Correlation between the successfulness of carrying out specific police topography tasks and mobility abilities of Police Academy students

Abstract

The degree of correlation between the successfulness of carrying out specific police topography tasks and mobility abilities was tested on a group of 26 randomly sampled student members of Police Academy Orienteering Club which had competed in orientation trekking (orienteering) on the national level. The experiment was conducted in a multivariate space consisting of 12 different variables - a criterion one, defined as the successfulness of carrying out specific police topography assignments (Points), and a system of eleven predictor variables describing mobility abilities which are hypothetically for the most part responsible for the manifestation of man’s locomotion being a function of the observed criterion. Out of a number of statistical analyses, the multiple regression analysis was used. On the basis of obtained criterion dependency model and statistically significantly related predictors, a mathematical model of the equation of criterion prediction was defined. Two models were separated which describe a criterion statistically significantly with approximately 52% of valid variance and consist of the following predictors: critical velocity (VcritAER) and mechanical efficiency (MECHeffAER) of movement by running in the anaerobic regime of strain, critical velocity (VcritANAER) and energy efficiency (ENEReffANAER) time needed to cover the distance of 20 meters (Let20m) with maximal velocity of movement by running, and maximal consumption of oxygen as the measure of aerobic power of organism (VO2rel ). The first function of the equation of model of criterion prediction has the following form: Points= - 157.364 - 15.5634 * ENEReffANAER + 488.005 * Let20m - 152.222 * MECHeffAER + 306.43 * VcritAER + 188.233 * VcritANAER - 19.4185 * VO2rel. The second function of the equation of model of criterion prediction has the following form: Points = - 1191.76 - 16.4457 * ENEReffANAER + 510.031 * Let20m - 21.0847 * MECHeffAER + 43.5481 * VcritAER + 200.929 * VcritANAER.

Na slučajnom uzorku od 26 studenata članova orijentiring sekcije Policijske akademije, koji su se na nacionalnom nivou takmičili u orijentacionom trčanju (orijentiringu), proveren je stepen povezanosti između uspešnosti rešavanja specifičnih zadataka iz policijske topografije i motoričkih sposobnosti. Ispitivanje je izvedeno nad multivarijatnim prostorom sačinjenim od 12 različitih varijabli - kriterijumske, definisane kao uspešnost rešavanja specifičnih zadataka iz policijske topografije (Bodovi) i sistema od jedanaest prediktorskih varijabli, koje su opisivale motoričke sposobnosti koje su hipotetski u najvećoj meri odgovorne za manifestaciju lokomocije čoveka u funkciji posmatranog kriterijuma. Od statističkih analiza korišćena je Multipla regresiona analiza. Na osnovu dobijenog modela zavisnosti kriterijuma i statistički značajno vezanih prediktora definisan je matematički model jednačine predikcije kriterijuma. Izdvojena su dva modela koji su kriterijum opisivale statistički značajno sa oko 52% valjane varijanse, a činili su ih sledeći prediktori: kritična brzina (VcritAER) i mehanička efikasnost (MEHefikAER) kretanja trčanjem u aerobnom režimu naprezanja, kritična brzina (VcritANAER) i energetska efikasnost (ENERefikANAER) kretanja trčanjem u anaerobnom režimu naprezanja, vreme potrebno da se maksimalnom brzinom kretanja trčanjem savlada distanca od 20 m (Let20 m) i maksimalna potrošnja kiseonika kao mera aerobne moći organizma (VO2rel). Prva funkcija jednačine modela predikcije kriterija ima sledeći oblik: Bodovi = -157.364 - 15.5634 * ENERefikANAER + 488.005 * Let20 m - 152.222 * MEHefikAER + 306.43 * VcritAER + 188.233 * VcritANAER + 19.4185 * VO2rel. Druga funkcija jednačine modela predikcije kriterija ima sledeći oblik: Bodovi = -1191.76 - 16.4457 * ENERefikANAER + 510.031 * Let20 m - 21.0847 * MEHefikAER + 43.5481 * VcritAER + 200.929 * VcritANAER.
