The Biomechanics Effect of Hamstring Flexibility on the Risk of Osgood-Schlatter Disease

Figure 4

Force (A) and SPM{t} (B) curves. The force is described as mean (hard line) ± standard deviation (shaded area). The shaded areas on the SPM{t} curve show the track locations where the SPM{t} curve exceeded the critical threshold (dotted line). values are provided for these suprathreshold clusters. (a) Optimal lengths reduced by 20%. (b) Optimal lengths reduced by 25%. (c) Optimal lengths reduced by 30%.
