This study aims to assess and compare the aerobic fitness (max VO2) of 210 healthy adult men in sedentary occupations in Singapore. All the subjects studied were in codes 0 to 2 of the Singapore Standard Occupational Classification, comprising professional, technical, administrative and related workers. Their max VO2 were determined from direct analyses of their expired respiratory gases during an all-out run on a treadmill. Of these 210 men, 71 (33.8 per cent) were recreation-related regular exercisers and their mean max VO2 of 40.9 ml/kg per min STPD (at standard temperature and pressure, dry) and 95 per cent confidence interval of 39.2-42.6 ml/kg per min was significantly higher (p less than 0.001) than that of the remaining 139 men (34.3 ml/kg per min STPD) with 95 per cent confidence intervals of 33.2-35.4 ml/kg per min who were not regular exercisers. The regular exercisers also met the max VO2 requirements for heavy physical work capacity and compared favourably with the recommended standards for aerobic fitness in the National Physical Fitness Award of Singapore as well as Cooper's Standards based on North American men while the non-regular exercisers did not. The study has shown that the recreation-related regular exercise of the study-defined type, intensity, duration and frequency can significantly improve the physical work capacity of healthy adult men in sedentary occupations in Singapore.
本研究旨在评估和比较新加坡210名从事久坐工作的健康成年男性的有氧适能（最大摄氧量）。所有研究对象均属于新加坡标准职业分类中的0至2类，包括专业人员、技术人员、行政人员及相关工作者。他们的最大摄氧量通过在跑步机上全力跑步期间对呼出气体进行直接分析来测定。在这210名男性中，71名（33.8%）是与休闲相关的定期锻炼者，他们的平均最大摄氧量为40.9毫升/千克每分钟标准温度和压力下干燥状态（STPD），95%置信区间为39.2 - 42.6毫升/千克每分钟，显著高于其余139名非定期锻炼者（34.3毫升/千克每分钟STPD），其95%置信区间为33.2 - 35.4毫升/千克每分钟。定期锻炼者还达到了重体力工作能力的最大摄氧量要求，与新加坡国家体质奖的有氧适能推荐标准以及基于北美男性的库珀标准相比表现良好，而非定期锻炼者则未达到。该研究表明，本研究定义的类型、强度、持续时间和频率的与休闲相关的定期锻炼能显著提高新加坡从事久坐工作的健康成年男性的体力工作能力。
