AB  - Change-of-direction speed (CODS) directly impacts success in sports, police, and military performance. Movements requiring CODS are often preceded by aerobic or anaerobic running. Therefore, this study investigated the effects of maximal and submaximal anaerobic and aerobic running on subsequent CODS performance. A sample of 50 police students (42% female and 58% male) performed a maximal 300-yard shuttle run test (SR300y) and a 2.4-km Cooper test (CT2.4km) at maximal effort and also at 95, 90, 85, 80, and 75% of maximal effort. CODS was assessed using the Illinois Agility Test (IAT) immediately following each intensity level of each test at 12 separate testing sessions. To avoid fatigue, the period between each consecutive session was a minimum of 3 days. Paired samples t-tests were used to determine the differences between the two conditions (anaerobic lactic and aerobic) and for the IAT. A repeated measure analysis of variance with a Bonferroni post hoc test was used to analyze partial effects of different running intensities on the IAT. A significant reduction in speed was observed between the initial IATmax time and the IATmax time after performing the SR300y at intensities of 95, 90, 85, and 80% of maximal speed on this test. IAT performance was significantly slower when performed after the CT2.4km at 95 and 90% of maximal aerobic speed. The effects of the SR300y on the IAT were significantly greater than the effects of the CT2.4km. No significant differences were found by sex. Building up to 90% intensity, anaerobic running has a greater negative impact on subsequent CODS performance than does aerobic running.

AB  - Introduction. A career in law enforcement is physically and mentally demanding, contributing to increased health risks and occupational stress. Physical activity and healthy eating are beneficial for maintaining a healthy weight and preventing many chronic health conditions (e.g. heart disease, cancer). While most police students must pass a fitness exam to enter training and again before becoming sworn police officers, it is unclear whether academy training prepares officers to develop healthy dietary habits for their careers. This study aimed to investigate typical
dietary habits of police students at the University of Criminal Investigation and Police Studies, Belgrade, Serbia, and determine ways to improve officer education in healthy eating. Methods. A sample of police students (n = 137, 36.5% female) of average age 20.2 years participated in a survey to evaluate their typical dietary habits. Descriptive statistics were used to describe their nutritional behaviors. Results. Overall, the results suggest that most students make good nutrition decisions. The majority (78.1%) of students reported using alcohol responsibly, and 74.45% drank water between meals, though only 6.6% of students ate enough fruit every day. Almost all (98.5%) understood the importance of diet, but only 11.7% received nutrition-related information from a school source. Conclusion. Results suggest that police student training should include nutritional education and physical preparation for holistic police officer development. This approach could help prevent poor health outcomes for police officers.

AB  - This study investigated differences in the body composition of police officers from different occupational groups and the moderation effects of leisure time physical activity (LTPA). A sample of 237 police officers (special anti-terrorist unit, gendarmerie, firefighters, and general duties) participated in the study. Body mass index (BMI), percent of body fat (%BF), percent of skeletal muscle mass (%SMM), and index of hypokinesia (IH) were assessed using a multichannel bioelectric impedance analyzer and officers reported the amount of LTPA using an international physical activity questionnaire. The sample was divided in three groups relative to LTPA, sedentary (0-149 min/week), moderately active (150-299 min/week), and very active (300+ min/week). Multiple analysis of variance (4 × 3) was used to analyze if occupational groups differed based solely on occupation, if officers from the same occupation differed in muscularity and fatness based on LTPA, and if any differences in body composition occurred between officers from different occupations with the same level of LTPA. Police officers from more physically demanding occupations demonstrated lower %BF and IH, while having higher %SMM. This was also observed among the officers of the same occupation who reported a higher LTPA, while officers who reported very high LTPA had similar body composition.
