PROCENA DUŽINE I FREKVENCIJE KORAKA PRI TRČANJU RAZLIČITIM BRZINAMA KOD MUŠKARACA I ŽENA
Sažetak
Uspešnost u toku trčanja zavisi od mnogobrojnih faktora, a jedni od najbitnijih jesu dužina i frekvencija koraka. Prvi cilj ovog istraživanja je procena razlika dužine i frekvencije koraka između muškaraca i žena pri različitim brzinama trčanja. Drugi cilj jeste ispitivanje povezanosti morfoloških karakteristika muškaraca i žena sa dužinom i frekvencijom koraka. U ovom istraživanju su učestvovale dve grupe od 37 rekreativnih trkača (22 muškaraca i 15 žena). Ispitanici su trčali na tredmilu noseći na svakom članku noge dva prenosiva Prosense akcelerometra. Protokol je podrazumevao 10 minuta trčanja i to: 3 minuta zagrevanja na 8 km/h, po jedan minut trčanja na 8, 10, 12 i 14 km/h (korišćeno za dalje analize) i 3 minuta trčanja na 8 km/h. Glavne varijable koje su se koristile su dužina i frekvencija koraka. Rezultati su pokazali da su žene imale veću frekvenciju koraka od muškaraca pri gotovo svim brzinama trčanja (p < 0,05), ali u dužini koraka nije bilo razlike između muškaraca i žena. Takođe, kod muškaraca su dobijene visoke i statistički značajne negativne korelacije visine i frekvencije koraka (r >-0,59<-0,66), kao i niske do umerene pozitivne korelacije visine sa dužinom koraka (r >0,17<0,46). Kod žena su dobijene niske do umerene negativne korelacije visine i frekvencije koraka (r >-0,28<-0,43) i takođe niske do umerene pozitivne korelacije visine sa dužinom koraka (r >0,34<0,52). Rezultati istraživanja kao i moderna tehnologija korišćena u ovom radu bi značajno unapredila trenažni proces trkača rekreativaca.
