REGRESSION
The REACT programme provides important evidence supporting WHO, United States, and United Kingdom PA recommendations for multimodal exercise for adults older than 65 years at risk of mobility disability (More transparent and detailed reporting of exercise interventions across a range of health conditions is essential for the future advancement of exercise knowledge and dissemination of research findings. Exercise programmes for older adults at high risk of mobility disability should be flexible and varied enough to offer progression and regression of exercise intensity/difficulty based on the energy status of the individual. These analyses will aid the development of future recommendations of good practise on how best to support older adults to maintain an active lifestyle and quality of life. Exercise-based interventions (with detailed exercise protocols provided) that utilise a similar methodological approach for frail older adults (i.e., SPPB score less than 4 (not captured by REACT)) are warranted. There is now a requirement for implementation studies evaluating the impact of REACT in a wide community role out.
