The Claim
In skeletal muscle tissue of young adult humans, eight weeks of high-intensity interval training leads to widespread DNA hypomethylation at 14,516 differentially methylated positions, indicating a broad epigenetic response to endurance exercise.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Doing intense interval workouts for 8 weeks can change how your genes are switched on or off in your muscles — and this study says it affects over 14,000 spots in your DNA.
See the scientific wording
In skeletal muscle of young adults, 8 weeks of high-intensity interval training induces widespread DNA hypomethylation at 14,516 differentially methylated positions, indicating a broad epigenetic response to endurance exercise.
What the research says
1 studyThe study found that intense exercise training changed chemical tags on DNA in young adults' muscles, and the number of these changes matches exactly what the claim says.
