The programmes of prevention and control of cardiovascular diseases should decrease the influence of risk factors and improve diagnostics and therapy of cardiovascular diseases.
The aim of this study was to determine the effects of innovative and traditional physical education classes on motor abilities of children of younger school age. The sample consisted of 42 students (26 males and 16 females), aged 8 (M = 8.54), second grade of the Elementary School "Laza Kostić" in Kovilj near Novi Sad. The experimental group consisted of 22 students (52.3%) involved in a twelve-week innovative exercise program whose characteristics were changing the content of the class and the fact that it consisted of teaching units that with their form, scope and intensity focus on development of these abilities, while the control group consisted of 20 (47.7%) students who attended traditional physical education classes in accordance with the current curriculum of the Ministry of Education of the Republic of Serbia. Motor skills were assessed using six tests (Sprint from a high start at 20 meters - speed; Long jump from the board - explosive power of the lower extremities; Backwards polygon and Skipping and pulling - whole body coordination; Test T for agility and Running 4x10 meters - agility). The results showed that there is a statistically significant effect on all tested variables of motor skills in students who attended innovative classes (Sprint from a high start at 20 meters) (p = .00, ES = -.14); Long jump from the board (p = .,00, ES = .,71); Back polygon (p = .00 ES = -.44); Skipping and dragging (p = .00, ES = -.20); T test for agility (p = .01, ES = -0,22); Running 4x10 meters (p = .00; ES = -.43), while this was not the case with students who attended traditional physical education classes.
The aim of this study was to examine the differences in motor competence among children of different school ages, as well as whether there is a negative trend in the decline of these values with increased age. The research was conducted in a school environment, the sample consisted of 151 male and female children, age 7-11 years, divided into four approximately equal subsamples: first grade children N=36 (7.4±0.3 years, Mean±SD), second grade children N=41 (8.5±0.3 years, Mean±SD), third grade children N=40 (9.4±0.3 years, Mean±SD) and fourth grade children N=34 (10.4±0.3 years, Mean±SD). The Körperkoordinations test (KTK) assesses the coordination of the whole body and is intended for children aged 5-14 years. The test is internationally standardised and consists of 4 subtests from which the following variables emerged: single-leg hopping, walking backwards, two-legged lateral jumping, lateral movement platforms and Total KTK. The multivariate analysis of variance (MANOVA) revealed statistically significant differences between children of all ages in all tested variables, in the total (P=.00) and individual (p=.00) system of variables. These findings also indicated a negative trend of declining motor competence of children with increasing age. A similar trend was observed in the individual variables of the KTK battery. The increased involvement of physical education teachers and children in physical education classes is recommended in order to increase the development of children's motor competence through regular physical activities on a daily basis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
