An intra-subject experimental design was used to evaluate the possible acute effect of KT using the X-
shaped taping technique on hamstring muscle extensibility in university students. All measurements were carried
out during the same testing session, administered one day, at the same time (from 10 to 15 pm) at the Human
Movement Laboratory of the University of Malaga College of Education. Students were examined without shoes
and were only wearing their underwear. No warm-up or stretching exercises were performed by the participants
prior to the test measurements.
