TL;DR: In this article, the authors investigated the associations between body composition and measures of physical fitness, and their use to predict estimated physical fitness score (EPFS), and obtained prediction models may be a promising screening method of a POs' fitness, when conducting the physical tests is not possible or safe (obese and injured POs or bad weather conditions).
Abstract: Research with police officers (POs) suggests an association between body composition, physical performance and health. The aim of the study was to investigate the associations between body composition and measures of physical fitness, and their use to predict estimated physical fitness score (EPFS). The sample included 163 male POs (age = 31.61 ± 4.79 years, height = 172.97 ± 6.09 cm, body mass = 77.53 ± 11.66 kg). Eight body composition variables: body mass index (BMI), body fat mass index (BFMI), percent of body fat (PBF), percent skeletal muscle mass (PSMM), index of hypokinezia (IH), skeletal muscle mass index (SMMI), protein mass index (PMI), and fat-free mass index (FFMI); and four physical fitness measures: a 3.2 km run, a 2-minute push-up, 2-minute sit -up and estimated physical fitness score (EPFS) were correlated, followed by the regression analysis for causal relationship between bo dy composition and EPFS. Running 3.2 km test correlated to BMI, PBF, PSMM, BFMI, and SMMI (r = 0.274, 0.250, -0.234, 0.311, p<0.01 , respectively); 2-minute push-up correlated to PBF, PSMM, BFMI, SMMI, PMI, IH, and FFMI (r = -0.413, 0.436, -0.375, 0.221, 0.231 , -0.411, 0.261, p<0.01, respectively); 2-minute sit-up correlated to PBF, PSMM, BFMI, and IH (r = -0.237, 0.250, -0.236, -0.218, p<0.01, respectively); and EPFS correlated to BMI, FFMI, PBF, PSMM, BFMI, and IH (r = -0.200, 0.168, p<0.05, and r = -0.369, 0.378, 0.3 76, -0.317, p <0.01, respectively). Two models of predictions were extracted: 1) PBF, BFMI, PMI and FFMI (R 2 = 0.250, p<0.001); 2) PBF, BFMI and PMI (R = 0.244, p<0.001). Obtained prediction models may be a promising screening method of a POs’ fitness, when conducting the physical tests is not possible or safe (obese and injured POs or bad weather conditions).

TL;DR: A progressive physical training program that incorporates mesocycles and midpoint evaluations can have a positive impact on the fitness of trainees even when undergoing a busy academy program.
Abstract: Cvorovic, A, Kukic, F, Orr, RM, Dawes, JJ, Jeknic, V, and Stojkovic, M. Impact of a 12-week postgraduate training course on the body composition and physical abilities of police trainees. J Strength Cond Res 35(3): 826-832, 2021-The main objective of this study was to determine the effects of a 12-week physical training program on police trainees at the Abu Dhabi Police College. Anthropometric and fitness testing data for 325 healthy trainees, enrolled in an academic course for qualification as a police officer, were analyzed. The trainees were tested 3 times, during the initial (week 1), midpoint (week 7), and final testing (week 13) phases of the training program. The tested variables included anthropometry (body mass [BM]), body composition (body mass index [BMI]; waist circumference [WC]; waist-to-height ratio [WHtR]), upper-body muscular endurance (1-minute push-up [PU]), trunk muscular endurance (1-minute sit-up [SU]), and aerobic endurance (2.4-km run [RUN]). A 1-way analysis of variance with post hoc Bonferroni adjustment was performed to investigate the changes in anthropometry and fitness across the 3 testing periods with percentages of change calculated at each testing stage. Alpha levels were set at 0.05 a priori. Statistically significant differences (range of p values from p < 0.001 to p < 0.05) were found in all tested variables (BM, BMI, WC, WHtR, PU, SU, and RUN) and between all testing stages (initial, midpoint, and final). A progressive physical training program that incorporates mesocycles and midpoint evaluations can have a positive impact on the fitness of trainees even when undergoing a busy academy program.

TL;DR: While unloaded agility test performance was strongly associated with loaded performance, female police officer CODS was significantly reduced when carrying occupational loads.
Abstract: Female police officers may be required to pursue offenders on foot while wearing occupational loads. The aim of this study was to determine relationships between fitness measures and change of direction speed (CODS) in female police officers and the influence of their occupational loads. Retrospective data were provided for 27 female police officers (age = 32.19 ± 5.09 y, height = 162.78 ± 5.01 cm, and mass = 71.31 ± 13.42 kg) and included fitness measures of: lower-body power (standing long jump (SLJ)), upper-body and trunk muscle endurance (push-up (PU) and sit-up (SU)), aerobic power (estimated VO2max), and CODS (Illinois agility test). The CODS test was performed without and with occupational load (10 kg). Paired sample t-tests (between-load conditions) and Pearson's correlations (relationships between measures) were performed with linear regression analysis used to account for the contribution of measures to unloaded and loaded CODS performance. CODS was significantly slower when loaded (unloaded = ~23.17 s, loaded = ~24.14 s, p < 0.001) with a strong, significant relationship between load conditions (r = 0.956, p < 0.001). Moderate to strong, significant relationships were found between all fitness measures ranging from estimated VO2max (r = -0.448) to SU (r = -0.673) in the unloaded condition, with the strength of these relationships increasing in the loaded condition accounting for 61% to 67% of the variance, respectively. While unloaded agility test performance was strongly associated with loaded performance, female police officer CODS was significantly reduced when carrying occupational loads. A variety of fitness measures that influence officer CODS performances become increasingly important when occupational loads are carried.

TL;DR: Body height seems to be an important factor for the performance of the basketball team at the FIBA-WC because of the difference between the basketball players from the teams ranked 1–16 and those ranked below 16th place.
Abstract: Body height is among the most important attributes of basketball players. Whether it differs among the basketball players who compete at the world basketball championship (FIBA-WC) is unknown. The aim of this study was to investigate the differences between the basketball players from the teams ranked 1–16 and those ranked below 16th place. The body heights of all players from the last three FIBA-WCs were collected and allocated according to the ranking at the FIBA-WC and analyzed by position in team. An independent sample t-test was conducted to analyze the difference in body height of players ranked 1–16 and players who ranked below 16th place. The players from the first 16 teams were significantly taller at three positions: point guards (Difference = 2.92 cm, p < 0.05), shooting guards (Difference = 2.16 cm, p < 0.05), and small forwards (Difference = 2.49 cm, p < 0.01). Body height seems to be an important factor for the performance of the basketball team at the FIBA-WC. Considering that all players at the FIBA-WC went through rigorous selection process to be in their national teams, body height of the higher-ranked players could be used as a reference value.

TL;DR: In this article, 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 for police officers.
Abstract: 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.
