outcomes of a scientist translate successfully into exceptional sporting performance, this brings profile and reputation that can generate more research activity and funding. While this is nice for successful athletes and supporting scientists, it can lead to an imbalance of research output in the various

limitations, muscle imbalances, and asymmetries. 5 , 6 Conventionally, it is used to evaluate athletes’ functional movements before the season begins. Previous studies have shown that athletes who recorded lower FMS scores tended to have higher risk of injuries. 7 – 9 In addition to use as a screening tool

one AT did not believe a player’s performance was affected by hydration status and four did not believe electrolyte imbalance affected performance (Table  2 ). There were no significant associations for when ATs believed hydration was most influential. “Other” hydration assessment techniques included
