Determining the normative value of the Functional Movement Screen™ in weightlifters in participating gyms within the eThekwini municipality, and its association to injury

Abstract

Background: Weightlifting is an increasing popular form of fitness. Weightlifters train exceptionally hard in their daily training regimes, as well as for competitions. Despite the popularity of this high intensive and explosive training, there is no normative value determined for weightlifters in the eThekwini Municipality, South Africa, to compare themselves against and track their progress or regression or to use as a benchmark when beginners adopt a new training programme. The Functional Movement Screen (FMS™) is a pre-participation assessment which analyses the movements of its participants according to seven exercises, which form the basics of fundamental movement patterns. This assessment allows an analysis of dysfunctional movement patterns to be identified. Aims: The aim of this study has been to assess weightlifters according to the Functional Movement Screen™ (FMS™), to determine a normative value and examine their FMS™ score in relation to prior injury or musculoskeletal dysfunction. Methods: The methodology of this study included assessing 89 weightlifters from participating gym on the FMS™ in order to achieve a normative score of weightlifters within the eThekwini Municipality. Thereafter, participants were contacted telephonically and asked to provide information about their age, height, weight, number of years training, and an injury profile, including how long ago any injury occurred, how long the injury took to heal, the severity of the injury according to the pain rating numerical scale and what form of treatment they received for their injury. The mean FMS™ was then determined for the weightlifters within the eThekwini Municipality and an analysis was made between FMS™ score and injury sustained to determine whether the FMS™ is able to predict injury in this population. Results: The sample population of 89 revealed that the mean FMS™ score for weightlifters in participating gyms within the eThekwini Municipality is 13.88 out of 21. There is no correlation made between FMS™ score and injury and therefore there is no association to injury and FMS™ score in this sample population. There are significant findings in the scoring of the FMS™ exercises showing that weightlifters adapt their own lifting technique in order to lift their desired weight at the velocity expected. The most common recorded injuries are to the shoulder, followed by the knee. The most common injury sustained is musculature in nature and the most common treatment received for injury was physiotherapy. Conclusion: The normative value for weightlifters in participating gyms within the eThekwini Municipality is 13.88 out of 21 for the FMS™. It has been established that weightlifters deviate from the ideal movement pattern to develop stability and strength to lift their desired weights at explosive outputs. There was no link found between FMS™ score and injury and no correlation made between age, height, weight and number of years training and the FMS™ score.
