Physical inactivity in older adults is associated with declining functional capacity, sarcopenia, metabolic changes, and cognitive changes. Current Physical Activity Guidelines recommend 150 min of moderate-intensity exercise along with strengthening and balance exercises. Despite the guidelines there is little evidence of a population-based change in physical activity.
There is a growing body of research investigating the use of high-intensity interval training in older adult to improve health-related outcomes. Research indicates that high-intensity interval training confers greater benefit than moderate-intensity exercise and is acceptable and safe for older adults and those with various noncommunicable diseases.
A major challenge to health systems is the growing number of people surviving into older age, many of whom have more than one noncommunicable disease. Physical inactivity is a modifiable risk factor for the development of noncommunicable diseases. Increasing participation in physical activity interventions, particularly those at a high intensity, appears to be a safe and feasible approach to reducing the demand on healthcare systems into the future.
老年人身体活动不足与功能能力下降、肌肉减少症、代谢变化及认知改变相关。现行身体活动指南建议进行150分钟中等强度运动以及加强锻炼和平衡练习。尽管有这些指南,但几乎没有证据表明基于人群的身体活动有变化。
越来越多的研究在调查高强度间歇训练对改善老年人健康相关结局的作用。研究表明,高强度间歇训练比中等强度运动带来更大益处,对老年人及患有各种非传染性疾病的人来说是可接受且安全的。
卫生系统面临的一个重大挑战是活到老年的人数不断增加,其中许多人患有一种以上非传染性疾病。身体活动不足是导致非传染性疾病的一个可改变的风险因素。增加对身体活动干预的参与,尤其是高强度干预,似乎是未来减少医疗系统需求的一种安全可行的方法。
