The Claim
Resistance training performed at longer resting muscle lengths induces greater skeletal muscle hypertrophy compared to training at shorter resting lengths, a process potentially mediated by amplified exercise-induced muscle damage and metabolic stress at extended positions.
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.
Building muscle works best when you stretch it out during your exercises. For example, doing standing calf raises stretches the calf muscle more than seated ones, which leads to bigger muscle growth.
See the scientific wording
Training skeletal muscles at longer resting lengths promotes greater hypertrophic adaptations than training at shorter resting lengths. When the gastrocnemius muscle is stretched across the knee joint during standing calf-raises, it experiences significantly more growth than when it is shortened during seated calf-raises, supporting the principle that exercise-induced muscle damage and metabolic stress are amplified at extended muscle lengths.
What the research says
1 studyStudy: Triceps surae muscle hypertrophy is greater after standing versus seated calf-raise training
The study found that doing calf raises while standing (which stretches the calf muscle) builds more muscle than doing them while sitting (which shortens the muscle). This proves that stretching the muscle during exercise leads to better growth.
