Figure 5.
Half angle swept (θ) and landing velocity (vland) across speed. (a,b) All subjects increased θ at faster speeds. The increase in θ was not as substantial in non-amputees (bioL) compared with all other conditions across speed. (c,d) vland decreased across velocity for all conditions. The linear fit equations for θ were bioL: θ = 1.21x + 18.53, R2 = 0.639, p < 0.001; UL: θ = 1.75x + 17.75, R2 = 0.642, p < 0.001; AL: θ = 1.93x + 15.51, R2 = 0.777, p < 0.001; BL: θ = 1.98x + 15.92, R2 = 0.752, p < 0.001. The linear fit equations for vland were bioL: vland = −0.021x + 0.779, R2 = 0.359, p < 0.001; UL: vland = −0.025x + 0.759, R2 = 0.333, p = 0.154; AL: vland = −0.007x + 0.680, R2 = 0.043, p < 0.001; BL: vland = −0.024x + 0.649, R2 = 0.651, p < 0.001. (a,c) Crosses with dashed line, bioL; filled circles with continuous line, UL. (b,d) open circles with solid line, AL; crosses with solid line, BL. (Online version in colour.)
