3. Let's get physical! Flashcards
The World Health Organisation (2010) guidelines for physical activity recommend that adults aged between
18-64 years old should engage in at least 150 minutes of moderate-intensity aerobic physical activity each week or 75 minutes of high-intensity physical activity
almost ____ of the adult Australian population are not meeting these guidelines
45 percent
increased cardiovascular exercise and strength training has been found to significantly reduce
depressive symptoms (Paluska & Schwenk, 2000
There is also evidence that physical exercise can help with symptoms of
anxiety, such that the effects appear to match those of meditation and relaxation.
It also appears that acute anxiety responds better to physical activity
than chronic anxiety
A meta-analysis of meta-analyses!) of 92 papers examining the effect of physical activity on depression and anxiety in non-clinical populations, Rebar et al. (2015) found a moderate effect of physical activity in reducing
depression and a small effect of physical activity in reducing anxiety.
a recent longitudinal study by Hiles, Lamers, Milaneschi, and Penninx (2017) explored the potential bi-directional relationship between depression, anxiety, and physical activity and found that
there did appear to be a mutually reinforcing relationship
The underlying mechanisms by which physical activity effects psychological well-being are
not well understood in the literature
Wilson and Dishman (2015) conducted a meta-analysis on the role of personality traits in physical activity and found that
traits that lower extraversion and conscientiousness, as well as higher neuroticism, were associated with lower physical activity
social-psychological explanations have argued that physical activity may improve psychological well-being through increasing
self-efficacy and/or resilience and strengthening social networks
meta-analyses showing that greater levels of physical activity can reduce the risk of dementia by
28% and Alzheimer’s disease by 45%
Within some countries, particularly in lower socioeconomic-status data-collection sites, research has shown a preference for
heavier bodies (Swami et al., 2010
Eating disorders now appear to be rising in other world regions, such as
Asia and the Middle East, and among Hispanic and African Americans in North America
internet trend referred to as “thinspiration” has given way to a newer trend of
“Fitsperation” where images of bodies and information are shared to motivate and inspire body image goals
