The Claim
The gastrocnemius muscle produces reduced contractile tension when shortened due to its position on the descending limb of the length-tension relationship, and as a result, partial-range training at longer muscle lengths may be more effective for inducing hypertrophy; this mechanism could also extend to other bi-articular or pennate muscles such as the trapezius and pectoralis major.
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.
Your calf muscle doesn’t squeeze as hard when it’s too short, so doing exercises where it’s stretched might help it grow more. This could also be true for other muscles like your shoulders and chest.
See the scientific wording
The gastrocnemius muscle generates lower contractile tension at shortened lengths due to its position on the descending limb of the length-tension curve, making lengthened partial training more effective for hypertrophy; this mechanism may also apply to other bi-articular or pennate muscles like the trapezius and pectoralis.
What the research says
2 studiesThe study shows that lifting weights while stretching muscles more leads to more muscle growth, which supports the idea that exercises using a full stretch work better for building muscle.
The study found that doing calf raises with a stretch (long muscle position) builds more muscle than doing them with a short muscle position, which supports the main idea. But it only tested calf muscles, not shoulders or chest.
