Abstract/OtherAbstract:
The purpose of the study was to determine the effects of a 6-month supervised, job- specific moderate exercise program in police officers on body composition, cardiovascular and muscular fitness. Body weight (BW), body mass index (BMI), and cardiovascular and muscular fitness were assessed at baseline, after a 6-month supervised fitness program and at 12-month follow-up (18 months). One hundred sixty-five (n=131 males and n=34 females) young (mean±SEM, 26.4 ± 1.9 years), overweight (BMI=26.2±1.2 kg/m) police officers participated. Aerobic exercise progressed from 3d/week, 20 min/session at 60% of heart rate reserve (HRR) to 5d/wk, 30 min/session at 75% of HRR at 3-months and this level was maintained until 6-months. Muscular strength training progressed using 8 different calisthenics exercises from 3d/week, 2 sets of 5 repetition using the participant's own body weight to 5d/wk, 3 sets of 15 repetitions of the participant's own body weight at 3-months and this level was maintained until 6-months. Cardiovascular and muscular fitness was measured using a 0.25 mile obstacle course incorporating various job specific exercises and expressed as the physical abilities test (PAT) time. There was a significant reduction in BMI (-0.6±0.2kg/m, p<0.001) and body weight (-2.8±2.3kg) and reduction in PAT time (-11.9±2.1%, p<0.01) from baseline to 6 months. However, BMI (1.4±1.1kg/m, p<0.001) body weight (5.1 ± 3.0kg, p<0.01) and PAT time significantly increased (12.8±2.2% p<0.01) from 6 to 18 months. There were no sex by time differences. The practical applications of this study indicate that a supervised, job-specific exercise program for police officers improves fitness and body composition after 6 months in both men and women, but continued supervision of exercise program may be necessary for maintenance of health benefits.
