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.
Claim Language
Language Strength
probability
Uses probability language (may, likely, can)
The claim uses 'show greater improvements' and 'suggesting', which indicate likelihood or tendency rather than certainty. 'Show' implies observable difference, and 'suggesting' explicitly signals inference, not proof, placing it in the probability category.

Subject
Chinese Han adults undergoing 12 weeks of twice-weekly resistance training who carry the rs731236-AA or AG genotype
