5, +0.6, +1.0, +0.4, +0.7 and +0.8 s from 6 to 11 years, respectively, p<0.012). Moreover, agility improved progressively from age class 6 to age class 11 in children of either sex (by a mean of -0.7 s in girls and -0.8 s in boys each year).
The amount of time needed to complete the test was significantly longer in OB girls and boys than in NW girls and boys (Fig 1a, 1aC and 1aD). In particular, OB girls aged 7, 8, 10 and 11 needed more time than their NW peers (+6.6, +9.6, +7.8 and +15.6%, respectively, p<0.001), as did OB boys aged 8 to 11 (+10.9, +8.2, +13.5 and +15.7%, respectively, p<0.001). Similarly, 11-year-old OW girls took longer to complete the test than NW girls (+6.2%, p = 0.0231), as did 9-, 10- and 11-year-old OW boys compared to NW boys (+5.2, +5.4 and +6.5%, respectively, p< 0.001). On the other hand, UW girls showed worse agility capacity than NW girls at 6 years old (+6.2%, p = 0.023), and UW boys showed worse agility capacity than NW boys at 8 and 9 years old (+7.5% and +9.9%, respectively, p<0.033).
The newest agility pit ranging from OB, OW and you will NW college students improved when you look at the teenagers compared to younger people (Fig 2a, 2aC and you can 2aD). Zero significant hill differences was indeed discovered ranging from NW people and other Bmi groups. Yet not, brand new hills determined for OB and you may OW guys was rather greater versus mountain determined for NW boys (p = 0.006 and you will p = 0.008, respectively).
Muscular strength of the lower limb.
Girls jumps were shorter than those of boys for each age class (-6.6 cm at 6 and 7 years old, https://datingranking.net/pl/bbwcupid-recenzja/ -7.2 cm at 8 years old, -7.6 cm at 9 years old, -7.9 cm at 10 years old and -8.9 cm at 11 years old, p<0.006). Muscular power of the lower limb was considerably greater in older children than in younger children (mean +6.9 cm in girls, and +7.3 cm in boys, per year). The peak improvement was observed between 7 and 8 years (+9.6 and +10.2 cm in girls and boys, respectively).
The recorded jump distance was shorter in OB and OW children than in NW and UW children for either sex (Fig 1a, 1aE and 1aF). In particular, OB girls jumped a significantly shorter distance than their NW counterparts at each age class (-9.3, -10.9, -10.0, -10.3, -12.7 and -13%, at 6, 7, 8, 9, 10 and 11 years old respectively, p<0.001), as did OB boys (-9.5, -11.6, -13.8, -14.4, -15.6 and -15.9%, respectively, p<0.001). OW girls jumped a shorter distance than NW girls at 7, 8, 9, 10 and 11 years old (-4.0, -4.1, -6.4, -7.5 and -8.6%, respectively, p <0.001), as did OW boys (-4.3, -6.2, -6.8, -7.3 and -7.6%, respectively, p <0.001). On the other hand, 8-year-old UW girls and boys jumped a significantly shorter distance than their NW counterparts (-3.3%, p = 0.033 and -4.9%, p<0.001, respectively).
Lower limb muscular power disparities among children of differing BMI categories were found to be wider in higher age classes than in lower age classes (Fig 2a, 2aE and 2aF). The slopes of the regression models calculated for OB and OW children were significantly lower than the slope calculated for NW children of either sex (p<0.001 and p = 0.002 for OB and OW girls, respectively, and p<0.001 for OB and OW boys). On the other hand, the regression slope for UW boys was significantly higher than that of NW boys (p = 0.015).
