wear a CGM (Dexcom G5) for the duration of the study.
The CGM must be applied >48h before the exercise test
- Participants are on intensified insulin therapy (MDI) or insulin pump therapy (CSII)

Exclusion Criteria:
- Recently diagnosed T1D (< 12mo)
- Participants not on MDI or CSII
- Musculoskeletal disorder that affects cycling or is a contra-indication for vigorous physical activity
- Cardiorespiratory disease or ECG abnormality that is a contra-indication for vigorous physical activity
- Having an acute illness (e.g. influenza) that interferes with glucose metabolism
- Having a metabolic disorder (different from diabetes) or takes drugs known to have significant interference with glucose metabolism, such as systemic corticoids as judged by the investigator
- Current treatment with drugs known to have significant interference with glucose metabolism, such as systemic corticoids as judged by the investigator
- Presence of concomitant pathology such as heart failure, liver failure, kidney failure defined as eGFR <45mL/min
