The purpose of the diploma was to find out how some of the morphological characteristics and some of the motor skills determine the success of standing triple jump at athletes aged 12 to 15 years. We also wanted to know how the influence of the morphological characteristics and the motor skills on standing triple jump varies within three age categories.
The study included pupils of three different age categoires aged 10 to 14 years. All the pupils in this study are members of the athletic clubs. The results of the measured morphological characteristics and the motor tests were taken into statistical processing. Measurements and tests were carried out under the same conditions and at the same time for all pupils.
Based on the results, we found out that the morphological characteristics of body height and leg length have a good connection with the result of standing triple jump. While calf skinfold and thigh skinfold have a negative correlation. Among the motor skills 60m running, standing broad jump, t-test, sit ups, standing heavy ball throw and sitting heavy ball throw have extremly good connection with the result of standing triple jump. The results also confirm that the degree of connectedness of morpohological characteristics and motor skills with standing triple jump within age categories varies. Otherwise the degreee of connetions of the more powerful variables remains the same. While in less influential variables, the degree of connection is less firmly. One of the main reasons for changes in connectivity is the entry into the period of accelerated growth, marked by the demolition of movable patterns and worse intermuscular and intramuscular coordination.
