Leg Prosthesis Stiffness and Take-off Board Stiffness Affect Long Jump Performance: Statistics, figures, and corresponding data

R-markdown files of statistical analysis of collected data and reported results (LongJump_Stats). R-markdown file of graphs used to display results (LJgraphing) and .csv file of collected data (LongJumpData.csv).We determined run-up velocity and jump distance of athletes with TTA who used an RSP with a manufacturer-recommended stiffness category (Rec Cat; 39.5 kN/m), one category less (-1 Cat; 36.0 kN/m) and more stiff (+1 Cat; 43.9 kN/m) and non-amputee athletes who used a regulation run-up surface with a regulation take-off platform (1630 kN/m), and two compliant take-off platforms (84.0 and 90.0 kN/m). We measured maximum run-up velocity (m/s) using a radar gun, take-off platform displacement (m) using high-speed camera and kinovea, and compared these between stiffnesses, and across subjects.

本数据集包含三类文件：一是用于对采集数据与报告结果开展统计分析的R Markdown文件（LongJump_Stats）；二是用于生成结果展示图表的R Markdown文件（LJgraphing）；三是存储采集所得原始数据的CSV文件（LongJumpData.csv）。本研究针对两类受试者展开测试：第一类为经胫骨截肢（Trans-tibial Amputation, TTA）运动员，其使用的刚性短跑假肢（Rigid Sprinting Prosthesis, RSP）分别采用制造商推荐刚度等级（Rec Cat；39.5 kN/m）、低一个刚度等级（-1 Cat；36.0 kN/m）与高一个刚度等级（+1 Cat；43.9 kN/m）；第二类为非截肢运动员，其分别使用合规助跑跑道与合规起跳平台（1630 kN/m），以及两种柔性起跳平台（刚度分别为84.0 kN/m与90.0 kN/m）。本研究测定了所有受试者的助跑速度与跳远距离，其中最大助跑速度（单位：m/s）通过雷达枪测量，起跳平台位移（单位：m）通过高速摄像机与Kinovea软件测量，并对不同刚度组别间以及不同受试者间的测量结果开展对比分析。
