Our aim was to evaluate musculoskeletal discomfort and the lifestyle of military police officers of administrative and tactical force departments. Military police officers were distributed into two groups: administrative (Adm, n = 15) and tactical force (TF, n = 16) departments. Their lifestyle was assessed using the Fantastic Lifestyle questionnaire. Moreover, physical activity quantification was assessed using the International Physical Activity questionnaire, and musculoskeletal discomfort was quantified using the Corlett diagram. The mean total time of physical activity was 546 ± 276 min per week. No differences (p = 0.0832) were found between the Adm (454 ± 217 min) and TF (623 ± 301 min) groups. Concerning lifestyle, in general the sample presented very good (42%) and good (42%) style classification. For this parameter, no significant differences were found, but only a tendency was discovered (x²: 7.437; p = 0.0592); indeed, the TF presented a better classification (63%) of very good, compared to the Adm (53%) of good. No differences (p > 0.05) were found in musculoskeletal perception of discomfort between the right and left sides (p > 0.05) for all police officers and between the Adm and FT groups (p > 0.05). Military police officers showed high and moderate risk for waist circumference and waist-to-hip ratio, respectively; however, lifestyle and total time of physical activity were considered adequate without differences between military administrative and tactical force sectors.

Introdução: a análise do sono de militares ainda é pouco compreendida, principalmente pelas características das atividades laborais dos agentes de segurança pública pertencentes a grupos de operações especiais. Objetivo: o objetivo deste estudo foi avaliar e associar indicadores antropométricos, nível de atividade física e horas de sono de policiais militares da Companhia de Operações de Choque do Batalhão de Missões Especiais do Espírito Santo (BME-ES). Métodos: 61 policiais militares foram distribuídos em dois grupos de acordo com o número de horas de sono, sendo suficiente (S, n:20) e insuficiente (I, n:41). Foram avaliados percepção geral de saúde, indicadores ocupacionais e tempo de atividade física semanal. Resultados: Não foram encontradas diferenças na idade e no tempo de serviço entre os militares. O número de horas de sono diferiu (p<0,001) entre os grupos I (5,46±0,9) e S (7,70±0,4). Foram encontradas diferenças significativas (p<0,05) entre os grupos na massa corporal, IMC, % de gordura, massa gorda e circunferência da cintura, mas não na massa magra e atividade física. Correlação negativa fraca entre horas de sono e percentual de gordura e massa gorda. Conclusão: a maioria dos militares apresentou boa percepção geral dos indicadores de saúde, com alta prevalência de atividade física mesmo com excesso de peso e distribuição moderada de gordura corporal.

Introduction: The lifestyle of military personnel can increase the risk of disease. Lifestyle can be considered a way of life involving values, choices, daily practices, forms of consumption, leisure habits, work, religion and socializing, expressing the characteristics of an individual or group, and can increase the risk of disease in military officers. Objective: This study aimed to compare the lifestyles of military police soldiers and corporals in the municipality of Vitória-ES. Materials and methods: 29 military police officers, 14 soldiers, and 15 corporals, had their lifestyles assessed using the Fantastic Lifestyle questionnaire, which included family and friends, physical activity, nutrition, smoking and drugs, alcohol, sleep, seat belts, stress, safe sex, type of behavior, introspection and work. Sleep quality was also assessed, by the Pittsburgh Sleep Quality Scale involving sleep factors such as subjective quality, latency, duration, habitual efficiency, disorders, use of sleep medication, and daytime dysfunction, as well as the classification of poor sleep quality, sleep disorders, and quality. Results: Corporals were found to have higher body mass (p= 0.012), BMI (p= 0.039), and length of service (p= 0.001). As for lifestyle, there was a difference (p= 0.025) in nutrition, with 43% of the soldiers being very good and 60% of the corporals being good. In terms of sleep quality, 60% of the soldiers had poor sleep quality and 40% of the corporals had some kind of sleep disorder. Conclusion: Corporals had higher body mass, BMI, and sleep disorders, while soldiers had poor sleep quality.

Introdução: O estilo de vida de militares pode aumentar o risco de doenças. O estilo de vida (EV) pode ser considerado a maneira de viver envolvendo valores, escolhas, práticas cotidianas, as formas de consumo, os hábitos de lazer, o trabalho, a religião e o convívio em sociedade, expressando as características de um indivíduo ou da coletividade, podendo aumentar o risco de doenças em militares. Objetivo: comparar o estilo de vida de soldados e cabos da polícia militar no município de Vitória-ES. Materiais e métodos: 29 policiais militares, sendo 14 soldados e 15 cabos tiveram seu Estilo de Vida avaliado pelo questionário Fantastic Lifestyle englobando família e amigos, atividade física, nutrição, cigarro e drogas, álcool, sono, cinto de segurança, estresse, sexo seguro, tipo de comportamento, introspecção e trabalho. Também foi avaliada a qualidade do sono, pela escala de qualidade do sono de Pittsburgh envolvendo fatores do sono como a qualidade subjetiva, latência, duração, eficiência habitual, transtornos, uso de medicamentos para dormir, disfunção diurna, além da classificação de má qualidade do sono, distúrbios do sono e qualidade. Resultados: Observou-se que cabos possuem maior massa corporal (p= 0,012), IMC (p= 0,039) e tempo de corporação (p= 0,001). Quanto ao estilo de vida, houve diferença (p= 0,025) na nutrição com 43%, entre os soldados foi muito bom e 60% dos cabos foi bom. Na qualidade do sono, 60% dos soldados foi constatada uma má qualidade e em 40% dos cabos observou-se algum distúrbio de sono. Conclusão: Os cabos apresentaram maior massa corporal, IMC, e distúrbios de sono, enquanto soldados apresentaram má qualidade de sono.

Introduction: resistance training (RT) can elicit acute cardiovascular changes influenced by exercise selection, particularly regarding joint involvement and muscle mass recruitment. Whether previous RT experience modifies hemodynamic responses during single- and multi-joint resistance exercises remains unclear. Objective: to investigate whether previous RT experience alters acute hemodynamic responses to single- and multi-joint resistance exercises. Methods: twenty-four healthy men were allocated into trained (T; ≥12 months of RT experience) and untrained (UT) groups. Participants performed two RT sessions consisting of single-joint [extension chair (EC)] and multi-joint [leg press (LP)] exercises at 75% of 1-RM, with four sets of 12 repetitions and 1-minute rest intervals. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart pressure product (HPP) were assessed before and after exercise. Repeated-measures ANOVA with Bonferroni post hoc correction was applied, and effect sizes were calculated using partial eta squared (ηp²). Results: significant differences were observed in 1-RM performance between groups for both EC (T: 110 ± 26 kg vs. UT: 75 ± 20 kg; p<0.001) and LP (T: 240 ± 54 kg vs. UT: 150 ± 37 kg; p0.05). However, significant time effects were observed for HR, SBP, DBP, and HPP after exercise in both groups (p<0.05; ηp² ranging from 0.90 to 0.95, indicating large effects). Multi-joint exercise (LP) was associated with greater increases in SBP, DBP, and HPP compared with single-joint exercise (EC), regardless of training status. Conclusion: multi-joint resistance exercise was associated with greater acute hemodynamic responses compared with single-joint exercise, regardless of previous RT experience. These findings suggest that exercise selection may exert greater influence on acute cardiovascular responses than training status.
