A Comparison of Hip Extension and Nordic Hamstring Exercise Programmes on Isokinetic Hamstring Strength

Recruitment: Participants were recruited from the local university sports clubs. Club chairpersons were asked to send an email to club players. Players interested in participating in the study expressed an interest by replying to the email. Potential participants were asked to attend a meeting where they had the study explained to them. Those who were interested were then assessed for inclusion and exclusion criteria. Group allocation: A four block randomisation method was used to allocate participants to the Nordic hamstring exercise protocol or the hip extension exercise protocol. Interventions: The Nordic hamstring exercise protocol or the hip extension exercise protocol Testing procedure: The isokinetic strength of the participants' hamstrings and quadriceps were recorded before and after the exercise intervention. A 10 point visual analogue scale was used to record the level of muscle soreness experienced after each training session.
