Critically Analyse the Research Findings on the Acute and Chronic Effects of Exercise on Anxiety and Depression
It has long been speculated that there is a relationship between exercise and it effects on anxiety and depression. However, it is not until recently that research has shown that exercise is associated with positive changes in mood and reductions in anxiety and depression. According to the Mental Health Victoria, depression is characterised by prolonged feelings of sadness, dejection and hopelessness and will affect one in four women and one in six men at some point in their lives. In the United States, anxiety disorders and depression are the most common mental health disorders costing the public $45 billion a year (Berger,

399). Investigations on the chronic effects of exercise have involved programs which last approximately 2-4 months consisting of two to four sessions per week. Most research on effects of acute exercise has focused on the reduction of state anxiety. Recent studies, (Focht & Hausenblas, 2001; Ekkekakis, Hall & Petruzzello, 1999) showed that aerobic exercise resulted in lowered state anxiety and higher tranquility scores. In addition to this, other research has revealed that moderate-intensity exercise produced the greatest positive effects in affective responses implying that the anxiety reduction following exercise occurs regardless of the intensity, duration or type of exercise (Berger, Pargman & Weinberg, 2002, pp. 399-401). Raglin and Morgan (1987) found that state anxiety was reduced for 24 hours after the exercise bout, whereas participants in a control rest condition returned to baseline levels within 30 minutes (Berger, Pargman & Weinberg, 2002, pp. 400). Although acute exercise is no more effective in decreasing state anxiety than quiet rest of distraction, the effects last longer. According to Breus and O’Connor (1998), the decrease in state anxiety after exercise lasted several hours, which was more than in the distraction and quiet rest groups. This implies that positive effects may be gained after a few weeks of training, but enduring effects may only be achieved through continuous exercise.
There is a need to develop
Million of Americans go through the blues and sad moments from clinical depression each year. Most patients with depression first seek treatment from a therapist or a primary care provider. However, exercise is a developmental behavior intervention that has displayed strong promise in alleviating symptoms of depression. The objective is examine whether physical activity is associated with depression in an average size population based on gender and age. A total of 310 participates ( 123 Male and 184 females and 3 other ) of UO students and other random volunteered to participate. All participants age ranged from 14 to 99, had to completed two self- report questionnaires. Besides answering question on their exercise habits during the past week, also took into account that all participants also completed CES-D questionnaire that determine their depression levels. In the surveyed there was a lower level of depression with more frequent weekly exercise give it a negative correlation. Also with the duration question, showed a significant negative correlation with the levels of depression. The efficiency of exercise in reducing depression cannot be determined because of the small size of participates and the lack of excellent quality research on population with adequate follow up

One group took part in an aerobic exercise program, another was given SSRI, (Selective Serotonin Reuptake Inhibitor) which is a used as an antidepressant in many athletes struggling to cope with pressure. The third group was to do both of the programs together. At the 16-week mark, depression had lowered in all three groups. In fact, about 60-70% of the participants could no longer be classified as having severe depression (June 2009 Harvard Medical School). The groups scores rating on levels of depression were relatively the same, this suggests that for those who need or want to avoid drugs, exercise in a suitable substitute for antidepressants. Keep in mind though, that the swiftest response occurred with the group taking antidepressants and that it can be difficult to stay motivated to exercise when you are depressed. This shows how beneficial exercise can be when trying to relieve depression in athletes and social sport participants but this is not true for elite athletes as exercise is already a massive contributor to their lives, so although that exercise can help people suffering from depression, there is clearly other severe factors that are affecting an elite athletes mental
While the research of Blumenthal et al. (2007) focused on exercise being effective in reducing self-reported depressive symptoms, Diaz and Motta (2008) and Motta, Kuligowski, and Marino (2010) looked at the positive effects of exercise on depression, anxiety and PTSD. The theory of exercise’s positive effect on mental health has heavily been focused on
Many mental disorders and diseases can be treated overtime or minimised through physical activity and exercise in studies confirmed by Norway scientists; highlighting that through a four-year study depression, anxiety cardiovascular diseases are decreased in adults that engage in regular exercise (Zshuckle, Gaudiltz and Ströhle, 2013). As research shows us, the relationship between PTSD and poor physical health is predominant in the case of fear; restricting the patient in partaking in physical
An exercise intervention could be used especially because people who are depressed feel a sense of worthlessness (as in the definition of depression, DSM-V ) . A pilot study by Nadine McGale et al (2011) investigated the effectiveness of a team-based sport with an individual exercise and a control condition of young men. This study included a 10-week randomized control trial and an 8-week post intervention follow-up. A group of 104 sedentary males (exercise once or less per week) aged between 18 and 40 years were randomly assigned to the three groups namely the team-based sport, individual exercise and the control group (that received no intervention). The participants completed the Becks Depression Inventory- 2nd
A growing epidemic in America is depression. Physicians are able to prescribe drugs to help with the symptoms of depression, but other therapeutic methods have been studied and show great results in recovery. Therapeutic Physical Fitness has shown to reduce depression and anxiety. Ihas been confirmed through experiments that physical exercise can be as effective as antidepressant drugs and some cases suggest that it better prevents symptom recurrence.
Since 1990s, many scientists agree that exercise has positive impacts on people’s physical health and mental health (SIME WE, 1987). From Morgan and O’Connor’s research, people can reduce stress and state anxiety by doing physical activities; also gain emotional pleasure from the process (Morgan and O’Connor, 1988). Later in 1997, Landers states that physical activities can reduce people depression after weeks of regular and routine exercise. In addition, people can benefit from more
In the book, Spark: The Revolutionary New Science of Exercise and The Brain by Dr. John J. Ratey, MD (2008), Ratey discuses how exercise can help treat many mood disorders and how it can help strengthen our brains. This book is divided into ten chapters all with five to ten subsections in them. The chapters include: Welcome to the revolution: A Case Study on Exercise and the brain, Learning, Stress, Anxiety, Depression, Attention Deficit, Addiction, Hormonal Changers, Aging, and the Regimen.
According to Butler et al (2008), exercises that need high energy and regular aerobic practices are likely to cut down the depression symptoms at a rapid rate. Further, the authors are of
This report aims to determine the efficacy and benefits of exercise in the management of depression, which is classified by the World Health Organisation as a mood disorder. In order to place exercise therapy into context, conventional methods for treating clinical depression are discussed. A personal meta-analysis is then undertaken, summarising the findings of studies that have explored the clinical significance of physical exercise as an intervention in treating depression. The advantages and disadvantages of such an intervention are described, and
Several studies suggest that regular exercises are related to a decreased likelihood of depressive symptoms and they are probably associated with a dose-response (3). These studies have important short-outcomes; however, most of them are cross-sectional, and because of that, it is hard to determine the temporal sequence between physical activity and depression, because only interventional studies are able to define this relationship (3). So, further research was needed to determine the bidirectional association between exercises and depression. This bidirectional association is understood by the fact of physical activity reduces the risk for depression symptoms, but these symptoms are usually related to poor levels of physical activity, and it can diminish the possibility of physical activity. It is possible that depressed patients are more sociable isolated than the control group, are less motivated to engage in exercises, and also have lower energy levels/apathy (3). Consequently, there are two main pathways: exercise improves humour and provides an efficacy and welfare which decreases the chance of developing depression; or depressed patients have a diminished chance to practice exercises because they feel unworthy and without interest. Apart from several studies defending a positive relation between physical activity
“Eleven percent of Americans aged 12 years and over, take antidepressant medication,” “antidepressants were the third most common prescription drug … in 2005 – 2008,” and from 1988 to 2008, the rate of antidepressant use in the US increased nearly 400% (Pratt).
They found that an exercise training programme could be an alternative treatment for MDD. Although antidepressants had a more rapid response than exercise, after 16 weeks of exercise the effectiveness in reducing depression was equal to the anti-depressants. A study also found that a single bout of exercise could result in substantial improvements in mood, which shows that it’s not just duration and frequency. However, it may be that the improvement in mood is only temporary (Dimeo et al., 2001). Lawler and Hopker (2001) stated that effectiveness of exercise on depression couldn’t be determined due to lack of quality research based on clinical populations. They also wrote that the explanations of the results may have been that depressed patients who did regular exercise could have got positive feedback from other people and a sense of self worth, which may act as a diversion from negative thoughts. Physical activity was found to be linked with less coexisting depression, which remains the same after controlling for gender, age, and race. The results of the study showed that physical activity is helpful with medical problems, life stressors and quality of sleep (Harris et al., 2006).
Exercise may be one of the most important influences on your overall health to date. While the only benefits that are mainly focused on are the physical benefits, significant psychological impacts can also be linked to exercise. Although some of these benefits aren’t viewed with much enthusiasm, studies have proven that exercise can actually improve one’s quality of life greatly by increasing not only their physical health but their mental health as well. It is because of this that exercise is a
