The Claim
Resistance training at 80% one-repetition maximum with either 1-minute or 3-minute rest intervals produces significant quadriceps hypertrophy and strength gains in young, recreationally active adults over 10 weeks.
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.
Young adults who perform resistance training at 80% of their maximum lift capacity with either 1-minute or 3-minute breaks between sets experience measurable increases in quadriceps muscle size and strength after 10 weeks.

Lifting heavy weights repeatedly with enough total sets and reps causes muscle fibers to experience strong pulling forces and buildup of metabolic byproducts. This triggers a cellular signal that tells the muscle to make more contractile proteins, which accumulate over time and make the muscle fibers thicker.
What the research says
1 studyLifting heavy weights (80% of your max) twice a week for 10 weeks makes your quads bigger and stronger, whether you rest for 1 minute or 3 minutes between sets—though resting longer gives you a bit more muscle growth.
