Introduction It is impossible to read a newspaper or turn on the television without hearing about the health benefits of physical activity. The messages have Nietzsche been clear that being active is important in terms of managing weight and preventing chronic illness (such as Type 2 diabetes). “All truly great thoughts are conceived while walking.” Despite this growing interest in the role The primary aim of this report is to ask If we are going to change our attitude to Some people may prefer to participate of physical activity in managing health that we reconsider the way that we physical activity then it needs to become in more regular and structured forms of and reducing obesity, there has been view physical activity in the UK: from a natural and important part of our lives, physical activity such as going out for relatively little corresponding change in a behaviour which we do because we not something else for us to find the a run or playing sport and these are, of people’s activity levels. National surveys ‘have to’, ‘should do’ or ‘ought to do’ time to do. For some people this will course, great ways to enhance wellbeing show that currently only one-third of the for our health, to something that we mean heading to the gym, but for others and mental health. There are so many population meet UK physical activity feel improves our lives. In other words: it may include taking the stairs at the ways to become more active, indeed the guidelines. In part, this may be a result to view physical activity ‘as a pleasure train station or department store (rather possibilities are limitless from gardening of being told that we should increase and not a chore’. Furthermore we aim than the lift or escalator) and walking through to dancing or skateboarding. our activity levels to ‘fix’ our health to make the case that physical activity or cycling to work or to the shops.

What is Wellbeing? The UK government recently defined wellbeing as ‘a positive physical and social and mental state’.1 This report focuses on mental wellbeing. The term ‘mental health problem’ is Mental wellbeing includes factors often used to describe a difficulty with such as individuals’ ability to develop our mental health that causes concern, their potential, work productively and or interrupts our ability to go about our creatively, build strong and positive daily lives in the way in which we would relationships with others and contribute want. Mental illness refers to clinically to their community’.2 p.1 It also involves identifiable illnesses or conditions that areas of life such as feelings of affect our cognitive and emotional satisfaction, optimism, self-esteem, having functioning.

What is Physical Activity? Type There are a huge number of different types of physical activity. Walking is a These different types of physical activity can have a number of different physical outcomes: An all-encompassing definition of physical type of physical activity which many people find practical and accessible; — Many types of physical activity activity is ‘any bodily movement produced it can be done at low, moderate or vigorous intensity.

The different types of physical activity are sometimes grouped under the following headings: — ‘Sport’ - structured and competitive physical activity — ‘Exercise’ - planned and purposive physical activity to improve fitness, health or performance — ‘Play’ - unstructured physical activity, done for fun and enjoyment — ‘Daily physical activity’ – physical activity which is done as part of one’s Intensity daily routine. Physical activity intensity varies along a continuum from sedentary (physically Each of these four types of physical inactive) to vigorous (high intensity activity can be done at both moderate activity). and vigorous intensity depending on what it is and how it is performed.

For example, to-day moods has been investigated people with high levels of regular in more detail; people rated their mood physical activity have been shown to immediately after periods of physical have higher levels of positive emotions activity (e.g. going for a walk or doing such as interest, excitement, enthusiasm housework) and periods of inactivity (e.g. and alertness compared to people with reading a book or watching television).8 moderate and low levels of physical Participants reported feeling more activity.6 content, more awake and calmer directly after being physically active compared to periods of inactivity.

With all the ups and downs I’ve had in my life, taking me through depression, alcohol and drug abuse, anorexia, anxiety and finally being diagnosed with bipolar in 2009, I’ve always found myself involved in some form of exercise, whether it be playing rugby, running or training in the gym.

I’m with mental illness. extremely grateful that I am able to exercise to the extent I can, as mental illness can be so utterly debilitating at times. From just a bipolar point of view, if I’m feeling high, exercise can help exhaust the nervous, uncontrollable rush of energy I would otherwise not know how to contain. If I’m feeling low, the exercise can really enhance my mood and alter my outlook on my day as a whole. 18 04 19 05

Rimer et al.24 were supervised.26 Furthermore, all prescription rates for antidepressant summarised the findings from three modes of physical activity and locations medication have increased steeply. trials that compared exercise with (e.g. home or gym) were equally However, antidepressants are not antidepressant medication, and reported effective, although it is noteworthy equally effective for all people.22 and there was no significant difference in the here that outdoor locations were many people are reluctant to take effect of the two treatment approaches not studied as these provide access antidepressants for long periods, often on depression.

4.8 Negative effects of physical activity A challenging question in this area is For the vast majority of people, physical how to distinguish healthy exercise activity is beneficial for wellbeing and from exercise dependence. Seven mental health, and these relationships diagnostic criteria have been suggested have been described above. However, to assess exercise dependence: tolerance physical activity can have a negative of increasing amounts of exercise; effect for some individuals who withdrawal symptoms from not exercising; participate in very high levels of physical lack of control over exercise; consistently activity. doing more exercise than was intended; spending a lot of time exercising; reduction Overtraining can result in a range in other activities; and continuing to of short-lived negative effects, such exercise despite physical, psychological as fatigue, low mood and irritability. and interpersonal problems.48 The Often this can be rectified by resting actual volume of exercise may be less or changing exercise patterns, such as important than the motives underlying this reducing intensity levels or altering the behaviour, and it has been suggested that type of activity to one that uses different the likelihood of an addiction increases muscle groups.46 However, overtraining for those who exercise with the goal may reflect a more unhealthy of escaping unpleasant feelings 49 or relationship with physical activity where transforming their appearance to improve there is a shift from the person choosing self-esteem as compared to those who to take part in physical activity as part of exercise with the goal of improving a healthy lifestyle, to feeling compelled performance and fitness. to take part even when the benefits are outweighed by adverse consequences.47 However, the extent to which exercise The problems that can emerge from dependence is an addictive behaviour this compulsion include planning your in its own right or is secondary to other life around exercise to the exclusion of disorders is a continuing debate.50 Eating Case Study: Jamie other domains of daily life that previously disorders are the most common disorders I was diagnosed with anxiety during a brought joy. to co-occur with exercise dependence, difficult chapter in my life.

There is accumulating evidence that walking, and physical activity more generally, can be an effective way to enhance positive moods. 028 029
How does physical activity 5.1 Physiological adaptations Many people believe that the biological explanation for experiencing enhanced Despite there still being uncertainty as to the biological reasons for enhanced mood following exercise, there have impact on wellbeing? mood and wellbeing following exercise is that exercise causes the brain to release endorphins. Endorphins are naturally been recent advances in understanding the impact of physical activity on overall brain health.

For an accessible and recent in either the blood or the brain. The review of this area see Erickson et al.54 review concludes that the hypothesis that endorphins are responsible for the changes in moods during and after exercise remains possible, but has been perpetuated based on little evidence. With developments in neuroscience and increased understanding of how the brain functions, it has become clear that changes in states of mind (such as the changes in mood that occur following exercise) will involve complex These systems act at: a interactions of many neural circuits and the release and uptake of many physiological level e.g. chemicals in the brain (e.g. acetylcholine and dopamine).53 Advances in brain influencing the release and imaging techniques are opening up new avenues for exploration, and may soon uptake of chemicals in the lead to a fuller understanding of the brain and the development biological mechanisms underpinning the relationship between exercise and of new neural pathways; mood. a psychological level e.g. influencing feelings of mastery; and a social level e.g. influencing social connections and interpersonal relationships. In this section we give a brief overview of some key mechanisms at each of these three levels. 30 31
