RESUMO

La composición corporal engloba una serie de variables relacionadas con la salud e influye en la condición física. A pesar de ello, existe poca evidencia sobre sus efectos en la capacidad operativa en militares. El objetivo de este estudio fue relacionar la composición corporal, la condición física y la capacidad operativa de militares chilenos. Participaron 57 militares chilenos (26,9 ± 4,8 años), con especialización operativa en infantería. La composición corporal fue evaluada con bioimpedancia octopolar estimando masa libre de grasa, tejido muscular y tejido adiposo, entre otras variables. También se realizaron las siguientes pruebas de condición física: 5000 m planos, dominadas, abdominales y flexibilidad, así como cuatro pruebas específicas de actividades operativas militares específicas (situación de combate simulado). Los resultados mostraron un porcentaje de tejido muscular de 45,4 ± 2,9 % (IC95%: 44,6 - 46,2), mientras que el porcentaje de tejido adiposo fue de 20,3 ± 4,9 % (IC95%: 14,7 - 17,3). Se encontraron correlaciones negativas de pequeña magnitud entre el tiempo de carrera (5000 m) y el tejido muscular (%) (r = -0,275) y positiva con el tejido adiposo (%) (r = 0,294). Sin embargo, se observaron correlaciones de alta magnitud entre dominadas y tejido muscular (%) (r = 0,517) y tejido adiposo (%) (r = -0,558). El tejido adiposo se relacionó negativamente con la capacidad aeróbica, fuerza de brazos(??) y fuerza resistencia abdominal, mientras que el tejido muscular se relacionó positivamente con estas mismas variables. No se apreciaron correlaciones entre la composición corporal y la capacidad operativa militar (p<0,05). Se concluye que la composición corporal y la condición física no se relacionan con la capacidad operativa militar en situación de combate en especialistas en infantería, pero si la composición corporal se relaciona con la fuerza y la capacidad cardiorrespiratoria.


SUMMARY: Body composition encompasses a series of variables that are health-related and influence physical condition. Nevertheless, there is little evidence on its effects on the operational capacity of the military. The objective of this study was to relate the body composition, the physical condition and the operational capacity of the Chilean military. Fifty-seven Chilean soldiers (26.9 ± 4.8 years) participated, with operational specialization in infantry. Body composition was evaluated with octopolar bioimpedance, estimating fat- free mass, muscle tissue, and adipose tissue, among other variables. The following physical condition tests were also carried out: 5000 m flat, pull-ups, abdominals and flexibility, as well as four specific tests of specific military operational activities (simulated combat situation). The results showed a percentage of muscle tissue of 45.4 ± 2.9 % (95%CI: 44.6 - 46.2), while the percentage of adipose tissue was 20.3 ± 4.9 % (95%CI). : 14.7-17.3). Negative correlations of small magnitude were found between race time (5000 m) and muscle tissue (%) (r = -0.275) and positive with adipose tissue (%) (r = 0.294). However, high magnitude correlations were observed between pull-ups and muscle tissue (%) (r = 0.517) and adipose tissue (%) (r = -0.558). Adipose tissue was negatively related to aerobic capacity, arm strength, and abdominal endurance strength, while muscle tissue was positively related to these same variables. No correlations were found between body composition and military operational capacity (p<0.05). It is concluded that body composition and physical condition are not related to military operational capacity in combat situations in infantry specialists, but body composition is related to strength and cardiorespiratory capacity.

Según la percepción subjetiva de sed al finalizar solo un 14% de los soldados no tenía sed. Conclusión: el estudio reflejó que el 64% de los soldados mantuvo una estrategia de reposición de líquidos óptima, dado que las pérdidas de peso se limitaron a lo esperable.


Abstract Introduction: exercising at high altitudes deserves special considerations when it comes to determining fluid requirements in athletes, especially in Army mountain troops. Maintaining a state of euhydration during physical activity is essential to avoid health complications. The aim of this research is to identify the hydration status of soldiers of the VIII Mountain Brigade of the Argentine Army based in Mendoza, Argentina in 2021. Materials and method: descriptive, observational, longitudinal study. The sample consisted of 87 male soldiers. The data collected included the amount and type of fluid intake, urinary specific gravity by using a manual refractometer, percentage of weight change and subjective perception of thirst. Statistical analysis for qualitative variables was done with the χ2 test and 95% CI, quantitative variables were compared using the t-Student test. Results: 96.5% of soldiers hydrated themselves with water. The mean fluid intake was 1.34±0.74 liters (L), with a maximum intake of 4 L and a minimum of 0.5 L. 36% percent of the sample presented a body weight loss of more than 2% at the end of the activity, the relative difference referred to the mean initial weight was 1.7±1.4%. At the end, 43% were classified as euhydrated and 29% as severely hypohydrated according to specific urinary gravity. According to the subjective perception of thirst at the end, only 14% of the soldiers were not thirsty. Conclusion: the study showed that 64% of the soldiers maintained an optimal fluid replacement strategy, given that weight losses were limited to what was expected.

RESUMO

SUMMARY: The results of numerous medical and kinesiological studies indicate the existence of differences in pulmonary function in relation to age, body height, and the relationship between certain parameters of body composition. The aim of this study was to determine the state of morphological characteristics and pulmonary function of naval saboteurs and ground Special Forces of the Armed Forces of Montenegro. The sample of participants included 30 naval saboteurs aged 30.3±6 years and 30 members of the ground special forces aged 25.6±5 years. The sample of measuring instruments included 4 indicators each for the evaluation of longitudinal dimensionality, transversal dimensionality, mass and body volume, subcutaneous fat, body composition, and pulmonary function. The central and dispersion parameters of the variables were calculated. The specificities of body composition of the naval saboteurs and members of the ground Special Forces of the AF of Montenegro were determined, while the parameters of lung volume and capacity and the parameters of airway flow indicated an excellent state of their respiratory function. Furthermore, it was determined that the studied members of the armed forces had no individual health risks in the sense of the onset of obesity or obstructive ventilatory defects. The results obtained indicate the need for further studies which would predominantly focus on the impact of individual morphological measurements and parameters of body composition on pulmonary function. This would provide important data both for the armed forces in the sense of improving the training system and the realization of specific tasks, as well as for kinesiology as a science from the aspect of determining certain regularities in the functioning of the human body in specific living and working conditions in the armed forces.


Los resultados de numerosos estudios médicos y kinesiológicos indican la existencia de diferencias en la función pulmonar en relación con la edad, la altura corporal y la relación entre determinados parámetros de la composición corporal. El objetivo de este estudio fue determinar el estado de las características morfológicas y la función pulmonar de los saboteadores navales y de las Fuerzas Especiales terrestres de las Fuerzas Armadas de Montenegro. La muestra de participantes incluyó a 30 saboteadores navales de 30,3±6 años de edad y 30 miembros de las fuerzas especiales terrestres de 25,6±5 años. La muestra de instrumentos de medición incluyó 4 indicadores cada uno para la evaluación de dimensionalidad longitudinal, dimensionalidad transversal, masa y volumen corporal, grasa subcutánea, composición corporal y función pulmonar. Se calcularon los parámetros centrales y de dispersión de las variables. Se determinaron las especificidades de la composición corporal de los saboteadores navales y miembros de las Fuerzas Especiales terrestres de la FA de Montenegro, mientras que los parámetros de volumen y capacidad pulmonar y los parámetros de flujo de las vías respiratorias indicaron un excelente estado de su función respiratoria. Además, se determinó que los miembros de las fuerzas armadas estudiados no tenían riesgos individuales de salud en el sentido de la obesidad o defectos ventilatorios obstructivos. Los resultados obtenidos indican la necesidad de más estudios que se centren predominantemente en el impacto de las medidas morfológicas individuales y los parámetros de composición corporal en la función pulmonar. Esto proporcionaría datos importantes tanto para las fuerzas armadas en el sentido de mejorar el sistema de entrenamiento y la realización de tareas específicas, como para la kinesiología como ciencia desde el aspecto de determinar ciertas regularidades en el funcionamiento del cuerpo humano en situaciones específicas de vida. y condiciones de trabajo en las fuerzas armadas.

RESUMO

Soldiers in active military service need optimal physical fitness for successfully carrying out their operations. Therefore, their health status is regularly checked by army doctors. These inspections include physical parameters such as the body-mass index (BMI), functional tests, and biochemical studies. If a medical exam reveals an individual's excess weight, further examinations are made, and corrective actions for weight lowering are initiated. The collection of urine is non-invasive and therefore attractive for frequent metabolic screening. We compared the chemical profiles of urinary samples of 146 normal weight, excess weight, and obese soldiers of the Mexican Army, using untargeted metabolomics with liquid chromatography coupled to high-resolution mass spectrometry (LC-MS). In combination with data mining, statistical and metabolic pathway analyses suggest increased S-adenosyl-L-methionine (SAM) levels and changes of amino acid metabolites as important variables for overfeeding. We will use these potential biomarkers for the ongoing metabolic monitoring of soldiers in active service. In addition, after validation of our results, we will develop biochemical screening tests that are also suitable for civil applications.

RESUMO

RESUMEN: La Bioimpedancia Eléctrica (BIA), al ser una técnica no invasiva pero de elevada precisión, se ha convertido en la actualidad en una herramienta valiosa para determinar la composición corporal en militares, facilitado el control de las distintas variables que se asocian a cada especialidad. El objetivo del presente estudio fue describir el perfil de composición corporal en militares de elite al momento de finalizar un curso de especialización. Participaron 11 militares con un rango de edad entre 22 y 29 años. Se evalúo la composición corporal a través de BIA, inmediatamente después de finalizado un curso de especialización para militares de élite. Las evaluaciones en los militares sobre las variables de la composición corporal a través de BIA mostraron: peso corporal de 84,3 ± 4,52 kg, talla 1,78 ± 0,06 m, índice de masa corporal (IMC) 26,5 ± 1,09, tejido adiposo de 13,7 ± 3,65 %, tejido muscular 49,5 ± 2,34 %, masa libre de grasa 72,7 ± 5,23 kg y 53,2 ± 3,78 l de agua corporal total. Conclusiones: Los militares de elite presentaron elevados niveles de masa libre de grasa, tejido muscular y bajos niveles de tejido adiposo lo que favorece el desarrollo de las actividades militares especializadas y disminuye el riesgo de lesiones. Los datos aquí recogidos sirven como marco de referencia para futuros estudios.


SUMMARY: Electrical bioimpedance (BIA), being a non- invasive technique but with high precision, has become a valuable tool for determining body composition in the military, facilitating the control of the different variables associated with each specialty. The aim of the present study was to describe the body composition profile of elite military personnel at the end of a specialization course. Eleven military personnel between 22 and 29 years of age participated in the study. Body composition was assessed by BIA immediately after completion of a specialization course for elite military personnel. Assessments in the military on body composition variables through BIA showed: body weight of 84.3 ± 4.52 kg, height 1.78 ± 0.06 m, body mass index (BMI) 26.5 ± 1.09, adipose tissue of 13.7 ± 3.65 %, muscle tissue 49.5 ± 2.34 %, fat free mass 72.7 ± 5.23 kg and 53.2 ± 3.78 l of total body water. Conclusions: Elite military personnel presented high levels of fat free mass, muscle tissue and low levels of adipose tissue which favors the development of specialized military activities and decreases the risk of injury. The data collected here serve as a frame of reference for future studies.

RESUMO

SUMMARY: Anatomic variations in hip joint are one of the risk factors for the occurrence of osteoarthritis of that part of locomotor system. Due to different age structure and a special way of conducting physical activity in the army, it is justified to presume the presence of even other risk factors which relate to the aging process, carrying of oversize weight and performing higher amplitudes of movement under load. The objective of the study related to determining the existence of eventual anatomic variations in the hip joint in soldiers of different age. This cross-sectional study covers 240 soldiers of Montenegro Army, divided into 8 age groups. Gathered data for morphological measures hip width and hip circumference were processed using the basic statistics, multivariate and univariate of variance and Tukey's Honestly Significant Difference test-HSD. The differences were considered statistically significant for p≤0.05. It was determined that for both morphological measures there are differences between soldiers of certain age. This is confirmed also by drastic deviations between certain age groups obtained for the defined level of statistical significance. The most pronounced is the detection of the annual increase of hip width of soldiers which is higher for 0.38 mm compared to general population. Based on the obtained results the existence of anatomic variations in soldiers' hip joints is stated. The confirmed anatomic changes in conjunction with other risk factors may lead to hip osteoarthritis, i.e to soldiers' health condition impairment. It is necessary to conduct longitudinal studies on the same examinees with precise diagnostics.


RESUMEN: Las variaciones anatómicas en la articulación coxal son uno de los factores de riesgo de la osteoartritis de esa zona del sistema locomotor. Debido a la diferente estructura respecto a la de edad y una forma especial de realizar la actividad física en el ejército, se justifica presumir la presencia de otros factores de riesgo que se relacionan con el proceso de envejecimiento, el transporte de peso sobredimensionado y la realización de mayores amplitudes de movimiento bajo carga. El objetivo del estudio fue determinar la existencia de eventuales variaciones anatómicas en la articulación coxal en soldados de diferentes edades. Este estudio transversal incluyó 240 soldados del Ejército de Montenegro, divididos en 8 grupos de edad. Los datos recopilados para las medidas morfológicas del ancho y la circunferencia de la articulación coxal se procesaron utilizando las estadísticas básicas, la varianza multivariada y univariada y la prueba HSD de diferencia significativa de Tukey. Las diferencias fueron consideradas estadísticamente significativas para p≤0,05. Se determinó que para ambas medidas morfológicas existen diferencias entre soldados de cierta edad. Esto fue confirmado también por las desviaciones drásticas entre ciertos grupos de edad obtenidos para el nivel definido de significación estadística. El más pronunciado es la detección del aumento anual del ancho de cadera de los soldados, que es superior en 0,38 mm en comparación con la población general. En base a los resultados obtenidos se afirma la existencia de variaciones anatómicas en las articulaciones coxales de los soldados. Los cambios anatómicos confirmados junto con otros factores de riesgo pueden conducir a la osteoartritis de cadera, es decir, al deterioro del estado de salud de los soldados. Es necesario realizar estudios longitudinales en los mismos examinados con diagnósticos precisos.

RESUMO

Mules are essential for pack work in mountainous areas, but there is a lack of research on this species. This study intends to assess the perceptions, attitudes, empathy and pain perception of soldiers about mules, to understand the type of human-mule relationship. For this, a survey was applied with closed-ended questions where the empathy and pain perception tools were included and later analyzed through correlations. Open-ended questions were analyzed through text mining. A total of 73 soldiers were surveyed. They had a wide range of ages and years of experience working with equids. Significant positive correlations were found between human empathy, animal empathy and pain perception. Soldiers show a preference for working with mules over donkeys and horses. Text mining analysis shows three clusters associated with the mules' nutritional, environmental and health needs. In the same line, relevant relations were found for the word "attention" with "load", "food", and "harness". When asked what mules signify for them, two clusters were found, associated with mules' working capacity and their role in the army. Relevant relations were found between the terms "mountain", "support", and "logistics", and also between "intelligent" and "noble". To secure mules' behavioral and emotional needs, future training strategies should include behavior and welfare concepts.

RESUMO

The composition of chemical weaponry of termite soldiers show interspecific and intraspecific variation. However, spatial effects on the qualitative and quantitative compositions of these substances in Neotropical termites are poorly known. Hexane extracts of heads and the defensive secretion of soldiers of Constrictotermes cyphergaster from four localities in Northeast Brazil were analyzed by gas chromatography and mass spectrometry. Chemical analysis allowed the detection of 54 compounds from the head extract and from the direct extraction of the defensive secretion of soldiers, and the percentage of common substances and the presence of exclusive substances varied depending on the spatial distance between colonies. The profile of the chemical armament of soldiers consists basically of terpenoids: monoterpenes (45.53%-71.97 - for head extract and 57.41% - 78.56 for secretion) and sesquiterpenes (19.69% - 35.78% for head extract and 18.41% - 33.31%for secretion). In general, the main component of the chemical arsenal, regardless of the methodology used for extraction, was α-pinene (27.98-50.44%). Two chemotypes were identified based on chemical differences between populations of ecoregions with distinct spatial-environmental and climate characteristics: (1) α-pinene <33%; (2) α-pinene >33% for both extracts (head and secretion). The results reveal a similar pattern of chemical differentiation for soldiers in both extracts (head and secretion), with increasing differences as a function of distance between the analyzed colonies.

RESUMO

The performance of eusocial insect colonies is optimized by the division of labor among castes. Throughout the evolution of termites, there was an evident increase in the proportion of soldiers in the colonies. In derived termite species, the soldiers have a crucial role in defense and the initial phases of foraging. Here, we evaluated whether the soldiers of the Neotropical termite Nasutitermes corniger improve the foraging decisions. We tested the hypotheses that groups with soldiers (i) are more efficient searching for food, (ii) more efficiently recruit individuals, and (iii) a higher proportion of soldiers results in a more efficient balance between exploitation and exploration of food resources. Using behavioral bioassays under laboratory conditions, we show that the presence of soldiers in termite groups promotes a faster exploitation of the environment that allows them to encounter more food sources simultaneously. However, the presence of soldiers did not significantly increase the attraction of termite groups. Despite that, termite groups with higher soldier proportions were more able to perceive changes in the resource offerings by redirecting individuals to explore more profitable sources. Our results show that the role of soldiers in N. corniger increases the efficiency of termite groups in the exploration and exploitation of food resources.

RESUMO

OBJECTIVES: Our study focused on the impacts on health among adolescents who became members of illegal armed groups in Colombia and their attention within the specialized government programme as seen by the professionals who work directly with them. Previous research indicates that those victims of armed violence are usually highly affected on their emotional and social health, but with appropriate and timely support more serious mental health problems can be prevented. Therefore, the care provided to them should be based on broader and holistic approaches. METHODS: This cross-sectional study used the qualitative method based on semi-structured interviews with 42 professionals, and internal reports on the health condition of 165 adolescents, 57 (34.5%) females and 108 (65.5%) males, as a secondary source of information. All information was anonymous and confidential. RESULTS: The interviews with professionals and their reports demonstrated that about a half of the 165 adolescents, 35 of 57 (61.4%) females and 48 of 108 (44.4%) males, suffered from serious symptoms requiring therapeutic and psychiatric attention. About 20% of the adolescents presented clinically important post-traumatic stress symptoms, 27% admitted sexual abuse and 29% psychoactive substance abuse. The professionals stressed various obstacles to the attention of these multiple impacts related both to the administrative and institutional issues and the particular characteristics of this population. CONCLUSIONS: Our findings show the complexity of the psychosocial impacts among adolescent victims of the Colombian armed conflict and their attention. Highly trained professionals and alternative strategies including active listening, observation and art therapy activities seem to be vital for an effective care. The lessons learned from the Colombian reintegration programme serve as important inputs to be considered when attending children and adolescents from conflict-stricken areas also in other contexts.

RESUMO

Lobomycosis is a disease that is endemic to the Amazon rainforest and is caused by the still uncultured fungus Lacazia loboi. This disease occurs in loggers, farmers, miners, fishermen, and persons living near coastal rivers of this region. We report 6 soldiers in Colombia in whom lobomycosis developed after military service in the Amazon area. The patients had nodular and keloid-like lesions on the face, neck, trunk, and limbs. The duration of illness ranged from 2 years to 15 years. The initial diagnosis was leishmaniasis on the basis of clinical manifestations and direct smear results, but biopsies confirmed the final diagnosis of lobomycosis. Treatment with surgical excision, itraconazole and clofazimine was satisfactory. However, the follow-up time was short. Healthcare professionals responsible for the diagnosis and treatment of skin diseases need to be able to recognize the clinical signs of lobomycosis and differentiate them from those of cutaneous leishmaniasis.

RESUMO

Many ant and termite colonies are defended by soldiers with powerful mandibles or chemical weaponry. Recently, it was reported that several stingless bee species also have soldiers for colony defence. These soldiers are larger than foragers, but otherwise lack obvious morphological adaptations for defence. Thus, how these soldiers improve colony fitness is not well understood. Robbing is common in stingless bees and we hypothesized that increased body size improves the ability to recognize intruders based on chemosensory cues. We studied the Neotropical species Tetragonisca angustula and found that large soldiers were better than small soldiers at recognizing potential intruders. Larger soldiers also had more olfactory pore plates on their antennae, which is likely to increase their chemosensory sensitivity. Our results suggest that improved enemy recognition might select for increased guard size in stingless bees.

RESUMO

The aim of this study was to analyze the morphological and functional changes in military recruits after twelve weeks of physical training. The sample consisted of 130 volunteer recruits aged 18-19 years. Anthropometric variables were assessed (body weight, height, body mass index, arm, waist, and hip circumference, waist/hip ratio, skinfold thickness of the triceps, suprailiac, and abdomen, and body fat percentage) and the sit-up test (1 minute), push-up test, and 12-minute running test. The physical training protocol involved running workouts, strength, agility, and flexibility. Descriptive statistical procedures were performed with mean, standard deviation, variance, and percentage and the comparison between the two moments was performed using the Student t test for dependent samples. The significance level was set at p <0.05. The results demonstrated a decrease in the sum of the three skinfolds (42.7±25.2mm to 33.9±17.7mm), a decrease in fat percentage (14.1±7.3% to 11.8±6.1%), an increase in lean mass (57.6±6.0kg to 58.6±8.0kg), and decreased fat mass (10.1±6.4kg to 8.3±5.2kg). They also showed improvements in push-up test (21.3±9.0 to 33.5±8.9), sit-up test (35.2±8.3 to 49.8±7.4), the 12 minute test (2212±316m to 2760±214m), and V̇O2max (35.2±8.3ml.kg-1.min-1 to 49.8±7.4 ml.kg-1.min-1). No differences were observed in body mass, height, body mass index, or hip circumference. According to the above, it was found that the methodology adopted in the physical training was effective in reducing the percentage of fat and increasing cardiorespiratory fitness, improving the physical capacity and health of the military recruits.

Results: The most important results allows to report that the personnel has high levels of Control, Property and Duration, in reference to the Scope the level is also high but in a lower average to the previous ones. Conclusion: In general terms the sample has a high level of adversity coefficient(AU)

RESUMO

Resumen Este trabajo estudia el papel desempeñado por la Cruz Roja Española (fundada en 1864) en la introducción y difusión de tecnologías humanitarias y el desarrollo de la ciencia médica en España, sirviéndonos del estudio de caso relativo a la atención a soldados enfermos y heridos, repatriados de las guerras de Cuba, Filipinas y Marruecos, y del análisis del impacto que estas medidas tuvieron sobre las necesidades asistenciales y de salud pública de la población civil. El artículo muestra cómo esta organización articuló la provisión de asistencia médica para los soldados españoles, estableciendo una red de centros sanitarios especializados, destinados, posteriormente, también al cuidado de la población civil y a la atención de nuevos problemas de salud pública.


Abstract This article examines the role played by the Spanish Red Cross (founded in 1864) in the introduction and spread of humanitarian technologies and the development of medical science in Spain, using the case study of medical care for sick and wounded soldiers repatriated during the wars in Cuba, the Philippines and Morocco, and analyzing the impact these measures had on health care and public health among the civilian population. The article shows how this organization set up health care for Spanish soldiers, establishing a network of specialized medical centers that were later also used to provide medical care for civilians and to address new public health problems.

RESUMO

Lyme disease (LD) is a natural focal zoonotic disease caused by Borrelia burgdorferi, which is mainly transmitted through infected Ixodes ricinus tick bites. The presence and abundance of ticks in various habitats, the infectivity rate, as well as prolonged human exposure to ticks are factors that may affect the infection risk as well as the incidence of LD. In recent years, 20% to 25% of ticks infected with different borrelial species, as well as about 5,300 citizens with LD, have been registered in the Belgrade area. Many of the patients reported tick bites in city's grassy areas. The aim of this study was to assess the seroprevalence of B. burgdorferi in high-risk groups (forestry workers and soldiers) in the Belgrade area, and to compare the results with healthy blood donors. A two-step algorithm consisting of ELISA and Western blot tests was used in the study. Immunoreactivity profiles were also compared between the groups. The results obtained showed the seroprevalence to be 11.76% in the group of forestry workers, 17.14% in the group of soldiers infected by tick bites and 8.57% in the population of healthy blood donors. The highest IgM reactivity was detected against the OspC protein, while IgG antibodies showed high reactivity against VlsE, p19, p41, OspC, OspA and p17. Further investigations in this field are necessary in humans and animals in order to improve protective and preventive measures against LD.
