Isokinetic strength of shoulder rotation in elite Czech female volleyball players
 Hoppeová, Andrea ; Šteffl, Michal (advisor) ; Vorálek, Rostislav (referee)
Title: Isokinetic strength of shoulder rotation in elite Czech female volleyball players Objectives: The main goal was to evaluate and compare the results of measuring internal and external rotation in the shoulder joint of elite volleyball players of the age categories "Women" and "Juniors U18". Method: The players of the national teams "Juniors U18" and "Women" took part in the measurement. Isokinetic strength parameters were measured using a Cybex Humac Norm isokinetic dynamometer (Cybex NORM®, Humac, CA, USA). The maximum strength of internal and external rotation of the shoulder joint was evaluated. Muscle strength was measured at an angular velocity of 60 ř/s and the upper limb was abducted at 90ř. Descriptive statistics on the test result were calculated and evaluated using the Excel software (Microsoft, USA). Statistical data processing was performed at the level of comparison of averages and percentage differences between individual categories of results. Results: The results show that the Women group had higher strength than the U18 Junior group. On the contrary, the U18 Junior group had more balanced results, both between the dominant and non-dominant limb and between internal and external rotation. The measured strength of rotation in Women shown a greater muscle imbalance. In...
