Objective assessment of gymnasts’ dynamic posture using the functional movement screen

PURPOSE: To find if gymnasts are prone to injury based on their dynamic stability assessment results. The aim is to verify the observations made with the Functional Movement Screen (FMS) test via objective method – Kinovea, video-analysis software. To the best of the authors’ knowledge, there exists no previous research using the FMS to assess young gymnasts. Furthermore, no scientific report has been published showing a precise analysis of the FMS via Kinovea. The seven movement tests that are used in the FMS have different positions and movements that show us where weaknesses and asymmetries are visible ; therefore, they can help identify an athlete's risk of injury as well as provide the basis of testing for potential injuries. This information may be of benefit to trainers and physiotherapists in the injury prevention protocol. METHODS: The sample consists of 10 adolescent competitive gymnasts (6 male and 4 female) in the mean age of 11.57, height of 138.87 cm, weight of 34.04 kg. The FMS test includes seven subtests: deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, trunk stability push-up and rotary stability. It is used as a diagnostic procedure for assessing postural stability and mobility, and for the broader purpose of preventing professional injury. The movements were recorded by two digital video cameras. Objective assessment was achieved using Kinovea video-analysis software, with the FMS scoring based on criteria established by Cook et al. (2010) and on kinematic equivalents adapted from Whiteside et al., 2016. The results have been analysed by descriptive statistics and presented in tables. RESULTS: The total mean score of the FMS test for the overall sample is 14.12. The average score for males (14.5) is higher than the average score for females (13.75). We can conclude that our participants are not at risk of injury. The lowest average scores were measured in shoulder mobility (1.12), deep squat (1.15) and rotary stability (1.87), while the highest scores were measured in active straight leg raise (2.87), hurdle step (2.41) and in-line lunge (2.41). CONCLUSION: Competitive young gymnasts do not have increased risk of injury, since they have achieved a score higher than 13, which represents the cut-off score for high-school athletes.
