This study aimed to explore the differences in the distributions of plantar pressure in static and dynamic states and assess the possible pain profiles in the lower limb between elite rugby league athletes and recreational rugby players.
A cross-sectional study of 51 college elite rugby athletes and 57 recreational rugby players was undertaken. The arch index (AI) and plantar pressure distributions (PPDs) with footprint characteristics were evaluated via the JC Mat. Rearfoot alignment was examined to evaluate the static foot posture. The elite group's lower-limb pain profiles were examined for evaluating the common musculoskeletal pain areas.
The recreational group's AI values fell into the normal range, whereas the elite group's arch type fell into the category of the low arch. Results from the elite group were: (1) the PPDs mainly exerted on the entire forefoot and lateral midfoot regions in static standing, and transferred to the forefoot region during the midstance phase of walking; (2) the static rearfoot alignment matched the varus posture pattern; (3) the footprint characteristics illustrated the features of low-arched, supinated, dropped metatarsal heads and dropped cuboid feet; and (4) the phalanx and metatarsophalangeal joints, and the abductor hallucis and abductor digiti minimi of the plantar plate were common musculoskeletal pain areas.
Characteristics of higher plantar loads beneath forefoot and midfoot associated with low-arched supinated feet in bipedal static stance could be the traceable features for the foot diagram of elite rugby league athletes. The limb pain profiles of the elite rugby league athletes within this study echoed the literature on rugby injuries, and reflected the features of metatarsophalangeal joint pains and dropped cuboids. The relationships among the low-arched supinated feet, metatarsophalangeal joint pains and cuboid syndrome are worth further studies.
本研究旨在探讨精英英式橄榄球运动员与休闲英式橄榄球运动员在静态和动态状态下足底压力分布的差异，并评估下肢可能的疼痛特征。
采用横断面研究方法，对 51 名大学生精英英式橄榄球运动员和 57 名休闲英式橄榄球运动员进行研究。采用 JC Mat 评估足弓指数（AI）和足底压力分布（PPD）及足印特征。通过后足对线评估静态足姿势，以评估后足对线。检查精英组的下肢疼痛特征，以评估常见的肌肉骨骼疼痛区域。
休闲组的 AI 值处于正常范围，而精英组的足弓类型属于低弓。精英组的结果如下：（1）静态站立时，足底压力主要分布在整个前足和外侧中足区域，在步行的中间阶段转移到前足区域；（2）静态后足对线符合内翻姿势模式；（3）足印特征显示出低弓、旋前、跖骨头下降和骰骨下降的特征；（4）跖趾关节和趾间关节、足底外侧展肌和足底外侧小趾展肌是常见的肌肉骨骼疼痛区域。
双足静态站立时前足和中足承受较高的足底压力，伴有低弓旋前足，这可能是精英英式橄榄球运动员足部图谱的可追踪特征。本研究中精英英式橄榄球运动员的肢体疼痛特征与橄榄球损伤文献相呼应，反映了趾间关节疼痛和骰骨下降的特征。低弓旋前足、趾间关节疼痛和骰骨综合征之间的关系值得进一步研究。
