“…In a recent study , same motor performance test (Eurofit) was applied on the 12-year-old girls, more differences between the RAE groups of girls were found, where relatively older girls had outperformed their relatively younger classmates in six out of eight motor tests (static strength, balance, the speed of limb movement, flexibility, abdominal muscular endurance, and arm and shoulder muscular endurance, respectively). Similar to Nakata et al (2017), this study did not find significant RAE in motor performance tests in 15-year-old girls, confirming their findings that RAE is more evident for boys than girls in adolescence.…”
