The Claim

Exercise training in men increases mitochondrial gene expression in skeletal muscle and adipose tissue, and these increases are correlated with alterations in plasma sulfur-containing amino acids.

How it works
1 study reviewed
In plain English

In men, regular exercise increases the activity of mitochondrial genes in muscle and fat tissue, and these changes occur alongside measurable shifts in sulfur-containing amino acids in the blood.

See the scientific wording

Exercise training in men increases mitochondrial gene expression in both skeletal muscle and adipose tissue, and these changes are correlated with alterations in plasma sulfur-containing amino acids, suggesting a systemic link between redox metabolism and tissue-level metabolic adaptation.

Why this might work

When a man exercises, his muscles and fat cells produce more reactive molecules that stress the cells. This stress triggers a shift in sulfur-based chemicals in the blood, pulling building blocks into antioxidant production. As the body adapts to regular exercise, it uses these chemicals more efficiently, reducing their levels in the blood. This improved balance tells the cells to turn on genes that make more energy-producing factories inside the cells, making both muscle and fat tissue better at using energy.

    When men exercised regularly, their muscles and fat tissues turned on more genes that help make energy, and at the same time, the levels of certain sulfur-based chemicals in their blood changed in a way that matched those gene changes—showing the body’s energy systems are working together.
