The Claim
During repeated strength testing, both young and older adults exhibit transient increases in motor unit discharge rates that coincide with rapid, short-term gains in muscular strength.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When people of any age do strength exercises multiple times in a row, their muscles fire more intensely for a short while—and that’s when they get a quick boost in strength.

What the research says
1 studyStudy: Aging, resistance training, and motor unit discharge behavior.
When people do the same strength exercise over and over in a short time, their muscles get stronger quickly — and this study shows that happens because their nerves fire faster, even in older adults.
