Yoga Practice for Breast or Ovarian Cancer Patients

Not Applicable

Completed

Interventions: Other: Vigorous yoga practice
Other: Restorative (gentle) yoga practice

Brief Summary: Previous research suggests that regular physical activity may make cancer survivors do better in the long run. Laboratory studies suggest that stress may be bad for cancer patients as well. The investigators are interested in whether yoga, a practice that combines physical activity and stress reduction, is beneficial to cancer survivors. To answer that question, the investigators will need to do a large scale clinical trial.

Before the investigators can do that large study, they need to know whether people are willing to participate in this kind of study, whether they can do the yoga practice regularly and for how long, what kind of changes they may experience in how they can handle their daily activities, emotion, sleep, memory and problem solving ability, and what are the changes that can happen in their body after doing the yoga practice. Answering these questions is what this study is about.

Arm && Interventions

Group	Intervention	Description
Vigorous yoga practice	Vigorous yoga practice	Supervised vigorous yoga practice, 60 minutes/session, 3 sessions/wk for 12 weeks, followed by 12 weeks of home practice.
Restorative (gentle) yoga practice	Restorative (gentle) yoga practice	Supervised restorative (gentle) yoga practice, 60 minutes/session, 3 sessions/wk for 12 weeks, followed by 12 weeks of home practice.

Primary Outcome Measures

Name	Time	Method
feasibility of a supervised vigorous yoga practice by the number of patients that complete study.	2 years	The study will be deemed feasible and safe if at least 15/20 patients in each arm complete the study. If the underlying feasibility rate is 90%, then the probability of 15/20 patients or more completing the study is 98.9%, and 97.8% for 15/20 patients completing in the study in both arms simultaneously.
safety of a supervised vigorous yoga practice by the number of serious adverse events reported.	2 years	Each serious adverse event (SAE), defined as grade III or IV toxicity, will be evaluated by the PI or a Co-PI and its relationship to the study intervention is determined by the PI or a Co-PI. The study will be deemed feasible and safe if at least 15/20 patients in each arm complete the study.
