SEX DIMORPHISM OF HAND-GRIP ENDURANCE IN HEALTHY AND YOUNG PERSONS

The aim of this work is to determine sex dimorphism in endurance of hand grip force in referent population of healthy and young persons. In the study participated 48 examinees, among whom 23 were women and 25 were men. Muscle force of hand's musculus flexor was measured by using the method of isometric dynamometry, where we used the standard hand grip-test. By multivariant analysis we determined that there is a significant difference between men and women in endurance of hand grip force, in relation to parameters of force level (F sub(max), F sub(80%max), F sub(50%max) and F sub(30%max)), for Wilk's Lambda 0.082, F=189.439, p=0.000, so as for the time aspect of expressing the given force (tF sub(80%max), tF sub(50%max) and tF sub(30%max)), for Wilk's Lambda 0.270, F=13.533, p=0.000, and for parameters of force momentum as a direct endurance measure (ImpF sub(80%max), ImpF sub(50%max) i ImpF sub(30%max) and ImpF sub(80%rel), ImpF sub(50rel) and ImpF sub(30%rel)) for Wilk's Lambda 0.373, F=8.42, p=0.000 and Wilk's Lambda 0.406, F=7.33, p=0.000, respectively. Our results can be used as a criteria in analytics and diagnostics by evaluation of physical abilites in different populations, so as in sports.Original Abstract: Cilj ovog rada je utvrditi spolni dimorfizam izdrzljivosti u sili stiska sake kod referentne populacije zdravih i mladih osoba. U istrazivanju je sudjelovalo 48 ispitanika, i to 23 ispitanika zenskog i 25 ispitanika muskog spola. Misicna sila pregibaca prstiju sake je mjerena metodom izometricke dinamometrije, gdje je koristen standardizirani test - stisak sake. Multivahjantnom analizom je utvrdeno da postoji znacajna razlika u izdrzljivosti u sili stiska sake izmedu zenskog i muskog spola, i to u odnosu na parametre razine sile (F sub(max), F sub(80% max), F sub(50% max) i F sub(30% max)) za Wilks 'Lambda 0.082, F = 189.439, p=0.000, za vremenski aspekt iskazivanja date sile (tF sub(80% max), tF sub(50% max) i tF sub(30% max)) za Wilks 'Lambda 0.270, F=13.533, p=0.000, te za parametre impulsa sile kao direktne mjere izdrzljivosti (ImpF sub(80% max), ImpF sub(50% max) i ImpF sub(30% max) i ImpF sub(80% rel), ImpF sub(50% rel) i ImpF sub(30% rel)) za Wilks 'Lambda 0.373, F = 8.42, p = 0.000 i Wilks' Lambda 0.406, F=7.33, p=0000, respektivno. Dobiveni rezultati mogu koristiti kao kriteririji u analitici i dijagnostici pri procjeni fizickih sposobnosti kod razlicite populacije ljudi, kao i u sportu.
