The Claim
In untrained young men performing unilateral calf raises, executing partial-range-of-motion repetitions beyond the point of failure in full-range-of-motion sets increases muscle thickness by 0.16% per set, which is twice the rate of increase compared to traditional full-range-of-motion sets (0.08% per set), when total volume-load is equated.
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 untrained guys do calf raises and keep going with shorter movements after they can't do full ones anymore, their muscles grow twice as fast per set compared to stopping at failure with full movements — as long as the total workout load is the same.
See the scientific wording
In untrained young men performing unilateral calf raises, partial-range-of-motion repetitions beyond full-range-of-motion failure increase muscle thickness 0.16% per set, which is twice as efficient as traditional full-ROM sets that increase thickness by 0.08% per set, when total volume-load is equated.
When the calf muscle is stretched while still pushing hard, the internal spring-like protein titin gets pulled tight and sticks to the muscle's contractile fibers. This tension triggers signals that cause the muscle to add more repeating units called sarcomeres end-to-end, making the muscle fibers longer and thicker over time.
