Ultrasound shear wave elastography provides quantifiable and specific data regarding muscle stiffness. The purpose of this study was to compare tendon and muscle stiffness in healthy tennis players to nontennis players. <jats:italic><jats:bold>Design<\/jats:bold>:<\/jats:italic> Cross-sectional study. <jats:italic><jats:bold>Methods<\/jats:bold>:<\/jats:italic> The shear wave modulus, measured in kilopascals, was obtained for the dominant pectoralis major, pectoralis minor, and common wrist-extensor tendon using 2-dimensional shear wave elastography ultrasound imaging (GE Logiq S8, L9 linear transducer). Independent <jats:italic>t<\/jats:italic> test was run to compare age, body mass index, and the activity index score between both groups. Within-day intrarater reliability was assessed using a within-examiner intraclass correlation coefficients (ICC [3, 1]) with 95% confidence intervals. A multivariate general linear model was run to compare the mean differences between the tennis and nontennis players for each of the soft tissues. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> Twenty-six individuals (13 tennis players and 13 nontennis players) were recruited. Within-day ICCs were very good (ICC\u2009&gt;\u2009.78 for the pectoralis musculature) and excellent (ICC\u2009&gt;\u2009.94 for the common wrist extensor). Common extensor tendon stiffness was significantly higher in tennis players compared to nontennis players (mean difference\u2009=\u2009114.8\u2009[61.8], confidence interval, \u221222.8 to 252.5\u00a0kPa for the dominant arm [<jats:italic>P<\/jats:italic>\u2009=\u2009.039]). Mean pectoralis major and minor stiffness differences were not significant (<jats:italic>P<\/jats:italic>\u2009&gt;\u2009.214). <jats:italic><jats:bold>Conclusions<\/jats:bold>:<\/jats:italic> Common wrist-extensor stiffness in healthy recreational tennis players is higher than those who do not play tennis. Therefore, clinicians may need to facilitate a greater soft tissue stiffness response with resistance training when rehabilitating recreational tennis players as compared to those not playing tennis. Additional normative data on a larger sample of recreational tennis players should be collected.<\/jats:p>","DOI":"10.1123\/jsr.2023-0202","type":"journal-article","created":{"date-parts":[[2024,2,20]],"date-time":"2024-02-20T17:00:59Z","timestamp":1708448459000},"page":"174-180","source":"Crossref","is-referenced-by-count":6,"title":["Common Wrist-Extensor Tendon and Pectoralis Muscle Stiffness in Healthy Recreational Tennis Players"],"prefix":"10.1123","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2913-2352","authenticated-orcid":true,"given":"Joseph M.","family":"Day","sequence":"first","affiliation":[{"name":"Department of Physical Therapy, University of Dayton, Dayton, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harold","family":"Merriman","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, University of Dayton, Dayton, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"7","key":"r1","series-title":"Br J Sports Med","doi-asserted-by":"publisher","first-page":"492","DOI":"10.1136\/bjsports-2012-091164","article-title":"Epidemiology of musculoskeletal injury in the tennis player","volume":"46","author":"Abrams GD","year":"2012","unstructured":"Abrams GD, Renstrom PA, Safran MR.
