All the way down limb explosive power is evaluated of the an extended diving test [17,18,20,21,23,25,33,34,thirty six,37]

Brand new legitimacy and accuracy regarding dive tests have been before evaluated in kids by several article authors [29,32,38]. Each child jumped for range off a great standstill. During the results of jumps, people was indeed requested in order to flex its hips with regards to arms inside front side ones, synchronous toward crushed, next in order to move both of your arms, push off strenuously and you can plunge so far as you’ll, trying to belongings with regards to foot together also to remain straight. The exam is did 3 x and scored from inside the centimetres. The brand new longest dive length is registered.

Muscular energy of the arms.

Torso electricity are evaluated by a frontal put from a great basketball (0.5 kilogram) , that has been identified as getting a legitimate and reputable decide to try . Youngsters was basically asked to sit on to the ground with regards to feet apart in addition to their back leaning contrary to the wall surface, up against the fresh recommendations the spot where the ball were to feel thrown. The ball occured having several give and you may put near to you during the boobs peak, following strenuously tossed forward in terms of it is possible to, keeping wall get in touch with. This new longest place away from three, since counted by the distance involving the wall structure plus the basic get in touch with area of the basketball on the soil, is actually submitted within the centimetres.


Hip and you may low right back freedom were evaluated by the Remain Reach decide to try [17,18,20,21,23,twenty five,33,34], whoever precision and you will legitimacy were in past times assessed on literature [thirty-two,41]. When you look at the a sitting reputation making use of their hips offered in addition to their feet placed solidly facing a straight assistance, people hit pass over the computing line in terms of possible making use of their hands at the same level. The exact distance achieved by the its give with the nearest centimetre was submitted given that rating, utilising the amount of the feet as the zero, so one scale that didn’t reach the leg are sensed negative and you can any size outside of the toes try experienced positive.

Fixed equilibrium.

The fresh updates harmony try was used in prior studies so you’re able to easily see equilibrium capability in kids [25,28]. Students removed their sneakers and place their practical the hips. If you’re balancing on the prominent foot, the 100 % free feet try flexed from the knee, and the legs happened close to the buttocks of the give of the same side. People had a moment to train the balancing before starting the fresh new attempt. After that, youngsters stood on their well-known foot to possess a total of 31 s. Big date is recorded whenever children moved its help feet otherwise when it destroyed get in touch with between your back of low-support toes and their buttocks.

Statistical investigation

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.
