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.
