The Study
Lengthened Partial Repetitions Elicit Similar Muscular Adaptations as a Full Range of Motion During Resistance Training in Trained Individuals
This study is like a fair test where each person used one arm to do full reps and the other to do half-reps, and scientists measured how much each arm grew. Because it was a randomized and controlled experiment, we can say the results likely show a real comparison between the two types of reps — but only for arm muscles in people who already lift weights.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
This study checked if doing partial reps that stretch the muscle work as well as full reps for building bigger and stronger arms.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes, the result is meaningful—both methods work similarly well for building muscle and endurance in trained people.
- 2After 8 weeks, both full and partial reps that stretch the muscle increased arm size by 1.8–3.0 mm and improved 10-rep strength equally.
