Personnel of the Danish Armed Forces must complete a yearly basic physical fitness test consisting of a Cooper's 12-min run test (CRT) and four strength-related bodyweight exercises. However, there is no validated alternative to the CRT allowing injured or sailing personnel to conduct the yearly basic physical fitness test. Therefore, the aim of this study was to validate performance in a 6-min rowing ergometer test (6MRT) against CRT performance. Thirty-one individuals (M/F: 20/11, age: 34 ± 12 years) employed at the Danish Armed Forces completed testing on two independent days; (I) the CRT on an outdoor track and (II) a 6MRT with pulmonary measurements of breath-by-breath oxygen uptake. In addition, 5 participants (M/F: 4/1, age: 40 ± 10 years) completed re-testing of the 6MRT. No difference was observed between VO estimated from the CRT and measured during the 6MRT. Absolute VO correlated strongly (r = 0.95; < 0.001) to performance in the 6MRT, and moderately (r = 0.80; < 0.001) to performance in the CRT. Bodyweight (BW) and fat free mass (FFM) correlated stronger to performance in the 6MRT compared to the CRT. 6MRT re-testing yielded similar performance results. The 6MRT is a valid and reliable alternative to the CRT, allowing injured or sailing personnel of the Danish Armed Forces to complete the basic physical fitness test as required, albeit 6MRT performance demands must be made relative to bodyweight.
丹麦武装部队人员必须每年完成一次基本体能测试，包括库珀 12 分钟跑步测试（CRT）和四项与力量有关的体重练习。然而，对于受伤或航海人员来说，没有经过验证的 CRT 替代方案可以进行年度基本体能测试。因此，本研究的目的是验证 6 分钟划船测功仪测试（6MRT）与 CRT 性能的相关性。31 名在丹麦武装部队工作的人员在两天内独立完成了测试；（I）在户外跑道上进行 CRT，（II）在带有呼吸到呼吸氧气摄取量的肺测量的 6MRT 上进行测试。此外，5 名参与者（M/F：4/1，年龄：40 ± 10 岁）完成了 6MRT 的重新测试。从 CRT 估计的 VO 与 6MRT 期间测量的 VO 之间没有差异。绝对 VO 与 6MRT 中的表现呈强相关（r = 0.95；<0.001），与 CRT 中的表现呈中度相关（r = 0.80；<0.001）。体重（BW）和去脂体重（FFM）与 6MRT 的表现相关性强于 CRT。6MRT 的重新测试产生了类似的表现结果。6MRT 是 CRT 的有效且可靠的替代方案，允许受伤或航海的丹麦武装部队人员按照要求完成基本体能测试，尽管 6MRT 的性能要求必须相对于体重进行调整。
