This is a mixed-methods randomized controlled trial assessing the effects of an online and in person 12-week movement intervention compared to an education only control group on heart rate variability, self-compassion, psychological well-being, fatigue, exercise self-efficacy, physical activity identity, and body image in postpartum women.
This is a mixed-methods randomized controlled trial assessing the effects of an online and in person 12-week movement intervention compared to an education only control group on heart rate variability, self-compassion, psychological well-being, fatigue, exercise self-efficacy, physical activity identity, and body image in postpartum women. Participants will be randomized into one of three groups: 1) in person yoga movement intervention, 2) online yoga movement intervention, 3) education group. Heart rate variability will be measured using a chest strap at the beginning and end of the 12 week intervention. At the beginning and end of the 12 week intervention, and at 3-months post-intervention, questionnaires will be completed online to assess self-compassion, psychological well-being, fatigue, exercise self-efficacy, physical activity identity, and body image.
