The impact of physical effort on trapezius muscle stiffness among young swimmers
Journal Title: Medycyna Sportowa - Year 2017, Vol 33, Issue 3
Abstract
Background. With this study we wanted to evaluate the influence of physical effort during swimming on upper trapezius muscle stiffness. To the best of our knowledge no study has addressed efficacy of swimming on muscle stiffness, assessed by myotonometry. According to our hypothesis, stiffness of upper trapezius muscle will decrease in response to a warm up. Moreover we want to check muscle stiffness changes related to participation in swimming competition. Material and methods. Sixteen female and male swimmers participated in our study. To fulfill our aims we conducted a study composed three measurements of upper trapezius muscle stiffness, before and after the warm up and immediately after the race. The muscle stiffness was assessed by using myotonometric measurements with the MyotonPRO device. Results. Upper trapezius muscle stiffness measurement decreased by few points significantly from before the warm up to after the warm up. There were no significant changes in measurements after the race. Conclusions. Our warm up swimming protocol caused significant decrease of muscle stiffness. Our findings could be an important asset for coaches or other researchers investigating swimming-related changes in muscle stiffness.
