Association of Mitochondrial DNA Levels in Peripheral Blood Leukocytes With Physical Performance in Older Adults

Key Points

• The research aims to explore how mitochondrial DNA levels in blood cells correlate with physical performance in older adults.
• Measured mitochondrial DNA copy number (mtDNA-CN) in peripheral blood leukocytes.
• Evaluated physical performance through standardized tests for older adults.
• A significant association was found between leukocyte mtDNA-CN levels and physical performance.
• Higher mtDNA-CN levels were linked to better physical performance metrics.
