Effects of Six Months of Yoga on Breast Cancer Survivors

What’s This Research About?

It’s been shown that yoga improves quality of life (QOL) and flexibility for cancer survivors, but how does it affect specific fitness markers in breast cancer survivors? This study assessed specific fitness outcomes such as VOmax, strength, flexibility, BMI, and body fat. They also compared results from the yoga practice with two other different exercise programs.

Comparison group (C): This group was allowed to choose their own exercise routine, but were encouraged to take classes offered by DIVA (Deriving Inspiration and Vitality through Activity). The DIVA program is a “self-referral program that offers support services for breast cancer survivors.” They offer various types of group exercise classes (strength training, Tai Chi, Zumba, etc.).

Comprehensive individualized exercise program (CE): A one-hour exercise routine that consisted of aerobic, resistance, and flexibility training.

Rate of Perceived Exertion (RPE): In sports and particularly exercise testing, the Borg RPE Scale measures perceived exertion. In medicine this is used to document the patient’s exertion during a test, and sports coaches use the scale to assess the intensity of training and competition. The RPE scale is used to measure the perceived intensity of your exercise and runs from 0 – 10. 

Sub maximal VO2 test: A sub-maximal graded exercise progression (according to ACSM guidelines) done on a cycle ergometer while recording O2 and heart rate values. VO2 max is then estimated using regression analysis with these values.

VO2: A measurement of Oxygen intake and use (ml O2/kg/min).

VO2max: A measurement of the highest amount of oxygen taken in and used during a maximal exertion test (usually on treadmills or cycle ergometers).

Yoga based exercise (YE): A one-hour Hatha yoga class which consisted of modified sun salutations, standing, seated, quadruped, supine, prone, and rotation postures, and 10 minutes of savasana at the end.

About the Author:

Catherine brings to her role as a personal trainer a wealth of education and years of athletic experience with training in track and cross country running, gymnastics and rowing, boxing and yoga. She received a B.A. in Sports Medicine and Exercise Physiology from the University of San Francisco and an M.A. in Kinesiology at San Francisco State University. She also holds certifications in ACE, FMS I and II, PRI (Myokinematics, Respiration), Neuromuscular therapy, FRCms, and FR. As an athlete she sustained several injuries, which led her on the path to study and understand the body and the mechanisms of healing. "I was fascinated with everything I learned. Throughout college, I worked with USF athletes as an athletic trainer in the prevention and rehabilitation of injuries. Soon I was able to transfer all of this knowledge into helping everyday people with their aches and pains." Her thirst for knowledge is never quenched and she continues to evolve her practice to stay up to date on the latest research and methods to help her clients with present injuries, pain, and best ways to acquire strength to maintain a healthy body. "I believe assessment is still key in starting with clients but stability, global strength and everyday movement are key to people's longevity, and quality of life. If people can slowly and systematically expose their bodies to different loads to gain strength and mobility they will better succeed to get the most out of their bodies."
