Study shows that engaging in long-term physical activity can help middle-aged and older adults lower their risk of diseases and mortality. The benefit of 行使 is regardless of previous levels of physical activity when the person was younger.
世界卫生组织指南建议每周 150 分钟中等强度 体力活动 以保持身体健康。 多项研究表明，身体活动水平与各种原因导致的疾病风险、心血管疾病、死亡和癌症风险有关。 尽管没有太多研究来了解身体活动水平的长期变化如何影响一般人群的健康。
26 月 XNUMX 日发表的一项新研究 BMJ has investigated long-term effects of being 物理 active during middle and 年龄大了. The study included data of 14,499 men and women (of ages 40 till 79 years) from the European Prospective Investigation into Cancer and Nutrition-Norfolk (EPIC-Norfolk) study conducted between 1993-1997 in the UK. All participants were analysed for risk factors at the start of the study, then three times in 8 years and every participant was followed up for additional 12.5 years. Physical activity energy expenditure (PAEE) was calculated from self-reported questionnaires and this was combined with movements and heart monitoring. The array of physical activity included first, type of work/job a person did (sedentary office, standing work or 物理 laborious tasks), and second, leisure activities like cycling, swimming or other forms of recreational activities.
在权衡体力活动和其他一般风险因素（饮食、体重、病史、血压、胆固醇等）后，分析表明，即使从中年开始增加体力活动水平也与较低的死亡风险相关。 PAEE 每年每增加 1kJ/kg/天，死亡风险（任何原因）降低 24%，心血管死亡风险降低 29%，癌症死亡风险降低 11%。 该数据与该人在年轻时或中年之前是否进行身体活动无关。 那些已经非常活跃但进一步增加活动水平的人的死亡风险降低了 46%。
目前的研究是大规模进行的，对参与者进行长期跟踪和反复监测。 研究表明，如果中老年人更加活跃，可以收获 长寿 无论过去的身体活动和既定的风险因素如何，即使他们有健康状况，也可以从中受益。 这项工作总体上支持身体活动对健康的益处，还表明在中后期保持身体活动可能是有益的。
