Samenvatting

Previous research shows that power training can increase power output in older adults and may also improve physical performance, physical functioning, and independence. However, power training interventions have not been optimized for older adults. The aim of this study was to assess the feasibility and preliminary effectiveness of a power training program called Powerful Ageing in older adults.
A total of 28 older adults participated in a 12-week power training intervention at an intensity of 20-30% 1RM. The primary outcome, feasibility, was assessed through intervention retention, adherence (attendance and compliance), and safety. Secondary outcomes were measured in health domains of the ICF. In the function domain, muscle power and anaerobic power were assessed using a weighted squat and Wingate test, respectively. In the activities domain, physical performance was measured using the 6-minute walk test, and in the participation domain, physical activity in daily life and health status were evaluated using an accelerometer and the SF-36 questionnaire, respectively.
