Exercise For Independence: A Guest Post with Siel Bleu

White Paper logo

As a junior doctor, my passion lies in the area of preventive medicine – by this I mean looking at how our lifestyles (in particular our diet, physical activity, stress management and sleep) affect our health. Most importantly, it means learning about and researching how we can optimise these lifestyle factors to optimise our health and well-being – and ideally prevent many of the chronic diseases so common in our Western society today (e.g. chronic obstructive lung disease, ischaemic heart disease, cancer and type 2 diabetes mellitus for example). When I was asked by Siel Bleu to write about the benefits of exercise for chronic disease prevention and treatment, I of course jumped at the chance! I love seeing and reading about the valuable work that Siel Bleu do, providing life enhancing exercise programmes to older adults and patient groups, and I am very proud to be asked to write for their lovely website.


Physical activity is perhaps the most important lifestyle factor I try to address with patients, family, friends and the public following I have from my blog and social media. Why? Well, I’ve got two key reasons:

  • Physical inactivity has reached pandemic levels in recent decades worldwide (1), and Ireland is no different – the 2016 Healthy Ireland Survey revealed only 32% of the Irish population were felt to be sufficiently active (2)
  • I believe that we are not doing enough to promote exercise for chronic disease prevention as well as it being a key part of the treatment of many of this conditions (by we I mean us doctors, other healthcare professionals, the general public and the wider health service), and I think a huge part of that is lack of education and awareness of the importance of regular exercise  


That’s my ‘why’ in terms of the reasons for this being important to me as a doctor. But what should be YOUR ‘why’ that motivates YOU to engage in regular physical activity? It is really essential that we believe in the treatments prescribed to us by our doctors, whether that’s a tablet to lower your blood pressure or advice to try to meet our national exercise guidelines (which many of us, both doctor and patient, are unaware of). In Ireland, broadly speaking, these guidelines (3) for adults aged 18-64, (and those aged 65+) include:

  • At least 30 minutes a day of moderate activity on 5 days a week (or 150 minutes per week), or vigorous activity 75 minutes per week (e.g. brisk walking, cycling, swimming)
  • Engage in activity which increases muscular strength and balance on at least two days per week (e.g. weight training using handheld weights or bodyweight, or yoga and tai chi)

There are many, many evidence-based physical and mental benefits of regular physical activity highlighted in this guideline, which include, and are not limited to (3):

  • Reduced risk of stroke
  • Reduced risk of heart disease
  • Reduced risk of high blood pressure
  • Reduced risk of type 2 diabetes mellitus
  • Reduced risk of colon and breast cancer
  • Reduced risk of depression
  • Improved cardio-respiratory fitness
  • Improved muscular strength
  • Improved cognitive functioning in older adults

Finally, as if that wasn’t evidence enough, I want to briefly mention a key word I’ve used in the title of this article – independence. If you had to define it, what would that mean to you? To me, in terms of health, it means the ability to live your life and care for your own physical needs without requiring the help of others. It ties in closely with our individual functional capacity. As we age, we become more frail, and a key contributor to that is the fact that our muscle mass declines each decade after the age of 30 by 3-8%, and the rate is even higher when you go past 60 (4). Loss of muscle tissue (also known as ‘sarcopenia’) negatively affects our strength, balance and ability to function independently, and as such, is a big contributor to disability in older adults. By engaging in regular physical activity, both aerobic and resistance based, whether adapted for your level of fitness or not, you are doing your very best to maintain that strength, fitness and most importantly, functional capacity, to allow you to age in as healthy and happy a way as you can.

So why not start today? Look at your day to day physical activity level, and see where and what you can improve. Sustainable changes are those that are small, achievable, realistic, and importantly, enjoyable to you – and even the smallest of changes to improve your health is better than none at all.
