The Claim
Anabolic signaling pathways, proteolytic activity, autophagy, and ribosome biogenesis exhibit comparable molecular responses across differing training volumes, indicating that muscle growth potential is not proportionally amplified by increased volume.
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 more workout volume doesn’t necessarily make your muscles grow more—your body’s internal muscle-building signals stay about the same no matter how much you train.
See the scientific wording
Anabolic signaling pathways, proteolytic activity, autophagy, and ribosome biogenesis exhibit comparable molecular responses across differing training volumes, indicating that muscle growth potential is not proportionally amplified by increased volume.
When muscles are worked with resistance, mechanical stress and metabolic fatigue activate signaling pathways that build more protein-making machines called ribosomes and turn on protein synthesis. Once a certain level of effort is reached, these systems stop increasing even if the workout gets harder or longer. The muscle doesn't make more growth machinery beyond that point, so doing more sets or reps doesn't lead to more muscle growth at the cellular level.
What the research says
2 studiesEven when people did more reps and sets (higher volume), their muscles didn’t grow more because the body’s main muscle-building signals stayed about the same. More work didn’t mean more growth at the cellular level.
Study: Ribosome biogenesis and resistance training volume in human skeletal muscle
Even if you do more sets at the gym, your muscles don’t turn up their growth signals any higher—they respond about the same whether you do one set or three. So doing more doesn’t necessarily mean more muscle growth at the cellular level.
