Related Data for: Playing basketball on wooden and asphalt courts – Does court surface affect foot loading?

This study aimed to examine the influence of court surface on foot loading when executing typical basketball tasks. Thirteen male basketball players performed three basketball-related tasks: Layup, jump shot, and maximal effort sprint on wooden and asphalt courts. In-shoe plantar loading was recorded during the basketball movements and peak force (normalised to body weight) was extracted from eight-foot regions. Perceptions of discomfort at the ankle, knee, and back were surveyed using a 10-cm visual analogue scale. Landing from a layup on the wooden court resulted in elevated peak forces at the hallux (p = 0.022) and lesser toes (p = 0.007) compared with asphalt court. During the sprint acceleration step, higher peak forces were observed at the hallux (p = 0.048) and medial forefoot (p = 0.010) on wooden court. No difference between court surfaces was found for perception ratings at the ankle, knee, or back. These results suggested that players can experience greater impact forces at the toes and medial forefoot when performing basketball tasks on the more compliant wooden court than asphalt courts.

本研究旨在探究篮球典型动作执行过程中，场地表面对足部载荷的影响。13名男性篮球运动员完成三项篮球相关任务：上篮、跳投及全力冲刺，测试场地涵盖木质场地与沥青场地。运动期间记录鞋内足底载荷，并从足部八个区域提取标准化至体重的峰值力。采用10厘米视觉模拟量表（Visual Analogue Scale）对受试者踝关节、膝关节及背部的不适感进行调查。相较于沥青场地，在木质场地上篮落地时，拇趾（p = 0.022）与其余足趾（p = 0.007）的峰值力显著升高；冲刺加速步阶段，木质场地中拇趾（p = 0.048）与足内侧前掌（p = 0.010）的峰值力更高。两种场地在踝关节、膝关节及背部的不适感评分上均无显著差异。上述结果表明，相较于沥青场地，运动员在弹性更强的木质场地上完成篮球动作时，足趾与足内侧前掌区域将承受更大的冲击力。
