The Claim
Endurance exercise in healthy young adults is associated with downregulation of mTOR, spliceosome, and circadian pathway genes and their associated chromatin accessibility across all muscle fiber types.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy young adults, endurance exercise is linked to reduced activity of genes involved in muscle growth and daily biological timing, along with decreased accessibility of the chromatin regions that control these genes in all types of muscle fibers.
See the scientific wording
Endurance exercise in healthy young adults is associated with downregulation of mTOR, spliceosome, and circadian pathway genes and their associated chromatin accessibility in all muscle fiber types, suggesting a broad suppression of anabolic and timekeeping processes after acute exercise.
After endurance exercise, muscle cells open and close specific regions of their DNA to turn off genes that build proteins and control daily body rhythms, while turning on genes that make energy from fat and sugar. This shift redirects the cell's resources away from growth and timing functions and toward producing more energy to recover from the workout.
What the research says
1 studyAfter a workout, the study found that muscle cells turned on many genes to make more energy, not turned them off like the claim says. So the claim that exercise shuts down growth and body clock genes is not supported.
