The Claim
Among Chinese Han adults undergoing 12 weeks of resistance training, individuals carrying the rs1544410-CC genotype experience greater increases in upper limb bone mineral content than those carrying the CT genotype, with additional genotype-specific associations: males with the CC genotype show greater increases in lower limb muscle thickness, and females with the CC genotype show greater improvements in post-training power.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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 Chinese adults who lift weights for 12 weeks, people with a specific gene version (CC) tend to gain more bone in their arms than those with another version (CT). Men with this gene also tend to build thicker leg muscles, and women with it tend to get stronger at explosive movements after training.
See the scientific wording
In Chinese Han adults undergoing 12 weeks of resistance training, carriers of the rs1544410-CC genotype demonstrate greater gains in upper limb bone mineral content compared to CT carriers, with additional associations in males for lower limb muscle thickness and in females for post-training power improvements.
What the research says
1 studyStudy: VDR Gene Polymorphisms and Inter-Individual Variability in Response to Resistance Training.
The study found that people with the CT version of this gene, not the CC version, got more bone strength from training — which is the opposite of what the claim says. It did find CC helped men build leg muscle, but not in the way the claim described for bones or women.
