Model za povećanje eksplozivne snage donjih ekstremiteta kod adolescenata

Abstract

Cilj ovog istraživanja bio je da se utvrde efekti petnaestonedeljnog ekperimentalnog tretmana na motoričke sposobnosti ispitanika koji su činili studenti Univerziteta u Novom Sadu, uzrasta 20-21 godine. Nakon podele celokupnog uzorka, eksperimentalnu grupu je činilo 48, dok je kontrolnu grupu činilo 53 ispitanika. Ispitanici iz eksperimentalne grupe bili su podvrgnuti petnaestonedeljnom eksperimentalnom tretmanu u vidu kompleksnog treniga, koji je bio sproveden 3x nedeljno, dok su se ispitanici kontrolne grupe uz svakodnevne aktivnosti obavezno bavili sportskorekreativnim aktivnostima 2-3 puta nedeljno. Razlike između grupa na inicijalnom i finalnom merenju utvrđene su pomoću multivarijatne analize varijasne (MANOVA), univarijatne analize varijanse (ANOVA) i diskriminativne analize, za sve tretirane varijable. Za utvrđivanje efekta primenjenog eksperimentalnog tretmana (trenažnog modela), primenjena je multivarijatna analiza kovarijanse (MANCOVA), za ceo sistem primenjenih varijabli, dok je pojedinačna razlika kod analiziranih varijabli utvrđena primenom univarijatne analize kovarijanse (ANCOVA). U prvom delu analizirane su razlike motoričkih varijabli, dok su u drugom delu prikazane razlike varijabli eksplozivne snage donjih ekstremiteta. Nakon sprovedenog eksperimentalnog tretmana, a na osnovu rezultata multivarijatne analize kovarijanse, može se zaključiti da postoji statistički značajna razlika između ispitanika E i K grupe u motoričkim varijablama (p = .000), kao i uvarijablama eksplozivne snage (p= .000). Na osnovu svega, može se zaključiti da je primenjeni eksperimentalni tretman bio uspešan i dao željene efekte na poboljšanje ciljanih motoričkih sposobnosti.

The aim of this study was to determine the effects that a fifteen-week experimental treatment has on the motor abilities of respondents who were students of the University of Novi Sad, aged 20-21 years. After dividing the entire sample, the experimental group consisted of 48, while the control group consisted of 53 respondents. Respondents from the experimental group were subjected to a fifteen-week experimental treatment in the form of complex training, which was conducted 3 times a week, while the respondents of the control group were engaged in daily sports and recreational activities 2-3 times a week. Differences between the groups regarding initial and final results were determined using multivariate analysis of variance (MANOVA), univariate analysis of variance (ANOVA) and discriminant analysis, for all treated variables. To determine the effect of the applied experimental treatment (training model), multivariate covariance analysis (MANCOVA) was applied for the whole system of applied variables, while the individual difference in the analyzed variables was determined using univariate covariance analysis (ANCOVA). The first part analyzes the differences of motor variables, while the second part presents the differences of the explosive power variables of the lower extremities. After the conducted experimental treatment, and based on the results of multivariate analysis of covariance, it can be concluded that there is a statistically significant difference between respondents of E and C groups in motor variables (p = .000), as well as in explosive power variables (p =.000). Based on all this, it can be concluded that the applied experimental treatment was successful and gave the desired effects on the improvement of target motor abilities.
