The Claim
Lactate exposure stimulates mitochondrial biogenesis in human skeletal muscle through reactive oxygen species (ROS) signaling, increasing mitochondrial mass and expression of lactate oxidation machinery.
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.
Lactate, a molecule produced during exercise, triggers the production of new mitochondria in human muscle cells and increases the presence of proteins that break down lactate, through a signaling process involving reactive oxygen species.
See the scientific wording
Lactate exposure may stimulate mitochondrial biogenesis in human skeletal muscle through reactive oxygen species (ROS) signaling, potentially increasing mitochondrial mass and expression of lactate oxidation machinery, though this mechanism remains unproven in vivo.
When lactate enters muscle cells, it is transported into mitochondria and converted into pyruvate, which generates small bursts of reactive oxygen species. These molecules activate signals that cause the cell to build more mitochondria and increase the proteins needed to burn lactate for energy.
What the research says
1 studyStudy: Intracellular Shuttle: The Lactate Aerobic Metabolism
This study says that lactate, made when you exercise, might tell your muscle cells to build more energy factories (mitochondria) by creating tiny bursts of reactive oxygen species—like a signal to grow. It’s not 100% proven yet in humans, but the evidence points in that direction.
