The Study
Greater Gastrocnemius Muscle Hypertrophy After Partial Range of Motion Training Performed at Long Muscle Lengths
This study shows that doing calf raises in a certain part of the movement might lead to bigger calf muscles in young women. But we can't say for sure that it caused the growth because we don’t know all the details about how the study was done. It’s like seeing a pattern, but not having all the puzzle pieces to prove why it happened.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Young women did calf raises in different ways for 8 weeks. Some moved their ankles the whole way, some only the first half, and others only the second half. Scientists measured how much their calf muscles grew.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes, the difference is meaningful because doing part of the movement led to over four times more growth than doing the final part.
- 2The group that did only the first half of the calf raise (ankle from −25° to 0°) had the most muscle growth: 15.2% in the inner calf.
- 3The full move gave 6.7% growth.
- 4The last half of the move gave only 3.4% growth.
