Impacto do core training sobre as dores musculoesqueléticas e o desempenho físico de policiais militares do Batalhão de Operações Especiais da Polícia Militar do Paraná

Abstract

It is known that musculoskeletal pain is among the main problems of Military Police, so mechanisms that relieve this problem may improve the physical performance of Military Police Officers should be created. In addition, the physical performance of Military Police Officers of Paraná is unknown when they are wearing the equipment and arsenals used in their ordinary services. In this way, identifying physical tests and functional tasks near the reality required by institutional mission may be an interesting manner to optimize the police performance during the work routine Mechanisms, such as certain physical exercises directed to reduce musculoskeletal pain may help these officers improve their performance. Consequently, the main objective of this study is to check the impact of Core Training in the musculoskeletal pain report and physical performance of the CHOQUE military police officers, with or without standard equipment. The study lasted eleven (11) weeks and sample of twenty (20) military police officers, an average of 8,93±5,39 years in the PMPR and 6,30±5,11 years of performance in the CHOQUE Police Company (CHOQUE) of Military Police of Paraná. The officers were divided in two groups: the Experimental Group (GE; n=10; 33,9 ±4,14 years) had the a nine (09) weeks increase in Core Training, besides the regular activities of CHOQUE, which involves both instruction and training and the ordinary work which the officers are normally submitted; the Control Group (GC; n=10 29,4 ±3,59 years) followed normally the regular activities in the same period. The Core Training exercises were applied three times a week, in alternate days, following a programmed progression. The Friedman test showed that, compared to the Control Group, the Experimental Group presented significant reductions in musculoskeletal pain report (+10,3% vs - 19,5%; p<0,05), especially in low back pain (-13% vs -44%; p< 0,05). The ANOVA related to repeated measures showed that the Experimental Group presented superior performance in the resistance of isometric strength (ventral plank -18% vs +26%; lateral plank -37% vs +33% p< 0,05). Finally, only the Experimental Group improved its performance in the test specifically developed to evaluate the police demands (+0,31 % vs +10,18% p< 0,05), when the officer wore the physical education uniform, however, this improvement was not reproduced when the officer wore the standard equipment (-2,82% vs +7,86% p> 0,05). According to this study, it was concluded that the Core training is able to reduce musculoskeletal pain and improve the physical performance of military police officers, while they don’t wear standard equipment. The overloading of equipment and arsenals carried by the CHOQUE officers may change their posture during the movements and the exercises applied may not have met this specificity.
