109 RESULTS: 6 weeks of IMT significantly improved T lim (p = 0.029, %Δ +29.3 ± 6.4 % IMT, -8.8 ± 11.1 %), but did not alter the change in diaphragm strength following a run to exhaustion (p > 0.05). The %Δ in P Imax from pre- to post-training was significantly correlated with the %Δ in T lim from pre- to post-training (p = 0.031, r = 0.622). No changes were observed in minute ventilation or breathing mechanics (all p > 0.05). CONCLUSIONS: IMT improves exercise tolerance with thoracic LC, but does not attenuate the severity of diaphragmatic fatigue following a running time to exhaustion test. 413 Board #234 May 31 9:30 AM - 11:00 AM Assessment of the Physical Requirements Related to the Basic Training Program in Police Patrolling Sébastien Poirier 1 , Annie Gendron 2 , Louis Laurencelle 1 , Joany Badeau 1 , Claude Lajoie 1 . 1 Université du Québec à Trois-Rivières, Trois- Rivières, QC, Canada. 2 École Nationale de Police du Québec, Nicolet, QC, Canada. (Sponsor: François Trudeau, FACSM) Email: Sebastien.Poirier@uqtr.ca (No relationships reported) PURPOSE: To evaluate the demands of the basic training program in police patrolling (BTPPP) at the École Nationale de Police du Québec in order to develop a job-related physical test (JRPT). The aims were to: 1. quantify the physiological demands of the training and 2. identify and analyze the physically demanding and critical tasks of the training. METHODS: AIM #1: To determine the physiological demands, 56 cadets were recruited (27 M, 26 F). Their VO 2max and maximal heart rate (HR max ) were directly assessed (VO 2max : 48.9 ± 6.8 mlO 2 - kg -l ·min -l ) using an incremental treadmill test. The physiological demands of the BTPPP were later quantified by recording the HR of participants during the physically demanding classes and then VO 2 was extrapolated using a personalised regression function. Video sequences were also taken during those classes to allow further analyses. AIM #2: To identify the critical tasks of the BTPPP, 12 police training-experts participated in an advisory activity in which they were asked to individually rate the critical aspect of various tasks using a seven point Likert-like scale. A ranking of the most critical physically demanding tasks was established based on the scores given by the experts. The tasks scored as the most critical were later analyzed by 4 experts in kinesiology in order to identify the physical abilities needed to execute those tasks. RESULTS: AIM #1: HR analysis showed participants spent very little (Avg. = 0.62%) of their time in class at a HR > 90 %; the most difficult classes required VO 2 averaging only 35.2 mlO 2 - kg -l ·min -l for females and 43.1 mlO 2 - kg -l ·min -l for males. AIM #2: Critical tasks identification by police training-experts allowed the creation of a rank order list of 11 tasks of which the 7 most critical were, in order: reactive shooting, wrestling, self-defence with a baton, pursuing a suspect, force open a door, crowd control, and moving an unconscious person. Analysis of these 11 tasks by experts in kinesiology allowed the ranking of the most essential physical abilities, the first four being lower body power, coordination, upper body power and agility. CONCLUSION: The assessment of the physical demands of the BTPPP allowed the creation of a JRPT based on the proper abilities and tuned to the energy expenditure and critical physically demanding tasks taught during the training. 414 Board #235 May 31 9:30 AM - 11:00 AM Development of a New Job-Related Physical Test for the Basic Training Program in Police Patrolling Claude Lajoie 1 , Sébastien Poirier 1 , Annie Gendron 2 , Louis Laurencelle 1 . 1 UQTR, Trois-Rivieres, QC, Canada. 2 École Nationale de Police du Québec, Nicolet, QC, Canada. (Sponsor: Francois Trudeau, FACSM) Email: claude.lajoie@uqtr.ca (No relationships reported) PURPOSE: Based on previous observation and analyses of the basic training program in police patrolling, the main physical abilities required to successfully accomplish the critical and essential tasks of the program were identified. The objective of the study was then to develop and validate a new physical test for the École Nationale de Police du Québec (ENPQ) based on a job related approach sustaining the bona fide occupational requirements criteria. METHODS: Our approach focused both on job task simulation and assessment of specific motor and physiological abilities. Seventeen tasks representing the main physical abilities elicited in the training program were evaluated throughout the test circuit, especially: lower and upper limb power, upper limb strength, global coordination and agility. To validate the test, 184 male and 56 female police students were recruited. Students executed the new ENPQ test and also a series of six ‘convergent’ measur es (C): Edgren agility test (C1), dynamometer test for strength (C2), seated medicine ball throw for upper body power (C3), vertical (C4) and horizontal (C5) jump tests for lower limb power, and a maximal aerobic power estimation (C6). Among the experimental group, 39 male and 9 female police students did twice the ENPQ test for establishing test- retest reliability. RESULTS: The new ENPQ test consists of a time circuit including various tasks in continuity, separated by 3 laps: lap 1 (8 tasks), lap 2 (7 tasks) and lap 3 (7 tasks). Mean completion time was significantly different (p<0.001) between male (210 ± 25 sec) and female participants (282 ± 52 sec). Correlation between the ENPQ test time and the six convergent tests were all significant (p<0.01) and moderately high: C1 (r=-0.43), C2 (r=-0.62), C3 (r=-0.59), C4 (r=-0.50), C5 (r=-0.71) and C6 (r=-0.49). Test-retest reliability (n=48) was r=0.81. CONCLUSION: The construction design used for the development of the new test insures per se its content (face) validity. On the other hand, the correlations obtained between the independent six ‘convergent’ ability measures and the new test’s time performance confirm its multi-facetted concurrent validity. As for its predictive, or practical, usefulness for the tightening and betterment of the training standards of future police officers, this remains to be investigated. 415 Board #236 May 31 9:30 AM - 11:00 AM DEXA Body Composition and Cardiovascular Risk Factors are Weakly Related in Police Officers Alison McGuire, Stephen F. Crouse, FACSM, Steven Martin, Allison Donnell, Daniel Mohnke, John S. Green, FACSM. Texas A&M University, College Station, TX. (Sponsor: Dr. Stephen Crouse, FACSM) (No relationships reported) There is currently little research on whether fat mass and distribution are predictors for cardiovascular risk. PURPOSE: To determine if obesity measures, such as fat mass and distribution (e.g. android vs gynoid), could be used to predict cardiovascular risk, particularly lipid levels, systolic blood pressure (SBP) and blood glucose. METHODS: 182 police officers (166 males, 16 females; age 37.6±8.1 yrs; ht 1.7±0.1 m; wt 92.2±17.8 kg; BMI 28.9±4.8) were part of an annual cardiovascular risk profile testing group. We measured resting blood pressure and body composition via DEXA scan (SBP 127.16±10.33 mmHg; fat mass 26.85±9.99 kg; lean mass 62.01±9.90 kg; percent android fat 35.5±10.1; percent gynoid fat 29.7±6.9). Fasting blood samples were drawn and analyzed by a clinically certified lab to determine total blood cholesterol (TC) (192±37 mg/dL), LDL (119±35 mg/dL), HDL (46±10 mg/dL), triglycerides (129±99 mg/dL), and glucose (87±19 mg/dL). Correlations were determined by using a bivariate Pearson correlation matrix, significance was set at and p<0.01**. Copyright © 2017 by the American College of Sports Medicine.
