Abstract(s)
Os teatros de operações da atualidade estão constantemente a ser moldados pela evolução de tecnologias, armamento e táticas militares. O combate Nuclear, Biológico, Químico e Radiológico é um assunto bastante sensível devido à sua capacidade devastadora de causar destruição e a perda de vidas em massa.
O presente trabalho de investigação, possui como principal objetivo validar um protocolo físico mediante o controlo dos parâmetros fisiológicos, numa amostra equipada com o equipamento de proteção individual. A vertente experimental do trabalho baseia-se em analisar a variação dos parâmetros fisiológicos e a perceção subjetiva de indicadores de tolerância ao calor durante a realização de um protocolo físico em ambientes com duas temperaturas diferentes, a 18 ºC e a 27ºC. Com isto pretendeu-se verificar se o protocolo realizado permite avaliar e retirar pareceres sobre a tolerância ao calor nos militares que utilizam o equipamento de proteção individual.
Como suporte para esta investigação, foi realizado um estudo com base em documentos oficiais publicados de várias instituições e organizações e ainda de vários artigos e revistas científicas para justificar e complementar o resultado dos testes dos protocolos realizados.
Apurou-se através da análise dos resultados obtidos e da revisão de literatura que em relação à variação da temperatura interna, temperatura da pele, frequência cardíaca e da perceção de stress térmico durante a realização do protocolo físico, que estes tendem a aumentar no desenrolar do protocolo tanto a 18ºC como a 27ºC. Por outro lado, concluiu-se também que a utilização do equipamento de proteção individual em ambientes mais quentes provoca um maior aumento do índice de tensão fisiológica e uma perceção de conforto térmico inferior.
Por fim, a implementação deste protocolo no exército português como teste de avaliação física ou como teste de admissão para os elementos que pretendem integrar a equipa Nuclear, Biológica, Química e Radiológica é uma mais-valia na medida que apesar de não exigir uma demanda física muito intensa, consegue avaliar a tolerância ao calor com o equipamento de proteção individual.
The current theaters of operations are constantly being shaped by the evolution of technologies, weaponry, and military tactics. Nuclear, Biological, Chemical, and Radiological combat is a very sensitive subject due to its devastating capacity to cause destruction and mass loss of life. The main objective of this research is to validate a physical protocol by controlling physiological parameters in a sample equipped with an individual protective equipment. The study aims to analyze the variation of physiological parameters and the subjective perception of thermal stress indicators during the execution of a physical protocol in environments with two different temperatures, 18ºC and 27ºC, and to verify whether the conducted protocol allows for the evaluation and assessment of heat tolerance in military personnel using individual protective equipment. As a basis for this investigation, research was conducted based on official documents published by various institutions and organizations, as well as articles and scientific journals, to justify and complement the results of the tests conducted on the protocols. It was determined through the analysis of the obtained results and the literature review that, regarding the variation of internal temperature, skin temperature, heart rate, and perception of thermal stress during the execution of the physical protocol, these tend to increase as the protocol progresses at both 18ºC and 27ºC. On the other hand, it was also concluded that the use of individual protective equipment in warmer environments causes a higher index of physiological strain and a lower perception of thermal comfort. Finally, the implementation of this protocol in the Portuguese Army, either as a physical evaluation test or as an admission test for those wishing to join the Nuclear, Biological, Chemical, and Radiological team, is an added value. Although it does not demand very intense physical exertion, it manages to evaluate heat tolerance with the individual protective equipment.
