The addition of highly responsive lightweight foam and a stiff plate in the midsole of long-distance road racing shoes has yielded significant energetic cost savings that have translated to notable improvements in performance. This new foam and stiff plate technology have since been implemented in long-distance track spikes, where performances have also improved. However, the impact of spikes with advanced footwear technology (AFT) on distance running biomechanics has been studied minimally to date. Therefore, the purpose of this study was to compare running biomechanics between two spikes which incorporate AFT (Nike ZoomX Dragonfly, Nike Air Zoom Victory) to a traditional spike (Nike Zoom Matumbo). Seventeen competitive collegiate female runners completed 60 m trials at their 5k race pace in each spike condition while outfitted with IMU sensors and plantar pressure insoles. We observed significantly lower peak ankle dorsiflexion in the Dragonfly and Victory compared to the Matumbo and lower whole foot, forefoot and rearfoot peak and average pressure in the Dragonfly compared to the Matumbo and Victory. The acute biomechanical alterations observed in this study warrant future investigation into the association between running biomechanics and racing performance in track spikes with advanced footwear technology.
在长跑跑鞋的中底添加高响应性轻质泡沫和刚性板，已显著节省了能量消耗，并转化为性能上的显著提升。此后，这种新的泡沫和刚性板技术已应用于长跑钉鞋，其性能也有所提高。然而，迄今为止，对采用先进鞋类技术（AFT）的钉鞋对长跑生物力学的影响研究甚少。因此，本研究的目的是比较两种采用AFT的钉鞋（耐克ZoomX蜻蜓钉鞋、耐克气垫Zoom胜利钉鞋）与传统钉鞋（耐克Zoom马通博钉鞋）之间的跑步生物力学。17名有竞争力的大学女子跑步运动员在每种钉鞋条件下，以5公里比赛配速完成60米的测试，同时配备惯性测量单元（IMU）传感器和足底压力鞋垫。我们观察到，与马通博钉鞋相比，蜻蜓钉鞋和胜利钉鞋的踝关节背屈峰值显著更低；与马通博钉鞋和胜利钉鞋相比，蜻蜓钉鞋的全足、前足和后足峰值及平均压力更低。本研究中观察到的急性生物力学改变，值得未来对采用先进鞋类技术的钉鞋的跑步生物力学与比赛成绩之间的关联进行研究。
