Although it seems basic, it reflects overall upper-body strength and is widely used in both sports science and healthcare.\n\nIn this project, players from different levels of ice hockey (including professional men's and women's leagues, junior players, and recreational players if available) will have their grip strength measured using a standardized hand dynamometer. Measurements will be taken in a consistent way across all participating clubs.\n\nThe main goal is to build a reference database showing what \"normal\" grip strength looks like in ice hockey players depending on sex, league level, and playing position. This can help coaches, medical staff, and researchers better understand strength profiles in hockey athletes, support training and rehabilitation decisions, and provide benchmarks for future studies.\n\nNo treatment or intervention is given as part of the study.",[39,40,9],"Grip Strength","Normative Values",[42,43,44,45],"ice hockey","athletes","grip strength","normative data","NOT_YET_RECRUITING","2026-05-22",{"date":49,"type":50},"2026-05-27","ACTUAL",{"date":52,"type":35},"2026-09-01",{"date":54,"type":35},"2026-12-31",{"name":5,"class":6}]
