The Claim

Short repetition duration during resistance exercise induces greater ribosome biogenesis in rat gastrocnemius muscle than long repetition duration, as demonstrated by increased total RNA and 18S+28S rRNA levels, which correlate with muscle hypertrophy, suggesting that ribosome production is a key mechanism for muscle growth under short-duration resistance exercise protocols.

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.

How it works
1 study reviewed
In plain English

When rats lift weights with quick, short reps, their leg muscles make more of the cellular machinery needed to grow bigger, compared to slow, long reps—and this might be why quick reps help muscles grow more.

What the research says

  1. Study: Effects of repetition duration on skeletal muscle hypertrophy in a rat model of resistance exercise.

    Short, quick lifts made rat leg muscles grow bigger and made more ribosomes (cellular machines that build muscle), while slow, long lifts didn’t. So short reps are better for muscle growth via ribosome production.
