In this randomized study, 79 post-menopausal Persian women were randomized to one of 4 groups: exercise + supplement, exercise alone, supplement alone, or control (neither exercise nor supplement). Measurements were taken at baseline, 12 weeks, and 24 weeks.
The fish oil was a standard formulation of 1,000mg omega 3 fatty acids, of which 180mg was EPA and 120mg was DHA. No placebo was offered. Adherence was by pill count and measurement of serum levels. Exercise (obviously no placebo there) consisted of 25-30 minutes sessions of walking or jogging 3-4 sessions per week at 45-55% of their individually calculated maximum heart rate for the first 12 weeks. During the second 12 weeks, the participants increased their exercise to 40-45 minutes of walking or jogging 4-6 sessions per week at 55-65% of their calculated maximum heart rate.
Today's take home point? The combination of exercise and fish oil is good for your bones (and heart). But you knew that already, didn't you?
