I. To recruit an ethnically, racially and culturally diverse sample of postmenopausal women diagnosed with estrogen receptor positive breast cancer who are currently taking aromatase inhibitor (AI), establish eligibility, and randomly allocate 20 participants to a two-arm parallel intervention trial.
II. Conduct baseline measurements of: body composition and bone mineral density, reported muscle and joint pain; inflammatory, cardiovascular and bone health markers contained in blood serum; and, cardiovascular function.
III. Conduct a three month anti-inflammatory dietary intervention in one arm, and bone strengthening exercise intervention in the other study arm.
IV. At completion of these 3-month interventions, evaluate changes since baseline of body composition, bone density, reported muscle and joint pain, and inflammatory and cardiovascular measurements within each intervention arm, and preliminarily contrast changes between intervention arms.
V. Utilize results from both intervention arms to design a larger 2x2 randomized factorial trial designed to assess effects of anti-inflammatory diet, effects of bone promoting exercise, and combined diet and exercise intervention effects on joint and muscle pain, inflammatory markers, bone mineral density, and cardiovascular measures.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive a controlled anti-inflammatory diet over 12 weeks.
ARM II: Patients undergo controlled exercise sessions with a dedicated trainer 3 times a week for up to 1 hour each over 12 weeks.
After completion of study, patients are followed up at 1 week.

Experimental: Arm I (dietary intervention)
Patients receive a controlled anti-inflammatory diet over 12 weeks.
Dietary Supplement: Dietary Intervention
Receive dietary intervention
Other: Questionnaire Administration
Experimental: Arm II (exercise intervention)
Patients undergo controlled exercise sessions with a dedicated trainer 3 times a week for up to 1 hour each over 12 weeks.
Behavioral: Exercise Intervention
Receive exercise intervention
Other: Questionnaire Administration
- Bone mineral density [ Time Frame: Baseline up to 1 week post intervention ]Will be scanned by dual x-ray absorptiometry (iDXA).
- Joint and muscle pain [ Time Frame: Baseline up to 1 week post intervention ]Joint and muscle pain will be measured by the Brief Pain Inventory, a frequently administered assessment for studies of women on aromatase inhibitors (AIs). Participants will be asked about use of pain medication and supplements such as chondroitin and glucosamine. Subjects will also fill out standard visual analog scales to rate intensity of pain ranging from 1 to 10, as well as locate source of pain on standardized human figures available from International Society of Anesthetic Pharmacology. Additionally grip strength, a common marker of functional muscle and joint weakness, will be assessed using a dynamometer.
- Inflammatory markers [ Time Frame: Baseline up to 1 week post intervention ]Fasting blood samples will be collected at baseline and end of intervention. Serum markers, IL-6, Il-8, TNF-?, MCP-1, hs-CRP, leptin, TGFbeta, IL-1beta, and CRP will be quantified.
