Down limb volatile electricity is examined by a lengthy jump shot [17,18,20,21,23,25,33,34,thirty six,37]

Brand new validity and precision regarding diving testing had been before analyzed in kids by a number of people [29,thirty two,38]. Each kid popped for distance off a good standstill. During the efficiency of jumps, college students had been questioned so you’re able to flex their legs employing palms for the front side of them, synchronous towards the soil, following to help you move both arms, push off vigorously and you can plunge as much as possible, seeking homes with regards to legs together also to remain straight. The test try did 3 times and you can scored when you look at the centimetres. The fresh new longest diving size was submitted.

Muscle electricity of one’s arms.

Upper body electricity are examined by a frontal throw of good basketball (0.5 kilogram) , that has been defined as getting a legitimate and you can reputable attempt . Pupils was asked to stay on the ground with regards to ft aside as well as their back leaning up against the wall structure, up against the newest direction where in actuality the golf ball were to getting tossed. The ball happened which have several hand and you can brought near to one’s body at boobs level, next intensely tossed pass so far as you’ll, keeping wall get in touch with. Brand new longest toss out of three, because the mentioned of the point between the wall together with very first get in touch with point of the basketball to your surface, is submitted inside the centimetres.


Cool and reasonable right back liberty were analyzed because of the Sit Arrived at test [17,18,20,21,23,25,33,34], whose precision and you will legitimacy was indeed previously analyzed from the literature [32,41]. Inside a sitting status due to their hips offered and their legs placed completely against a straight assistance, college students attained forward across the calculating line as much as you are able to employing possession at the same top. The distance hit because of the the give for the nearby centimetre is submitted because rating, with the amount of the feet due to the fact no, so that any measure that failed to achieve the foot is experienced bad and you may one measure outside the leg try noticed self-confident.

Fixed harmony.

The position harmony decide to try was applied for the earlier degree to dependably view harmony skill in children [twenty five,28]. Youngsters eliminated their shoes and you can set its on the job the hips. If you find yourself controlling towards the preferred foot, the fresh new free foot is actually flexed during the lower body, and foot was held near the backside because of the give of the identical front side. People got one minute to rehearse the controlling before you start new sample. After that, children endured on the common foot getting a total of 30 s. Day is filed when college students went their supporting legs otherwise when it lost contact within back of your non-supporting toes as well as their butt.

Mathematical analysis

To perform the analysis, the collected data were first screened for incorrect inclusions. When they were not plausible, records were excluded from the database if the correct information was unavailable. Anthropometric characteristics and all physical fitness information were expressed as the mean and standard deviation (SD) or standard error (SE) in the graphs and stratified by sex and age and by sex, age and BMI categories, respectively. The effects of sex, age and BMI categories and the interaction among these variables on anthropometric characteristics and physical fitness were tested using two-way analysis of variance (ANOVA) after evaluating the homogeneity of variance with Levene’s test. When significant differences were found, a Bonferroni post hoc test was evaluated implementing multiple comparisons to detect which variable means were significantly different from each other. Then, a simple linear regression equation was calculated for each sex and for each physical fitness parameter (including 6 to 11 age) to evaluate the difference between each BMI category. We compared the regression coefficients (?) of NW with those of other BMI categories (individually for males and females) to test the null hypothesis H0: ?NW = ?OB/NW/UW and to evaluate whether the dimension of a regression coefficient should be larger for one group than for another. All statistical analyses were performed by SAS, Release 9.4 (SAS Institute, Cary, NC, USA), with a significance set at p<0.05.
