Abstract

We examined the impact of aerobic exercise on morphological characteristics and agility in elementary school children. Anthropometric characteristics of the subjects were as follows: longitudinal skeletal dimension (body height, as well as the lengths of upper and lower extremities), circular skeletal dimension and body mass (mean circumference of the chest, the circumference of the thigh of an stretched leg, maximum circumference of the calf, body mass) and subcutaneous fat (skin thickness of the abdomen, thigh and calf). The agility was estimated by the envelope test, side steps and a eight with bending. For statistical analysis we employed the basic methods of descriptive statistics, while the discriminatory power of measurements was estimated by calculation of skewness and kurtosis of the data. Canonical correlation analysis was applied to explain the structure of the relationships between the two sets of data. The results of the analysis on this sample suggest that there is a strong linear relationship between morphological characteristics and agility at a multivariate level.

Highlights

It is well known that physical education in elementary schools has been facing, for a long time, a number of problems that adversely affect its efficiency
The present study examined the influence of morphological characteristics and motor skills on the results achieved in agility and explosive strength in the elementary school students, which would result in better results in physical education
The intervals of the minimum and maximum values of the results contained at least five standard deviations, indicating substantial scattering, i.e. the sensitivity of anthropometric measures

Summary

Introduction

It is well known that physical education in elementary schools has been facing, for a long time, a number of problems that adversely affect its efficiency. Physical education classes in secondary schools, according to some researchers [1,2], predominantly insist on the informatic component of the performance (learning motor skills), their exercises are usually not effective enough to develop the skills and characteristics which are the basic requirements for the changes of the quantitative and qualitative dimensions of students’ anthropological status. Since physical education is inadequately covered by the number of classes per week (two classes), the teaching is achieved through the low energy component, which is a major problem in achieving the goals and objectives of the physical education program [3]
