Abstract

This study aimed to compare lower-limb peak isometric force characteristics in water polo players using the Takei back and leg dynamometer. Two testing positions were employed: full knee extension and 90-degree knee flexion. A total of 38 athletes were assessed, divided into U16 and U18 age groups. While no statistically significant differences were found between age groups, highly significant intra-group differences emerged between test positions (p < .001), with substantially greater force values recorded in full extension. These results underline the influence of joint angle on isometric strength outcomes and highlight the importance of standardizing test positions in strength assessment protocols for water polo players.
