Minimum age (years): 65
Maximum age (years): 74
Standard ages: OLDER_ADULT
Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: CROSSOVER
Intervention model description: Qualified participants who have signed a consent letter will be randomly assigned into three groups by a draw of lots, in a ratio of 1:1:1. The three groups will be 1) Intervention group: Resistance training (n = 40); 2) Active concurrent control group: Eight-form Yang-style Tai Chi program (n = 40); and 3) Non-treatment control group (n = 40).
Primary purpose: HEALTH_SERVICES_RESEARCH

Brief summary: Background: There is on one hand sufficient evidence showing strong association between resilience and self-rated successful aging. On the other hand, strength training could contribute the cultivation of resilience among older adults. Therefore, the current study aims to examine the effectiveness of resistance training on resilience among Chinese older adults in Hong Kong.

Methods: This study will apply a three-group, double blinded (outcome assessors and data analysts), randomized controlled trial (RCT) to examine the effectiveness of the interventions on resilience, functional fitness, and health related quality of life immediately after a 16-week intervention, as well as the residual effects 12 weeks after completion of the interventions.

Discussion: It is expected that resistance training is promising or even superior to aerobic training in the improvement of resilience. Given the limited evidence on the literature, it is urgently needed to explore the effects of resistance training on the improvement of resilience in older adults. Findings of the current study can contribute to the development of effective resistant training programs for the promotion of resilience among older adults.
