Intervention: Omega-3
Description: The study supplement, omega-3-fish oils, is taken as 3 gel capsules daily that together contain approximately 2 grams of fish oil. Each gel capsule (1/3 of the daily dose) has a total omega-3 dosage of 615 mg with two major omega-3 components of ethyl eicosapentaenoic acid (EPA; 425 mg) and docosahexaenoic acid (DHA; 100 mg). Vitamin E (15 IU), an antioxidant, is added to each gel capsule to prevent oxidation and preserve freshness. Each gel capsule also contains natural lemon oil and rosemary extract to enhance taste and freshness.

Intervention: Exercise
Description: The exercise intervention is facility-based aerobic exercise training on a treadmill, stationary bicycle or elliptical trainer performed 3 times a week for 12 weeks. The duration of each training session is determined for each woman based on the weekly total energy expenditure goal and workload required to achieve her prescribed exercise heart rate. Women train at 50-60% heart rate reserve (HRR) for the first month and then increase intensity to 60-70% HRR. To ensure that women train at their prescribed exercise heart rates, women wear Polar Heart Rate Monitors while exercising. The exercise counselor overseeing each exercise session records each participant's exercise heart rate every 5-10 minutes to document that she is in her target heart rate range.
