Athletes aim to improve muscle strength to optimize sports performance and gain a competitive edge. Although modern sports medicine includes rehabilitation treatment methods for improving the explosive force of athletes, including acupuncture, a common alternative therapy, research on the effectiveness of acupuncture in improving the timeliness of explosive forces is limited. There is uncertainty regarding how long the effects of acupuncture treatment persist after treatment. Therefore, the purpose of this study was to explore the effect of acupuncture on the timeliness of explosive forces generated by the male shoulder joint. Eighteen healthy men underwent tests of shoulder adduction/abduction (Add/Abd) and flexion/extension (Flex/Ext) through an isokinetic measurement system. Acupuncture was used to stimulate LU1 (), LU3 (), LU4 (), LI14 (), SJ13 (), SJ14 (), and SJ12 (), and the isokinetic parameters were recorded before and after acupuncture. After acupuncture, isokinetic muscle force parameters including the maximum (Max) torque, the average power, the average peak power, the average work, and the total work increased significantly ( < 0.05), whereas the average max torque Abd/Flex did not. Additionally, the preintervention values of the shoulder joints for Add/Abd and Flex/Ext were significantly greater than those at post 1 and post 2 ( < 0.05). The isokinetic results suggest that acupuncture can increase the explosive force of the male shoulder joint Add/Abd and Flex/Ext. Muscle cannot be fully activated when calcium saturation is below the maximal level. In this case, the postactivation potentiation (PAP) may enhance voluntary muscle force production. The effect of acupuncture is time-dependent, that is, the effects of acupuncture gradually weaken and disappear by approximately 10 minutes after acupuncture. Therefore, we suggest that acupuncture is used as an alternative therapy in sports competitions to increase the explosive forces of the shoulder joint, thereby improving sports performance.
运动员旨在增强肌肉力量以优化运动表现并获得竞争优势。尽管现代运动医学包括用于提高运动员爆发力的康复治疗方法，如针灸这种常见的替代疗法，但关于针灸在提高爆发力及时性方面的有效性研究有限。针灸治疗后效果能持续多长时间尚不确定。因此，本研究的目的是探讨针灸对男性肩关节产生爆发力及时性的影响。18名健康男性通过等速测量系统进行了肩关节内收/外展（Add/Abd）和屈伸（Flex/Ext）测试。采用针灸刺激肺经1穴（）、肺经3穴（）、肺经4穴（）、大肠经14穴（）、三焦经13穴（）、三焦经14穴（）和三焦经12穴（），并记录针灸前后的等速参数。针灸后，包括最大（Max）扭矩、平均功率、平均峰值功率、平均功和总功在内的等速肌肉力量参数显著增加（<0.05），而平均最大扭矩Abd/Flex未增加。此外，Add/Abd和Flex/Ext肩关节的干预前值显著高于干预后1和干预后2时的值（<0.05）。等速测试结果表明，针灸可增加男性肩关节Add/Abd和Flex/Ext的爆发力。当钙饱和度低于最大水平时，肌肉无法被充分激活。在这种情况下，激活后增强效应（PAP）可能会增强自主肌肉力量的产生。针灸的效果具有时间依赖性，即针灸后约10分钟，其效果逐渐减弱并消失。因此，我们建议在体育比赛中使用针灸作为替代疗法来增加肩关节的爆发力，从而提高运动表现。
