A pilot study on energy expenditure estimation through decision modelling
D. Bustos; A. P. Sposito; A. D. Lucena; Joana GuedesThe generation of standardized equations for predicting energy expenditure, to be applied to every healthy individual, is still subject to research. The purpose of this study was to contribute to the development of a decision algorithm to estimate energy expenditure for its application over a wide range of physical activities. Ten participants (age 31.70 ± 4.19) performed a sequence of 12 activities chosen to r...
Perceção da qualidade da iluminação e sintomas associados
Ana Dias; Joana Guedes: Elaborate a tool that would allow to identify situations that are inadequate in relation to the illuminance conditions in the workplace, providing a more targeted intervention. In particular, the main objective of this study was to integrate a quantitative evaluation with a qualitative subjective assessment that would allow a more holistic approach on how the lighting conditions in working environment are per...
Real time fatigue assessment: Identification and continuous tracing of fatigue ...
Bustos, D; Joana Guedes; Alvares, M; João Santos Baptista; Vaz, M; Torres Costa, JCFatigue decreases performance and physical strength causing incidents and accidents in operational settings. An algorithm has been developed for the management of fatigue, in which assessment of monitored physiological parameters determines different categories of alert alarms with the aim of advising timely interventions and preventing further physical impairments. In this study, the performance of the algorit...
Influence of exposure to cold thermal environment on core and skin temperatures
J. Cardoso; J. Oliveira; T. Zlatar; D. Bustos; Joana Guedes; João Santos BaptistaExposure to extreme cold triggers in humans various of physiological responses, which is necessary to control is necessary when it comes to occupational exposure. The objective of the present study was to analyze the evolution of core temperature, mean skin temperature during exposure to extreme cold (-20 degrees C), with the usual protection for this type of exposure. From a total of 12 healthy individuals usi...

Joaquim Oliveira; João Cardoso; Tomi Zlatar; Lidia Denisse Bustos; Joana Guedes; João Santos BaptistaSevere cold exposure is a significant risk factor in the frozen food industry, influencing the health and safety of employees. The objective of this work is to verify the influence of the severe cold exposure, using personal protective equipment similar to those used in industry,on physiological parameters such as blood pressure, heart rate and core temperature. Twelve non-acclimatized male volunteers (mean ± S...

Real time fatigue assessment: A short review evidencing the usage of safety mon...
D. Bustos; Joana Guedes; R. S. Pinto; F. Conceicão; M. Vaz; J. C. Torres Costa; José Castela Costa; Mário Vaz; Filipe ConceiçãoFatigue decreases performance and physical strength causing incidents and accidents in operational settings. During military operations, soldiers encounter extreme conditions, which combined lead to a fatigue status that can cause serious physiological impairments, decreasing performance on the battlefield. Comprehensive studies in realistically stressful environments are essential to expand the knowledge regar...
Resposta Fisiológica e Atenção Seletiva em Bombeiros Recrutas: Estudo-Piloto
Joana Guedes; Joana Santos; Tatiana TeixeiraThe firefighting job highly exposes individuals, endangering their life's. The aim of this study was to evaluate the physical work load in three groups (n=34) of future firemen with different tasks simulated during the training, through the monitoring of the Heart Rate (HR). In addition, this study intended to understand the influence of the type of task performed in the selective attention and in the scale of ...
Influence of severe cold thermal environment on thermal sensation and physiolog...
Tomi Zlatar; J. Oliveira; J. Cardoso; D. Bustos; Joana Guedes; João Santos BaptistaExposure to cold affects health and poses significant risks for cardiovascular diseases, musculoskeletal complaints and symptoms. It is present in outdoor activities in high latitude environments and within different occupations, causing variations in core and skin body temperatures and affecting working performance, health and safety. This work aims to evaluate the changes in thermal sensation, and in some phy...
Real time fatigue assessment: A short review evidencing the relevance of physio...
Lidia Bustos; Joana Guedes; João Santos Baptista; Lucas Pereira; Mário Vaz; José C. Torres CostaFatigue decreases performance and physical strength causing incidents and accidents in operational settings. During military operations, soldiers encounter extreme situations, which combined lead to a fatigue status that can later develop in overreaching (OR) and overtraining (OT) conditions. Studies in real environments are essential to expand the knowledge regarding the consequences of stress exposure and fac...
