Increased tibial axial acceleration and reduced shock attenuation are associated with running injuries and are believed to be influenced by surface type. Trail running has increased in popularity and is thought to have softer surface properties than paved surface, but it is unclear if trail surfaces influence tibial acceleration and shock attenuation. The purpose of this study was to investigate peak triaxial and resultant tibial acceleration as well as axial and resultant shock attenuation among dirt, gravel, and paved surfaces.
Fifteen recreational runners (12 females, 3 males, age=27.7±9.1 years) ran over dirt, gravel, and paved surfaces in a trail environment while instrumented with triaxial tibial and head accelerometers.
Differences between tri-planar peak tibial accelerations (braking, propulsion, axial, medial, lateral, and resultant) and shock attenuations (axial and resultant) among surface types were assessed with one-way ANOVAs with Bonferroni post-hoc tests.
No significant differences were found for tibial accelerations or shock attenuations among surface types (p>0.05).
Dirt and gravel trail running surfaces do not have lower tibial accelerations or greater shock attenuation than paved surfaces. While runners are encouraged to enjoy the psychological benefits of trail running, trail surfaces do not appear to reduce loading forces associated with running-related injuries.
胫骨轴向加速度增加和冲击衰减减少与跑步损伤有关，据信这与地面类型有关。越野跑越来越受欢迎，被认为具有比铺砌表面更柔软的表面特性，但尚不清楚越野表面是否会影响胫骨加速度和冲击衰减。本研究的目的是调查在土路、砾石路和铺砌路面上的三轴和胫骨峰值加速度以及轴向和总冲击衰减。
15 名休闲跑步者（12 名女性，3 名男性，年龄=27.7±9.1 岁）在越野环境中使用三轴胫骨和头部加速度计在土路、砾石路和铺砌路面上跑步。
使用单向方差分析和 Bonferroni 事后检验评估不同表面类型之间的三平面峰值胫骨加速度（制动、推进、轴向、内侧、外侧和总）和冲击衰减（轴向和总）之间的差异。
在胫骨加速度或冲击衰减方面，不同表面类型之间没有显著差异（p>0.05）。
土路和砾石越野跑表面的胫骨加速度或冲击衰减并不低于铺砌表面。虽然鼓励跑步者享受越野跑的心理益处，但越野表面似乎不会减少与跑步相关损伤相关的加载力。
