The Claim
In young, recreationally active adults performing high-intensity resistance training at 80% one-repetition maximum, higher volume load causes greater increases in quadriceps cross-sectional area, regardless of rest interval duration (1 minute or 3 minutes).
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.
Among young adults doing intense weight training at 80% of their maximum lift, increasing the total amount of weight lifted leads to larger muscle growth in the quadriceps, whether rest periods are 1 minute or 3 minutes.
See the scientific wording
In young, recreationally active adults performing high-intensity resistance training at 80% one-repetition maximum, volume load is the primary driver of quadriceps hypertrophy, as greater increases in cross-sectional area (12.9–13.1%) were observed when volume load was higher, regardless of whether rest intervals were 1 minute or 3 minutes.
Lifting heavier total weight over time stretches and fatigues muscle fibers, which turns on a molecular switch that tells the muscle to build more contractile proteins. These proteins stack together, making the muscle fibers thicker and increasing the overall size of the quadriceps muscle.
What the research says
1 studyWhen lifting heavy weights, how much total weight you lift over time matters more for building muscle than how long you rest between sets. The study showed people grew more muscle when they lifted more total weight, no matter if they rested 1 minute or 3 minutes.
