The Claim
Moderate intensity continuous training is associated with a small but significant increase in mitofusin 2 (MFN2) protein expression in human skeletal muscle, with a pooled standardized mean difference of 0.40 [95% CI: 0.08, 0.73] across six studies, indicating that enhanced mitochondrial fusion dynamics may contribute to improved mitochondrial quality and function following 2–16 weeks of training in adults.
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 steady, moderate exercise regularly might help your muscle cells' energy factories work better by boosting a protein that helps them merge and stay healthy.

What the research says
1 studyThe study looked at the same type of exercise mentioned in the claim and found that it slightly increases a protein called MFN2, which helps mitochondria fuse together and work better.
