The Eau Claire Police Department, University of
Wisconsin – Eau Claire, and Mayo Clinic conducted
a collaborative research project on the health benefits
of load-bearing vest carriers in comparison to the
traditional police duty belt. This summary will
address why this research occurred, study results and
implementation considerations.
PURPOSE OF THE STUDY
Policing is a physically demanding profession.
Officers wear a duty belt with over 20 pounds of
equipment, spend extended periods of time seated in
a police vehicle and deal with combative people. As
a result, the Eau Claire Police Department has a
number of Officers dealing with lower back and hip
pain. This results in a diminished quality of life, lost
time due to injury and increased healthcare costs that
are shared by our entire community.
The utilization of a load-bearing vest carrier is
commonly viewed as a healthier alternative than the
traditional duty belt for Officers to carry the required
equipment. However, there were several concerns
with transitioning all Eau Claire Police Officers to a
load-bearing vest carrier. These concerns were:
• Lack of published research on efficacy of
load-bearing vest carriers.
• Unintended health consequences of load-
bearing vest carriers.
• A load-bearing vest carrier is inconsistent
with uniform standards.
• Militaristic in appearance, does not conform
to community expectations.
In order to address these concerns collaborative
research project was conducted by the UWEC, Mayo
Clinic and the Eau Claire Police Department.
STUDY DESIGN
The six-month research project was facilitated by Dr.
Jeff Janot, Professor of Kinesiology at UWEC, and
several of his students. Additionally, support was
provided by Mayo Clinic. Fifteen Eau Claire Police
Officers volunteered as participants in this study. For
the first three months of the study, the officers were
divided into two groups, a load bearing vest group
and a duty belt group. After this initial period, officers
were reassigned to the opposite group for the last
three months. The following information was
collected during the research study:
• A biometric screening involving measures of
aerobic fitness, body composition, blood
cholesterol, blood pressure, core endurance,
and spine range of motion.
• An Oswestry Low Back Pain Disability
questionnaire to determine the level of the
officer’s low back functional ability.
• A daily journal self-reporting the level of
lower-back and overall discomfort on a
visual-analog scale utilizing a rating of 0-10
(0 = no pain; 10 = worst pain imaginable).
• Physical activity and sedentary time while on-
duty as measured by accelerometers worn by
each officer.
• Informed consent for the results being shared
amongst the research partners and
documented in a written report.
For the purposes of the study, the following
equipment was moved off of the duty belt onto the
load-bearing vest carrier:
• Handcuffs
• Ammunition magazines
• Pepper spray
• Expandable baton
• Portable radio
• Flashlight
The handgun and electronic control device (Taser)
remained on the duty belt.
