Impact of different personal protective clothing for firefighters in mountain areas.

Background: Mountain hiking is an unpredictable activity for firefighters during the search, rescue, and firefighting. Could the quality of the uniform worn by firefighters affect psychophysiological variables?

Objective: The objective of this study was to monitor the responses of perceived exertion (RPE), musculoskeletal pain (MP), and heart rate variability (HRV) responses in firefighters using different uniforms on a 5 km mountain walking activity. The feeling of comfort, safety, and ergonomic adjustment of the two types of uniforms also was verified.

Can training trunk musculature influence musculoskeletal pain and physical performance in military police officers?

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.
