The Study
Partial range of motion training elicits favorable improvements in muscular adaptations when carried out at long muscle lengths
This study shows that doing leg exercises in certain parts of the movement might be linked to bigger muscles in specific areas. But we can't say for sure that the exercise caused the change 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
This study looked at how different knee bend ranges during leg exercises affect muscle growth and strength in women who don’t usually train.

Key takeaways
Summary
Based on the study abstract and findings.
- 1If you want to grow specific parts of your leg muscles, doing exercises with a deep but not full knee bend might work better.
- 2Women who did partial knee extensions from 100° to 65° grew more muscle in certain parts of their quads.
- 3Those who trained from 65° to 30° didn’t grow much, just like people who didn’t train.
- 4Everyone got stronger in the exact range they practiced.
