In this study, we aimed to assess the maximal oxygen uptake (VO) of young, healthy, non-athletic Saudi men using maximum graded exercise with instant breath-by-breath analysis and to compare this value to the predicted VO by international formulae. In this cross-sectional study, 88 young non-athletic normal-weight Saudi subjects were recruited from Eastern Province of Saudi Arabia with mean age (21.3 ± 1.5 years), weight: (64.7 ± 7.5 kg), height: (172.3 ± 6.1 cm) and body mass index: (21.8 ± 2.1). All subjects were interviewed and examined for eligibility, after which they performed maximum graded exercise testing on a treadmill to obtain VO. The predicted VO was also generated using the following formulae (Edvardsen, Fairbarns, FRIENDS, Hansen, and Jones). The mean measured VO was 41.9 ± 7.2 ml/kg/min. While the predicted VO using the formulae were: Edvardsen = 66.8 ± 7.9, Fairbarns = 64.1 ± 4.7, FRIENDS = 53.5 ± 2.2, Hansen = 42.8 ± 0.54, and Jones = 50.9 ± 5.1 ml/kg/min. There was a significant difference between all the predicted VO and the measured one using the paired t-test (P < 0.001), except for the Hansen's predicted value (P = 0.212). The effect size index (Cohen's d) for the comparison of Hansen's VO and measured VO was trivial and equal to 0.13. The Bland-Altman test showed good agreement between the measured and Hansen's predicted VO. This study demonstrated the mean VO value of young, healthy, and non-athletic Saudi men. This value was lower than Western values, which might be due to low physical activity or racial differences. Most international formulae overestimate the VO in this population, except for the Hansen equation. Therefore, Hansen's predicted VO might be the best available reference value for the diagnosis and prognosis of young Saudi individuals undergoing maximum exercise testing.
在这项研究中，我们旨在使用即时逐口气分析评估年轻、健康、非运动员的沙特男性的最大摄氧量（VO），并将此值与国际公式预测的 VO 进行比较。 在这项横断面研究中，从沙特阿拉伯东部省招募了 88 名年轻的非运动员正常体重的沙特受试者，平均年龄（21.3 ± 1.5 岁）、体重（64.7 ± 7.5 公斤）、身高（172.3 ± 6.1 厘米）和体重指数（21.8 ± 2.1）。 所有受试者均接受访谈和体检，以确定其是否符合条件，然后在跑步机上进行最大分级运动测试以获得 VO。 还使用以下公式（Edvardsen、Fairbarns、FRIENDS、Hansen 和 Jones）生成预测的 VO。 平均测量的 VO 为 41.9 ± 7.2 ml/kg/min。 而公式预测的 VO 分别为：Edvardsen = 66.8 ± 7.9，Fairbarns = 64.1 ± 4.7，FRIENDS = 53.5 ± 2.2，Hansen = 42.8 ± 0.54，Jones = 50.9 ± 5.1 ml/kg/min。 配对 t 检验显示所有预测的 VO 与测量的 VO 之间存在显著差异（P < 0.001），除了 Hansen 的预测值（P = 0.212）。 Hansen 的 VO 与测量的 VO 比较的效应大小指数（Cohen's d）微不足道，等于 0.13。 Bland-Altman 检验显示测量值和 Hansen 预测值之间具有良好的一致性。 这项研究显示了年轻、健康、非运动员的沙特男性的平均 VO 值。 这个值低于西方的值，这可能是由于低体力活动或种族差异。 大多数国际公式高估了该人群的 VO，除了 Hansen 方程。 因此，Hansen 的预测 VO 可能是对接受最大运动测试的年轻沙特个体进行诊断和预后的最佳参考值。
