Red blood cell membrane omega-3 fatty acid levels and physical performance: Cross-sectional data from the MAPT study

This cross-sectional study found that participants with a low omega-3 index had worse performance-based test results of physical function than people with a high omega-3 index, but this association did not reach statistical significance once confounders were controlled for. Studies looking at the over-time associations between PUFA status and physical performance changes may shed more light on this topic.
