Changes in force applied to the patellar tendon (A), tendon stiffness (B) and strain (C) in a sub-group of the asymptomatic (n = 13) and symptomatic group (n = 8) from the preceding session to the last measurement session prior to symptom development in the affected athletes. Data points are shown as outliers if the distance to the 1st or 3rd quartile exceeded 1.5 times the interquartile range. The p values for independent sample testing as well as Cohen’s d are given as well.
