The Claim
The fractional quantification method for resistance training volume, which assigns a weight of 0.5 to indirect sets, is statistically superior to total and direct quantification methods in predicting muscle hypertrophy and strength gains in young, mostly male adults.
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.
A specific way of measuring resistance training volume that gives indirect sets half the weight of direct sets predicts muscle growth and strength increases more accurately than other measurement methods in young, mostly male adults.
See the scientific wording
The fractional quantification method for resistance training volume—assigning 0.5 weight to indirect sets—is statistically superior to total or direct methods for predicting muscle hypertrophy and strength gains in young, mostly male adults.
When you do exercises that indirectly work a muscle, the muscle still gets stretched and squeezed, but less than when you do exercises that target it directly. This difference in how hard the muscle is worked affects how much it grows and how much stronger it gets. Counting indirect exercises as half as effective matches how much they actually stress the muscle.
What the research says
1 studyThis study found that when counting how much weight training someone does, giving partial credit to exercises that indirectly work a muscle (like push-ups for the chest) works better than only counting exercises that target it directly. This method predicted muscle growth and strength gains more accurately.
