The Claim
The decline in maximum muscle power with aging is initially driven by reductions in force production (torque) in young and middle-aged adults, but in older adults (≥60 years), it becomes increasingly associated with concurrent declines in both force and movement velocity, indicating a shift in the underlying physiological mechanisms of muscle aging.
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.
As people get older, their muscles lose power — but how that happens changes over time. Younger adults mostly lose strength, while older adults lose both strength and speed, meaning different things go wrong in the body as we age.

What the research says
1 studyThe study shows that younger adults lose muscle power mostly because they get weaker, but older adults lose it because they get weaker AND slower, which matches the claim.
