Introduction: Although the daily tasks of police officers are mostly sedentary, optimal body composition and physical abilities are important for the occasional high intensity task duties that may occur and for general health. However, the nature of policing (e.g. shift work, long work hours) may negatively impact an officer’s body weight and physical activity patterns and is therefore associated with increased health risks. The aim of this study was to evaluate the effects of a 12-week physical training program and a caloric deficit nutritional plan on police trainees.Methods: Fifty-five (n = 55) male trainees (mean age = 28.51 ± 5.26 years, mean body height (BH) = 174.58 ± 5.79 cm, mean body mass (BM) = 97.67 ± 11.21 kg) were included in this analysis. A 12-week physical training and nutrition plan was implemented for the police trainees during their professional postgraduate education at the Abu Dhabi Police College. The physical training program consisted of 12 hours per week during the first six weeks and nine hours per week during the second six weeks. The nutritional plan consisted of six weeks in controlled caloric conditions (caloric deficit 500 Kcal) and six weeks in partially controlled conditions (no insights on food intake over the weekend). A body composition analyser (InBody 370) measured body mass index (BMI), body fat percentage (PBF), and skeletal muscle mass percentage (PSSM). A paired sample T-test, and effect size (Cohen’s d) with percentage differences (%) were used to evaluate the training effects and magnitude of training and nutrition plan changes. Significance was set at p = 0.05 a priori.Results:At the end of the 12-week program trainees significantly reduced BM (t(54) = 24.77, p < 0.001, d = 3.34, 11.45%), BMI (t(54) = 23.28, p < 0.001, d = 3.14, 11.68 %) and PBF (t(54) = 22.53, p < 0.001, d = 3.04, 20.70%), while significantly increased the PSMM (t(54) = 21.98, p = 0.001, d = 2.96, 9.88%).Conclusion:A dedicated 12-week physical training program with a caloric controlled nutritional plan can lead to significant improvements in the body composition of overweight police trainees and reduce their associated health risks.
