Behaviour of vastus lateralis muscle-tendon during high intensity SSC exercises in vivo
2003
Aims: The interaction between fascicle and tendinous tissue of human vastus lateralis muscle was investigated during varying intensity stretch–shortening cycle (SSC) jumps performed on a sledge apparatus. Methods: Eight subjects performed single leg squat (SJ) and drop jumps (DJ) from a constant dropping height but to different rebound heights. The fascicle length of the vastus lateralis muscle (VL) was determined from real-time ultrasonography during the movement. Tendon length changes were calculated by subtracting the horizontal part of the fascicle length from the muscle–tendon unit (MTU) length. Simultaneously, kinematic, kinetic and electromyographic data were recorded from leg musc…
Experimental Characterization of the Human Meniscal Tissue
2018
The meniscus plays a critical role in load transmission, stability and energy dissipation in the knee joint. Loss of the meniscus leads to joint degeneration and osteoarthritis. In a number of cases replacement of the resected meniscal tissue by a synthetic implant might avoid the articular cartilage degeneration. None of the available implants presents optimal biomechanics characteristic due to the fact the biomechanics functionality of the meniscus is not yet fully understood. Mimicking the native biomechanical characteristics of the menisci seems to be the key factor in meniscus replacement functioning. This is extremely challenging due to its complex inhomogeneous microstructure, the la…
Changes in trunk posture and muscle responses in standing during pregnancy and postpartum
2018
Este artículo se encuentra disponible en la página web de la revista en la siguiente URL: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0194853 The aim of this study was to analyze the position of the lumbopelvic region and the muscle activation of erector spinae and biceps femoris muscles in a group of pregnant women in the third trimester. The hypothesis was that pregnancy-related biomechanical and morphological changes modify the position of the lumbopelvic region and the activation of extensor muscles. The position of the lumbar spine and pelvis in the sagittal plane, and the EMG activity of the erector spinae and biceps femoris muscles, were recorded during standing…
Some subgroup embeddings in finite groups
2015
In this survey paper several subgroup embedding properties related to some types of permutability are introduced and studied.
40m sprint mechanics dataset male and female athletes UiA/Olympiatoppen
2020
This data is collected on over 600 Norwegian athletes from different sports performing 40m sprint tests under highly controlled conditions. The data was collected as part of training monitoring. The data forms the background for several published studies.
Analysis of the conflicts of interest disclosed by the program reviewers of the scoliosis research society (SRS) congresses, 2010-2014.
2018
Background Conflicts of interest (COI) between industry and surgeons frequently introduce biases into surgical research. The abstracts submitted for presentation in scientific congresses are usually vetted for any indication of commercial bias. Members of review program committees regularly have recognized qualifications, and therefore certain COI are unavoidable. This study aims to determine the prevalence and magnitude of possible COI among those responsible for the selection of presentations at two important international conferences on spine surgery during a five-year period. Methodology COI declarations by those responsible for the final programs of the annual SRS (Scoliosis Research S…
Intervención de ergonomía participativa en una empresa del sector químico
2012
ResumenSe describe una intervención de ergonomía participativa iniciada en abril de 2010 en una empresa del sector químico de la Comunidad Valenciana. Se presentó el programa de intervención en la empresa, se acordó el ámbito de la intervención (dos líneas, 24 trabajadores y trabajadoras) y se constituyó un grupo de trabajo (Grupo Ergo, formado por personas responsables, técnicos y delegados de prevención de la empresa) encargado de guiar la intervención. Se recogió mediante cuestionario información acerca de daños y riesgos ergonómicos en los trabajadores y trabajadoras de los puestos seleccionados. Esta información fue analizada por el Grupo Ergo y discutida posteriormente en círculos de …
How to keep your staff healthy in the educational sector?
2021
The purpose of the paper is to identify risks and challenges for alternative forms of work during online classes for teaching personnel. Musculoskeletal disorders (MSD) affect the body’s bones, muscles, joints, ligaments/tendons, and nerves. Musculoskeletal health risk in the educational sector should be taken into consideration to ensure the safety and healthy employees, especially when online classes require a physical inactivity and a prolonged sitting in front of the computer. MSD management requires an integrated approach integrating wellbeing with a focus on prevention, recognizing physical, social and emotional influences and early intervention. Workplace wellness has been a valuable…
Osteolisis tibial secundaria a un implante ligamentoso de Leeds-Keio: Presentación de un caso
2002
Hasta hace algunos años, el ligamento artificial de Leeds-Keio, se usó en muchos casos para la reconstrucción de lesiones del ligamento cruzado anterior. Hoy día no se usa para este tipo de lesiones debido a los pobres resultados que se observaron a medio y largo plazo. No obstante, su uso está indicado en otras lesiones, como son la reconstrucción del aparato extensor de la rodilla, y en inestabilidades del hombro y de la columna vertebral. Presentamos un caso de osteolisis masiva del platillo tibial que requirió la retirada del implante seguida de autoinjerto óseo, complicación que no ha sido comunicada anteriormente Some years ago the Leed-Keio prosthesis was widely used for anterior cru…
Traumatismos de partes blandas en la muñeca: cobertura fasciocutánea
2005
Las pérdidas de sustancia traumática localizadas en la muñeca afectan frecuentemente a los tendones, vasos y nervios. Estas lesiones requieren un tratamiento reparador de las estructuras lesionadas y una cobertura adecuada que permita el deslizamiento de los tendones, y proporcione protección neurovascular segura. El colgajo fasciocutáneo basado en perforantes de la arteria cubital aporta piel, tejido subcutáneo y fascia sobre las estructuras expuestas en la muñeca tanto en la cara palmar como dorsal. Presentamos cuatro casos de traumatismos de partes blandas en la muñeca, en ellos tras la reparación neurotendinosa requerida, se optó por la cobertura final mediante el colgajo fasciocutáneo …
