1, -18.6, -26.9, -32.9, -39.6, -42.6 cm from 6 to 11 years, respectively, p<0.024). Muscular power of the upper limb increased from age class 6 to age class 11 in both girls and boys (by a mean of +36.8 and +41.7 cm per year, respectively). A peak was observed between 7 and 8 years old (+46.3 and +54.6 cm in girls and boys, respectively).
The distance covered by the thrown ball increased gradually from lower to higher BMI categories (Fig 1b, 1bG and 1bH). In particular, OB girls threw the ball significantly farther than NW girls at 6, 7, 8, 9, 10 and 11 years old (+9.3, +12.3, +10.5, +12.3, +9.3 and +12.3%, respectively, p<0.001), and OB boys threw the ball significantly farther than NW boys at 6, 7, 8, 9 and 10 (+10.9, +9.3, +6.3, +8.5 and +8.8%, p<0.001). Similarly, OW girls threw farther than NW girls at 6, 7, 8, 9, 10 and 11 years old (+9.9, +5.8, +5.7, +5.0, +4.8 and +6.2%, respectively, p<0.001), and OW boys threw farther than NW boys at 7, 8, 9, 10 and 11 (+5.9, +4.7, +5.1, +4.6 and +6.2%, respectively, p <0.001). Finally, UW girls scored significantly lower than NW girls at 7, 8, 9, 10 and 11 years old (-6.4, -8.9, -8.8, -8.5 and -6.6%, respectively, p <0.001), as did UW boys (-5.7, -7.5, -10.6, -7.5 and -5.7%, respectively, p <0.001).
The brand new pit for the muscle stamina of your arms one of youngsters belonging to various lbs updates categories was better for the teenagers than inside younger kids (Fig 2b, 2bG and you can 2bH). OB women and you may OW guys presented a notably higher linear regression slope than just NW young children, correspondingly (p = 0.005 and uberhorny you can p = 0.011). On the other hand, UW offspring shown notably reduced mountains than NW girls and you may guys (p = 0.003 and you will p = 0.011, respectively).
Flexibility.
Girls obtained higher Sit Reach scores than boys at each age class (+2.8, +3.5, +4.4, +5.3, +5.3, +5.9 cm from 6 to 11 years, respectively, p<0.027). Moreover, there was no significant difference in flexibility scores obtained by girls of differing age groups; on the other hand, scores were found to be significantly lower for older boys than for younger boys (by a mean of -0.8 cm each year).
Flexibility was partially influenced by BMI status (Fig 1b, 1bI and 1bJ). OB girls showed greater flexibility capability at 6 years old and lower capability at 9 years old (+107.1 and -100.0%, p<0.004) than NW girls, while OW girls were significantly less flexible than NW girls at 8, 9, 10 and 11 years old (-48.3, -56.7, -86.2 and -113.8%, respectively, p<0.005). On the other hand, BMI was found to have less impact on the flexibility of boys: only 9-year-old OB boys and 8-year-old OW boys performed significantly worse than their NW peers (-81.5%, p = 0.021 and -93.3%, p = 0.045, respectively).
Additionally, it was observed that the flexibility gap between children of differing BMI categories was greater in older children than in younger children, especially in girls (Fig 2b, 2bI and 2bJ). Indeed, only the slopes calculated for OB and OW girls were significantly different from those of their NW peers (p = 0.002 and p<0.001, respectively).
Static balance.
Balance capacity was found to be better in girls than in boys at each age class (+2.9, +3.0, +3.1, +2.8, +2.0, +1.9 s from 6 to 11 years old, respectively, p<0.015) and to increase by age in both sexes (by a mean of +1.9 s in girls and + 2.1 s in boys each year). A peak was observed between 7 and 8 years old (+3.3 and +3.2 s in girls and boys, respectively).
