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.
