The Study
Influence of full range of motion vs. equalized partial range of motion training on muscle architecture and mechanical properties
This study shows some links between how far you move your muscles during training and how they change. It’s not proof that one thing causes the other because we don’t know all the details about how the study was done.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Some men did leg exercises moving their knees all the way, others only partway, but for the same total time. Scientists checked how their muscles changed.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes, the results show that how you move during exercise changes how your muscles adapt.
- 2Moving the knee all the way increased muscle fiber length by 4.9% and strength per muscle size by 25.8%.
- 3Moving only partway increased muscle thickness by 7.8% and strength at certain angles by 17.7%.
