“…The hurdle step, in‐line lunge, shoulder mobility, active straight leg raise, and rotary stability subtests assess for movement asymmetry. Fuller et al reported a high percentage (65%) of elite junior Australian football players demonstrated at least one asymmetrical movement during FMS testing. Moreover, we demonstrated that the presence of ≥2 asymmetrical FMS subtests was associated with a threefold (Hazard ratio = 3.7; Relative risk = 2.8) increase in the risk of injury that caused a missed game in 237 elite junior male Australian football players .…”

An indicator of movement quality and potential injury risk during Functional Movement Screen (FMS) testing is the presence of asymmetry when comparing the left and right sides of the body. The aim of the study was to investigate the reproducibility of the injury risk model proposed in our previous research (Chalmers et al. 2017; derivation study) that showed an increased injury risk for elite junior Australian football players demonstrating ≥2 asymmetrical FMS subtests. We used a direct replication design. Players underwent pre-season FMS testing, and an injury surveillance system monitored 277 male participants during the subsequent regular season competition. Designated club officials monitored the weekly competition participation of players. The definition of an injury was "a trauma or medical condition which caused a player to miss a competitive game". Cox proportional hazards regression models were used to investigate the relationship between asymmetry and number of games played before first injury (ie, survival time). The level of reproducibility was determined according to statistical significance, effect size, and subjective assessment. Demonstrating asymmetry during FMS testing was not associated with a significant increase in prospective injury risk in the replication study (P > .05). Moreover, effect sizes (hazard ratios) from the derivation dataset were not within the 95% confidence intervals of the respective asymmetry predictor in the replication dataset. Subjectively, researchers were in agreement that the findings from the derivation data were not successfully reproduced. Clinicians and researchers should be cautious about using FMS asymmetry findings to derive injury risk for junior football players.

“…The subjects who scored ≤14 in performing functional movement tests were attributed to Group 1 and were considered to have a greater chance of trauma (the composite score for women was 13.00 (12.41-12.82) and that for men was 13.00 (11.99-12.81)). The subjects who scored ≥15 were attributed to Group 2 and were considered to have a lower chance of trauma (the composite score for women was 15.00 (15.47-16.17) and that for men was 16.00 (15.56-16.14)) [27][28][29]33].…”

“…The subjects performed the following movements: deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, trunk stability push-up and rotary stability. Following many authors [27][28][29], the reference point is as follows: subjects with the score ≤14 have a greater chance of trauma (Group 1), and those with the score ≥15 have a lower chance of trauma (Group 2). In case of different evaluation scores for the left and the right body sides, the subjects were attributed to the groups according to the lower score [30].…”

Asymmetry of body parts refers to absence of symmetry and unevenly developed body parts in terms of the axis and plane. It has been long ago noticed that no perfectly correct human body exists, and bodies are to a greater or lesser extent asymmetric. A passive way of life, insufficient movement and inappropriate ergonomics of the workplace have a negative impact on the skeletal muscle system, usually resulting in reduced muscle power, static and dynamic muscle endurance, and altered muscle tone. The aim is to determine whether muscle myotonometry parameters are informative in early risk diagnostics to predict the likelihood of skeletal muscle system trauma. The study involved 382 people aged 18-24. Participants were devided into two groups: according to the accumulated composite score. Testing was made one time. The study consisted of functional movement and myotonometry evaluation. The study analyses and presents comparisons of the results depending on the trauma likelihood and sex. In addition, asymmetry of the left and the right body side is investigated. The analysis of the asymmetries (delta) in the frequency of damped oscillations of trapezius, biceps femoris, gastrocnemius (inner and outer part) on the left and right sides of the body demonstrated greater asymmetries between the left and the right sides of the body in the groups of both men and women with a lower chance of trauma. The assessment of asymmetries in femoris rectus and tibialis anterior between the left and the right sides of the body showed differences in the frequency of damped oscillations in all groups. Muscle myotonometry parameters are informative and may be used in early risk diagnostics to predict skeletal muscle system trauma. The asymmetry in tibialis muscle tone between the left and the right leg causes poorer parameters of functional movement performance in women. No associations were found to exist with the ability to perform functional movements in men. The asymmetry in femoris muscle tone between the left and right leg demonstrates the ability of young subjects to perform functional movements. It is characteristic of men and, to a lower extent, of women.

“…Lower FMS scores are found to be related to higher injury rates in sports such as soccer, ice hockey, Australian football, rugby, and running (8)(9)(10). Moreover, the normative values of the FMS scores are established in lesser populated sports as Hurling and Gaelic football (11).…”

Purpose: Handball is one of the team sports that common injuries reported. Movement analyses and detecting functionally limited areas have been of utmost importance for eliminating injury risks. This study aimed to determine the injury risks and compare them according to field positions in young Turkish elite male handball players. Methods: Fifty-four players (age=15.69±0.47 years, height=182.80±6.53 cm, weight=82.09±14.28 kg, body mass index=24.52±3.77 kg/m 2) who were invited to the U17 National Handball Team participated in the study. Descriptive data with physical characteristics were obtained. Injury risk was assessed using the Functional Movement Screen (FMS) test, Y-Balance Test (YBT)-Upper Extremity, and YBT-Lower Extremity tests. The overall scores for FMS, YBT-Upper Extremity, and YBT-Lower Extremity were calculated for all subjects. Results: The field positions were distributed as goalkeepers (n=7), back players (n=24), wing players (n=13), and pivots (n=10). Based on the field positions, pivots and goalkeepers were determined as having the lowest scores regarding FMS and YBT-Upper Extremity (p<0.05). Conclusion: Players who compete in the positions of goalkeeper and pivot might have higher injury risk due to lower FMS and YBT-Upper Extremity scores. These results would allow the trainers and players to observe the current status and to implement the injury prevention programs.
