RE-inventing Strategies for Healthy Ageing; Recommendations and Tools (RESTART) - a Randomized Controlled Trial Testing a Complex Lifestyle Intervention in Older Adults at Increased Risk for Cardiometabolic Disease

The goal of the RESTART RCT is to examine whether a complex lifestyle intervention, coordinated with municipal and non-government organizations (NGO), can establish and preserve improvements in risk factors and functional capacity among older adults at high risk of cardiometabolic disease. The main objectives to investigate are whether a complex lifestyle intervention, compared to an active control group, will at 24 months have: 1. Produced a clinically relevant increase in cardiorespiratory fitness (primary endpoint) 2. Increased muscle strength, physical activity and reduced adiposity 3. Improved body composition, health-related quality of life and cognitive function All participants (Control and Intervention Groups) are provided with wrist-worn activity trackers at baseline and access to national recommendations on physical activity. The intervention group additionally advances through a comprehensive lifestyle program including high-intensity aerobic and strength exercise, dietary and behavioral counselling. Intervention participants are gradually transitioned into exercise activities organized by Tromsø Municipaity and local NGO:s. Testing of outcomes are performed at baseline, 6, 12 and 24 months. Primary endpoint (VO2max) is assessed at 24 months.
