International Journal of Exercise Science
International Journal of Exercise Science 17(3): 298-307, 2024. First responders require physical fitness to perform dangerous tasks in unpredictable environments. To promote physical fitness among first responders, many agencies use a peer fitness leader (PFL) approach; however, resources for the fitness, wellness, and health of PFLs are often minimal. This study’s purpose was to investigate the effectiveness of a training workshop to increase PFL’s training knowledge and coaching comfort (CC). Thirty-six PFLs (Experience: 14.6 ± 9.1 yrs; Age: 41.0 ± 9.8 yrs; BMI: 28.9 ± 7.0 kg·m-2) attended a one-day workshop. Paired samples t-tests assessed for differences …

An Analysis Of The Body Drag Test In Law Enforcement Recruits With Consideration To Current Population Demographics, Robert G. Lockie, Matthew R. Moreno, J. Jay Dawes, Robin Marc Orr, Karly A. Rodas, Joseph M. Dulla
International Journal of Exercise Science
International Journal of Exercise Science 15(7): 276-288, 2022. An essential job task for law enforcement officers is a body drag, where they must drag a person from a hazardous environment. In California, a 9.75-m body drag with a 74.84-kg dummy must be completed within 28 s to graduate academy. This mass is less than the average US adult, which may suggest it should be increased. This has not happened due to concerns regarding a potential increase in recruit injuries and failure rates. However, if recruits can complete the drag without formal training, this could leave scope for increasing the mass. …

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 …

Lower-Body Power And Its Relationship With Body Drag Velocity In Law Enforcement Recruits, Matthew R. Moreno, Joseph M. Dulla, J. Jay Dawes, Robin (Rob) Marc Orr, Karly Cesario, Robert G. Lockie
International Journal of Exercise Science
International Journal of Exercise Science 12(4): 847-858, 2019. The body drag (BD) is used as a test to measure a law enforcement officer (LEO) recruit’s capability to rescue an individual. However, the physical characteristics associated with faster BD performance have not been identified. It could be expected that lower- body power, often measured via jump performance, could positively relate to BD performance. This study investigated the relationship between the vertical jump (VJ), peak anaerobic power measured in watts (PAPw), power-to-body mass ratio (P:BM), standing broad jump (SBJ), and relative SBJ, with BD velocity in LEO recruits. Retrospective analysis of data …

International Journal of Exercise Science
International Journal of Exercise Science 11(4): 1063-1073, 2018. The purpose of this study was to investigate the relationships between tests incorporated into a physical assessment battery (PAT) for a law enforcement (LEA) to determine if there were redundancies (i.e. tests measuring the same qualities). A retrospective analysis of 226 recruits (196 males, 30 females) was conducted. The PAT consisted of: maximal push-ups and sit-ups completed in 60 s; a 75-yard pursuit run (75PR); maximal revolutions completed on an arm ergometer in 60 s; and a 2.4 km run. A one-way ANOVA (p<0.05) determined if there were significant differences in the PAT data between the sexes. Pearson’s correlations (p<0.05) calculated relationships between each of the tests within the PAT, and males and females were analyzed separately. Further, tests that could potentially measure similar qualities, including upper-body endurance (push-ups/arm ergometer), abdominal endurance (push-ups/sit-ups), and aerobic fitness (arm ergometer/2.4 km run) were investigated further with one-sample t-tests to determine agreement. Males performed better than the females in all tests (p≤0.017). There were significant correlations …

A Preliminary Analysis Of The Relationship Between The Multistage Fitness Test And 300-M Run In Law Enforcement Officers: Implications For Fitness Assessment, Matthew R. Moreno, Robert G. Lockie, Charles L. Kornhauser, Ryan J. Holmes, J. Jay Dawes
International Journal of Exercise Science
International Journal of Exercise Science 11(4): 730-738, 2018. Law enforcement agencies (LEAs) often use fitness tests to assess recruits and incumbents. One fitness test that is gaining popularity is the 20-meter multistage fitness test (20m-MSFT). However, the potential length of this assessment, in addition to the repeated direction changes, means this test may not be appropriate for all officers (e.g. older officers, or those with physical impairments). The 300-m run is shorter, features no direction changes, and could provide an indication of fitness. The study purpose was to investigate the relationship between the 20m-MSFT and 300–m run. Retrospective analysis of …

Association Of Cardiovascular Fitness And Metabolic Syndrome In Male Police Officers, Matthew S. Schmidt, Steve Martin
International Journal of Exercise Science: Conference Proceedings
Metabolic syndrome has been shown in numerous studies to be related to a higher incidence of coronary artery disease (CAD). A study by Jurca and coworkers (Med. Sci. Sports Exerc 36(8):1301-1307, 2004) found a relationship between aerobic fitness and the prevalence of metabolic syndrome in a group of men enrolled in the Aerobics Center Longitudinal Study (ACLS). In addition, recent work in our lab (Int J Exerc Sci 2(1): S43, 2009) has supported these findings. However, research exploring this relationship is still lacking in male police officers. Previous research has suggested that the prevalence of CAD in police …
