Combined effects of exercise and omega-3 on cholesterol?
Researchers 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.
