The Claim
Lengthened partial repetitions and full range of motion resistance training produce equivalent improvements in upper-body muscle strength and endurance, as measured by 10-repetition maximum performance, when performed to momentary failure over an eight-week supervised training period in resistance-trained individuals.
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.
If you train your upper body with either full-range movements or just the stretched part of the movement, you'll build the same amount of strength and endurance over eight weeks, as long as you push each set to failure.
See the scientific wording
Lengthened partial repetitions and full range of motion resistance training elicit similar improvements in muscle strength-endurance, as measured by 10-repetition maximum performance on upper-body exercises. Following an eight-week supervised training program in resistance-trained individuals, statistical comparisons of unilateral lat pulldown strength showed no meaningful differences between conditions. These findings suggest that both training modalities produce equivalent gains in muscular endurance and strength when performed to momentary failure.
What the research says
1 studyThe study found that doing partial lifts with a longer stretch and full-range lifts for eight weeks resulted in the exact same strength and endurance gains. Both methods work equally well for building upper body muscle performance.
