It is often used in sports science and clinical settings, but it is unclear whether grip strength remains stable throughout a season or changes depending on training load, match exposure, and fatigue.\n\nIn this study, elite ice hockey players from Swedish teams will have their grip strength measured at four timepoints during one season: pre-season, early season, mid-season, and late season. Both dominant and non-dominant hand strength will be assessed using a standardized dynamometer and protocol.\n\nThe main purpose is to determine how much grip strength varies within individual players over time and whether a single measurement can be considered representative of a player's true strength level across a season. The study will also evaluate the reliability of grip strength measurements and whether observed changes are large enough to be meaningful in a clinical or performance context.\n\nNo intervention is performed, and all measurements are non-invasive and conducted as part of routine testing environments within participating teams.",[24,25,26],"Ice Hockey","Grip Strength","Within-season Variability",[28,29,30,31],"ice hockey","hand grip strength","within-season variability","test-retest reliability","NOT_YET_RECRUITING","2026-06-04",{"date":35,"type":36},"2026-06-05","ACTUAL",{"date":38,"type":20},"2026-09",{"date":40,"type":20},"2027-12-31",{"name":42,"class":43},"Dalarna County Council, Sweden","OTHER",1,{"id":46,"slug":47,"hasResults":11,"nctId":48,"briefTitle":49,"officialTitle":49,"acronym":4,"eligibilityCriteria":50,"healthyVolunteers":11,"sex":16,"minAge":51,"maxAge":4,"enrollmentInfo":52,"targetDuration":4,"studyType":21,"phases":4,"briefSummary":54,"conditions":55,"keywords":58,"overallStatus":32,"whyStopped":4,"lastUpdateSubmitDate":62,"lastUpdatePostDateStruct":63,"startDateStruct":65,"completionDateStruct":67,"leadSponsor":69,"locationsCount":4},"100636581","normative-hand-grip-strength-values-in-swedish-male-and-female-ice-hockey-players-across-competitive-levels-100636581","NCT07567547","Normative Hand Grip Strength Values in Swedish Male and Female Ice Hockey Players Across Competitive Levels","Inclusion Criteria:\n\n* Adult male or female ice hockey players.\n* Registered and actively participating in a Swedish ice hockey club during the current season.\n* Participation in one of the included competitive levels: professional, semi-professional, junior elite, or recreational leagues in Sweden.\n* Able to perform maximal hand grip strength testing.
