This study examined the effect of the handball warm-up program (HWP) on dynamic balance among elite adolescent handball players. In this case, 24 handball players were randomly assigned into experimental warm-up and control groups. The HWP was performed over 8 weeks (3 times per week). Dynamic balance before and after the intervention training programs were measured by the Biodex Balance System (BBS) and Y Balance test for the dominant (DL) and non-dominant legs (non-DL). After HWP training, BBS scores significantly improved in the overall (OSI) (30.4% and 31.1%), anterior-posterior (APSI) (44.6% and 35.2%), and medial-lateral stability indexes (MLSI) (38.8% and 43%) for both DL and non-DL. Post-training, the Y Balance test exhibited significant improvements in OSI (13.2% and 10.6%), anterior (17.2% and 12.6%), posteriolateral (12.8% and 11.3%), and posteriomedial stability indexes (9.2% and 7.9%) with DL and non-DL, respectively. In conclusion, dynamic balance improved overall after eight weeks of the HWP, with this improvement significantly greater with the trained versus the control group. Optimal balance during handball is an important factor to ensure coordinated and efficient movements and it is speculated that improved balance could positively impact injury prevention. Hence, the HWP program can be used as an alternative to a conventional warm-up program.
本研究考察了手球热身计划（HWP）对精英青少年手球运动员动态平衡的影响。在本研究中，24名手球运动员被随机分为实验热身组和对照组。HWP持续进行8周（每周3次）。干预训练计划前后的动态平衡通过Biodex平衡系统（BBS）以及优势腿（DL）和非优势腿（非DL）的Y平衡测试进行测量。经过HWP训练后，优势腿和非优势腿的BBS总分（OSI）（分别提高30.4%和31.1%）、前后稳定性指数（APSI）（分别提高44.6%和35.2%）以及内外侧稳定性指数（MLSI）（分别提高38.8%和43%）均有显著改善。训练后，Y平衡测试显示优势腿和非优势腿的OSI（分别提高13.2%和10.6%）、前侧（分别提高17.2%和12.6%）、后外侧（分别提高12.8%和11.3%）以及后内侧稳定性指数（分别提高9.2%和7.9%）均有显著提高。总之，经过8周的HWP训练后，动态平衡总体上有所改善，训练组的改善程度明显大于对照组。手球运动中的最佳平衡是确保动作协调高效的重要因素，据推测，平衡能力的提高可能对预防损伤产生积极影响。因此，HWP计划可作为传统热身计划的替代方案。
