| 2 | Relationship Between Metabolic Fitness and Performance in Police Occupational Tasks显示文摘Purpose To determine the relationship between metabolic fitness test scores and performance in police occupational tasks.Methods Retrospective data from 106 law enforcement officers who completed two metabolic fitness assessments[anaerobic:a 20-m (10-m and 20-m splits) sprint,aerobic:20 m Multi-Stage Fitness Test (20 m-MSFT)]and three routine occupational tasks[1.22 m Fence jump (FJ),8.5 m Victim Drag (VD with 102.3 kg) and 'Get-up' (GU)]were collected.A Person's cor-relation coefficient and a standard multiple regression were used to assess the relationship between and predictive ability of,respectively,the fitness tests scores and performance on occupational tasks.Results There was a significant positive correlation between the 10-m sprint scores and FJ (r=0.524,P<0.001),VD(r =0.528,P < 0.001) and GU (r=0.486,P < 0.001).Similarly,the 20-m sprint scores were significantly and moderately correlated with FJ (r=0.573,P < 0.001),VD (r=0.603,P < 0.001) and GU (r=0.533,P < 0.001).These anaerobic tests' scores predicted approximately 40% of the performance in the occupational tasks analysed.The MSFT fitness assessment had a small,albeit significant negative correlation with the three tasks:FJ (r=-0.360,P< 0.001),VD (r=-0.266,P=0.012)and GU (r=-0.375,P< 0.001).Conclusion High levels of metabolic fitness correlated with faster performance in police officer occupational tasks,particu-larly ones of an anaerobic nature (i.e.the maximal sprint tests).In addition to typical aerobic fitness conditioning,anaerobic fitness conditioning could be vital for optimal performance in physically demanding tasks required of police officer. | Elisa F.D.Canetti J.Jay Dawes Phoebe H.Drysdale Robert Lockie Charlie Kornhauser Ryan Holmes Ben Schram Robin M.Orr | 2021 | Journal of Science in Sport and Exercise2021，3，2： | 0 |
| 3 | Associations Between Two Measures of Trunk Muscular Endurance Among Male Law Enforcement Officers显示文摘Purpose The purpose of this study was to explore the relationship between two measures of trunk muscular endurance.Methods Retrospective data for 520 male law enforcement officers(age 40.16±7.71 years;height=1.81±0.07 m;body mass=94.4±15.01 kg)belonging to a single US based law enforcement agency were used for this analysis.The data provided included:age,height,body mass,sit-up repetitions completed in 1-min(SU)and time to completion for the isometric prone plank(IPP).A Pearson’s product correlation coefficient was used to determine the relationships between the SU and IPP.Results Significant(P<0.001)moderate(r=0.594,R^(2)=0.352)relationships were discovered between the SU and IPP.Conclusion Based on the results of this study it appears that both the SU and IPP tests are appropriate for evaluating trunk muscular endurance,but measure separate qualities(i.e.,dynamic and static muscular endurance). | J.Jay Dawes Cody A.Stahl Robert G.Lockie Jan E.Redmond Charles L.Kornhauser Ryan J.Holmes Robin M.Orr | 2021 | Journal of Science in Sport and Exercise2021，3，4： | 0 |
