Traditional knowledge is an important source of obtaining new phytotherapeutic agents. Ethnobotanical survey of medicinal plants was conducted in Nossa Senhora Aparecida do Chumbo District (NSACD), located in Poconé, Mato Grosso, Brazil using semi-structured questionnaires and interviews. 376 species of medicinal plants belonging to 285 genera and 102 families were cited. Fabaceae (10.2%), Asteraceae (7.82%) and Lamaceae (4.89%) families are of greater importance. Species with the greater relative importance were Himatanthus obovatus (1.87), Hibiscus sabdariffa (1.87), Solidago microglossa (1.80), Strychnos pseudoquina (1.73) and Dorstenia brasiliensis, Scoparia dulcis L., and Luehea divaricata (1.50). The informant consensus factor (ICF) ranged from 0.13 to 0.78 encompassing 18 disease categories,of which 15 had ICF greater than 0.50, with a predominance of disease categories related to injuries, poisoning and certain other consequences of external causes (ICF  =  0.78) having 65 species cited while 20 species were cited for mental and behavioral disorders (ICF  =  0.77). The results show that knowledge about medicinal plants is evenly distributed among the population of NSACD. This population possesses medicinal plants for most disease categories, with the highest concordance for prenatal, mental/behavioral and respiratory problems.

B Objective: analyze the agreement of the V̇O2max values estimated by American College of Sports Medicine‎ and Foster equations with direct measure gas analyze in young Brazilian males. The maximal oxygen uptake, as a health indicator and mortality predictor, can be assessed in different ways. The gold standard comprises the direct measurement of exhaled gases, which entails high cost. A more conveniently form can be estimation equations. Materials and methods: this study assessed VO2max of 41 young Brazilian males (21.4 ±2.2 years) by cardiopulmonary exercise test in a treadmill ergometer with a ramp protocol. Bland and Altman analysis was performed to verify the agreement between V̇O2max measured and estimated values by ACSM and Foster equations. Results: the measured VO2max was 52.3 ± 4.9 ml.kg-1.min-1. The difference between the measured V̇O2max and the estimated V̇O2max by the ACSM equation (9.40±3.67) was approximately 7.5 times greater than the difference between the measured V̇O2max and estimated V̇O2max by Foster's equation (1.25±3.46). Bland Altman graphics shows that only ACSM equation had mean differences that were significantly different from the measured value. Conclusions: the ACSM equation showed not appropriate for during treadmill stress testing young adults in a ramp protocol and Foster equation seems to be a more accurate estimator of V̇O2max for this population, besides showed a bias along the aerobic capacity, trending to overestimates and underestimates V̇O2max of least and most fit people, respectively.

Following the increase in the employment of women in conflicts around the world, the federal government of Brazil enacted a law which determines the participation of women in the military. The aim of this study was to analyze the effect of six months of physical training (PT) on the physical fitness of young Brazilian Army cadets to carry out the physical assessments provided in military training. Sixty-eight members of the (19.4 ± 1.0 years) military from the Brazilian Army (BA), with BMI of (23.61 ± 2.17/21.81 ± 2.26) respectively and divided in two groups (men/women) participated in the study. PT was conducted by Manual EB20-MC10.350. Anthropometric measurements and assessment of body composition by dual X-ray absorptiometry were performed. The Student’s t test, percentage evolution equation, and Levene test were used. Results showeda significant increase in anthropometric variables and cardiorespiratory fitness in both groups. Bone health variables and visceral fat presented a significant increase in the malegroup. In terms of muscle fitness (handgrip and isometric strength of the legs and push-up and pull-up), there was no significant variation between thegroups. Percentage evolution was greater in female group. The conclusion shows PT was able to cause beneficial changes, promoting positive improvement in bone health, especially in women. Also, PT was shown to enhance cardiorespiratory capacity, and muscle fitness of the upper limbs in all participants.

The incidence of musculoskeletal injuries (MSIs) is a constant concern in all Armed Forces. Among risk factors for MSIs, physical training and sports can be considered the most frequent cause in military. In this sense, the aim of this study was to investigate the incidence rate of musculoskeletal injuries, identifying the anatomical distribution and its association with risk factors such as: body composition, age and physical training over the past 12 months. Three hundred fifty-one male cadets from the first year of the Brazilian Army officers training course and four hundred and fifty six students from the logistics sergeants training course (three hundred seventy-five male and eighty one female) volunteered to fill in a self-reported questionnaire which was developed based on a literature review and the clinical experience of the investigators. It contained questions concerning anatomical site of the MSIs, hours of physical activities per week, type of activities at the moment of injury and days of absences in physical activities. Among 807 subjects studied, 180 military have reported 220 MSIs. From this total, 143 have presented a single injury, 34 have suffered two injuries and three subjects have had three injuries each one during the last 12 months. Knee was the anatomical site with the higher incidence (7.06%) of MSIs over a 12-month period. Running was the activity with the higher incidence (11.77%) of injuries over a 12-month, accounting for 43.18% of all MSIs. When considered all activities of physical training, the MSIs incidence rate over a 12-month was 17.97%, which represents 71.36% of all MSIs. In young militaries, the largest amount musculoskeletal injuries occurred in the lower extremities and during military physical training, with running being the main activity in which the injuries occurred. Population, gender and body composition was not significantly associated with these types of injuries, while older age was associated in this study. The gradual and systematic progression of distance and speed during running training should be emphasized to prevent MSIs.

La influencia del calentamiento activo, con o sin estiramiento estático, sobre la fuerza muscular en militares brasileños L'influence de réchauffement actif, avec ou sans étirement statique, sur la force musculaire des militaires brésiliens A Influência do aquecimento ativo, com e sem alongamento estático, na força muscular de militares brasileiros Abstract. The aim of this study was to compare the influence of active warm-up with or without static stretching on torque values generated in equipment isokinetic to knee joint. It was a cross-section study, comparative, which evaluated the maximum strength of knee extensors and flexors on an isokinetic dynamometer at the speed of 60°/s. Twelve (12) military were evaluated, all sex male, with average age group of 25 years old ±2.5; in relation to a body mass and stature, the average values and standard deviation were 75 ± 7.5 Kg e 1.71 ± 0.1 m. Significant differences were observed on peak torque values of the knee extensors (p=0.034), knee flexors (p=0.028) and maximum peak torque values of knee flexors (p=0.034) between the tests preceded by warm-up with static stretching and the ones preceded by warm-up without stretching. There was no significant difference to maximum peak torque values of knee extensors (p=0.071). It can be understood that the active warm-up with static stretching before the maximum strength test on the isokinetic (60°/s) promotes an increasing on peak torque values of knee extensors and flexors as much as in the average values as in the maximum ones, in absolute terms, although the maximum peak torque of the extensors have not exhibited significant differences. Keywords: knee extensors; knee flexors; maximum peak torque; strength test; warm-up.Resumen. La propuesta de este estudio fue comparar la influencia del calentamiento activo con y sin estiramiento estático en los valores de torque generados en el equipo isocinético para la articulación de la rodilla. Se trata de un estudio transversal, comparativo, que evaluó la fuerza máxima de los extensores y flexores de la rodilla en un dinamómetro isocinético a la velocidad de 60°/s. Se evaluaron doce militares, todos del sexo masculino, con una edad media de 25 ± 2,5 años. En relación con la masa corporal y la estatura, los valores de la media y la desviación estándar fueron: 75±7,5 kg y 1,71±0,1 m. Se observaron diferencias significativas en los valores del pico medio de par de los extensores de la rodilla (p=0,034), flexores de la rodilla (p=0,028) y valores del pico máximo de torque de los flexores de la rodilla (p=0,034) entre las pruebas precedidas de calentamiento con estiramiento estático y aquellas precedidas de calentamiento sin estiramiento. No hubo diferencia significativa en los valores del pico máximo de torque de los extensores de la rodilla (p=0,071). Se puede concluir que el calentamiento activo con estiramiento estático antes de la prueba de fuerza máxima en el isocinético (60º/s) promueve un aumento en los valores del pico de torque de los extensores y flexores de la rodilla tanto...
