Abstract


Purpose : To identify changes and relationships in the fat mass and obesity associated (FTO) gene polymorphism, body composition, and physical fitness from childhood to adolescence over a three-year period spanning elementary school to middle school (2015-2018)

Methods : A total of 84 male student participants were divided into two groups based on FTO genotype: aa+at (group A) and tt (group T) and tracked down. Body composition, cardiovascular endurance, flexibility, muscle strength, power, and other characteristics were measured in the two groups in both 2015 and 2018, respectively, and the changes over the three-year period were analyzed and compared.

esults : Increases in height and weight did not differ significantly between the two groups, but body mass index (BMI) was significantly higher in group A (p=.035). With regard to physical fitness, there was no significant difference in flexibility, but cardiovascular endurance, strength, and power were significantly higher in group T (p<.001, p=.063, and p=.040, respectively).

Conclusion : Group A is more likely to become obese than group T because of their lower level of physical fitness and increased BMI relative to group T. This result supports previous studies showing that group A has a relatively low level of physical activity and a greater tendency to eat fatty foods as compared with group T. Therefore, we suggest that the FTO gene polymorphism should be identified early and that students educated on diet and physical activity to help prevent adult obesity.
