Good decision-making is associated with an adaptive cardiovascular response to social competitive stress.
2018
Competition elicits different psychological and cardiovascular responses depending on a person's skills. Decision-making has been considered a distal factor that influences competition, but there are no studies analyzing this relationship. Our objective was to analyze whether decision-making affects the response to competition. Specifically, we aimed to test whether good performers on a decision-making test, the Iowa Gambling Task (IGT), showed an adaptive cardiovascular response to competition. In all, 116 participants (44 women) performed the IGT and were classified into Good or Poor decision-makers. Subsequently, they were exposed to a stress task in two different conditions: a face-to-f…

The cardinal exercise stopper: Muscle fatigue, muscle pain or perception of effort?
2018
The capacity to sustain high-intensity aerobic exercise is essential for endurance performance. Therefore, it is important to understand what is the factor limiting time to exhaustion (TTE) in healthy and fit adults. In Study 1, maximal voluntary cycling power (MVCP) was measured in 11 volunteers before and immediately after a high-intensity TTE test on cycle ergometer. Cadence was 60 rpm in both the MVCP and TTE tests. Despite a 35% loss in MVCP, power produced during the final MVCP test (mean ± SD 469 ± 111 W) was significantly higher than the power required by the TTE test (269 ± 55 W) (P < 0.001). In Study 2, 12 participants performed a cold pressor test (CPT) to the limit of tolerance …
Foot Temperature Assessment
2016
Thermographic studies of the foot can be very useful in 3 different ways: in preventing injury, in analyzing sporting technique and in assessing the effects of footwear and clothing. The aim of this chapter is to discuss several methodological points concerning the thermal analysis of the foot using infrared thermography, as well as to discuss how it can be applied to the science of sports, both in areas already researched and those as yet uninvestigated.
A survey on the thermal conditions experienced by a surgical team
2007
The complex environment of the operating theatre is shared by a group of people having highly different needs: on one side, there is a surgical team whose work may last many hours and, on the other, an anaesthetized patient often subject to liquid infusion. Up to now, little consideration has been given to the different needs of the surgical team who may be affected according to their positions with respect to the scialytic lamp and their particular task. Clothing influences the comfort of the surgical team to a considerable degree: in fact, in some surgery (orthopaedics, neurosurgery and so on), surgeons and assistants must wear paper overalls beneath non-breathable plastic overalls and p…
Towards real-time detection of cognitive effort in driving: Contribution of cardiac measurement
2016
En 2013, on estime que 40 à 50% des accidents corporels seraient dus à des défauts d'attention de la part du conducteur. Des études récentes ont mis en évidence la possibilité de détecter des états attentionnels dégradés afin de pouvoir mieux assister le conducteur ; ce thème de recherche représente donc un nouveau gisement de sécurité routière. Cette étude se concentre sur la détection de l'effort cognitif fournit par les conducteurs et cherche, par l'étude de la variation du rythme cardiaque, à identifier un indicateur d'effort sensible sur de courtes fenêtres temporelles.Chacun des 18 participants a passé 8 conditions expérimentales sur simulateur de conduite : la moitié où seule une tâc…
Stereoscopic Viewing Enhances Visually Induced Motion Sickness but Sound Does Not
2012
Optic flow in visual displays or virtual environments often induces motion sickness (MS). We conducted two studies to analyze the effects of stereopsis, background sound, and realism (video vs. simulation) on the severity of MS and related feelings of immersion and vection. In Experiment 1, 79 participants watched either a 15-min-long video clip taken during a real roller coaster ride, or a precise simulation of the same ride. Additionally, half of the participants watched the movie in 2D, and the other half in 3D. MS was measured using the Simulator Sickness Questionnaire (SSQ) and the Fast Motion Sickness Scale (FMS). Results showed a significant interaction for both variables, indicatin…
Real-Time Breath Analysis in Type 2 Diabetes Patients During Cognitive Effort
2013
The understanding the functional expression of exhaled volatile organic compounds (VOCs) has gradually expanded from the initial identification of breath pathological markers to direct expression of physiological activity. In the present study we investigated the potential application of breath analysis in real-time monitoring of type 2 diabetes mellitus (T2DM) patients versus control subjects while performing a cognitive task. T2DM is associated with cognitive impairment and neural deficits, because of insulin resistance and high expression of insulin receptors in the hippocampus. We set out to seek the evidence for mutual associations among breath exhale, on the one side, and T2DM and cog…
Advanced Endoscopic Imaging Methods
2021
Endoscopic imaging is the mainstay of gastrointestinal endoscopy and has experienced remarkable improvements in recent decades. Further endoscopic innovations stemming from major technological advances such as artificial intelligence and deep learning are at advanced stages of development and will be increasingly deployed in routine clinical practice. These will improve the detection and enable real-time optical diagnosis of pathologies in the gastrointestinal tract. Furthermore, the utilization of endoscopic robots may result in higher diagnostic yield and greater patient comfort. This chapter covers the most recent developments around computer-assisted diagnosis, hypoxia and three-dimensi…
