The Claim
In elderly men over 70 years of age, a protein intake of 1.6 g/kg/day for 10 weeks increases knee-extension peak power by approximately 26.6 W compared to a protein intake of 0.8 g/kg/day, which results in no significant change, independent of energy balance.
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.
Elderly men over 70 who consume 1.6 grams of protein per kilogram of body weight daily for 10 weeks gain about 26.6 watts of peak power in knee extension, while those consuming 0.8 grams per kilogram per day show no significant change, regardless of total calorie intake.
See the scientific wording
In elderly men over 70, a protein intake of 1.6 g/kg/day for 10 weeks improves knee-extension peak power by approximately 26.6 W, while a 0.8 g/kg/day intake results in no significant change, independent of energy balance.
Eating more protein gives the body more building blocks for muscle, which lets muscles grow larger and stronger. Larger muscles can produce more force quickly, so the legs can push harder during fast movements like extending the knee.
What the research says
1 studyIn older men, eating twice as much protein as usual for 10 weeks made their leg strength stronger by about 26.6 watts, even if they weren’t eating enough calories. The group eating the normal amount didn’t get stronger.
