Evidence overwhelmingly supports the role of exercise as a critical component in managing frailty and promoting healthy aging. Regular physical activity can improve health outcomes, enhance quality of life, and mitigate the risks associated with frailty. As public health initiatives evolve, encouraging older adults to engage in consistent and varied physical activity will be paramount for promoting longevity and well-being.

Exercise programs should be tailored to the individual's capabilities, preferences, and existing health conditions to promote adherence and safety. For frail individuals, supervised exercise programs can ensure safety and provide motivation. Involvement in community groups can help enhance social support. Addressing barriers such as fear of falling, lack of motivation, or physical limitations is essential. Educating older adults about the benefits and modifying exercises to suit their needs can help overcome these challenges.

Numerous systematic reviews and meta-analyses confirm that exercise interventions significantly improve physical performance, mobility, and quality of life in frail older adults. Research indicates that older adults who engage in regular physical activity have lower rates of frailty development and related adverse outcomes. Initiatives aimed at increasing physical activity among older adults, such as group exercises and community-based physical activity programs, have shown promising results in reducing frailty prevalence.

Incorporating weights or resistance bands to build muscle strength is vital. Guidelines typically recommend at least two days per week. Activities such as walking, swimming, or cycling can improve cardiovascular health and endurance. The recommendation is at least 150 minutes of moderate-intensity aerobic exercise per week. Stretching, yoga, and tai chi can improve flexibility, balance, and coordination, crucial for fall prevention. Combining different types of exercises in a well-rounded program is effective in addressing various aspects of frailty.

Exercise enhances muscle strength, endurance, balance, and overall functional capacity in older adults. Resistance training, in particular, has been shown to be effective in counteracting muscle loss (sarcopenia) associated with aging. Regular physical activity strengthens the body's ability to withstand illnesses and stress. This is crucial for frail older adults who may be more susceptible to health challenges. Exercise has a positive impact on cognitive functioning, delaying cognitive decline and reducing the risk of conditions such as dementia. Physical activity promotes neurogenesis and enhances brain plasticity.Exercise can alleviate symptoms of anxiety and depression, which are common in frail individuals. The social aspect of group exercise can also provide emotional support and reduce feelings of isolation. Maintaining a healthy weight is crucial for reducing the risk of frailty. Exercise helps in managing body composition, promoting lean muscle mass, and decreasing fat mass. Activities such as tai chi, yoga, and balance training are beneficial for reducing the risk of falls, which are a significant concern in frail older adults.

There’s a link between walking speed and ageing well. Here’s how you can improve your pace

"For decades, we have known that the way you walk, in particular your walking speed, is tied to your health. One study has even proposed that it be considered a vital sign, much like heart rate and blood pressure.

Various studies have found a link between low walking speed in adults over 65 and a greater risk of cognitive impairment, cardiovascular disease, falls (which could lead to fractures), hospitalisation, and even an increased overall mortality rate.

A higher walking speed, on the other hand, is associated with increased functional capacity, meaning a better ability to move around and do activities independently. It is also linked to greater longevity..."

Multicomponent exercise interventions those combining strength, balance, flexibility, and aerobic training have consistently shown the most promise in reducing frailty among older adults. Among these, the Otago Exercise Programme (OEP) has demonstrated significant effectiveness. Originally developed to prevent falls, OEP includes progressive strength and balance training tailored to older individuals and delivered in a home-based format, making it highly adaptable and sustainable.

Our recent publication contributes to this growing body of evidence. In the study titled "Effectiveness of the Otago Exercise Programme in Enhancing Balance and Strength in stroke survivors in Sri Lanka", the findings supported the programme’s role in improving lower limb strength and postural stability in a South Asian context, offering culturally relevant evidence for practice.

2. Exercise has a profound impact on several age-related conditions that contribute to frailty.

• Sarcopenia: Resistance and strength training are the cornerstone of managing sarcopenia. Regular exercise increases muscle mass, strength, and function, directly mitigating frailty progression.
• Cognitive decline: Aerobic exercise, along with coordination and dual-task exercises, enhances cerebral perfusion, neuroplasticity, and executive function, delaying or improving mild cognitive impairments.

3. Yes, several barriers and facilitators impact the uptake and adherence to exercise interventions among frail older adults.

• Fear of falling or injury
• Limited mobility or comorbidities
• Low motivation or depression
• Lack of access to trained facilitators or exercise spaces
• Cultural beliefs about aging and rest

Facilitators:

• Home-based programmes like the OEP
• Personalized and progressively challenging routines
• Social support from family or caregivers
• Education and health professional encouragement
• Positive prior experiences with physical activity
