With rapid technological development over recent years, the use of wearable athlete monitoring devices has substantially gained popularity. Thus, the purpose of the present study was to examine the impact of the anatomical placement of an accelerometer on biomechanical characteristics of countermovement vertical jump with and without an arm swing when compared to the force plate as a criterion measure. Seventeen recreationally active individuals (ten males and seven females) volunteered to participate in the present study. Four identical accelerometers sampling at 100 Hz were placed at the following anatomical locations: upper-back (UB), chest (CH), abdomen (AB), and hip (HP). While standing on a uni-axial force plate system sampling at 1000 Hz, each participant completed three non-sequential maximal countermovement vertical jumps with and without an arm swing. All devices recorded the data simultaneously. The following variables of interest were obtained from ground reaction force curves: peak concentric force (PCF), peak landing force (PLF), and vertical jump height (VJH). The findings of the present study reveal that the most appropriate anatomical locations to place the accelerometer device when attempting to estimate PCF, PLF, and VJH during a countermovement vertical jump with no arm swing are CH, AB, and UB, and during a countermovement vertical jump with an arm swing are UB, HP, and UB, respectively. Overall, these findings may help strength and conditioning professionals and sports scientists to select appropriate anatomical locations when using innovative accelerometer technology to monitor vertical jump performance characteristics.
近年来，随着技术的快速发展，可穿戴式运动员监测设备的使用已大幅普及。因此，本研究的目的是，将加速度计放置在不同解剖位置时，对比作为标准测量设备的测力台，研究其对有无摆臂的反向纵跳生物力学特征的影响。17名经常运动的个体（10名男性和7名女性）自愿参与本研究。四个相同的加速度计以100Hz的采样频率放置在以下解剖位置：上背部（UB）、胸部（CH）、腹部（AB）和髋部（HP）。每位参与者站在一个以1000Hz采样频率的单轴测力台系统上，完成三次不连续的最大反向纵跳，分别有无摆臂动作。所有设备同时记录数据。从地面反作用力曲线中获取以下感兴趣的变量：向心峰值力（PCF）、着陆峰值力（PLF）和垂直跳高度（VJH）。本研究结果表明，在无摆臂的反向纵跳中，试图估算PCF、PLF和VJH时，放置加速度计设备的最合适解剖位置分别是CH、AB和UB；在有摆臂的反向纵跳中，最合适的解剖位置分别是UB、HP和UB。总体而言，这些发现可能有助于体能训练专业人员和运动科学家在使用创新型加速度计技术监测纵跳性能特征时选择合适的解剖位置。
