Modelling Physical Fatigue Through Physiological Monitoring Within High-Risk Pr...
Bustos, D; Cardoso, F; Cardoso, R; Guedes, J. C.; José Castela Costa; Mário Vaz; João Santos Baptista; Fernandes, JPhysical fatigue is not only a tiredness condition but can also be a symptom of various diseases or a precursor of workplace accidents and incidents. High-risk professions like firefighters and military personnel are more frequently exposed to it and its consequences. To contribute to current research efforts towards physical fatigue quantification approaches for these professionals, the current work aimed to t...
Cardiopulmonary, Metabolic and Perceived Exertion Characteristics Among Portugu...
Bustos, D; Carvalho, D; Rios, M; Guedes, J. C.; José Castela Costa; Mário Vaz; João Santos Baptista; Fernandes, JBackground: Firefighting is a strenuous occupation that requires firefighters to be in excellent physical condition. However, some of these professionals are not sufficiently physically fit for duty, negatively impacting their performance. Objective: To cardiopulmonary characterize Portuguese firefighters at different exercise intensities to clarify if their physical fitness profile is adequate to overcome thei...
Physiological and Thermal Sensation Responses to Severe Cold Exposure (-20 °C)
Zlatar, T; Bustos, D; Costa, JT; Baptista, JS; Guedes, J. C.Various jobs, indoors and outdoors, are subjected to severe cold temperatures during daily activities. Extremely low-temperature exposure and work intensity affect health, safety, and occupational performance. This work aimed to assess the physiological and thermal sensation responses before, during, and following a 60 min exposure to cold (-20 degrees C), during which occupational activities were developed. Us...
Machine Learning Applications for Continuous Improvement in Integrated Manageme...
Yska, S; Bustos, D; Guedes, J. C.The machine learning (ML) field is increasingly impacting industries within the Industry 4.0 paradigm, which among other things, enables the usage of vast amounts of data. Combining data and ML consequently enables continuous improvement that differs from conventional continuous improvement, especially in higher efficiency on default detection. However, scientific literature needs to be updated continuously. He...
Physiological Monitoring Systems for Fatigue Detection Within Firefighters: A B...
Pratas, P; Bustos, D; Guedes, J. C.; Joaquim Mendes; João Santos Baptista; Vaz, MFirefighters fatigue can negatively impact safety, production, and health. During firefighting, the risks are extreme, and firefighters health status is commonly neglected. A wearable sensor capable of predicting fatigue levels would have a substantial positive impact on the health and organisation of the teams. This review aims to collect information regards usage conditions and the development of wearable sen...
A Short Review on the Usage of Online Surveys Among Health Professionals
Bustos, D; Teixeira, T; Guedes, J. C.; João Santos Baptista; Vaz, MBackground: Surveys are an established tool within health services, allowing to recruit large and diverse cross-sections of the population and offer rapid data collection and cost-effectiveness. Various methods for conducting surveys exist, being the web-based method the one with increasing applicability. Despite its advantages, specific concerns might affect their validity and, therefore, require special atten...
Assessment of Fatigue Based on Workload and Rest Activity CyclesA Pilot Study
Stradioto Neto, EA; Bustos, D; Guedes, J. C.Fatigue is defined as an unpleasant symptom surrounded by sensations that vary from tiredness to exhaustion. There are several careers that demand much effort from their workers, inducing fatigue and affecting their health and performance. The goal of this paper is to establish a series of alerts to anticipate the level of fatigue an individual exposed to emergency situations may experience. In order to do this...
Medium and Long-Term Assessment of Fatigue Based on Workload and Rest-Activity ...
Stradioto Neto, EA; Bustos, D; Guedes, J. C.Fatigue is considered an intermediate state between tiredness and exhaustion. This study aims to filter and evaluate a series of articles focused on fatigue associated with activities performed in long working hours, seeking to understand better the causes, equipment, and methods used to assess this condition. For this purpose, a bibliographic review of the literature was performed using the systematic review m...
Cortisol as a Biomarker of Work-Related Stress in Firefighters: A Systematic Re...
Teixeira, T; Santos Baptista, J; Bustos, D; Guedes, J. C.Introduction: Work-related stress results from exposure to factors such as high workloads and lack of control over ones work. This exposure stimulates the hypothalamic-pituitary-adrenal axis to increase the secretion of stress-related glucocorticoid hormones, including cortisol. The main objective of this study was to investigate the production of cortisol (or cortisol levels) of firefighters in response to wor...
Fatigue detection through physiological assessment during real-life occupationa...
Bustos, D; Guedes, J. C.; Pratas, P; Vaz, M; Costa, JT; Fernandes, R; João Santos Baptista<jats:p>Background: Fatigue is a significant health and safety-related problem among workers. In general, it decreases performance and physical strength, causing incidents and accidents in operational situations. During military activities, soldiers often encounter severe conditions, which combined lead to fatigue manifestations affecting their health and performance. Continuous monitoring of their overall heal...
