The purpose of this research was to compare isometric values(0
$^{\circ}$
s
$^{-1}$
) with isokinetic values generated at slow speeds(12
$^{\circ}$
s
$^{-1}$
, 30
$^{\circ}$
s
$^{-1}$
and 60
$^{\circ}$
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
$^{\circ}$
s
$^{-1}$
) contractions and the least average maximal hamstring strength at 60
$^{\circ}$
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
$^{\circ}$
s
$^{-1}$
. Regression analysis indicated that a speed of 12
$^{\circ}$
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
$^{\circ}$
s
$^{-1}$
.
