Description of the Anthropometric and Physiological Profile of Tactical Officers

The purpose of this study was investigate the current physical and performance characteristics of tactical officers on full-time, part-time and multi-jurisdictional teams and to identify the underlying physical fitness components required to perform the essential job-tasks of SWAT. A descriptive statistical analysis, One-way ANOVA with Tukeys' post-hocs and independent sample t-tests were used to compare differences in mean anthropometric and performance scores among three groups of tactical officers. In addition, a discriminate analysis with stepwise linear regressions was used to predict group membership. One sample t-tests were utilized to determine differences between the mean scores of the tactical officers and traditional law enforcement officers, as well as the Cooper Single Standard -Fitness Norms. The full-time tactical officers had significantly less fat mass and scored significantly better on measures of muscular endurance and anaerobic power than both the part-time and multi-jurisdictional tacticaSchool of Teaching and Curriculum Leadershi

Associations between anthropometric characteristics and physical performance in male law enforcement officers: A retrospective cohort study

BACKGROUND: Police officers are often required to undertake physically demanding tasks, like lifting, dragging and pursuing a suspect. Therefore, physical performance is a key requirement. METHODS: Retrospective data for 76 male police officers (mean age = 39.42 ± 8.41 years; mean weight = 84.21 ± 12.91 kg) was obtained. Data included anthropometric (skinfolds, estimated percentage body fat, lean body mass and fat mass) and physical performance (1 Repetition Maximum Bench Press, 1–min sit-ups, 1-min push-ups, vertical jump, 300 m run, 1.5 mile run) measures and correlations between anthropometric measurement and fitness score were obtained. RESULTS: Estimated percentage body fat was significantly (p ≤ .001) and negatively correlated with all performance measures, except sit-ups and 300 m and 1.5 mile run performance. Estimated lean body mass was significantly and positively (p ≤ .001) correlated with push-ups, bench press and vertical jump measures, while increasing estimated fat mass was significantly (p ≤ .001) associated with reduced performance on sit-up, vertical jump, 1.5 mile run and estimated maximal voluntary oxygen uptake. CONCLUSIONS: A targeted approach, going beyond just decreasing percentage body fat to also selectively increasing lean mass, should be applied for optimal improvement in physical fitness performance

Predicting performance on the NFL-225 bench press test using bar velocity

BACKGROUND: Bar velocity has been proved to accurately predict performance in several exercises. OBJECTIVE: To estimate the total number of repetitions during the NFL-225 Bench Press Test (NFL-225) based on bar velocity in collegiate football players. METHODS: Forty-six NCAA Division I football players performed as many bench press repetitions as possible with a standard load of 225 lbs. The variables used to estimate the total number of repetitions were: mean velocity of the fastest repetition achieved in the test (FR); mean velocity of the first repetition (V1); mean velocity of the first three repetitions (MV3); mean velocity of the first five repetitions (MV5); and mean velocity of the first 10 repetitions (MV10). Linear regression analyses were conducted to predict NFL-225 performance based on bar velocity. RESULTS: The prediction of the total number of repetitions was similar between the five mean velocities (FR: R-2 = 0.64, SEE = 3.87, V1: R-2 = 0.65, SEE = 3.80, MV3: R2 = 0.70, SEE = 3.52, MV5: R-2 = 0.71, SEE = 3.48, and MV10: R-2 = 0.62, SEE = 3.37). CONCLUSION: The mean velocities allowed the production of general regression equations for the estimation of the total number of repetitions in the NFL-225. V1 and MV3 presented as the best options due to their accuracy, time-efficiency, and reduced musculoskeletal stress
