The Influence of a Six-month Athletics Treatment Incorporated in Physical Education Classes on Changes of Morphological Characteristics in Seven-year Old Boys

This paper analyses the efficiency of a six-month athletics treatment within physical education classes in the first form of elementary school and influence of this treatment on morphological characteristics. For this purpose, the sample of 179 male pupils age 7 was submitted to 14 anthropometric measures twice within a period of 6 months. An analysis of changes in the applied anthropometric measures was made by the algorithm and programme SSDIF. It has shown significant quantitative differences between 39 pupils of the experimental group (attending specially programmed physical education classes conducted in accordance with the current curriculum). Changes were expressed in higher values, especially in the length of the leg, in the knee diameter, shoulder width, height and weight of the body, and in smaller values, especially of the stomach skin-fold. The changes are a probable consequence to the quantitative adaptation to the athletics training and are expressed through five factors of changes.
