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 health status would  prevent  its  adverse  effects.  Objective:  This  work  aimed  to  present  the  preliminary  results  of  a retrospective assessment of military training physiological recordings using an alert-based fatigue detection algorithm  to  validate  its  accurate  functioning.  Methods:  Three  case  studies  from  soldiers  participating  in military  training  tests  were  recruited  for  evaluation.  The  referred  algorithm  was  developed  to  manage fatigue through the combined assessment of physiological variables and determine different fatigue levels warnings to advisetimely interventions and prevent potential health impact. Each examined case included the  continuous  recording  of  heart  rate,  breathing  rate  and  core  temperature.  The  algorithm  translated physiological  sensory  data  into  minute  alarms  according  to  fatigue levels  determined  through  the conjunction of normative and related research criteria. Results and Discussion: Outcomes revealed that the algorithm  could  evidence  the  different  stages  of  training  and  the  resulting  physical  demands  on  soldiers using  their  physiological  response  throughout  the  exercises.  Retrieved  fatigue  alarms  showed  the  high physiological cost of military practices and helped to overview the impact of each training period. Finally, results  also  demonstrated  the  importance  of  individual  and contextualised  assessment  for  accurately characterise the subject's fatigue status. Conclusions: It is concluded that the developed decision model can improve  the  management  of  real-time  fatigue,  allowing  early  detection  of  potential  indicators  of  further physical impairments. Furthermore, it can lead to the enhancement of work-rest cycles, not only for tactical personnel but also  for any safety-sensitive  occupation. For future work, its validity will be tested through more participants, and other variableswill be added to improve its accuracy.<\/jats:p>","DOI":"10.24840\/978-972-752-279-8_0049-0055","type":"proceedings-article","created":{"date-parts":[[2021,8,31]],"date-time":"2021-08-31T16:31:34Z","timestamp":1630427494000},"page":"49-55","source":"Crossref","is-referenced-by-count":0,"title":["Fatigue detection through physiological assessment during real-life occupational situations: Preliminary results"],"prefix":"10.24840","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4942-7625","authenticated-orcid":false,"given":"D.","family":"Bustos","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2367-2187","authenticated-orcid":false,"given":"J.C.","family":"Guedes","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3380-5027","authenticated-orcid":false,"given":"P.","family":"Pratas","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6347-9608","authenticated-orcid":false,"given":"M.P.","family":"Vaz","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3947-8688","authenticated-orcid":false,"given":"J.C.
