ABSTRACT
To investigate the effect of a Trunk Training (TT) program on the general musculoskeletal pain (GMP) and physical performance of Military Police Officers. Twenty officers were divided into either control group (CG) or TT group (TTG). Both groups performed nine weeks of traditional physical training. However, the TTG had 25-minutes allocated to TT during each scheduled physical training period. Anthropometric, trunk endurance, and physical fitness tests were completed pre- and post-training for both groups. Both groups also answered a weekly questionnaire about their GMP. Post-training, trunk endurance performance was significantly higher (p < 0.05) and the GMP significantly lower (p < 0.05) in the TTG when compared to the CG. Improvement in side plank test scores was associated with a decreased in GMP (r = -0.495, p < 0.05). TT can reduce the perception of GMP in addition to increasing the endurance of the trunk muscles. The side plank was the only physical test associated with GMP. Practitioner summary: Trunk Training can reduce general musculoskeletal pain and increase the endurance of the trunk muscles without a concomitant loss in general fitness in elite Military Police Officers. This research lasted 11 weeks and presents real-world and pragmatic findings.

INTRODUCTION: Physical fitness is crucial for the work of military police officers. Over time, officers show a substantial decrease in physical fitness. State military officers must undergo a physical fitness test every year, but prior to 2015, failure on this test had no impact on career advancement. State Law No. 18.659/2015 included passage of the physical fitness test as a requirement for promotion for officers in the Paraná military police (Polícia Militar do Paraná). OBJECTIVES: To verify whether the obligation to undergo the physical fitness test had any effects on the physical performance of military police officers. METHODS: The physical fitness tests results from 2016-2019 (n = 1705) were entered into an electronic spreadsheet and stratified by year. The spreadsheet included scores on individual tests (shuttle run, upper body and 12-minute run) as well as the sum total across all tests. Then, descriptive statistics, normality test, Kruskal-Wallis H test, and post-hoc comparisons were performed using the Mann-Whitney U test. with a significance level of p < 0.05. RESULTS: Significant differences (p < 0.05) were observed on all variables in the physical fitness test when compared between the years of 2016, 2017, 2018 and 2019. Mean scores on the shuttle run (96.91 ± 7.54) and upper body tests (82.60 ± 24.81) were highest in 2019, while the mean score on the 12-minute run test was highest in 2017 (60.33 ± 28.38). The effect size of these differences (r) was small. CONCLUSIONS: The evidence suggests that the inclusion of the physical fitness test as a requirement for promotion can contribute to the improvement of physical performance in military police officers.

Resumen Introducción La falta de actividad física, junto con el consumo inadecuado de alimentos, ha sido uno de los tópicos más presentes en la investigación sobre mortalidad y las enfermedades crónicas no transmisibles. Por ello, conocer el nivel de actividad física en escolares ostenta gran importancia, puesto que podrían desplegarse acciones para disminuir los alarmantes niveles de sedentarismo, especialmente desde la asignatura de Educación Física. Objetivo Examinar sistemáticamente el nivel de actividad física autoinformado en escolares no exentos de la participación en las sesiones de Educación Física. Método Revisión sistemática de estudios transversales que determinaron el nivel de actividad física autoinformado a través del cuestionario PAQ-C. Resultados Se identificaron 23 artículos mediante la búsqueda en cinco bases de datos distintas, entre 2014 y 2019. Para la selección de los artículos, fue preciso considerar el tipo de estudio y lugar de realización, la fase etaria analizada, así como la no participación en las sesiones de Educación Física. Conclusiones La mayoría de estudios analizados señalan unos niveles insuficientes de la misma; no obstante, resulta necesario llevar a cabo más investigaciones relacionadas con el nivel de actividad física autoinformado, para diagnosticar con mayor precisión la realidad de los niños en edad escolar.

Abstract Introduction The lack of physical activity, together with inadequate food consumption, has been one of the most present topics in research on mortality and chronic non-communicable diseases. Therefore, knowing the level of physical activity in schoolchildren is of great importance, since actions could be deployed to reduce the alarming levels of sedentary life, especially from the subject of Physical Education. Objective To systematically examine the level of self-reported physical activity in schoolchildren not exempt from participation in Physical Education sessions. Method A systematic review of cross-sectional studies that determined the level of self-reported PAQ-C questionnaire. Results Twenty-three articles were identified by searching five different databases between 2014 and 2019. For the selection of the articles, it was necessary to consider the type of study and location, the age phase analyzed, as well as the non-participation in the Physical Education sessions. Conclusion Most of the studies analyzed indicate insufficient levels of physical activity; however, it is necessary to carry out more research related to the level of self-reported physical activity, enabling to diagnose with greater precision the reality of school-age children.
