Flax Oil Plus Resistance Training May Combat Age-Related Muscle Loss and Inflammation

Age-related muscle loss and chronic inflammation represent major barriers to healthy aging. This University of Saskatchewan clinical trial investigated whether combining flax oil supplementation with resistance training could provide superior benefits compared to exercise alone for combating these issues in older adults.

The randomized controlled study enrolled 60 older participants over a 4-month period in 2007. Participants underwent progressive resistance training while receiving either flax oil containing alpha-linolenic acid (ALA) or placebo supplements. ALA is an omega-3 fatty acid abundant in flaxseed that may reduce production of pro-inflammatory cytokines involved in muscle protein breakdown.

Researchers measured changes in muscle mass, strength, and inflammatory markers to determine if the combination approach offered advantages over resistance training alone. The study specifically targeted sarcopenia and systemic inflammation, two interconnected processes that accelerate functional decline in aging populations.

While detailed results from this completed trial aren't provided, the research addresses a critical question in longevity science: whether anti-inflammatory nutrition can enhance exercise benefits. The combination approach represents a practical intervention strategy, as both resistance training and omega-3 supplementation are accessible to most older adults.

This research contributes to understanding how targeted nutrition might optimize exercise adaptations in aging populations. The findings could inform evidence-based approaches for maintaining muscle mass and reducing chronic inflammation, two key determinants of healthspan and functional independence in later life.
