The question about 'sports genes' in children is understandable but requires scientific caution. MyBody-X DNA tests can identify variants linked to muscle fiber type (e.g., ACTN3), endurance (e.g., ACE), or recovery, but their predictive power for children is limited. Genetics accounts for only a modest fraction of athletic performance; environment, training, nutrition, and psychology play larger roles. Few longitudinal studies validate these markers for pediatric populations. These consumer tests are not clinical diagnostics and should not be used to steer children into specific sports or to label them as 'unsuitable.' A responsible approach treats results as interesting but non-deterministic. For performance concerns or health issues, consult a sports medicine physician or pediatrician.
