The Claim
Acute resistance exercise consisting of 20 sets of 10 repetitions of leg extensions and flexions at 75% of one-repetition maximum increases myofibrillar and sarcoplasmic protein synthesis by two- to threefold in the exercised leg of young, healthy men, demonstrating a robust anabolic response to high-volume resistance training in human skeletal muscle.
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.
Doing a tough leg workout with lots of sets makes your leg muscles start building new proteins much faster—2 to 3 times more than usual—right after the workout.
See the scientific wording
Acute resistance exercise (20 sets of 10 leg extensions and flexions at 75% 1RM) increases myofibrillar and sarcoplasmic protein synthesis by two- to threefold in the exercised leg of young, healthy men, indicating a robust anabolic response to high-volume resistance training in human skeletal muscle.
What the research says
1 studyThe study found that intense leg exercise boosts muscle protein creation by two to three times, just like the claim says.
