- BMI outside 18-25, since excessive adipose tissue around the hip region will
make it difficult to get clear images of the hamstrings tendon tissue;
- Known cardiovascular or other diseases;
- In accordance with a previous study13, hypoechoic areas on the tomographic
planes in the 3-D volume of the UTC measurements did not lead to exclusion.For
control participants, the following additional exclusion criteria apply:-
