Issues with using the exercise monitoring system were
described narratively while the association between self-reported
adherence and data from the exercise monitoring system were
described using an unpaired t-test and the Pearson correlation
coefficient. Changes in isometric strength and knee pain before and
after each exercise set were tested using a paired-samples t-test.
An exploratory analysis was performed to test the association
between total time under tension and the average composite
change in hip and knee strength. This was tested using a Pearson
correlation coefficient. Normality was checked with Q-Q plot
