The Claim
Lengthened partial range of motion resistance training and full range of motion resistance training result in similar changes in upper arm and thigh muscle cross-sectional area after a 12-week intervention, with estimated differences near zero and p-values above an adjusted significance threshold of 0.005, indicating no meaningful difference in muscle growth between the two training methods.
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 partial reps with extended muscle stretch and full reps with normal movement build your arm and thigh muscles about the same amount over 12 weeks — neither one is clearly better than the other.
See the scientific wording
Lengthened partial range of motion resistance training and full range of motion resistance training produce similar changes in upper arm and thigh muscle cross-sectional area over a 12-week period, with estimated differences close to zero and p-values exceeding the adjusted significance threshold of 0.005, suggesting no meaningful difference in muscle growth between the two methods.
What the research says
1 studyThis study found that lifting weights through a partial range (just the stretched part) and lifting through the full range made arms and thighs grow about the same amount after 12 weeks — so neither method is clearly better for building muscle.
