Lecture 12- Physical Activity and Anxiety Flashcards
Randomised controlled trial evidence- Depression
Very strong evidence for aerobic forms of PA, other modes (e.g yoga) also beneficial
Combining …. and …… “may” be optimal
Aerobic and muscle strengthening
How does PA compare to other treatments
Exercise ….
Medications
Exercise group..
Exercise is as effective as other treatments
BUT
Medication works faster
BUT
Exercise groups less likely to rep-lapse (when exercise continued)
qualitative research
Obtaining peoples experiences of PA and depression and applying rigorous analysis to understand them
Qualitative research analysis
is based on researchers interpretation of what was said requires processes to ensure bias is removed
what might be some of the challenges of promoting or using physcial activity as a means of treating depression?
-Low confidence when experiencing symptoms
-fatigue, mental exhaustion
-social withdraw and or anxiety
-Fear of failure, social evaluation
Be aware of your limitations as a practitioner
Recognise the signs and engage the help of a GP/clinical psychologist
Anxiety
State of worry, apprehension or tension that often occurs in the absence of real or obvious danger
State anxiety
Induced by situation
Trait anxiety
Occurs on a daily basis
During 2020 lockdown …..%
15.6% of NZ respondents reported moderate to high anxiety; younger adults fared worse
PA and anxiety -cohurt studies
In non-anxious people-higher levels of self reported PA associated with decreased risk of developing anxiety symptoms and anxiety disorders at least 1 year later
Anxiety and PA relationships under COVID restrictions
Those who spent -> total time in moderate to vigorous PA -> ….% lower chances of presenting anxiety symptoms
15-34%
PA interventions are effective in improving symptoms of anxiety BUT…
the quality and volume of RCT evidence is not as strong as fro depression
For anxiety was are the most effective modes of exercise
All modes effective interestingly strongest effect was for yoga, stretching and other mind body exercise
For anxiety what intensity was better
Moderate to high is better than low
Experimental evidence -state anxiety
Will one session of exercise make us feel less anxious?
YES, for at least 2-4 hours post exercise; similar effects to relaxation
Experimental evidence -state anxiety
Quality of evidence is poor
Expectancy bias is inevitable; participants not actually anxious
Decreases anxiety
Intensity
Type
Time
- Moderate and high intensity
- Aerobic exercise dominates research
- 30-45min/session
Neurobiological
Exercise can produce similar changes in the brain neural systems that occur with medication
Limitation to the research
Lots of this work done on animals, generalisability to humans difficult
Psychosocial
-self confidence
Distraction
-Reappraisal of anxiety symptoms
