NCT05619198

Brief Summary

Objective: The overall objective of this study is to assess the efficacy of the current recommended guidelines for physical activity (PA) in response to acute moderate intensity continous exercise (MICE) and high intensity interval exercise (HIIE) among adolescents with type 1 diabetes (T1D) using automated insulin delivery (AID) systems (MiniMed 780G and Tandem Control-IQ). Methods: This study will be a two-period, cross-over, clinical trial with between and within cohort comparisons of two different exercise modalities among a total of 24 age-, sex-, and insulin-dose-matched adolescents with T1D (12 using MiniMed 780G and 12 using Tandem Control-IQ). Endpoint: The primary endpoint is sensor-derived time in range (3.9 mmol/L-10.0 mmol/L) around exercise

Outcome Measures

Primary Outcomes (1)

  • Percentage of time spent in sensor-derived time in range (3.9-10.0 mmol/L) during and after a bout of exercise

    Percentage

    T = 0 to T = +120 (120 minutes)

Secondary Outcomes (32)

  • Number of hypo- (<3.9 mmol/L) and hyperglycemic (>10.0 mmol/L) occurrences during exercise session as measured by sensor and plasma sampling

    T = 0 to T = +45 (45 minutes)

  • Percentage of time spent below (<3.9 mmol/L), in (3.9-10.0 mmol/L) and above (>10.0 mmol/L) range during in-clinic phase, measured by sensor and plasma sampling

    T= -60 minutes to T= +120 minutes (3 hours)

  • Percentage of time spent below (<3.9 mmol/L), in (3.9-10.0 mmol/L) and above (>10.0 mmol/L) range during home-phase, measured by glucose sensor

    24 hours

  • Glycemic variability as coefficient of variation, measured by sensor during in-clinic phase

    T= -60 minutes to T= +120 minutes (3 hours)

  • Glycemic variability as coefficient of variation, measured by plasma sampling during in-clinic phase

    T= -60 minutes to T= +120 minutes (3 hours)

  • +27 more secondary outcomes

Study Arms (2)

High Intensity Interval Exercise

ACTIVE COMPARATOR

Plasma and sensor glucose is monitored before, during and after a bout of high intensity interval exercise

Behavioral: High Intensity Interval Exercise

Moderate Intensity Continous Exercise

ACTIVE COMPARATOR

Plasma and sensor glucose is monitored before, during and after a bout of moderate intensity continous exercise

Behavioral: Moderate Intensity Continous Exercise

Interventions

High Intensity Interval Exercise: * 5 minutes resting phase @ 0 watts. * 5-minute warm up phase @ 20 watts. * 40 minutes of interval work consisting of eight bouts of 1-minute cycling at a power output corresponding to \~85% of VO2max interspersed with 4-minute recovery periods at 20 watts. * 5 minutes resting phase @ 0 watts.

High Intensity Interval Exercise

Moderate Intensity Continous Exercise: * 5 minutes resting phase @ 0 watts. * 5-minute warm up phase @ 20 watts. * 40 minutes of MICE 65% VO2max. * 5 minutes resting phase @ 0 watts.

Moderate Intensity Continous Exercise
