Study summary

Adults with irritable bowel syndrome (IBS) are being randomized to a yogic breathing or control condition. Participants randomized to the yogic breathing group will be asked to complete a 2-minute yogic breathing video 5 to 7 days per week at home for 4 weeks and control group participants will be asked to maintain their current activities. Participants in this group will be given access to the yogic breathing video at the end of the 4-week control period. IBS symptoms and autonomic and vascular function will be assessed at baseline and at the end of week 4 in both groups.

Study arms

  • Experimental
    Yogic breathing intervention

    Participants assigned to this group will complete a 20-minute yogic breathing video at least 5 days per week for 4 weeks. All sessions except the initial yogic breathing session will be completed at home. Participants will complete the first session at Texas State under the supervision of the investigative team for familiarization.

    Behavioral: Yogic breathing intervention

  • No intervention
    Control

    Participants in the control group will be asked to maintain their current daily activities and will be given access to the yogic breathing video once all follow-up testing has been completed at the end of week 4.

Interventions

  • BehavioralYogic breathing intervention

    Yogic breathing will be completed while following a video provided by the investigative team. Breathing practices consist of slow, deep, relaxation breathing and are led by a certified yoga instructor.
