Outcome Measures

Primary Outcomes (3)

  • Heart rate

    Resting heart rate will be measured immediately prior-to exercise. Change in heart rate will be measured during and following exercise.

    40 minutes

  • Fatigue

    Fatigue will be assessed immediately before, immediately following, 30- and 60-minutes following exercise using the Visual Analog Scale to Assess Fatigue Severity.

    10 minutes

  • Physical activity and sedentary behaviour

    Participants will wear an accelerometer and activPAL (Actigraph wGT3X-BT Monitor, Actigraph LLC; activPAL, PAL Technologies Ltd.) for seven consecutive days and nights to record 24-hour physical activity and sleep/wake measurements.

    7 days

Secondary Outcomes (1)

  • Glucose

    40 minutes

Study Arms (4)

Pregnant with Multiple Sclerosis

Pregnant individuals (\> 13 weeks) with a Multiple Sclerosis diagnosis.

Other: Moderate-intensity cardiovascular exercise

Pregnant without Multiple Sclerosis

Pregnant individuals (\> 13 weeks) without Multiple Sclerosis.

Other: Moderate-intensity cardiovascular exercise

Postpartum with Multiple Sclerosis

Postpartum individuals (\< 1 year since delivery) with a Multiple Sclerosis diagnosis.

Other: Moderate-intensity cardiovascular exercise

Postpartum without Multiple Sclerosis

Postpartum individuals (\< 1 year since delivery) without Multiple Sclerosis.

Other: Moderate-intensity cardiovascular exercise

Interventions

The participant will be instructed to first rest quietly for 10 minutes wearing a heart rate monitor. The participant will then be instructed to exercise at an intensity of 60-70% heart rate reserve (HRR) for 20 minutes. The participant may choose any kind of cardiovascular exercise modality they prefer, as long as the exercise will meet the prescribed intensity. Following exercise, participants will rest quietly for 10 minutes wearing the heart rate monitor.
