Stress-related psychosocial factors at work, fatigue, and risky driving behavior in bus rapid transport (BRT) drivers
2016
Abstract Introduction There is consistent scientific evidence that professional drivers constitute an occupational group that is highly exposed to work related stressors. Furthermore, several recent studies associate work stress and fatigue with unsafe and counterproductive work behaviors. This study examines the association between stress-related work conditions of Bus Rapid Transport (BRT) drivers and risky driving behaviors; and examines whether fatigue is a mechanism that mediates the association between the two. Method A sample of 524 male Bus Rapid Transit (BRT) operators were drawn from four transport companies in Bogota, Colombia. The participants answered a survey which included an…
Association between physiological stress and skin temperature response after a half marathon
2019
OBJECTIVE: The objective of this study was to determine the association between skin temperature response and the physiological stress after a half marathon. APPROACH: Seventeen runners were measured 48 h before, 24 h before, 24 h after and 48 h after completing a half marathon. The measurements on each day of testing included blood markers (creatine kinase [CK] and glutamate oxaloacetate transaminase [GOT]), perception of pain and fatigue (using a visual analogue scale), skin temperature (using infrared thermography), and jump performance (using countermovement jump test). MAIN RESULTS: CK (p 1.0) increased 24 h after the half marathon, whereas jump performance decreased (p < 0.01 a…
Work stress, fatigue and risk behaviors at the wheel: Data to assess the association between psychosocial work factors and risky driving on Bus Rapid…
2017
This Data in Brief (DiB) article presents a hierarchical multiple linear regression model that examine the associations between psychosocial work factors and risk behaviors at the wheel in Bus Rapid Transit (BRT) drivers (n=524). The data were collected using a structured self-administrable questionnaire made of measurements of wok stress (job strain and effort- reward imbalance), fatigue (need for recovery and chronic fatigue), psychological distress and demographics (professional driving experience, hours driven per day and days working per week). The data contains 4 parts: descriptive statistics, bivariate correlations between the study variables and a regression model predicting risk be…
Evaluación de una Intervención Mindfulness en Equipos de Cuidados Paliativos
2018
Resumen: El objetivo de este estudio es evaluar los resultados de un programa breve de entrenamiento en mindfulness sobre la atención plena, la autocompasión y la calidad de vida profesional en equipos de cuidados paliativos. Para ello se llevó a cabo un estudio preexperimental pre-post. Participaron 36 profesionales de equipos de cuidados paliativos de Madrid (España). Se midió mindfulness, autocompasión y calidad de vida profesional. Las mediciones se realizaron al inicio y a las dos semanas de finalizada la intervención, que duró seis semanas. Los resultados de aplicación del programa se evaluaron mediante análisis de varianza multivariados (MANOVA). Tras la intervención se observó una m…

Somnolencia y fatiga materna en los primeros años de crianza y ejecución en la conducción evaluada en simulador
2017
RESUMEN DE LA TESIS DOCTORAL Somnolencia y fatiga materna en los primeros años de crianza y ejecución en la conducción evaluada en simulador El nacimiento de un bebé y la crianza posterior durante la primera infancia supone un considerable esfuerzo para madres y padres, que provoca cambios profundos en la familia, tanto si se trata del primer hijo/a como de la incorporación de un nuevo miembro más a la familia. Un bebé recién nacido necesita atención constante por parte de sus cuidadores, y los padres deben responder a las intensas demandas de cuidado que requiere, sobre todo porque el bebé no tiene un ritmo circadiano establecido, su sueño se distribuye a lo largo del día y de la noche en …
Altérations neuromusculaires induites par des exercices excentriques et concentriques fatigants : emphase sur le pédalage des membres inférieurs
2021
The influence of dynamic contraction type (concentric or eccentric) on performance fatigability and associated neuromuscular alterations is partly unknown. Contraction type interacts with other exercise features such as intensity (maximal; submaximal) or modality (single-joint; locomotor). Thus, we compared eccentric with concentric exercises of similar characteristics across three experimental studies. We showed that, for the completion of a given amount of mechanical work, both contraction types impaired maximal voluntary isometric torque similarly. However, neuromuscular impairments depended on exercise features. In study 1, maximal single-joint eccentric contractions affected neural but…

Premolars restored with posts of different materials: fatigue analysis
2011
Previous works studied the effect of the material and the dimensions of the post on the biomechanical performance (fracture strength and stress distribution) of restored teeth, under static loads. The aim of this work was to study the effect of the post material (glass fibre and stainless steel) on restored teeth, which have the final crown, under dynamic conditions. The use of a biomechanical model, including a fatigue analysis from FEA, is presented as a powerful method to study the effect of the material of the intraradicular post. The inclusion of the fatigue analysis allows for a more realistic study that takes into account the dynamic nature of masticatory forces. At the same time, th…
Estudio preliminar de la activación neuromuscular corriendo descalzo y calzado = Preliminary study of the neuromuscular activation during barefoot an…
2015
El objetivo del presente estudio preliminar fue comparar la actividad muscular de los músculos tibial anterior, peroneo lateral largo, gastrocnemio medial y gastrocnemio lateral entre la carrera con y sin calzado, y la influencia de la fatiga. 7 participantes realizaron una carrera de fatiga de 20 minutos al 75% de su velocidad aeróbica máxima en cinta con 1% de pendiente. Se midió la actividad mioeléctrica de los músculos antes mencionados tanto antes como después de la prueba de fatiga en dos condiciones: con calzado y sin calzado. Los resultados mostraron una mayor actividad del tibial anterior durante la carrera en fatiga descalzo respecto a la carrera calzado y una mayor actividad del …
