Birthweight, body composition, and motor performance in 7- to 10-year-old XXXX .

@entity1 @entity26 @entity1386
AIM: The aim of this study was to analyse the influence of birthweight on motor performance and body composition in @entity1 . Further, we investigated whether associations between birthweight and motor performance changed after adjustment for current height, body mass index (BMI), @entity1386 ( @entity1386 ), and % body fat. METHOD: A total of 483 @entity1 (251 males and 232 females) aged 7 to 10  years (mean 8.78, SD 1.0y) born in Vit  ria Santo Ant  o (northeast Brazil) were sampled. Motor performance was operationalized using different physical fitness components and gross motor coordination. Physical fitness was measured by handgrip strength, muscle endurance, explosive power, flexibility, agility, running speed, and maximal @entity26 consumption (VO2max ). Gross motor coordination was evaluated by means of the K  rper Koordination Test f  r Kinder (KTK). RESULTS: Positive correlations between birthweight and height, BMI, and @entity1386 were found. Birthweight was positively correlated with handgrip strength and negatively correlated with 20-meter sprint time, even after controlling for age, height, BMI, @entity1386 , and % body fat. Birthweight was negatively associated with relative VO2max (mL/kg/min); however, the association was no longer significant after inclusion of BMI or @entity1386 in the model. INTERPRETATION: Birthweight significantly predicted height, BMI, @entity1386 , and performance in strength and velocity tests, but did not influence gross motor coordination.
