The Contribution Ratio of Some Body Lengths to the Accuracy of the Volleyball Spike Among Third-Year Female Students at the College of Physical Education and Sports Sciences at the University of Kufa

The spike represents one of the most important offensive techniques in volleyball, as its successful execution depends on a set of specific physical characteristics and performance capabilities that enable players to apply it effectively during competition. In practice, coaches often prefer players who specialize in spiking and meet the height requirements that support efficient performance in this role. Accordingly, this aspect forms the core problem examined in the present study. In light of this, the study primarily aims to identify the body height variables associated with spike performance among the target population and to determine the relative contribution of each anthropometric variable to performance outcomes. To address these aims, the researcher adopted a descriptive research design using both survey and correlational approaches. The study sample consisted of female students enrolled in the College of Physical Education and Sports Sciences at the University of Kufa during the academic year (2024–2025). A range of data collection instruments and procedures was applied throughout the research process. Following a sequence of field-based procedures including determining the body measurements most closely linked to spike execution, establishing the validity of the spike test, conducting the primary experiment, and applying appropriate statistical analyses the findings indicated that spike performance is significantly associated with several anthropometric measurements, particularly forearm length and hand length. Moreover, increases in these measurements were found to correspond with greater spike accuracy among female students at the College of Physical Education and Sports Sciences, University of Kufa.
