EFFECT OF EXERCISE ON THE FUNCTIONAL ABILITIES OF SECONDARY SCHOOL STUDENTS

The aim of the research is to study the effects that exercise models have on the functional abilities of secondary students. The sample consisted of high school students in Krusevac, ages 15 and 16, enrolled in full-time physical education and the training process in additional physical education classes. A total of 112 subjects was divided into two sub-samples: The first sub-sample of 56 subjects comprised the experimental group. Here, students are enrolled in regular physical education classes and training three times a week to realize a model of motor exercises (flexibility) in the process of conditioning in additional physical education classes.The second sub-sample of 56 subjects, included in regular physical education classes only, constitutes the control group of respondents. The sample of variables consisted of: a vital lung capacity, pulse rate after load, Margaria test of anaerobic capacity.We analyzed the results of the T-test of functional ability between initial and final measurement of subjects. After analysis of the obtained results, it is concluded that there is a statistically significant difference in the pulse rate after loading (FPPOP .000) and Margaria test (FMARG .000).

EFFECTS OF EXPERIMENTAL MODEL OF EXPLOSIVE STRENGTH IN REGULAR PHYSICAL EDUCATION CLASSES

.The study was conducted with the goal to determine the effects of explosive strength training on the transformation of motor skills and functional abilities during regular physical education classes, among students of primary schools. The sample of examinees consisted of 64 pupils from Niš, 14 years old. Experimental group comprised of 32 examinees, selected for the training of experimental model of explosive strength in the main part of regular physical education classes, three times per week, in duration of 45 minutes, for the period of eight weeks. One half of these classes was dedicated to regular PE curriculum, while the other half to an experimental program of explosive strength, in duration of eight weeks. Control group also comprised of 32 examinees, who attended regular physical education classes, three times per week in duration of 45 minutes, for the period of eight weeks. Following motor skill were assessed: coordination (two tests), sprint speed (two tests), repetitive strength (two tests), and explosive strength (two tests). Following functional abilities were assessed: pulse frequency after physical activity, Margaria test, and vital lung capacity. For processing of data, variance and covariance analysis were applied. Study results showed that experimental group of examinees achieved better results in motor skills and functional abilities, as well as that there were statistically significant effects at the final testing
