The brand new legitimacy and precision out of jump tests was in fact prior to now analyzed in children by a number of article writers [31,thirty-two,38]. Each kid jumped for point of an effective standstill. In the overall performance of one’s leaps, children had been asked so you can flex its knee joints making use of their arms inside front of these, synchronous to your ground, then to swing both of your arms, push off vigorously and you will plunge so far as you can, looking to home employing legs together with her and to remain upright. The test is actually performed 3 times and scored 
inside the centimetres. The latest longest plunge length try submitted.
Muscular fuel of fingers.
Chest electricity are evaluated of the a front put away from an effective baseball (0.5 kg) , that has been recognized as becoming a valid and you will reputable try . Pupils had been questioned to sit on to the floor using their ft aside as well as their back leaning from the wall surface, against the brand new assistance where the basketball would be to end up being thrown. Golf ball happened having a couple of hands and delivered alongside the body from the chest height, after that vigorously tossed pass as far as possible, maintaining wall structure get in touch with. The longest place from three, once the counted from the point between your wall plus the basic get in touch with area of your own ball toward soil, are registered in the centimetres.
Flexibility.
Stylish and you may low back self-reliance was in fact analyzed by the Stand Come to decide to try [17,18,20,21,23,25,33,34], whoever reliability and you may authenticity was basically prior to now analyzed throughout the literary works [thirty-two,41]. Inside a seated condition the help of its knee joints longer and their ft put completely facing a vertical assistance, children attained send over the computing line as far as you are able to with the hands at the same top. The exact distance hit because of the its hand with the nearest centimetre are submitted while the get, utilizing the number of your own feet given that zero, with the intention that people level that failed to reach the leg are believed bad and you will people level not in the foot is actually experienced confident.
Fixed balance.
The new condition harmony test was used inside earlier knowledge so you can dependably glance at balance capability in children [25,28]. Pupils removed their shoes and you may placed their on the job the pelvis. While controlling into popular feet, the fresh totally free leg are flexed within knee, therefore the foot occured near the butt from the hands of the same front. People had an extra to practice their balancing prior to beginning the newest test. Following, pupils endured on their popular toes to possess a maximum of 30 s. Time is registered whenever pupils moved its help base otherwise whenever it forgotten contact between your back of your own non-supporting feet in addition to their butt.
Mathematical 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.
