LEVELS AND LAYERS THE KEYS TO OLDER ADULT FITNESS Exercise and ageing specialist Sally Castell looks at the challenges – and the solutions – when it comes to training older adults. hen we’re young we can – and do – challenge our bodies, but over time the body (and mind!) can start challenging us. Ultimately, a fulfilling, quality life is everyone’s goal, whatever their age. So how can fitness professionals help this be achieved? As we know, effective exercise interventions can reduce, and prevent any unnecessary, health problems. Your community – which includes older adults and the less able – needs your expertise, energy and vision to support, encourage and equip people to both become and remain physically active and independent throughout life. W The aged population is booming The fastest growing population is that of the older adult, with the majority living well and independently in their own homes. This population is getting increasingly ‘top heavy’. At the last census, 6 million people were aged between 50 and 89 years. Demographic trends over the next three decades project that the global number of adults aged 65 years and older will double to around two billion by 2050. This will have a huge impact on the health care system. It is imperative, therefore, that we find preventative ways to manage the wellbeing of these older adults in order to slow the escalating costs of managing chronic diseases. Age need not be a barrier to participation in physical activity. Many older people take part in exercise regimes that are appropriate to their health status and fitness capabilities. Everyone wants to be independent and retain control of their lives – and the ability to remain active is key to this. Older adults need sufficient energy, adequate strength, balance and functional mobility to maintain body control. Physical activity programs combining aerobic, strength and flexibility (and balance) components can protect against the physical and cognitive decline associated with ageing. As we age, numerous situations can become a challenge and require greater effort, both physically and mentally. Arthritis, for example, can limit movement and make many general activities painful and harder to perform. It affects a large percentage of the population, with over 3 million adults affected. Australia has some of the highest statistics on a global scale for knee and hip replacements. A 2016 article in the Gerontologist journal 1 describing the processes of healthy ageing reported that involvement in physical activities demonstrated reduced rates of chronic disease, and provided more productive older years with greater cognitive and functional capacities to carry out tasks and to participate in and enjoy social and cultural life 2 . The negative consequences of ageing and reduced physical activity Fitness and health declines with age and may eventually fall below the level required to be able to undertake everyday activities easily and safely. Physical and cognitive dysfunction are the major factors contributing to this. Inactivity is associated with a 400% increased risk of disability in activities of daily living; a 300% increased risk of balance disorders and increased risk of fall-related injuries; and a 200% increased risk of gait abnormalities. Considering these statistics, it is perhaps unsurprising that a person’s capacity to exercise decreases with age, but evidence is growing that appropriate amounts of regular activity throughout life lessens this decline. Activity limitations in later life Causes of the activity limitations common in ageing include: • physiological changes, such as musculo- skeletal (sarcopenia), neuromuscular, neurological and metabolic issues • multiple chronic conditions, such as osteoarthritis, osteoporosis (osteopenia), Parkinson’s disease, diabetes and heart disease NETWORK WINTER 2018 | 65
