The Claim
Resistance training performed every other day for 10 days increases daily myofibrillar protein synthesis rates by approximately 11-12% in adults aged 50–70 years, regardless of whether their daily protein intake (1.0 g/kg body mass) comes primarily from animal or plant sources.
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 adults aged 50 to 70, performing resistance training every other day for 10 days increases the rate of muscle protein synthesis by 11-12%, whether their daily protein comes from animal or plant sources.
See the scientific wording
Resistance training performed every other day for 10 days increases daily myofibrillar protein synthesis rates by approximately 11-12% in adults aged 50–70 years, regardless of whether their daily protein intake (1.0 g/kg body mass) comes primarily from animal or plant sources, indicating that short-term muscle anabolic adaptation to exercise is not dependent on protein source in this population.
When muscles are stretched and pulled during resistance exercises, the physical force triggers molecular signals that turn on the protein-making machinery in muscle cells. This causes the cells to build more contractile proteins every day, and the amino acids from food get used to make these proteins, leading to stronger muscles over time.
What the research says
1 studyDoing leg exercises every other day for 10 days made older adults’ muscles rebuild faster—by about 11–12%—no matter if they got their protein from meat or plants. The source didn’t matter for this short-term muscle boost.
