The Claim
In older adults at risk of metabolic syndrome, both accentuated eccentric and maximal strength resistance training using elastic bands produce comparable gains in muscle mass (1.4–2.3%) after 16 weeks, and muscle hypertrophy is not significantly influenced by eccentric overload in this population.
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.
In older adults at risk of metabolic syndrome, 16 weeks of resistance training with elastic bands—whether focused on eccentric or maximal strength—results in the same increase in muscle mass, and the type of muscle contraction does not change the outcome.
See the scientific wording
In older adults at risk of metabolic syndrome, both accentuated eccentric and maximal strength resistance training using elastic bands produce comparable gains in muscle mass (1.4–2.3%) after 16 weeks, indicating that muscle hypertrophy is not significantly influenced by eccentric overload in this population.
When muscles are stretched and contracted under resistance, the physical force triggers signals inside muscle cells that activate pathways to build more muscle proteins. At the same time, improved glucose uptake and reduced inflammation create a better environment for muscle growth, allowing both types of training to produce similar increases in muscle mass.
What the research says
1 studyIn older adults with metabolic risks, using elastic bands for strength training—whether focusing on slow lowering or full movements—led to about the same amount of muscle gain after 16 weeks. So, one method isn’t better than the other for building muscle.
