The Claim
During 120 minutes of moderate-intensity cycling at approximately 60% of VO2 peak in healthy young adults, mitochondrial fatty acid translocase CD36 protein content increases by 63%, and this increase is significantly correlated with elevated rates of mitochondrial palmitate oxidation, suggesting CD36 plays a functional role in enhancing long-chain fatty acid transport into mitochondria during prolonged aerobic 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.
During two hours of moderate cycling, the amount of CD36 protein in muscle mitochondria increases by 63%, and this increase is directly linked to higher rates of fatty acid breakdown in mitochondria.

During prolonged cycling, muscle cells move a protein called CD36 to the surface of their energy factories, where it grabs fatty acids and shuttles them inside. This allows more fat to be burned for energy, and the amount of fat burned matches how much CD36 is present. At the same time, the energy factories become more sensitive to fatty acids, letting them process more fuel even when inhibitory signals are unchanged.
What the research says
1 studyDuring a long bike ride, muscle cells make more of a protein called CD36, and the more CD36 they make, the more fat they burn inside their energy factories — proving CD36 helps move fat into those factories to be used for energy.
