With 10.8% of sports-related injuries affecting the head and neck, evaluating neck strength is vital for detecting muscle weakness and monitoring rehabilitation progress. The purpose of this study was to determine the intrasession and intersession reliability of a strain gauge for measuring neck retraction strength in healthy adult men. Ten male participants (age, 22.7 [2.6]\u00a0y; body mass, 90.8 [13.3]\u00a0kg; height, 184.2 [7.1]\u00a0cm) completed a neck retraction isometric test across 3 testing occasions separated by 7 days. Contraction duration, peak and mean force, impulse, and peak rate of force development were quantified within and between sessions. Contraction duration, peak force, and impulse demonstrated moderate to excellent intra- (intraclass correlation coefficient [ICC] [3,1]\u2009=\u2009.72\u2013.98, coefficient of variation [CV]\u2009=\u20092.7%\u20132.1%) and intersession reliability (ICC [3,<jats:italic>k<\/jats:italic>] = .66\u2013.89, CV\u2009=\u20094.8%\u20137.1%); however, only acceptable intrasession reliability was found for peak rate of force development and mean force (ICC\u2009=\u2009.71\u2013.99, CV\u2009=\u20093.4%\u201322.7%). It appears that a portable fixed strain gauge can be used to reliably measure neck retraction strength in a healthy male population.<\/jats:p>","DOI":"10.1123\/jsr.2024-0137","type":"journal-article","created":{"date-parts":[[2025,2,14]],"date-time":"2025-02-14T18:04:15Z","timestamp":1739556255000},"page":"595-600","source":"Crossref","is-referenced-by-count":0,"title":["Intrasession and Intersession Reliability of Neck Retraction Strength Using a Strain Gauge Device"],"prefix":"10.1123","volume":"34","author":[{"given":"Josh","family":"Burkitt","sequence":"first","affiliation":[{"name":"Sports Performance Research Institute New Zealand, Faculty of Health and Environmental Sciences, Auckland University of Technology, Auckland, New Zealand"},{"name":"University of Bath, Bath, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4143-1942","authenticated-orcid":true,"given":"Chloe","family":"Ryan","sequence":"additional","affiliation":[{"name":"Sports Performance Research Institute New Zealand, Faculty of Health and Environmental Sciences, Auckland University of Technology, Auckland, New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dana","family":"Ye-Lee","sequence":"additional","affiliation":[{"name":"Sports Performance Research Institute New Zealand, Faculty of Health and Environmental Sciences, Auckland University of Technology, Auckland, New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8889-0911","authenticated-orcid":true,"given":"John","family":"Cronin","sequence":"additional","affiliation":[{"name":"Sports Performance Research Institute New Zealand, Faculty of Health and Environmental Sciences, Auckland University of Technology, Auckland, New Zealand"},{"name":"Athlete Training and Health, Katy, Houston, Texas, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"1","key":"r1","series-title":"Clin Biomech","doi-asserted-by":"publisher","first-page":"11","DOI":"10.1016\/S0268-0033(97)00057-0","article-title":"Critical load of the human cervical spine: an in vitro experimental study","volume":"13","author":"Panjabi MM","year":"1998","unstructured":"Panjabi MM, Cholewicki J, Nibu K, Grauer J, Babat LB, Dvorak J.
