A lifetime of motion: New research reveals endurance exercise trains the immune system to fight smarter
- Long-term endurance training makes the immune system more efficient, adaptable and less inflammatory, challenging the idea that intense exercise suppresses immunity.
- In older adults who exercise, these key immune cells are more adaptable, produce a less aggressive inflammatory response, and are metabolically more efficient, allowing them to function without burning out.
- The study found that endurance-trained individuals have far better regulation of chronic, low-grade inflammation, which is linked to many age-related diseases.
- Even when key cellular communication pathways were blocked in tests, the natural killer cells from exercisers continued to function, while cells from sedentary individuals failed.
- The research positions lifelong endurance exercise as a powerful investment in "immune resilience," offering a new dimension to healthy aging beyond cardiovascular health.
