Background Warm-ups optimize athletic performance; however, excessively active warm-ups may induce fatigue. Passive warm-up strategies, including thermotherapy, offer physiological benefits, although their immediate performance effects are unclear. High-voltage pulsed-current (HVPC) electrical stimulation, used in rehabilitation to activate deep muscles, has not been fully explored as a warm-up strategy. This study examined the immediate effects of short-duration HVPC stimulation combined with abdominal hollowing exercises on jump performance. Methods A total of 36 healthy participants were randomly assigned to the HVPC (n = 18) or control (n = 18) group. The HVPC group performed abdominal hollowing exercises with HVPC stimulation for 4 minutes, while the control group performed the exercises without electrical stimulation. The rebound jump (RJ) index, jump height, and ground contact time were measured before and after the intervention. A paired t-test was used to compare the pre- and post-experiment measurements. Results The HVPC group showed a significant increase in jump height (pre 31.95 ± 6.42 vs post 33.64 ± 6.61) ( < 0.05) and RJ index (pre 1.67 ± 0.47 vs post 1.75 ± 0.44) ( < 0.05) post-intervention, whereas the ground contact time remained unchanged. The control group showed no significant changes in any parameter. Conclusion Short-duration HVPC stimulation combined with abdominal hollowing exercises improved jump performance. HVPC-assisted warm-ups show potential, particularly in sports.
背景 热身运动可优化运动表现；然而，过度活跃的热身运动可能会导致疲劳。被动热身策略，包括热疗法，具有生理益处，尽管其对运动表现的即时影响尚不清楚。高压脉冲电流（HVPC）电刺激在康复中用于激活深层肌肉，但作为一种热身策略尚未得到充分探索。本研究探讨了短时间HVPC刺激结合收腹练习对跳跃表现的即时影响。方法 总共36名健康参与者被随机分为HVPC组（n = 18）或对照组（n = 18）。HVPC组在HVPC刺激下进行收腹练习4分钟，而对照组在无电刺激的情况下进行该练习。在干预前后测量反弹跳（RJ）指数、跳跃高度和地面接触时间。采用配对t检验比较实验前后的测量结果。结果 HVPC组干预后跳跃高度（干预前31.95±6.42 vs 干预后33.64±6.61）（<0.05）和RJ指数（干预前1.67±0.47 vs 干预后1.75±0.44）（<0.05）显著增加，而地面接触时间保持不变。对照组在任何参数上均无显著变化。结论 短时间HVPC刺激结合收腹练习可改善跳跃表现。HVPC辅助热身运动显示出潜力，尤其是在运动方面。
