Resumo: | In Brazil, it is estimated a 30-fold increase in the number of runners in the last 15 years. This growing number of practitioners has been noticed all over the world. It is known that most of the injuries that occur during this activity involves the knee joint (42,1%) and, the Patellofemoral Pain (PFP) is the commonest. Recently, it has been hypothesized that running technique modification (such as, landing with the forefoot on the ground [FFOOT], increasing 10% of the step rate [10% SR] and increasing the trunk flexion [TFLEX]) has the potential to reduce the demand on the knee joint. However, no study evaluated the effects of these running techniques on the lower limb and trunk three-dimensional joint kinematics and on comfort reported by runners. Thus, this study aimed to evaluate the immediate effects FFOOT, 10% SR and TFLEX on the trunk, hip, knee and ankle kinematics and on the subjective assessment of comfort during running. Thirty-one healthy rearfoot strike-landing runners (20 males, 11 females) were evaluated. For such, the Qualisys Motion Capture System was used to collect data during Usual Running (USRUN) and the other three running techniques and, a visual analogue scale was used to evaluate comfort in each condition. The variables of interest were collected during initial foot contact on the treadmill. For statistical analysis, it was used the multivariate analysis of variance (MANOVA) with repeated measures (alpha level of 0.05). During the FFOOT, it was shown reduction in the knee external rotation (P < 0.001), hip flexion (P < 0.001), adduction (P = 0.001), internal rotation (P < 0.001), greater knee adduction (P = 0.016), knee flexion (P < 0.001) and plantar flexion (P < 0.001). The 10% SR demonstrated diminished knee external rotation (P = 0.001), hip internal rotation (P = 0.008) and, hip flexion (P = 0.001), however, there was greater knee flexion (P = 0,042). The TFLEX increased knee adduction (P = 0.001), hip flexion (P < 0.001), trunk flexion (P < 0.001), but decreased plantar flexion (P = 0.003). The USRUN was the most comfortable technique (P = 0.033 0.002). Therefore, we were to conclude that the three running technique modifications can minimized the knee and hip movements in the frontal and transverse planes that are associated with greater stress on the patellofemoral joint. In addition, the FFOOT and 10% SR techniques resulted in increased knee flexion that could improve the impact forces absorption. It is believed that a gradual transition to these running techniques may improve comfort. |

Esse crescente número de praticantes é observado em todo o mundo. Sabe-se que o maior número de lesões nesta atividade envolve a articulação do joelho (42,1%) sendo a Dor Patelofemoral (DPF) a disfunção mais comum nessa articulação. Recentemente, têm sido hipotetizado que a modificação da técnica de corrida (tal como a aterrissagem com o antepé no solo [CAA], o aumento de 10% na frequência da passada [CFP10] e o aumento da flexão do tronco [CFT]) apresenta potencial de reduzir a demanda na articulação do joelho. Entretanto, não há estudos que avaliaram a influência dessas técnicas de corrida na cinemática articular tridimensional do membro inferior e do tronco e no conforto relatado por corredores. Dessa forma, o objetivo do presente estudo foi avaliar os efeitos imediatos da CAA, CFP10 e CFT na cinemática do tronco, quadril, joelho e tornozelo e na percepção de conforto durante a corrida. Foram avaliados 31 corredores sadios, com padrão de aterrissagem iniciado pelo retropé (20 homens, 11 mulheres). Para tal, a corrida habitual (CHAB) e as 3 técnicas de corrida foram coletadas utilizando o sistema de captura e análise do movimento Qualisys Motion Capture System e, uma escala visual analógica foi utilizada para a avaliação do conforto em cada condição. As variáveis de interesse foram obtidas no contato inicial do pé na esteira ergométrica. Para análise estatística foi utilizado o teste de análise de variância multivariada (MANOVA) com medidas repetidas (nível de significância de 5%). Durante a execução da CAA, foi observada diminuição da rotação lateral do joelho (P<0,001), da flexão (P<0,001), da adução (P=0,001), e da rotação medial do quadril (P<0,001) e, aumento da adução (P=0,016) e da flexão de joelho (P<0,001) e da flexão plantar do tornozelo (P<0,001). A CFP10 diminuiu a rotação lateral do joelho (P=0,001) e a rotação medial (P=0,008) e a flexão do quadril (P=0,001), porém aumentou a flexão do joelho (P=0,042). A CFT aumentou a adução do joelho (P=0,001), a flexão do quadril (P<0,001) e a flexão do tronco (P<0,001), mas diminuiu a flexão plantar do tornozelo (P=0,003). A CHAB foi a técnica mais confortável (P=0,033 P=0,002). Assim, é possível concluir que as 3 modificações da técnica de corrida são capazes de minimizar os movimentos do joelho e quadril nos planos frontal e transversal relacionados ao aumento do estresse patelofemoral. Além disso, a CAA e a CFP10 resultaram em aumento da flexão do joelho, o que pode contribuir com uma melhor absorção das forças de impacto. Acredita-se que após uma adaptação gradual com as modificações da técnica de corrida, o conforto relatado possa ser aumentado.Universidade Federal de Sao Carlosapplication/pdfporUniversidade Federal de São CarlosPrograma de Pós-Graduação em Fisioterapia - PPGFtUFSCarBRFisioterapiaBiomecânicaAterrissagem com antepéFrequência da passadaFlexão do troncoConforto humanoPadrão de corridaBiomechanicsRunning patternForefoot strike landingStep rateTrunk flexionComfortCIENCIAS DA SAUDE::FISIOTERAPIA E TERAPIA OCUPACIONALEfeitos imediatos de três modificações da técnica de corrida na cinemática do membro inferior e tronco e no conforto em corredores sadios: um estudo experimentalinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesis-1-1ee598887-0326-4638-bbde-7861b1bc5850info:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSCARinstname:Universidade Federal de São Carlos (UFSCAR)instacron:UFSCARORIGINAL5753.pdfapplication/pdf2217344https://repositorio.ufscar.br/bitstream/ufscar/5325/1/5753.pdf0fb3595b520f776853349e4095faa810MD51TEXT5753.pdf.txt5753.pdf.txtExtracted texttext/plain0https://repositorio.ufscar.br/bitstream/ufscar/5325/2/5753.pdf.txtd41d8cd98f00b204e9800998ecf8427eMD52THUMBNAIL5753.pdf.jpg5753.pdf.jpgIM Thumbnailimage/jpeg8534https://repositorio.ufscar.br/bitstream/ufscar/5325/3/5753.pdf.jpg520c27e6a3f2a5b09a8d1c8ee6f13af2MD53ufscar/53252023-09-18 18:31:35.928oai:repositorio.ufscar.br:ufscar/5325Repositório InstitucionalPUBhttps://repositorio.ufscar.br/oai/requestopendoar:43222023-09-18T18:31:35Repositório Institucional da UFSCAR - Universidade Federal de São Carlos (UFSCAR)false |
