The aim of this study was to develop a reproducible, valid, and feasible test to assist in objectively selecting talented youth volleyball players based on serving and spiking skills, which are important technical skills. Furthermore, the relationship between ball speed in throwing and hitting was analyzed. Ball speed was measured in throwing and hitting in service and spike tests with a radar gun. Elite (regional training center (RTC); n=20; age: 13.27 ±.55) and sub-elite (highest U14 competition level, but not selected for an RTC; n=18; age: 13.49 ±.59) female youth volleyball players performed the tests on a regular volleyball court. Test and retest were conducted with elite players with one week in between. Reproducibility was assessed with paired t-tests, ICC, SEM, and SDC between test and retest. Validity between elite and sub-elite players was examined with independent t-tests. Test scores of elite players were also compared with current performance and potential playing level, evaluated by coaches, by means of regression analyses. Feasibility was evaluated by the researchers. The correlation between throwing and hitting was assessed with Pearson correlations. All ICC coefficients were good to excellent values (ICC>.60; p>.05), indicating the test is reproducible. The scores of elite and sub-elite players did not differ significantly. Regular service tests predicted performance and potential. All service and spike tests showed significant correlation between throwing and hitting (.493<r<.594; p<.05 or p<.01). All subtests of the volleyball service and spike test (VSST) showed satisfactory reproducibility and feasibility. The regular service test was also valid. Also, a moderate correlation between throwing and hitting in volleyball players was found. It can be concluded that the VSST can assist in monitoring and selecting talented female U14 volleyball players. KEY WORDS: Reproducibility, validity, feasibility, throw, female
