Introduction
Whether measured subjectively or objectively, a large proportion of the population
are living sedentary and physically inactive lives.1
2 This should be a major public health focus given the overwhelming evidence demonstrating
that physical inactivity increases an individual's risk for all-cause mortality and
may be one of the leading causes of non-communicable chronic disease in the world,
responsible for about 60% of worldwide deaths3–6 and probably more in developed countries.
Pandemic levels of physical inactivity result in a huge burden of unhealthy consequences
within populations and for society, across all socioeconomic classes, all ethnicities
and phenotypes.
However, attempts to explain the precise causes of chronic diseases and resultant
deaths, for each individual, are very difficult. We are all exposed to multiple risk
factors in variable quantities throughout our lives and, currently, these are virtually
impossible to measure. Consequently, despite our remarkable growth in the medical
field, explanations for precise causes of death remain speculative. To attribute causal
status of risk factors for non-communicable disease is fraught with difficulty both
clinically and medicolegally. For example, it is baffling that despite scientific
progress since Richard Doll's landmark findings 60 years ago, strongly linking smoking
with lung cancer,7 causation of smoking and lung cancer has still not been upheld
in a court of law.8
Duty of care
Duty of care is a legal obligation imposed on a doctor requiring, via the Bolam test,9
that their actions conform to those of a responsible body of professional opinion,
even if others have a different opinion. More recently, the Bolitho v City and Hackney
Health Authority case, entitled a judge to choose between two bodies of expert opinion
and reject an opinion, which is ‘logically indefensible’.10
In the UK, duty of care, in the form of National Institute for Health and Clinical
Excellence and Royal College guidelines, currently represents an evidence-based responsible
body of professional opinion relating to clinical care. Medical ethics, including
patient autonomy, non-maleficence, beneficence and informed consent, guide our medical
care, when guidelines are not always appropriately applied. Medical defence unions
providing medical indemnity repeatedly recommend that our professional and clinical
decisions be documented in medical records and note keeping, including those situations
when guidelines are not suitable.
Numerous responsible bodies of professional opinion have recognised the extensive
evidence base, cost-effectiveness and importance of physical activity promotion as
a primary prevention and secondary treatment for various diseases. Physical activity
promotion features in 39 national guidelines (table 1), even excluding physical activity–specific
guidelines. On this basis, if a doctor managing a patient with any of these diseases
has not followed these guidelines and advised or signposted appropriately on physical
activity, then it is possible that medical negligence has ensued. Furthermore, would
it be ‘logically indefensible’ for doctors not to promote physical activity for these
patients, regardless of their personal opinions and learning needs?

for the primary and secondary prevention of cardiovascular disease (CVD)
People at high risk of or with CVD should be advised to exercise 30 min a day, of
at least moderate intensity, at least 5 days a week, in line with national guidance
for the general population. People who are unable to perform moderate-intensity physical
activity at least 5 days a week because of comorbidity, medical conditions or personal
circumstances should be encouraged to exercise at their maximum safe capacity. Recommended
types of physical activity include those that can be incorporated into everyday life,
such as brisk walking, using stairs and cycling. People should be advised that bouts
of physical activity of 10 min or more accumulated throughout the day are as effective
as longer sessions. Advice about physical activity should take into account the person's
needs, preferences and circumstances. Goals should be agreed and the person should
be provided with written information about the benefits of activity and local opportunities
to be active

patients following an MI
Patients should be advised to undertake regular physical activity sufficient to increase
exercise capacity. Patients should be advised to be physically active for 20–30 min
a day to the point of slight breathlessness. Patients who are not achieving this should
be advised to increase their activity in a gradual step-by-step way, aiming to increase
their exercise capacity. They should start at a level that is comfortable, and increase
the duration and intensity as they gain fitness
10
NICE (2006, revised 2010)
Obesity: guidance on prevention, identification, assessment and management of overweight
and obesity in adults and children
Weight management programmes should include behaviour change strategies to increase
physical activity and decrease inactivity. Interventions in children should address
lifestyle within the family and social settings. If a child, family or adult are unwilling
to change, give them information about the benefits of increased physical activity,
losing weight and healthy eating. Ask about their related activity levels and beliefs

Chronic obstructive pulmonary disease (COPD): management of COPD in adults in primary
and secondary care
Pulmonary rehabilitation should be made available to all appropriate people with COPD
including those who have had a recent hospitalisation for an acute exacerbation. Pulmonary
rehabilitation should be offered to all patients who consider themselves functionally
disabled by COPD (usually MRC grade 3 and above). Pulmonary rehabilitation is not
suitable for patients who are unable to walk, have unstable angina or who have had
a recent MI. The rehabilitation process should incorporate a programme of physical
training, disease education, nutritional, psychological and behavioural intervention.
Patients should be made aware of the benefits of pulmonary rehabilitation and the
commitment required to gain these

23
NICE (2009)
Type II diabetes: the management of type II diabetes (update)
Integrate increasing physical activity into a personalised diabetes management plan
including other aspects of lifestyle modification. Measure blood pressure annually
and offer and reinforce preventive lifestyle advice. Offer lifestyle advice (diet
and exercise) at the same time for blood pressure control. Start metformin treatment
in a person who is overweight or obese (tailoring the assessment of body weight associated
risk according to ethnic group) and whose blood glucose is inadequately controlled
by lifestyle interventions (nutrition and exercise) alone. Guidance recommends trial
of 3 months lifestyle interventions to control and reduce blood glucose and HbA1c
before commencing medication

Diabetes UK (2005)
Recommendations for the provision of services in primary care for people with diabetes
If the screening test is negative and the person has no symptoms of diabetes, they
should be given advice on how to reduce their risk of going on to develop diabetes
and supported to lose weight and increase their physical activity levels. People aged
<40 with diabetes who are asymptomatic and who are overweight (body mass index (BMI)
25–30 kg/m2) or obese (BMI >30 kg/m2) should be advised to increase their physical
activity levels, adopt a balanced diet and aim to reduce their calorie intake. Insulin
should be considered in those who are not obese. People aged >40 with diabetes who
are asymptomatic should initially be treated with diet, weight control and increased
physical activity. They should be advised to increase their physical activity levels,
adopt a balanced diet and, if they are overweight or obese, aim to reduce their calorie
intake. If blood glucose control is not achieved within 3 months, treatment with oral
hypoglycaemic agents should be commenced. Insulin treatment should be considered if
blood glucose control is not achieved with diet, increased physical activity and combined
drug therapy. Oral and written information about diabetes and its management should
be provided in appropriate languages and media at each point of the care pathway as
part of a structured education programme, meeting nationally agreed criteria

Lifestyle modifications can greatly reduce the risk of ED, and should accompany any
specific pharmacotherapy or psychological therapy. The potential advantages of lifestyle
changes may be particularly pronounced in those with psychogenic ED, but patients
with serious medical illnesses such as diabetes may also benefit from these changes,
for example, weight loss (ie, diet and physical activity)

Diagnosis and management of polycystic ovary syndrome (PCOS)
An increase in physical activity is essential, preferably as part of the daily routine.
30 min/day of brisk exercise is encouraged to maintain health, but to lose weight,
or sustain weight loss, 60–90 min/day is recommended. Concurrent behavioural therapy
improves the chances of success of any method of weight loss

Falls: the assessment and prevention of falls in older people
Strength and balance training is recommended. Those most likely to benefit are older
community-dwelling people with a history of recurrent falls and/or balance and gait
deficit. A muscle-strengthening and balance programme should be offered. This should
be individually prescribed and monitored by an appropriately trained professional
Given the technology and functionality of primary care computerised medical records,
it would be relatively cheap and simple to embed such recommendations within standard
note keeping templates to help guide practitioners through the forgotten and fundamental
basis of these guidelines, ensure medicolegal defensibility, should the need arise,
and reduce the potential risk of medical-negligence proceedings.
Critics will argue that physical activity promotion is a lifestyle choice, however,
so are smoking and alcohol consumption and yet these are medically accepted risk factors
worthy of our clinical behaviour change efforts and consultation time. In many countries
around the world, exercise and tailored physical activity are used by trained Sport
and Exercise Medicine (SEM) specialists working within multidisciplinary teams, to
both treat and prevent various chronic diseases. Unfortunately, in the UK, there are
many patients with chronic diseases, risk factors and comorbidities, who are essentially
excluded from physical activity. Their attending doctors invariably lack the knowledge
to provide them with necessary physical activity and behaviour change advice (or exercise
prescription), are fearful of perceived physical activity risks and resulting litigation,
or cannot access specialist National Health Service (NHS) SEM services, despite the
existence of an emerging trained specialist SEM workforce seeking NHS employment.
Ironically, these patients stand to gain the most from intervention (as does the NHS),
yet remain unlikely to receive this advice, being advised to rest, risking further
health and well-being detriment.
The responsibility for delivering Exercise Medicine in the UK is left in the hands
of doctors who do not understand the basic science behind physical activity, benefits,
risks, doses or methods to change complex physical inactivity behaviours. Why can
we rightly refer to a dietitian for assistance with disordered eating habits and still
not refer to an SEM specialist on the NHS for specialist Exercise Medicine care, when
appropriate?
An institutional and educational problem
General Medical Council (GMC) guidance on ‘Good Medical Practice’ suggests that doctors
should ‘protect and promote the health of patients and the public’.11 Yet physical
activity promotion remains un-rewarded in primary care,6 Exercise Medicine is not
on the core curriculum of many medical schools12 and most doctors are not trained
to deliver physical activity promotion and behaviour change.
Regulatory authorities, such as the GMC, are now responsible for standards of medical
education, in a position to focus future medical practice and ensure that preventive
medicine and wellness promotion feature as highly as treatment of illness in the future.
The GMC regulates undergraduate medical education and, regrettably, physical activity
does not feature as a curricula requirement (Tomorrow's Doctors 2003 and 2009). In
addition, it is not specifically covered in GMC medical school quality assurance reviews.
The GMC, like doctors, may have a responsibility and duty of care to the public and
their future members to review medical school curricula requirements relating to the
promotion of health and prevention of disease with greater emphasis and guidance for
physical activity education. Only then, will future doctors be optimally educated
to deliver behaviour and lifestyle change for the prevention and treatment of illness,
which are embedded within ever-increasing guidelines.
UK public health strategy
In the UK NHS, the introduction of the Responsibility Deal and GP commissioning, will
probably place more health strategy decisions in the hands of corporate stakeholders
and ‘willing providers’. Hidden agendas, such as profitability, may influence important
public health rationing decisions and perceived un-profitable physical activity promotion
and Exercise Medicine may well continue to suffer. Unfortunately, very few private
stakeholders stand to benefit from better population health, which, worryingly, means
that corporate agendas could direct national health strategies and leave Exercise
Medicine largely aspirational and marginalised. In brief, for the current evidence
base to be translated into commissioned NHS Exercise Medicine services in the UK,
there is an urgent need for strong evidence to demonstrate cost-effectiveness, improved
patient care pathways and outcomes for such services.
Summary
Medical science has shown that low cardiorespiratory fitness (resulting from sedentary
behaviour) is one of, if not, the most important risk factors for all-cause mortality,13
yet clinical practice, medical education and public health strategy continue to focus
on all other risk factors except sedentary behaviour. Physical activity promotion
is embedded within a large number of ever-increasing clinical guidelines with strong
supporting evidence, both medical and cost-effective, delivering positive clinical
messages and medicolegal responsibility to healthcare practitioners.
Is it possible that there may be a time when a lawyer cross examines a doctor in the
witness stand, asking why they did not address their sick or dead patients' physical
inactivity, citing clinical guidelines, because it is known to be one of the highest
modifiable risk factors for morbidity and mortality? Physical activity promotion is
one of the first treatment recommendations in numerous clinical guidelines with a
good reason and should no longer be medically neglected.
Physical activity failings are institutionally embedded within our environment, medical
practice, education and culture. The public are being let down on physical activity
promotion, treatment choices (eg, Exercise Medicine), preventive medicine, the sedentary
environment, corporate influences, a lack of physically active medical role models
and failed by a lack of funding for physical activity and inactivity research. All
resulting in between approximately 27–59 million14 people in the UK alone, when measured
subjectively and objectively, respectively,15 literally sitting in a pre-disease or
disease state caused by physical inactivity – probably the biggest silent killer of
our times.
