Abstract

The purpose of this research was to compare isometric values (0°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 (F 3,148 = 13.10, p < 0.01) 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 (0°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 0°s -1 .
