Abstract：
Despite the well-known benefits of physical activity, less than half of adults aged 55-75 years participate in sufficient physical activity. Short bouts of vigorous intermittent lifestyle physical activity (VILPA) accumulated throughout the day can contribute toward the recommended volume of physical activity. A rich characterization of the barriers and facilitators to participation in VILPA is needed to develop targeted interventions. This scoping review aimed to identify barriers and facilitators to participation in different components of VILPA in adults aged 55-75 years, and to map barriers and facilitators to the Theoretical Domains Framework. Within the 18 eligible studies, the most prevalent barriers were related to a person\'s skills, environmental context, and social influences. Most facilitators were related to a person\'s goals, social influences, and environmental context. Interventions to promote VILPA should test the effectiveness of behavioral change measures related to the unique barriers and facilitators in this age group.
摘要：
尽管体育活动有众所周知的好处，不到一半的55-75岁的成年人参加足够的体力活动。全天积累的短暂剧烈的间歇性生活方式体力活动（VILPA）可以有助于推荐的体力活动量。需要对参与VILPA的障碍和促进者进行丰富的描述，以制定有针对性的干预措施。这项范围审查旨在确定55-75岁成年人参与VILPA不同组成部分的障碍和促进者，并将障碍和推动者映射到理论领域框架。在18项符合条件的研究中，最普遍的障碍与一个人的技能有关，环境背景，和社会影响。大多数主持人都与一个人的目标有关，社会影响,和环境背景。促进VILPA的干预措施应测试与该年龄段的独特障碍和促进者相关的行为改变措施的有效性。
