Validação do questionário de saúde e performance para policiais e bombeiros militares (QSPM) / Validation of health and performance questionnaire for military police and firefighter (QSPM) / Validation of health and performance questionnaire for military police and firefighter (QSPM)

O objetivo deste estudo foi desenvolver e analisar a validade de conteúdo, constructo e a fidedigni-dade de um questionário para avaliar a demanda física e operacional, saúde e condições de trabalho em policiais e bombeiros militares. O Questionário de Saúde e Performance para Militares (QSPM) foi desenvolvido por pesquisadores militares e não militares, a validade foi analisada com o índice de validade de conteúdo (IVC), análise fatorial exploratória e a fidedignidade com o percentual de concordância (%C), coeficiente Kappa e alfa de Cronbach. Nove juízes participaram da validação de conteúdo, 732 militares (15% mulheres) participaram da etapa de validação de constructo e 262 militares (18% mulheres) responderam duas vezes ao QSPM para a verificação da fidedignidade. As análises foram realizadas no software SPSS 26 e o nível de significância mantido em 5%. O QSPM apresentou o IVC de 0,98 e variância total explicada em 54,7%. A reprodutibilidade apresentou valores de %C entre 97,2 - 100,0%, Kappa entre 0,94 - 1,00 (p < 0,05) e alpha de Cronbach entre 0,80 - 1,00 (p < 0,05). Conclui-se que o QSPM apresentou validade de conteúdo, constructo e fidedignidade para avaliar a frequência da demanda física e operacional, as condições de saúde e de trabalho de policiais e bombeiros militares

The aim of this study was to develop and analyze the content and construct validity and reliability of a questionnaire to assess the performance, health and working conditions of police officers and military fire-fighters (QSPM). Civilian and military personnel carried out the development of the QSPM. The validity was analyzed by the content validity index (CVI), factor analysis, and the reproducibility by the simple agreement (%SA), the Kappa coefficient, and Cronbach's alpha. Nine experts participated in the content validation, 732 military personnel (15 women) participated in the construct validation, and 262 military (18% women) answered the QSPM twice to measure reproducibility. The QSPM had a CVI of 0.98. In the exploratory factorial analysis, when considering four factors, and the total explained variance was 54.7%. The reproducibility showed %SA values varying between 97.2 to 100.0%, Kappa values varying between 0.94 to 1.00 (p < 0.05 for all questions) and, Cronbach's α values varying between 0.80 to 1.00 (p < 0.05 for all questions). In conclusion, the QSPM showed content validity, construct validity and reliability to measure the frequency of physical-operational demand, the presence of morbidities, and the working condi-tions of police officers and firefighters

Physical fitness test performance probability with increasing age: suggestions for practical applications in military physical training / Probabilidade de desempenho no teste de aptidão física e o aumento da idade: sugestões de aplicações práticas no treinamento físico militar

Abstract This article analyzes the Physical Fitness Test (PFT) which is performed by the Brazilian Navy to check the physical parameters of its military members in order to present the performance of probabilities with increasing age. We analyzed 702 PFT data in this study, separated into three groups based on the age of those assessed by the PFT, as follows: young adults (YA, n=91, age range between 20-30 years), adults (A, n=243, age range between 30-40 years) and mature adults (MA, n=368, age range between 40-50 years old). PFT measurements were: Body Mass Index (BMI), 100 m freestyle swimming, 3,200 m running, 1 min sit-ups, Pull-up on the bar and Push-up test. The main results indicated significant differences between groups when compared Body mass (YA: 79.1±11.4kg and A: 82.1±14kg < MA: 84.1±12.3kg), BMI (YA: 25.4±2.9 < A: 26.4±4.3 < MA: 27.5±4),Pull-ups (YA: 10.8±4.6 freq./min < A: 10±3.6 freq./min < MA: 8.5±4.7 freq./min), 3,200 m running time (YA: 1282,1±172,4s < A: 1421±199.8s < MA: 1566.7±192.4s) and 100 m swimming time (YA: 140.1±45.6s < A: 149.7±37.9s < MA: 180.8±50s) and the regression analysis demonstrated that 3,200 m running and pull-ups were the most affected variable of aging process (p<0.05). In summary, it is possible to carry out a practical application, considering aging process and the decline of the aerobic capacity and the upper limbs strength-power in Military Physical Training.

Resumo Este artigo analisou o Teste de Aptidão Física (PFT), realizado pela Marinha do Brasil para medir os parâmetros físicos de seus militares, a fim de apresentar as probabilidades de desempenho com o aumento da idade. Analisamos 702 dados de PFT, separados em três grupos com base na idade, como segue: adultos jovens (YA, n=91, faixa etária entre 20-30 anos), adultos (A, n=243, faixa etária entre 30-40 anos) e adultos de meia idade (MA, n=368, faixa etária entre 40-50 anos). As medidas da PFT foram: Índice de Massa Corporal (BMI), natação de 100m livre, 3.200m de corrida, 1min de abdominais, flexão na barra e flexão de braço. Os principais resultados indicaram diferenças significativas entre os grupos quando comparados a massa corporal (YA: 79,1±11,4kg e A: 82,1±14kg <MA: 84,1±12,3kg), IMC (IA: 25,4±2,9 <A: 26,4±4,3 <MA: 27,5±4,0), Pull-ups (YA: 10,8±4,6 freq./min <A: 10,0±3,6 freq./min <MA: 8,5±4,7 freq./min), 3.200 m de tempo de execução (YA: 1282,1±172,4s <A: 1421±199,8s <MA: 1566,7±192,4s) e 100m de natação (YA: 140,1±45,6s <A: 149,7±37,9s <MA: 180,8±50s) e a análise de regressão demonstrou que 3.200m de corrida e flexões de braço foram a variável mais afetada do processo de envelhecimento (p<0,05). Em resumo, é possível realizar uma aplicação prática, considerando o processo de envelhecimento e o declínio da capacidade aeróbica e da força-força dos membros superiores no treinamento físico militar.

Research and application of disruptive technology identification methods / 军事医学

Though increasing attention is paid to the disruptive technology due to its characteristic, there are so many flaws with the mainstream identification methods for disruptive technology and there is no consensus among experts.By com-bining the findings of the research institutions both at home and abroad and their identification methods,and using such methods as literature and specialist consultation,the types of identification methods,differences in the research institutions of disruptive technology, future development direction and problems of the identification methods are analyzed.Some suggestions on the research of disruptive technology in China are raised for the next step.

Concept research of Zhishengquan / 军事医学

To update and improve the Chinese concept of Zhishengquan,a comparative analysis was made of the U.S. military terms and PLA military terms.Zhishengquan is re-defined as "command and superiority in the bio-domain".
