Efeito de diferentes densidades do treinamento de potência na performance física e laboral de policiais militares da Companhia de Operações Especiais-COE

Abstract

The present study aims to analyze how the manipulation of work to rest ratio in power training interferes with the labor performance (physical testes performed with military physical education uniform – MPEU and operational uniform and routine equipment – OURE), maximum strength, agility, endurance and power, as well as assessing changes in electromyographic activity, metabolic and anthropometric in elite police officers. It is known that wort to rest ratio of power training can be a factor in the optimization of motor functions, which can represent the best performance in high-risk police events. The study lasted 10 weeks, using a sample of 14 military elite policemen (15.36 ± 6.36 years of service). The military personnel were selected for convenience and the allocation into two groups was random. The High Work to Rest Ratio Group (HWRR Group; n = 07; 38.29 ± 6.27 years) performed 12 (twelve) sets of 03 (three) repetitions with a rest interval of 27 (twenty-seven) seconds between sets (12x3: 27s; density = 0.12) and the Low Work to Rest Ratio Group (LWRR Group; n = 07; 38.29 ± 7.48 years) that performed 6 (six) series of 06 (six) repetitions with an interval of 180 (one hundred and eighty) seconds between sets (6x6: 180s; density = 0.04). Both groups undertook 8 weeks of power training, in addition to the regular activities performed by the Company, which involve all the instruction, training and routine work that police officers do. The anova for repeated measurements revealed that: in the post training (p 0,05), the HWRR Group was superior to the LWRR Group in the production of medium power (in the MPEU and OURE conditions), in peak power production (in MPEU condition) related to squat, in strength endurance, in reducing peak torque, and in the rate of torque development for isometric knee extension. There was no significant difference in the agility test regarding the holster arrangement (OURE with holster at the waist and OURE with femoral holster), but the use of OURE compromised the volunteers’ agility in relation to MPEU. The results show protocols provide greater benefits to elite police officers. The conclusion was that the high work to rest ratio protocol proved to be more productive in terms of physical performance, in addition to being able to be executed in less time, which allows its better adaptation to the police work routine.
