The plyometric method is ranked among the most commonly used methods for fitness volleyball training. It leads to the development of explosive strength and reactive velocity of the muscular system based on improving the CNS response and the power required to absorb the stress when landing. The study was of longitudinal type, involving two measurements, an initial measurement for all subjects to determine the initial level of motor ability, and a final measurement where the effects of the experimental program were studied after a programmed experimental process to develop specific motor skills of the analyzed sample of subjects. The entire study was conducted on a sample of 72 senior subjects, which were divided into two sub-samples, one sub-sample comprised of the experimental group and the other comprising the control group. The primary objective of the research was to test the influence and effect of special treatment of kinesiological activities based on plyometric exercises on the motor skills of the subjects.
Cilj ovog istraživanja je bilo utvrđivanje valjanosti testova specifičnih vještina u fudbalu. Uzorak je bio sastavljen od 80 fudbalera muškog pola uzrasta 13-16 godina (M=15,1 god; s=1,1; raspon=3,83; min=13; max=16,83). Određena je valjanost 12 testova fudbalskih vještina iz SoccerTutor Skill Tester baterije testova. Prvo je utvrđena kriterijska valjanost testova, odnosno istovremena valjanost kao poseban tip kriterijske valjanosti. Koeficijent istovremene valjanosti je obuhvatio korelacije rezultata testova i rezultata subjektivne sudijske procjene. Statističku značajnu povezanost sa kriterijem pokazalo je 8 od ukupno 13 varijabli. To su bili testovi za procjenu kotrole lopte u kretanju, specifične agilnosti u fudbalu, i po jedan test specifične kontrole lopte i test za procjenu elevacijske preciznosti dodavanja. Konstrukt valjanost testova je utvrđena primjenom metode razlike između poznatih grupa. U ovom radu ispitanici su grupisani u tri grupe (dominantni, dobri, slabi) na osnovu subjektivne trenerske procjene. Na osnovu rezultata analize varijanse utvrđena je statistički značajna razlika između grupa na osnovu rezultata 6 testova. To su testovi slalom sa loptom, slalom bez lopte, osmice sa loptom, dugo dodavanje, trčanje sa loptom povratno i žongliranje stopalima.
The aim of the study was to examine the influence of training processes modeled after the School of Sport of Faculty of Pedagogy, on changes in the status of the foot arch, motor abilities and morphological characteristics of preschool and young school children. The study was of longitudinal character. The experimental training program was conducted from 1st September 2018 till 1st December 2018. The follow-up included 92 subjects in total, divided into two sub-samples: one comprised of experimental group subjects, 45, and the other, control group of 47 subjects. The analysis of the status of the foot arch was performed with a Digital Computer Podoscope. For the assessment of the motor abilities a battery of motor abilities was used, modeled after Bala, Stojanović, Stojanović, (2007). Measurement of morphological characteristics was performed with the application and adherence to the International Biological Program. Using the MANOVA and χ2 test, the results obtained after the final measurement show statistically significant changes in motor abilities, morphological characteristics, and the status of the arch of the foot in children.
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.
