[<< wikibooks] Exercise as it relates to Disease/Optimal exercise prescription for General Anxiety disorder
== General Anxiety Disorder ==
While it is common for most people to experience anxiety at one or more points of time in their life, this does not classify them with a General Anxiety Disorder. Those diagnosed with General Anxiety Disorder experience severe, disabling anxiety which has a prolonged negative impact on their function at work, home, school or general life.

== Symptoms ==
Each of the specific forms of anxiety disorders will have their own set of symptoms that lead to their own prognosis, however, commonly people with GAD will experience constant and chronic worry about their health, family, money, work, etc. This worry will continue every day, sometimes all day, and interfere with social activities and relationships.Alongside with these symptoms, it is common to experience the following physiological symptoms; 

Muscle tension
Difficulty sleeping
Gastrointestinal discomfort/diarrhea 

== Common Treatments ==
Treatment for GAD can be broken down into 3 different categories, psychological treatments, medical treatments and other treatments.
Psychological Treatments:
Cognitive Behaviour Therapy; A patient undergoing CBT works with a professional to analyse the ways they think and act that may be causing them anxiety.
Behaviour Therapy; While behavior therapy is a major part of CBT it differs in that it focuses completely on increasing the patient’s level of activity and pleasure in life.Medical Treatments:
Antidepressants; Antidepressants are designed to correct the imbalance of chemical messages through neurons in the brain. People do not need to be experiencing depression symptoms for antidepressants to be an effective method of controlling anxiety.
Benzodiazepines; Benzodiazepines are a form of sedative and can be used as a short-term method (two –three weeks) of reducing anxiety and assisting to cope with panic attacks. Long term used is not recommended, as they are known to be addictive.Other Treatments:
Family & Friends; Family members can offer support, understanding and help for an individual suffering from anxiety. They offer a way to keep the individual connected and feeling confident.
Exercise; Exercise can assist by lifting mood, improving sleep and increasing energy levels. It also offers opportunities to socialize and block out negative thoughts.
Diet; A good diet will generally give people a sense of well being, assisting with the individuals outlook on life. A nourishing diet can also improve mood and maintain healthy brain functioning.
Relaxation Therapy; Relaxation therapy helps to relax the muscles, which in turn may help to reduce anxious thoughts and behaviours.

== Benefits of Exercise on GAD ==
Exercise can help reduce anxiety through a number of means. Exercise allows the person to; 

Reduce tension levels
Reduce stress
Increase energy levels
Improve and regulate sleep
Feel a sense of achievement
Lower anger and frustration levels
Regulate appetite levels
Increase their social life

== Optimal Exercise ==
Persons wishing to us this alternative form of treatment for generalized anxiety disorders should undergo an exercise program under the supervision of a professional. 
An exercise program should be written incorporating 3-4 sessions per week of low to moderate intensity exercise at around 30-40% of VO2 max (light jogging, cycling, swimming etc.). 
 As well as this, leisure activities or sports are advised, particularly those involving high social interaction. These are intended to encourage socializing and to allow the person to work their way into situations that tend to bring on panic.
The program should last, with proper adherence, 3–12 weeks to take full advantage of the benefits. Programs lasting less than 3 weeks have been shown to have little to no impact on anxiety levels, while programs lasting longer than 12 weeks have shown less promising results. One explanation could be that motivation levels for programs lasting longer than 12 weeks tend to be lower. Reevaluation of the program should be made every 2–3 weeks to ensure its relevance. 
Programs involving high levels of resistance training and high intensity exercise should be avoided where possible. Studies have shown that resistance training and high intensity exercise could in fact be increasing anxiety levels and brining on panic attacks.
Meditation, in combination with exercise, has been shown to decrease overall anxiety levels in people with high anxiety. Relaxation for 20 minutes a day has been shown to have a profound impact on those suffering from anxiety. Correct technique isn’t as important as personalizing the experience to create the least stressful environment possible.

== Future Research ==
Further research is required in the field of Exercise as a treatment for Generalized Anxiety Disorders. There is a particular need for research into the difference between high intensity and low intensity exercise and the effect different forms of exercise have on anxiety levels. As well as this further research is required to provide more information about high level anxiety disorders and the effectiveness of exercise as an alternative treatment program.
