ISOKINET EXERC SCI , 2000, n° 8, p. 213-215 Doc n°: 100065 Localisation : Documentation IRR Descripteurs : KA43 - ISOCINETISME The purpose of this research was to compare isometric values (O°s-1) with isokinetic values generated at slow speeds (12°s-1, 30°s-1 and 60°s-1) based on measurement of 40 college males. A one-way ANOVA indicated a significant difference with respect to speeds. A post hoc analysis showed that all speeds were significantly different from each other. The greatest average maximal hamstring strength values were produced with isometric (O°s-1) contractions and the least average maximal hamstring strength at 60° s-1. It is suggested that if a true absolute maximal hamstring strength test is desired for the hamstring musculature one should use a speed of 0°s-1. Regression analysis indicated that a speed of 12°s-1 produced the best regression equation. It is suggested that, the term peak strength rather than maximum strength should be used for speeds greater than O°s-1 Langue : ANGLAIS Tiré à part : OUI Identifiant basis : 2001216005 |
