Our previous study suggested that the work form is related to the maximum oxygen uptake (VO(2)max). Therefore, we test the hypothesis by a longitudinal study that, besides these lifestyle-related factors, the work form increases VO(2)max among workers. Seven hundred and ninety nine males aged 37.1 ± 10.6 and 395 females aged 37.7 ± 10.5 (range: 20 to 59 yr old), who participated in The Total Health Promotion Plan (THP) at their respective workplaces twice in one year from 1997 to 1998, were selected. Data on VO(2)max were analyzed for age, systolic blood pressure (SBP), body mass index (BMI), work form (sedentary, standing, and ambulatory), exercise, and smoking. Age and the baseline variables for BMI and for VO(2)max showed significant negative relationships with a change in VO(2)max in males and females. Further, a change in the BMI showed a significant negative relationship with a change of VO(2)max in males. However, exercise habit and an ambulatory work form showed significant positive relationships with a change of VO(2)max in males. It was suggested that after adjusting for other factors in males, an ambulatory work form may be associated with an increase in VO(2)max in one year.
我们之前的研究表明，工作形式与最大摄氧量（VO2max）有关。因此，我们通过一项纵向研究来验证假设，即在这些与生活方式相关的因素之外，工作形式是否会增加工人的 VO2max。1997 年至 1998 年期间，共有 799 名年龄在 37.1 ± 10.6 岁的男性和 395 名年龄在 37.7 ± 10.5 岁的女性（年龄范围为 20 至 59 岁）参加了各自工作场所的全面健康促进计划（THP），每年两次。对 VO2max 的数据进行了分析，分析因素包括年龄、收缩压（SBP）、体重指数（BMI）、工作形式（久坐、站立和走动）、运动和吸烟。在男性和女性中，年龄以及 BMI 和 VO2max 的基线变量与 VO2max 的变化呈显著负相关。此外，BMI 的变化与男性 VO2max 的变化呈显著负相关。然而，运动习惯和走动工作形式与男性 VO2max 的变化呈显著正相关。研究结果表明，在男性中调整其他因素后，走动工作形式可能与一年内 VO2max 的增加有关。
