Exercise countered age-linked gene control changes in mice
Aging increased the involvement of gene-regulating proteins at more than 100,000 DNA sites in mouse hearts; endurance exercise opposed most increases.Aging increased the involvement of gene-regulating proteins at more than 100,000 DNA sites in mouse hearts; endurance exercise opposed most increases.

What changedExercise countered most age-related increases in gene-regulating protein engagement at DNA sites in mouse hearts
The catchThe molecular findings describe gene regulation, not benefits for heart function or lifespan
