Tendon stiffness, the relationship between force applied to a tendon and the resulting displacement, has been identified as a primary mechanical factor in such injuries. However, patellar tendon stiffness has not yet been evaluated in elite breakdancers. Hence, the purpose of this study was to determine mean patellar tendon stiffness in this population by using myotonometric measurements and to compare those results with healthy control subjects. Twenty-five elite male breakdancers and 25 male control subjects were included in the study. A Myoton Pro device was used to assess their tendon stiffness. The mean patellar tendon stiffness of the breakdancers was 1,045 \u00b1 202 Nm and 1,084 \u00b1193 Nm for the dominant and non-dominant limb, respectively; for the control group it was 902 \u00b1166 Nm and 862 \u00b1159 Nm for the dominant and non-dominant limb, respectively. Statistical analyses showed higher stiffness values for breakdancers compared to controls for both limbs. This is consistent with studies reporting patellar tendon adaptation after training.<\/jats:p>","DOI":"10.12678\/1089-313x.22.4.179","type":"journal-article","created":{"date-parts":[[2018,11,26]],"date-time":"2018-11-26T23:42:01Z","timestamp":1543275721000},"page":"179-183","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":20,"title":["Patellar Tendon Stiffness in Elite Breakdancers Assessed by Myotonometric Measurement"],"prefix":"10.1177","volume":"22","author":[{"given":"Fiorella Celsi","family":"Young","sequence":"first","affiliation":[{"name":"Escuela de Medicina, Facultad de Medicina, Universidad de los Andes, Santiago, Chile."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iver","family":"Cristi-S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Escuela de Kinesiolog\u00eda, Facultad de Ciencias, Universidad Mayor, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Danes-Daetz","sequence":"additional","affiliation":[{"name":"Laboratorio Integrativo de Biomecan\u00edca y Fisiolog\u00eda del Esfuerzo, Escuela de Kinesiolog\u00eda, Facultad de Medicina, Universidad de los Andes, Santiago, Chile."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan E.","family":"Monckeberg","sequence":"additional","affiliation":[{"name":"Cl\u00ednica MEDS, Santiago, Chile."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rony Silvestre","family":"Aguirre","sequence":"additional","affiliation":[{"name":"Cl\u00ednica MEDS, Santiago, Chile."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2018,12]]},"reference":[{"issue":"11","key":"e_1_2_1_2_2","doi-asserted-by":"crossref","first-page":"1207","DOI":"10.1016\/j.injury.2009.05.019","article-title":"Musculoskeletal injuries in break-dancers.","volume":"40","author":"Cho CH","year":"2009","unstructured":"Cho CH, Song KS, Min BW, .
