There is strong evidence for a positive association between CRF and cluster of PF with AP in cross-sectional studies ; and evidence from longitudinal studies for a positive association between cluster of PF and AP ; the relationship between muscular strength and flexibility with AP remains uncertain
Physical fitness ( PF ) is a construct of health- and skill-related attributes which have been associated with academic performance ( AP ) in youth .
This study aim ed to review the scientific evidence on the association among components of PF and AP  in children and adolescents .
Physical activity and obesity mediate the association between childhood motor function and adolescents’ academic achievement
The global epidemic of obesity and physical inactivity may have detrimental implication s for young people ’s  cognitive function and academic achievement . This prospect i ve study investigated whether childhood motor function predicts later academic achievement via physical activity , fitness , and obesity . The study sample included 8,061 children from the Northern Finl and Birth Cohort 1986 , which contains data about parent-reported motor function at age 8 y and self-reported physical activity , predicted cardiorespiratory fitness ( cycle ergometer test ) , obesity ( body weight and height ) , and academic achievement ( grade s ) at age 16 y.  Structural equation models with unst and ardized ( B ) and st and ardized ( β ) coefficients were used to test whether , and to what extent , physical activity , cardiorespiratory fitness , and obesity at age 16 mediated the association between childhood motor function and adolescents ’ academic achievement . Physical activity was associated with a higher grade -point average , and obesity was associated with a lower grade -point average in adolescence . Furthermore , compromised motor function in childhood had a negative indirect effect on adolescents ’ academic achievement via physical inactivity ( B = –0.023 , 95 % confidence interval = –0.031 , –0.015 ) and obesity ( B = –0.025 , 95 % confidence interval = –0.039 , –0.011 ) , but not via cardiorespiratory fitness . These results suggest that physical activity and obesity may mediate the association between childhood motor function and adolescents ’ academic achievement . Compromised motor function in childhood may represent an important factor driving the effects of obesity and physical inactivity on academic underachievement
