The Claim
Among men, peak power output during cycling is strongly positively correlated with lower-limb lean volume, indicating that larger leg muscles are associated with greater power generation.
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.
Men with bigger leg muscles can produce more power when cycling.
See the scientific wording
In men, peak power output during cycling is strongly positively correlated with lower-limb lean volume, indicating that larger leg muscles are associated with greater power generation.
Bigger leg muscles have more muscle fibers, so they can push harder. Some muscle fibers are fast and contract quickly. When you pedal a bike as fast as you can, both how hard you push and how fast you move your legs matter. Since bigger muscles give more pushing power, they lead to more overall power.
What the research says
1 studyStudy: Power output and muscle myosin heavy chain composition in young and elderly men.
The study found that men with bigger leg muscles were able to generate more power when cycling, with a very strong link between muscle size and power output.
