The utilization of isokinetic dynamometer for the measurement and evaluation of muscle strength of lower limbs in athletes
 Přidalová, Tereza ; Janoušek, Oto (oponent) ; Chlíbková, Daniela (vedoucí práce)
Isokinetic dynamometry is the up-to-date method for evaluation of muscle strength. It is mostly used to estimate the effect of training over time and for rehabilitation purposes. Clinicians, researchers and physiotherapists usually employ only the basic parameters obtained by the dynamometry to assess the muscle strength. Therefore, this work aims to propose an alternative approach for data interpretation, together with revealing possible applications and limitations of this method. The torque of the knee joint and subsequent analysis was performed. Fifteen parameters are used for data evaluation. The peak torque values of professional athletes (men: 111.1 ± 51.0 [Nm/kg], women: 99.6±90.8 [Nm/kg]) were compared against amateur athletes (men: 146.2±40.1 [Nm/kg], women: 45.3±14.6 [Nm/kg]). The relation was observed among parameters of the peak angle and time from peak torque to the end of motion (flexion: = 0.65, extension: = 0.71) and between the peak angle and ratio work produced before maximum (flexion: = 0.91 extension: = 0.86). The parameter of work performed in the submaximal area was higher for extension (median= 3.0 J) than for flexion (median= 2.6 J).
