Passive plantar-flexor flexibility relating to ankle mechanics during drop landings.

The dataset is generated in relation to human movement of the ankle. It contains three-dimensional kinematic data of the lower limb during single limb drop landing tasks from different take off heights ( 32 cm. and 72 cm.) and surface electromyographic activity of four lower limb muscles (tibialis anterior, soleus, medial gastrocnemius, and lateral gastrocnemius) during the landing tasks, as well as ground force data generated during the landing tasks. The landing technique of forty eight consenting males were analysed for approximately two hours per participant in the Biomechanics Research Laboratory at the University of Wollongong to collect the data. The data was collected by PhD candidate, John Whitting, who was assisted by a team of trained research assistants, using an OptoTRAK 3020 motion analysis system to collect the kinematic data, two Kistler force platforms to collect the ground reaction force data and a Noraxon Telemyo 900 EMG system to collect the muscle activity data.

本数据集围绕人类踝关节运动开展构建，涵盖三类核心实验数据：其一为不同起跳高度（32cm与72cm）下单腿下落落地任务中下肢的三维运动学数据；其二为落地过程中四块下肢肌肉（胫骨前肌(tibialis anterior)、比目鱼肌(soleus)、腓肠肌内侧头(medial gastrocnemius)、腓肠肌外侧头(lateral gastrocnemius)）的表面肌电活动数据；其三为落地阶段产生的地面反作用力数据。数据采集工作在伍伦贡大学（University of Wollongong）生物力学研究实验室（Biomechanics Research Laboratory）完成，共招募48名签署知情同意书的男性受试者，对每位受试者的落地技术动作开展约2小时的分析以完成数据采集。本次数据集由博士生约翰·惠廷（John Whitting）主导采集，由一支经过专业培训的研究辅助团队协助完成；实验中采用OptoTRAK 3020运动分析系统采集运动学数据，搭配两台Kistler测力台采集地面反作用力数据，并通过Noraxon Telemyo 900肌电系统采集肌肉活动数据。
