背景：增加体力活动对高血压和相关疾病患者的健康有益。目前全科医生推荐的健身房运动增加了身体活动，但荟萃分析显示，虽然这些是有效的，但由于患者无法随着时间的推移保持活动水平，绝对健康风险降低的幅度很小。本研究评估了两个以运动为导向的干预措施，旨在弥合意图行为差距，从而增加持续增加体力活动的可能性的有效性。方法/设计：四臂随机对照试验。该研究测试了两种类型的干预措施，旨在增加目前不活跃的18至74岁高血压或正常高血压患者的身体活动。这项研究将评估为期12周的体育锻炼计划的有效性，网络提供的自助工具的有效性，以促进和支持体育参与和健康行为的改变，以及这些干预措施的组合效果。对照组将是标准护理全科医生转介的健身房为基础的运动。将采用区组随机化分配受试者。第一作者和主要分析员对受试者分配不知情。主要结局指标将是在干预开始后1年使用国际体力活动问卷（International Physical Activity Questionnaire）以每周代谢当量分钟数评估的体力活动时间。次要结果包括增加参与体育活动和生物医学健康的结果，包括身体质量指数的变化，腰部和臀部的测量和血压降低。讨论：如果被证明是上级全科医生转介健身房为基础的运动，这些以运动为导向的干预措施将构成低成本的替代品。下一阶段将是对干预措施进行全面的经济评价。
Background: Increasing physical activity is known to have health benefits for people with hypertension and related conditions. Current general practitioner referrals for gym-based exercise increase physical activity but meta-analyses show that while these are effective the absolute health risk reduction is small due to patients failing to maintain activity levels over time. This study assesses the effectiveness of two sports-oriented interventions that are intended to bridge the intention-behaviour gap and thus increase the likelihood of sustained increases in physical activity.Methods/design: Four-arm randomised controlled trial. The study tests two types of intervention that are intended to increase physical activity among currently inactive 18 to 74-year-old people with hypertension or high-normal blood pressure. This study will assess the effectiveness of a 12-week sports-oriented exercise programme, the efficacy of a web-delivered self-help tool to promote and support sports participation and healthy behaviour change and the effect of these interventions in combination. The control arm will be a standard care general practitioner referral for gym-based exercise. Participants will be allocated using block randomisation. The first author and primary analyst is blinded to participant allocation. The primary outcome measures will be time spent in physical activity assessed in metabolic equivalent minutes per week using the International Physical Activity Questionnaire 1 year after commencement of the intervention. Secondary outcomes include increased involvement in sporting activity and biomedical health outcomes including change in body mass index, and waist and hip measurement and reductions in blood pressure.Discussion: If proven to be superior to general practitioner referrals for gym-based exercise, these sports-oriented interventions would constitute low-cost alternatives. The next stage would be a full economic evaluation of the interventions.
