IntroductionThe practice of physical activity is directly related to the maintenance of
health. Thus, the individual who is in the habit of practicing and who is
well conditioned is able to perform various day-to-day functions with the
least possible effort. In addition, good physical fitness is a requirement
made for professionals of different categories, such as members of the
security forces. Within this context, the military police officer must be
within the standards of physical activity in order to exercise their
ostensive functions. CrossFit is a training method that uses high intensity
functional movements and aims to improve the physical form and health of the
practitioner, thereby influencing its physical capacities.ObjectivesTo assess the physical fitness of military police officers who practice
CrossFit.MethodsThe sample consisted of 16 male active military police officers,
practitioners of the institutional physical exercises, divided between
CrossFit practitioners for at least 5 months (n = 10) and non-practitioners
of extra-institutional exercises (n = 6). The following parameters were
evaluated: level of physical activity, body mass index, fat percentage,
flexibility, upper limb strength, and cardiorespiratory capacity.ResultsThe practice of CrossFit complementary to military physical training
increased the values of upper limb strength, flexibility, and
cardiorespiratory capacity among the components of physical fitness that
were evaluated.ConclusionsThe regular practice of CrossFit by military police suggests positive
interference in some of the components of physical fitness and in the
balance in strength gain, however more studies need to be conducted to
investigate the significance of this effect.
