The novel cognitive frailty construct was first defined some years ago and is characterised by the presence of both physical frailty and potentially reversible cognitive impairment in the absence of dementia.¹²⁶ The role of physical exercise interventions on cognitive function in older adults has been previously studied^112,127; however, the large variability in measured cognitive outcomes and methodological aspects of studies makes it difficult to draw conclusions about the effects of physical exercise on cognition in older adults. A recent randomised controlled trial (RCT) examined the effects of four months of low‐intensity high‐speed resistance training (i.e., muscle power training) in older adults with MCI and found that the intervention improved cognitive function and physical performance.¹²⁸ Similarly, it has been shown that four weeks of high‐speed resistance training combined with walking and balance exercises improved gait ability, balance, and muscle strength and reduced the incidence of falls in frail patients with dementia after long‐term physical restraint during nursing care.⁴ In agreement with other studies, there is a strong link between cognition and muscle strength, and physical frailty is associated with worse cognitive performance in multiple domains such as verbal memory, processing speed, and working memory in older people.^126,129 Therefore, an individualised multicomponent exercise training with special emphasis on high‐speed resistance training may be a cornerstone for frail individuals with cognitive impairment to improve their physical and cognitive function simultaneously.⁵
