Reliabilita testování maximální volní kontrakce horních a dolních končetin a trupu na izometrickém dynamometru
The reliability of maximal voluntary contraction testing of upper and lower body limbs and trunk on isometric dynamometer

Summary/Abstract: The aim of this study was to assess the reliability of isometric strength measurement in flexion and extension in the chosen joints of upper and lower body extremities using the dynamometer Vishay Tedea-Huntleigh Model 1042. The measurements were undertaken in two days with the rest period of forty-eight hours between sessions. Twenty sport students took part in the study (6 females, 25 ± 2,3 years; 14 males, 24,4 ± 2,7 years). We used the intraclass correlation coefficient (ICC) model (3,k) and Pearson´s r to assess the reliability. ICC of elbow flexion and extension was 0,92–0,96 (r =0,62–0,93), knee flexion and extension 0,91–0,95 (r = 0,87–0,92), trunk abduction and flexion were 0,85 and 0,75.
