The Claim
The dose-response relationship between weekly resistance training volume and muscle hypertrophy remains consistent regardless of whether the study duration is short-term or long-term.
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.
Increasing the amount of resistance training per week leads to greater muscle growth, and this relationship does not change whether the training lasts a few weeks or several months.
See the scientific wording
The dose-response relationship between weekly resistance training volume and muscle hypertrophy is maintained across study durations (short-term and long-term).
Doing more resistance training each week increases the physical stress on muscle fibers, which turns on a molecular switch that tells the muscle to build more protein. This leads to bigger muscle fibers over time, no matter how long the training lasts.
What the research says
3 studiesWhen older people do more sets of leg exercises each week, they tend to build more muscle — even if they didn’t respond to doing just one set. This shows that doing more training usually leads to more muscle growth, no matter if you’ve been training for a few weeks or a few months.
More weekly weight training leads to more muscle growth, no matter if you’ve been training for a few weeks or a few years — the rule stays the same.
More weekly weight training leads to bigger muscles, and this stays true whether you train for a few weeks or many months — the study found this pattern holds up across many different experiments.
