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.

In plain English

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.

Why this might work

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.
