Outcome Measures

Primary Outcomes (1)

  • Glycemic Response During Exercise and Early Recovery

    Comparison of glycemic response (from blood glucose) during exercise and early recovery between each exercise strategy.

    0 to 75 minutes following exercise initiation (0, 5, 10, 15, 25, 35, 45, 50, 55, 60, 75 min)

Secondary Outcomes (11)

  • Number of Participants With Hypoglycemia (<70 mg/dL) During Exercise and Early Recovery

    0 to 75 minutes following exercise initiation

  • Number of Participants With Hyperglycemia (≥250 mg/dL) During Exercise and Early Recovery

    0 to 75 minutes following exercise initiation

  • Continuous Glucose Monitor (CGM) Metrics During Late Recovery - Nadir Glucose

    90 min after the standard meal until 1200 noon the day after each exercise session

  • CGM Metrics During Late Recovery - Peak Glucose

    90 min after the standard meal until 1200 noon the day after each exercise session

  • CGM Metrics During Late Recovery - Mean Glucose

    90 min after the standard meal until 1200 noon the day after each exercise session

  • +6 more secondary outcomes

Study Arms (4)

Control

NO INTERVENTION

No basal insulin adjustment, no carbohydrate intake (until glucose drops \<70 mg/dL).

Basal insulin reduction

ACTIVE COMPARATOR

Basal insulin reduction to 50% five minutes before the start of exercise.

Other: Basal Insulin Reduction

Eligibility Criteria

Age18 Years - 64 Years

You may qualify if:

  • Clinical diagnosis of presumed autoimmune type 1 diabetes, receiving daily insulin

  • Using continuous subcutaneous insulin infusion (CSII; insulin pump) for at least 6 months, with no plans to discontinue pump use during the study
  • Exercises regularly, i.e. ≥30 minutes moderate or more vigorous aerobic activity X ≥3 times/week
  • Body mass index (BMI) \<30 kg/m2
  • Females must meet one of the following criteria:
  • Of childbearing potential and not currently pregnant or lactating, and agrees to use an accepted contraceptive regimen as described in the study procedure manual throughout the entire duration of the study; or
  • Of non-childbearing potential, defined as a female who has had a hysterectomy or tubal ligation, is clinically considered infertile or is in a menopausal state (at least 1 year without menses)
  • In good general health with no conditions that could influence the outcome of the trial, and in the judgment of the investigator is a good candidate for the study based on review of available medical history, physical examination and clinical laboratory evaluations
  • Willing to adhere to the protocol requirements for the duration of the study
  • Must be enrolled in the T1D Exchange clinic registry or willing to join the registry

You may not qualify if:

  • One or more severe hypoglycemic episodes in the past 12 months (as defined by an episode that required third party assistance for treatment)
  • Active diabetic retinopathy (proliferative diabetic retinopathy or vitreous hemorrhage in past 6 months) that could potentially be worsened by exercise protocol
  • Peripheral neuropathy with insensate feet
  • Cardiovascular autonomic neuropathy with inappropriate heart rate response to exercise
  • Use of non-insulin anti-diabetic medications
  • Use of beta-blockers
  • Use of agents that affect hepatic glucose production such as beta adrenergic agonists, xanthine derivatives
  • Use of Pramlintide
  • Currently following a very low calorie or other weight-loss diet
  • Participation in other studies involving administration of an investigational drug or device within 30 days or 5 half-lives, whichever is longer, before screening for the current study or planning to participate in another such study during participation in the current study
