How your genes shape strength, endurance, and recovery.
Part of injury and recovery risk is genetic - variants in genes like COL1A1 affect tendon and ligament resilience, which is why some bodies tolerate high mileage and others break down.
If you've ever walked out of a dim room into blazing sunshine and immediately sneezed - once, twice, maybe three times - you have what scientists cheerfully call the photic sneeze reflex. It's harmless, it's surprisingly common, and it runs in families. There's even a wonderful backronym for it: ACHOO - Autosomal-dominant Compelling Helio-Ophthalmic Outburst.
Your raw DNA sequence never changes, but the interpretation of your DNA report can become outdated as science advances. New genes get linked to conditions, risk models improve, and testing technology gets more precise. This doesn't mean your original test was wrong; it means genetics is a fast-moving field, and periodic report updates or reinterpretation can keep your health in
Recovery capacity is partly genetic - how quickly you clear exercise stress and rebuild depends on genes affecting inflammation and stress-hormone clearance.
Exercise genetics helps explain why the same workout produces different results in different people. Genetic factors affecting fitness influence muscle growth, endurance, recovery speed, and how strongly the body responds to training, though genetics works alongside effort, consistency, and lifestyle rather than replacing them.
