The Claim

Among Chinese Han adults undergoing 12 weeks of twice-weekly resistance training, individuals carrying the rs731236-AA genotype experience greater improvements in isokinetic leg strength and vertical jump power than those carrying the AG genotype, with this difference being more pronounced in women, indicating genotype-specific variations in neuromuscular adaptation to resistance exercise.

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.

Cause and effect
1 study reviewed
In plain English

People in China with a specific gene version (AA) who do leg workouts twice a week for 12 weeks get stronger and jump higher than those with a different gene version (AG), especially if they’re women.

See the scientific wording

In Chinese Han adults undergoing 12 weeks of twice-weekly resistance training, carriers of the rs731236-AA genotype show greater improvements in isokinetic leg strength and vertical jump power compared to AG carriers, particularly in women, suggesting genotype-specific differences in neuromuscular adaptation to resistance exercise.
