Peak vertical tibial accelerations during running have shown strong correlations with vertical ground reaction force loading rates and some associations with injury. However, little attention has been given to tibial accelerations along the medial–lateral and anterior-posterior axes. Therefore, our purpose was to examine the correlation between peak tibial accelerations and ground reaction force loading rates in the medial–lateral and posterior directions. Eighteen recreational runners were recruited who ran with a rearfoot strike pattern (10 men/ 8 women, mean age (yrs) = 33 ± 11). Tibial accelerations and ground reaction forces were collected while participants ran on an instrumented treadmill at a self-selected speed. Correlations were developed for: a) peak medial and lateral accelerations with lateral and medial loading rates, respectively, b) peak anterior tibial accelerations and posterior loading rates. Significant correlations were found between tibial accelerations and loading rates in all planes. Peak medial tibial accelerations were correlated with lateral loading rates (R_s = 0.86, p < 0.001) and peak lateral tibial accelerations were correlated with peak medial loading rates (R_s = 0.91, p < 0.001). A lower correlation was found between anterior accelerations and posterior loading rates (R_s = 0.51, p = 0.030). Tibial accelerations in the medial–lateral plane seem to be a valid surrogate for the respective ground reaction force measures during running on a treadmill, explaining 74–83% of the variance in loading rates. However, with only 26% of the variance explained, the same may not be true for anterior tibial accelerations and posterior loading rates.

跑步过程中最高的垂直胫骨加速度已经显示出与地面垂直反作用力加载速率的强烈相关性，以及与伤害的某些相关性。然而，很少有人关注沿内侧，外侧和前后轴的胫骨加速度。因此，我们的目的是检查胫骨峰值加速度与内侧，外侧和后部方向的地面反作用力加载速率之间的相关性。招募了18名以后脚罢工模式跑步的休闲跑步者（10名男性/ 8名女性，平均年龄（年）= 33±11）。参与者在自行选择的跑步机上跑步时，收集了胫骨加速度和地面反作用力。建立了以下相关性：a）峰值内侧和外侧加速度分别具有外侧和内侧载荷率，b）胫骨前加速度峰值和后负荷率。在所有平面中，胫骨加速度与负重率之间均存在显着相关性。胫骨内侧加速度峰值与外侧负荷率相关（R_s  = 0.86，p <0.001），峰值胫骨外侧加速度与峰值内侧负荷率相关（R _s  = 0.91，p <0.001）。发现前向加速度和后向负荷率之间的相关性较低（R _s  = 0.51，p = 0.030）。在跑步机上跑步时，内侧-外侧平面中的胫骨加速度似乎是相应的地面反作用力度量的有效替代，从而解释了74％至83％的负荷率变化。但是，仅解释了26％的方差，对于胫骨前加速和后负荷率可能并非如此。
