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).
