Lockie, RG, Dawes, JJ, Dulla, JM, Orr, RM, and Hernandez, E. Physical fitness, sex considerations, and academy graduation for law enforcement recruits. J Strength Cond Res 34(12): 3356-3363, 2020-This study investigated the influence of fitness on academy graduation, and any between-sex differences, in law enforcement recruits. Data collected at the start of 4 training academies were retrospectively analyzed, including age, height, and body mass; waist circumference; waist-to-hip ratio; grip strength; vertical jump (VJ); 75-yard pursuit run; 2-kg medicine ball throw (MBT); push-ups, sit-ups, and arm ergometer revolutions in 60 seconds; and 20-m multistage fitness test (20MSFT) shuttles. Recruits were categorized into graduated (GRAD = 269) and separated (did not graduate; SEP = 42) groups. SEP recruits were not split according to separation reasons, just whether they did or not. This categorization also occurred for male subjects (GRAD = 228; SEP = 32) and female subjects (GRAD = 41; SEP = 10). Independent samples t-tests calculated between-group differences for all recruits combined, male subjects, and female subjects. Correlations and stepwise linear regression calculated relationships between the data and graduation. The t-test (p ≤ 0.016) and correlation (r = ±0.137-0.296; p < 0.05) data indicated that SEP recruits (both sexes combined) were older and performed poorer in every fitness test except grip strength and VJ. SEP male subjects were older and performed poorer in all tests except grip strength (p ≤ 0.009). SEP female subjects scored lower in the arm ergometer (p = 0.008). The regression equation for all recruits found that age, 20MSFT (aerobic fitness), MBT (upper-body power), and arm ergometer (upper-body endurance) were academy graduation predictors (r = 0.169; p < 0.001). For the male recruits, the predictors were age, MBT, and 20MSFT (r = 0.182; p ≤ 0.001), and for female recruits, arm ergometer and 20MSFT (r = 0.213; p ≤ 0.003). Recruits should improve multiple fitness aspects, including muscular endurance, power, and aerobic fitness, to enhance graduation potential.
洛基、RG、道斯、JJ、杜拉、JM、奥尔、RM和埃尔南德斯、E。执法新兵的体能、性别因素与警校毕业情况。《力量与体能研究杂志》34(12): 3356 - 3363，2020年——本研究调查了体能对执法新兵警校毕业情况的影响以及性别差异。对4所警校开学时收集的数据进行回顾性分析，包括年龄、身高、体重；腰围；腰臀比；握力；垂直纵跳（VJ）；75码追逐跑；2公斤药球投掷（MBT）；俯卧撑、仰卧起坐以及60秒内手臂测力计旋转次数；20米多级体能测试（20MSFT）往返跑。新兵被分为毕业组（GRAD = 269）和分流组（未毕业；SEP = 42）。SEP组新兵未按分流原因细分，仅区分是否毕业。男性受试者（GRAD = 228；SEP = 32）和女性受试者（GRAD = 41；SEP = 10）也进行了这样的分类。对所有新兵、男性受试者和女性受试者进行独立样本t检验以计算组间差异。计算数据与毕业情况之间的相关性和逐步线性回归。t检验（p≤0.016）和相关性（r = ±0.137 - 0.296；p < 0.05）数据表明，SEP组新兵（男女合计）年龄更大，除握力和VJ外，在每项体能测试中表现更差。SEP组男性受试者年龄更大，除握力外，在所有测试中表现更差（p≤0.009）。SEP组女性受试者在手臂测力计测试中得分更低（p = 0.008）。对所有新兵的回归方程发现，年龄、20MSFT（有氧体能）、MBT（上身力量）和手臂测力计（上身耐力）是警校毕业的预测因素（r = 0.169；p < 0.001）。对于男性新兵，预测因素是年龄、MBT和20MSFT（r = 0.182；p≤0.001），对于女性新兵，预测因素是手臂测力计和20MSFT（r = 0.213；p≤0.003）。新兵应在多个体能方面进行提升，包括肌肉耐力、力量和有氧体能，以提高毕业的可能性。
