摘要：The aim of this study was to determine whether modification of the Step-hop test for assessing specificagility in volleyball would significantly shorten the performance time and improve homogeneity, i.e., reducethe differences between certain test items. The subject sample included 53 Croatian female volleyball playerswhose mean chronological age was 14.09±0.83 years, mean body height was 173.66±6.07 cm, and meanbody mass was 61.12±9.40 kg. It was determined that the Modified Step-hop test had better reliability(CA=0.96 and CV=0.10) as compared to the Step-hop test (CA=0.93; CV=0.37). By simplifyingperformance, homogeneity of the test was improved (Step-hop F-test = 40.78; Modified Step-hop F-test =10.76), and mean test performance time was shortened (Step-hop Mean = 10.75 sec; Modified Step-hopMean = 9.78 sec). Even though correlation between the applied tests was significant (r=0.71), 50% ofcommon explained variance points to somewhat different manifestations of agility required for performanceof these tests. It can be assumed that the Step-hop test, due to unusual way of movement direction change,could also be applied to assess specific coordination, whereas the Modified Step-hop test has better metriccharacteristics for assessing specific agility in young female volleyball players.
