The study included 30 subjects (age: 23.43 +- 6.73 years, height: 173.85 +- 8.10 and weight: 71.47 +- 9.13 kg), which are all training 9-pin bowling for competition purposes (17 women and 13 men). From the sample 2 subjects were lefthanded and remaining 28 were right-handed. We performed isokinetic testing on a SMM dynamometer (Maribor, Slovenia), at a speed of 60 °/s in a concentric mode for quadriceps and hamstring muscles. Subject reached the values of the maximum torque in quadriceps left (L) = 218.3 +- 43.63 Nm (PTQ/BW 3.12 +- 0.7 Nm/kg), right (R) = 194.63 +- 52.27 Nm (PTQ/BW 2.78 +- 0.76 Nm/kg) and hamstrings L = 90.17 +- 25.29 Nm (PTQ/BW 0.85 % 0.26 Nm/kg), R = 116.37 +- 30.29 Nm (PTQ/BW 1.66 +- 0.46 Nm/ kg). Hamstring to quadriceps ratio (HQR) was on the left leg 0.41 +- 0.08 and on the right leg 0.61 +- 0.14. Bilateral asymmetry of quadriceps muscles was 18 +- 0.17 % and hamstrings 22 +- 0.08 %. The paired t test was conducted and statistically significant differences were found between the maximum torque of the L and R quadriceps p = 0.000, L and R hamstring p = 0.000, L and R quadriceps PT/BW p = 0.000, L and R hamstring PT/BW p = 0.000 and L and R HQR p = 0.000Namen raziskave je bil predstaviti maksimalne vrednosti sprednje in zadnje stegenske mišice kegljačev ter asimetrije sprednje in zadnje stegenske mišice med obema nogama. V raziskavo je bilo vključenih 30 merjencev (starost 23.43 +- 6.73 leta, višina 173.85 +- 8.10 in teža 71.47 +- 13.09 kg), ki se tekmovalno ukvarjajo s kegljanjem (17 žensk in 13 moških) in od katerih sta bila 2 merjenca levičarja, ostalih 28 pa desničarjev. Opravili smo izokinetično testiranje na napravi SMM (Maribor, Slovenija) na hitrosti 60°/s v koncentričnem načinu za sprednjo in zadnjo stegensko mišico. Kegljači so dosegli vrednosti maksimalnih navorov sprednje stegenske mišice L = 218.3 +- 43.63 Nm (PTQ/BW 3.12 +- 0.7 Nm/kg), D = 194.63 +- 52.27 Nm (PTQ/BW 2.78 +- 0.76 Nm/kg) ter zadnje stegenske mišice L = 90.17 +- 25.29 Nm (PTQ/BW 0.85 +- 0.26 Nm/kg), D = 116.37 +- 30.29 Nm (PTQ/BW 1.66 % 0.46 Nm/kg). Razmerje med zadnjo in sprednjo stegensko mišico (HQR) znaša na levi nogi 0.41 +- 0.08 in na desni nogi 0.61 +- 0.14. Bilateralne asimetrije sprednje stegenske mišice znašajo 18 +- 0.17 % in zadnje stegenske mišice 22 +- 0.08 %. S parnim t-testom smo zaznali statistične razlike med maksimalnim navorom leve in desne sprednje stegenske mišice p = 0.000, leve in desne zadnje stegensko mišico p = 0.000, levim in desnim maksimalnim navorom sprednje stegenske mišice glede na telesno maso p = 0.000, levim in desnim maksimalnim navorom zadnje stegenske mišice glede na telesno maso p = 0.000 in med levim in desnim razmerjem med zadnjo in sprednjo stegensko mišico p = 0.000TEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za šport
