The aim of the study was to describe the physical activity and physical fitness profile of the population of Northern Ireland and to explore the relationship between physical activity and physical fitness. This was a cross sectional population study using a two stage probability sample of the adult population of Northern Ireland (aged 16+). The main outcome measures were physical activity profile based on computer assisted interview. Physical fitness using estimation of VO2max by extrapolation from submaximal oxygen uptake while walking on a motor driven treadmill. We found that males were more vigorously active than females (M 21%:F 6%) with a steep gradient of decreasing activity with age: 49% (M 52%:F 46%) were regularly active up to at least moderate intensity. Males (mean predicted VO2max 44.4 mls/kg/min; 16-74 years) were fitter than females (mean predicted VO2max 34.0 mls/kg/min; 16-74 years) and while there was a decline in predicted VO2max with age, there was wide variation within each age category. There was no statistically significant relationship between current or past activity and fitness after adjustment for possible confounding factors, with the exception of a relationship between fitness and activity in males so that the difference between no activity and habitual vigorous activity in predicted VO2max was 4.4mls/kg/min (10.1%).
该研究的目的是描述北爱尔兰人群的身体活动和体能状况，并探讨身体活动与体能之间的关系。这是一项横断面人群研究，采用两阶段概率抽样法对北爱尔兰成年人群（16岁及以上）进行抽样。主要结局指标是基于计算机辅助访谈的身体活动状况。体能则通过在电动跑步机上行走时，根据次最大摄氧量外推法估算最大摄氧量（VO2max）来评估。我们发现，男性比女性的身体活动更为活跃（男性为21%，女性为6%），且随着年龄增长，活动量呈急剧下降趋势：49%（男性为52%，女性为46%）的人至少进行中等强度的定期活动。男性（平均预测VO2max为44.4毫升/千克/分钟；年龄16 - 74岁）的体能优于女性（平均预测VO2max为34.0毫升/千克/分钟；年龄16 - 74岁），虽然预测的VO2max会随着年龄下降，但每个年龄组内都存在很大差异。在对可能的混杂因素进行调整后，当前或过去的活动与体能之间没有统计学上的显著关系，但男性的体能与活动之间存在一种关系，即预测的VO2max中，不活动与习惯性剧烈活动之间的差异为4.4毫升/千克/分钟（10.1%）。
