Exercise Blocked 55% of Age-Related Muscle Changes

Deep dive: https://open.substack.com/pub/staycuriousmetabolism/p/scientists-just-discovered-how-exercise?r=40ekz2&utm_campaign=post&utm_medium=web&showWelcomeOnShare=true Muscle biopsies showed that regularly trained older adults lacked about 55% of the age-related gene-expression changes usually observed in aging. Many of these changes involved mitochondria and muscle metabolism, suggesting that consistent exercise may preserve important features of muscle biology during aging. For the full mechanisms, limitations, and nuance, watch the long-form breakdown linked above. #HealthyAging #ExerciseScience #MuscleHealth #Mitochondria #LongevityScience #GeneExpression #StayCurious
