Forces At The Feet, Gait Timing, And Trunk Flexion/Extension Excursion While Walking With A Gear Belt Or Gear Vest Load, Shane S. Maher, Laura L. Dill, Jennifer L. Hein, Jeff A. Nessler, Deanna J. Schmidt
International Journal of Exercise Science
International Journal of Exercise Science 15(1): 36-44, 2022. Law enforcement personnel often carry gear loads, which have a history of causing low back pain. The aim of this study was to evaluate the differences in gait and trunk posture for gear load carried on a gear belt and a gear vest. Twenty-nine participants performed load carriage in three conditions: a no load control trial (C), a symmetrically loaded gear belt (GB), and an anterior-loaded gear vest (ALV). Gear conditions had 9.07 kg of additional mass. Motion capture and insole force sensors were used to collect data while participants walked on …

The Effects Aerobic Fitness Has On Heart Rate Responses For A Custody Assistant Recruit Class Performing A Formation Run, Karly Rodas, Matthew Moreno, Ashley Bloodgood, J. Jay Dawes, Joseph Dulla, Robin Marc Orr, Robert G. Lockie
International Journal of Exercise Science
International Journal of Exercise Science 14(4): 1219-1233, 2021. This study measured the heart rate (HR) responses to a formation run (group run completed along a set route) performed by higher fitness (HF), moderate fitness (MF), or lower fitness (LF) custody assistant (CA) recruits. Retrospective data from 26 recruits (12 males, 14 females) were analyzed. Prior to academy training, a YMCA step test was administered. Recruits were divided into three groups based on recovery HR: top 25% were HF; bottom 25% were LF; the rest were MF. Recruit HR was measured during a formation run completed at an ~11-minute mile· pace …
Relationships Between Absolute And Relative Lower-Body Power And Foot Pursuit Ability In Law Enforcement Recruits, Robert G. Lockie, Robin Marc Orr, Joseph Dulla, J. Jay Dawes
Relationships Between Absolute And Relative Lower-Body Power And Foot Pursuit Ability In Law Enforcement Recruits, Robert G. Lockie, Robin Marc Orr, Joseph Dulla, J. Jay Dawes
International Journal of Exercise Science
International Journal of Exercise Science 14(3): 1078-1089, 2021. An essential job task for law enforcement officers is a foot pursuit. Lower-body power should aid foot pursuit ability; however, there has been minimal investigation of this relationship. This study investigated relationships between absolute and relative lower-body power measured by the vertical jump (VJ) with the 75-yard pursuit run (75PR), which is a change-of-direction (COD) speed test that simulates a foot pursuit in law enforcement recruits. Data from 487 male and 95 female recruits who completed the VJ and 75PR prior to academy training was analyzed. VJ variables included VJ height, relative …
Are There Differences In Fitness Between Recruits From Larger (Hosting) And Smaller (Participating) Law Enforcement Agencies?, Erika Hernandez, J. Jay Dawes, Robin Marc Orr, Joseph Dulla, Robert G. Lockie
Are There Differences In Fitness Between Recruits From Larger (Hosting) And Smaller (Participating) Law Enforcement Agencies?, Erika Hernandez, J. Jay Dawes, Robin Marc Orr, Joseph Dulla, Robert G. Lockie
International Journal of Exercise Science
International Journal of Exercise Science 14(4): 885-901, 2021. Law enforcement agencies often conduct academy training classes that include recruits hired by both the larger hosting agency (HA), and by smaller participating agencies (PA). HAs that need to fill more positions may have recruits with a wide range of fitness levels. Smaller agencies may be more selective in their hiring as they do not have as many available positions. This study compared HA and PA recruit fitness prior to academy. Retrospective analysis was conducted on 11 academy classes, incorporating 742 HA recruits (602 males, 140 females) and 99 PA recruits (82 …
