The latest legitimacy and you can reliability off diving testing was in fact in the past evaluated in children by a number of authors [29,thirty-two,38]. Each kid jumped to have range out of an effective standstill. When you look at the efficiency of one’s leaps, youngsters was in fact questioned so you’re able to flex the legs using their possession when you look at the top of them, synchronous with the soil, after that to move both arms, push-off strenuously and you can plunge in terms of you’ll, seeking to homes employing feet together with her and stand straight. The test are performed 3 times and scored within the centimetres. The latest longest plunge duration is actually filed.

Muscular energy of the palms.

Chest strength is evaluated by a frontal toss out of a beneficial basketball (0.5 kilogram) , which has been defined as are a legitimate and you will reputable sample . Children was indeed expected to sit on the ground employing feet apart and their back-leaning from the wall structure, up against the fresh direction where the ball would be to become tossed. The ball happened having a couple of hands and you may put next to the human body at bust level, upcoming strenuously tossed give in terms of you can easily, keeping wall structure get in touch with. New longest place out-of three, due to the fact counted by the range within wall surface additionally the basic contact area of basketball to your surface, was registered within the centimetres.

Freedom.

Stylish and you can lower right back independency had been evaluated from the Stand Arrive at take to [17,18,20,21,23,25,33,34], whose reliability and you can validity had been previously assessed on the literary works [thirty-two,41]. In the a seated condition employing legs longer and their feet set firmly facing a vertical help, youngsters achieved pass along https://datingranking.net/pl/angelreturn-recenzja/ side measuring line so far as you can easily using their hands in one height. The exact distance attained from the their hands toward nearest centimetre try recorded once the score, with the quantity of your own feet as the no, so as that any level you to definitely don’t get to the foot is actually felt negative and people size beyond the leg is noticed confident.

Static balance.

The reputation balance attempt was used from inside the prior studies to easily look at harmony capability in children [twenty-five,28]. Children removed their footwear and you will place its on the job the pelvis. When you’re controlling towards the popular foot, the fresh totally free base is actually flexed from the knee, and foot happened near the butt because of the hand of the same top. Pupils got an additional to practice its controlling prior to starting brand new try. Next, children stood on their popular foot getting a maximum of 31 s. Date try registered whenever students gone its support base otherwise when it missing get in touch with between the heel of the low-supporting leg as well as their butt.

Analytical 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.
