Resumo: The patellar tendon is one of the most relevant in the human body because of its fundamental importance in gait and orthostatism. Its mechanical properties are closely related to quadriceps function, its usual overload and training programs to which it is subjected. This study evaluates the adaptation of the patellar tendon´s shear modulus to an 8-week resistance training program, using supersonic shear wave imaging (SSI) elastography in 15 healthy young men. In addition, the variations of the vastus lateralis´ shear modulus and thickness, the morphological adaptations of the patellar tendon and the increase of knee extensor torque were measured using B-mode ultrasound and dynamometry. The observed results attest the efficiency of the resistance training program applied to promote strength gains and hypertrophy, but did not reveal statistically significant adaptations in the shear modulus or thickness of the patellar tendon. A pronounced and statistically significant increase was observed in the vastus lateralis´ shear modulus. This study may serve as a basis for further investigations into intervention protocols aimed to adapt the knee extensor mechanism for injury prevention, rehabilitation or conditioning.

Suas propriedades mecânicas estão intimamente relacionadas à função do quadríceps, sua sobrecarga habitual e aos programas de treinamento ao qual é submetido. Este trabalho avalia a adaptação do módulo de cisalhamento do tendão patelar a um programa de treinamento resistido de oito semanas através do uso da elastografia supersonic shear wave imaging (SSI), em 15 homens jovens e saudáveis. Além disso, foram mensuradas as variações do módulo de cisalhamento e espessura do vasto lateral, as adaptações morfológicas do tendão patelar e o aumento do torque extensor do joelho utilizando o ultrassom modo B e dinamometria. Os resultados observados atestam a eficiência do treinamento aplicado em promover aumento de força e hipertrofia no músculo alvo, porém não revelaram adaptações estatisticamente significantes no módulo de cisalhamento ou espessura do tendão patelar. Foi observada um aumento pronunciado e estatisticamente significante no módulo de cisalhamento do vasto lateral. Esse estudo pode servir de base para ulteriores investigações sobre protocolos de intervenção que visam adaptar o mecanismo extensor do joelho para prevenção de lesões, reabilitação ou condicionamento.Universidade Federal do Rio de JaneiroBrasilInstituto Alberto Luiz Coimbra de Pós-Graduação e Pesquisa de EngenhariaPrograma de Pós-Graduação em Engenharia BiomédicaUFRJOliveira, Liliam Fernandes dehttp://lattes.cnpq.br/5261830927402052http://lattes.cnpq.br/2864231995487246Dias, Ingrid Bárbara FerreiraAlbuquerque, Rodrigo Sattamini Pires eMatta, Thiago Torres daPereira, Wagner Coelho de AlbuquerqueMannarino, Pietro2020-10-14T18:12:53Z2023-12-21T03:02:22Z2019-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesishttp://hdl.handle.net/11422/13235enginfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFRJinstname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJ2023-12-21T03:02:22Zoai:pantheon.ufrj.br:11422/13235Repositório InstitucionalPUBhttp://www.pantheon.ufrj.br/oai/requestpantheon@sibi.ufrj.bropendoar:2023-12-21T03:02:22Repositório Institucional da UFRJ - Universidade Federal do Rio de Janeiro (UFRJ)false
