First normative reference of standing long jump indicates gender difference in lower muscular strength of Macedonian school children

Abstract

Background: This is the first study to publish the normative reference values for assessment of the level of muscular strength through the "standing long jump" test carried out on a large sample of Macedonian school children. The normative values encompass a wide span of years (6 -18). Methods: The research was realized in a large sample of 12618 school children at the age of 6 to 18 years from Macedonia. The sample was divided in 14 groups, according to chronological age and each age group was divided into two subgroups according to the criteria of gender. For estimation of the morphologic characteristics, the following anthropometric measures have been applied: body height in standing position (cm), body weight (kg), as well as the body mass index (BMI). Children aged 6 or above were invited to take a standing long jump test. Results: Boys show statistically better results in all age categories in the standing long jump test than girls, and these differences become bigger with the increase of age, especially after the 14th year (p < 0.000). Results from the linear regressive analysis show that the constants in predicting the standing long jump are similar both in boys and in girls. However, the age coefficient in boys is two times higher than that in girls. The Body Mass Index, as a factor, influences two times more in boys in predicting the standing long jump, which indicates that the body size in boys has bigger inverse impacts on the results of the standing long jump than that in girls. Conclusion: Normative reference values shall provide proper assessment and interpretation of the level of muscular strength of the Macedonian school children in terms of the age and gender, accurate detection of progress of an individual as well as undertaking preventive measures and level of intervention.

Physical fitness percentiles of Polish children aged 4–7 years

“…and in the Portuguese population 98.0 cm 45 . This tendency is also observed when comparing own results with the results from Macedonia 47 and Southern Spain 48 . Correlating the presented parentel values in terms of power to the European data 49 a higher level of strength (standing long jump) of Polish girls and preschool boys is also found.…”

A Comparative and Corelative Study On Body Composition and Motor Performance of 14 Years Old Boys of Four Different Altitudes of Darjeeling District

“…It was found from the study of Paul (2013), the average standing broad jump of 14 year old male students of 24 Pgs (N), West Bengal was 171.37 cm with S.D of 15.92. and for Macedonian school children it was 180.5 cm with S.D of 28.07 (Gontarev et al, 2014). Analysing the result of standing broad jump it may be concluded that the present study has close proximity to Paul (2013).…”

Contribution of Leg Flexibility, Limb Length, Leg Power for the Split Leap Skills of Rhythmic Gymnastics Athletes

“…The joints of the feet are measured by recording images and analyzing by sitting straight with the knees touching the floor and doing maximum flexion of the tapered leg (point) and extension of the knee leg in the same way. Measuring leg power using a standing long jump is a measurement instrument that can see the power criteria for a certain age [18]. Judging of the Split Leap Movement (with criteria by nationally licensed Jury) with the criteria according to motion as discrete motion.…”
