Combined effects of exercise and omega-3 on cholesterol?

beating heartResearchers from Texas Woman’s University, in Denton looked for synergism.

Here’s what they found.

First, the details.

  • 11 sedentary, nonsmoking men with normal blood sugar levels were assigned to perform rest and exercise before and during omega-3 fatty acid supplementation.
  • Exercise consisted of 3 consecutive days of treadmill walking at 65% maximum oxygen consumption for 60 minutes.
  • Omega-3, 4.55 grams/day was taken for 42 days.

And, the results.

  • Exercise was associated with significant reductions in total cholesterol (-9.2%) and triglyceride (-32.4%) concentrations after exercise.
  • There was no evidence of a synergistic effect of exercise and omega-3 supplementation on cholesterol levels.

The bottom line?

“Exercise and omega-3 fatty acid supplementation do not synergistically improve serum lipids and lipoproteins, but rather independently affect the metabolism of lipids and lipoproteins, concluded the authors.

Both are important as part of a comprehensive strategy to manage lipids and prevent heart disease.
