The Claim
Resistance training induces significant improvements in muscular strength and body composition in adults aged 90 and older.
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.
Adults aged 90 and older who perform resistance training experience measurable increases in muscular strength and favorable changes in body composition.
See the scientific wording
Resistance training induces significant improvements in muscular strength and body composition in adults aged 90 and older.
Lifting weights pulls on muscles with force, which tells muscle cells to build more protein and grow stronger. This same pulling also signals the body to use sugar more efficiently, pulling it out of the blood and into muscles for energy. As muscles get bigger and use more energy, the body burns fat to fuel them, leading to less body fat and more strength.
What the research says
2 studiesOlder people, even those 90 and up, who did strength exercises with resistance bands got stronger and lost body fat — even without special supplements. This proves lifting weights helps the very old stay healthier.
This study found that older women, even in their 70s and 80s, got stronger and lost fat from lifting weights — and age didn’t make the benefits smaller. So it’s very likely that people over 90 would see similar improvements.
