The Claim
Six weeks of high-volume resistance training increases integrated non-myofibrillar protein synthesis rates by 69.3% relative to high-load resistance training in trained young men.
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.
In trained young men, six weeks of high-volume resistance training results in a 69.3% higher rate of non-contractile muscle protein synthesis compared to high-load resistance training.
See the scientific wording
Six weeks of high-volume resistance training increases integrated non-myofibrillar protein synthesis rates by 69.3% relative to high-load training in trained young men, suggesting a greater metabolic adaptation in non-contractile muscle components under high-volume conditions.
When muscles are worked with many repetitions using lighter weights, the cells inside the muscle fill with calcium, which turns on specific signaling pathways that tell the cell to make more proteins for energy production and cell maintenance, not for muscle contraction. This happens over time and results in a bigger increase in these metabolic proteins compared to lifting heavy weights with fewer reps.
What the research says
1 studyWhen trained guys lift lighter weights with more reps, their muscles make more proteins that help with energy and cell functions, compared to lifting heavy weights with fewer reps. This study proved it by measuring those exact proteins.
