The aim of this study was to investigate the response to non-tackle and tackle field-based training on upper- and lower-limb neuromuscular function in elite rugby union players. Nine elite senior elite rugby union players (mean age = 21 ± 2 years; height = 184 ± 7 cm; body mass 91.0 ± 9 kg) were evaluated before and immediately following 17 training sessions. A total of 306 assessments were performed. Data on neuromuscular function of plyometric push-up and countermovement jump were calculated from force signals using inverse dynamics. The change from pre- to post-session was investigated across non-tackle and tackle training using a linear mixed model. Considering upper-limb neuromuscular function, peak concentric power [P = 0.024; ES = 0.33 95%CI (0.04, 0.62)] was significantly lower after tackle compared to non-tackle training. In addition, peak countermovement jump eccentric power was significantly lower after non-tackle compared to tackle training [P = 0.044; ES = -0.4 95%CI (-0.69, -0.1)] in lower-limb neuromuscular function. Overall, the results indicated that the type of training influences upper- and lower-limb neuromuscular function differently immediately after training. Indeed, due to physical contact, the upper-body neuromuscular function increased during tackle training. In contrast, lower-body neuromuscular function emerged only in non-tackle training, due to the greater distance covered during this type of training session. Coaches and practitioners should plan adequate weekly training sessions according to this information.
本研究的目的是调查精英橄榄球联盟球员对上、下肢神经肌肉功能的非擒抱和擒抱实地训练的反应。九名精英成年精英橄榄球联盟球员（平均年龄 = 21 ± 2岁；身高 = 184 ± 7厘米；体重91.0 ± 9千克）在17次训练前后进行了评估。总共进行了306次评估。使用逆动力学从力信号计算纵跳俯卧撑和反向移动跳的神经肌肉功能数据。使用线性混合模型研究了非擒抱和擒抱训练前后的变化。考虑上肢神经肌肉功能，与非擒抱训练相比，擒抱训练后峰值向心功率[P = 0.024；ES = 0.33 95%CI（0.04，0.62）]显著降低。此外，在下肢神经肌肉功能方面，与擒抱训练相比，非擒抱训练后反向移动跳的峰值离心功率显著降低[P = 0.044；ES = -0.4 95%CI（-0.69，-0.1）]。总体而言，结果表明训练类型在训练后立即对上、下肢神经肌肉功能产生不同影响。事实上，由于身体接触，擒抱训练期间上身神经肌肉功能增强。相比之下，由于这种训练类型中覆盖的距离更大，下身神经肌肉功能仅在非擒抱训练中出现。教练和从业者应根据此信息安排足够的每周训练课程。
