The Influence of Aerobic Fitness on Heart Rate Responses of Custody Assistant Recruits during Circuit Training Sessions

Abstract

This study captured heart rate (HR) responses of custody assistant (CA) recruits undertaking circuit training sessions. Data from 10 male and 12 female CA recruits were analyzed. Based on YMCA step test recovery HR, recruits were divided into higher fitness (HF; top 25%), lower fitness (LF; bottom 25%), and moderate fitness (MF; remaining recruits) groups. HR was measured during two circuit training sessions featuring calisthenics and running. HR zones were defined as: very light (<57% of age-predicted maximum heart-rate [HRmax]); light (57–63% HRmax); moderate (64–76% HRmax); vigorous (77–95% HRmax); and very vigorous (>95% HRmax). A one-way ANOVA, with Bonferroni post hoc, calculated between-group differences in time spent, and percentage of total time, in the HR zones. In session one, the LF group spent less time in the light training zone compared to the MF group, and more time in the very vigorous zone compared to the HF group (p = 0.027–0.047). In session two, the LF group spent more time in the moderate zone compared to both groups, and a greater percentage of time in the very vigorous zone compared to the MF group (p = 0.002–0.004). LF recruits generally worked harder during circuit training than their fitter counterparts, which supported recommendations for ability-based modifications.

How Does Time Spent Working in Custody Influence Health and Fitness Characteristics of Law Enforcement Officers?

“…A univariate ANCOVA was used to determine whether there were significant differences between the groups. Within these groups, the sexes were combined [21,44,56]. Nevertheless, sex was used as a covariate as previous research has illustrated between-sex differences in the physical performance of law enforcement personnel [14,20,22,52,[60][61][62][63][64].…”

“…The YMCA step test was administered as a fitness assessment to measure aerobic capacity, and was administered via set procedures [54][55][56]. This test has been used to assess aerobic fitness in custody assistant recruits [56], highlighting its applicability for LEOs. The test was performed with approximately 12 inch (~31 cm) high bleacher seats used for the step on an indoor basketball court.…”

“…The beat was played from an iPad handheld device (Apple Inc., Cupertino, CA, USA) connected to a portable speaker (ION Block Rocker, Cumberland, RI, USA) positioned on a bleacher seat in front of the officers. Following the 3-minute time period, LEOs immediately sat on the step while recovery HR was manually taken by a staff member via the carotid or radial artery for 60 s [55][56][57].…”

The Impacts of Plyometric Circuit Training before and after Technical Training on Cardiorespiratory and Power Abilities of Junior Male Volleyball Athletes

“…This circuit training is usually seen as a general physical and technical improvement or an evaluation of the previous period [10,12,13]. In the implementation, many athletes have plyometric training methods using a circuit before and after technical training [14] This study aimed to reveal the differences between physical and circuit training when they were done before and after technical training the increase cardiorespiratory and power abilities. By knowing these differences, the coach could determine the suitable circuit training model to obtain the training objectives as expected.…”
