The United States Marines Corps (USMC) have installed a Physical Fitness Test (PFT) to measure physical fitness levels and a Combat Fitness Test (CFT) to assess a Marine's functional fitness as it relates to the demands of combat operations. The PFT involves three events; pull-ups/push-ups (PU), two-minute abdominal crunches/sit-ups (AC), and a timed three-mile run (RUN). The CFT also involves three events; Movement to Contact (MTC), two-minute Ammunition Lift (AL), and Maneuver-Under-Fire (MANUF). It is of interest to determine if the PFT and CFT are both necessary. As such, the purpose of this study was to determine the degree of relationships between PFT (PU, AC, RUN, and total) and CFT (MTC, AL, MANUF, and total) scores of active duty Marines. The PFT and CFT scores from 19,678 active duty enlisted USMC males (age 22.5±1.3 years, height 1.77±0.07 m, body mass 79.4±10.3 kg) were analyzed. Pearson correlation coefficients (r) were calculated between the PFT and CFT total scores as well as individual events. The PFT mean±sd scores were as follows: PU=18.0±5.0 (pull-ups), AC=111.2±9.0 (repetitions), RUN=1377.0±131.4 sec, PFT total=249.6±29.6. The CFT mean±sd scores were as follows: MTC=172.5±16.3 sec, AL=113.2±10.4 repetitions, MANUF=138.3±17.2 sec, CFT total=271.6±25.6. Moderate significant (p<0.01) correlations were found between: the PFT total and MTC (r=-0.47), PFT total and MANUF (r=-0.42), PFT total and CFT total (r=0.50), RUN and MTC (r=0.46), RUN and CFT total (r=-0.43), & PU and CFT total (r=0.41). Other correlations between variables yielded "no to low" association but were also significant due to the large sample size. Within the parameters of this study, PFT and CFT event scores demonstrated no to moderate correlations suggesting that different fitness characteristics are being assessed and supports the need for both the PFT and CFT assessments.
美国海军陆战队(USMC)设立了体能测试(PFT)来衡量体能水平,并设立了战斗体能测试(CFT)来评估海军陆战队员与作战行动需求相关的功能性体能。体能测试包括三项内容:引体向上/俯卧撑(PU)、两分钟仰卧起坐(AC)以及三英里定时跑(RUN)。战斗体能测试也包括三项内容:接敌运动(MTC)、两分钟弹药搬运(AL)以及火力下机动(MANUF)。确定体能测试和战斗体能测试是否都有必要很有意义。因此,本研究的目的是确定现役海军陆战队员的体能测试(PU、AC、RUN和总分)与战斗体能测试(MTC、AL、MANUF和总分)分数之间的关联程度。分析了19678名现役美国海军陆战队男性士兵(年龄22.5±1.3岁,身高1.77±0.07米,体重79.4±10.3千克)的体能测试和战斗体能测试分数。计算了体能测试和战斗体能测试总分以及各项内容之间的皮尔逊相关系数(r)。体能测试的平均±标准差分数如下:PU = 18.0±5.0(引体向上),AC = 111.2±9.0(次数),RUN = 1377.0±131.4秒,体能测试总分 = 249.6±29.6。战斗体能测试的平均±标准差分数如下:MTC = 172.5±16.3秒,AL = 113.2±10.4次,MANUF = 138.3±17.2秒,战斗体能测试总分 = 271.6±25.6。在以下各项之间发现了中度显著(p<0.01)的相关性:体能测试总分与接敌运动(r = -0.47)、体能测试总分与火力下机动(r = -0.42)、体能测试总分与战斗体能测试总分(r = 0.50)、跑步与接敌运动(r = 0.46)、跑步与战斗体能测试总分(r = -0.43)以及引体向上与战斗体能测试总分(r = 0.41)。变量之间的其他相关性显示为“无至低”关联,但由于样本量较大也具有显著性。在本研究的参数范围内,体能测试和战斗体能测试项目分数显示出无至中度的相关性,这表明正在评估不同的体能特征,并支持同时进行体能测试和战斗体能测试评估的必要性。
