Overview
• What is green exercise?
• Effects and mechanisms of:
    – Exercise
    – Nature
•   Research questions
•   University of Essex studies
•   University of Canberra studies
•   Summary
•   Recommendations
•   Discussion                       3
What is green exercise?
Physical exercise
performed in (relatively)
  natural settings.
Examples of green exercise
   Mountain
    biking

                 Canoeing

     Fitness   Gardening
                 Gardening
      trails


                             5
Exercise:
             Effects
• 15 to 30+ min. bouts of moderate
  intensity aerobic exercise are
  associated with well-demonstrated
  physical and psychological
  health benefits (mood, anxiety,
  stress).
• Some studies show benefits from
  less intense exercise.
                                      6
Exercise:
          Mechanisms

• Thermogenic changes
• Cardiovascular conditioning
• Neurobiological
  (endorphins; norepinephrine)
• Distraction
• Mastery (self-efficacy)
                                 7
Nature:
              Effects
There are positive physical and
psychological health benefits of:
• Viewing nature
 (e.g., through window)
• Being in presence of nature
 (e.g., access to green spaces)
• Active participation and
  involvement with nature
 (e.g., gardening, green exercise)
                                     8
Nature:
          Mechanisms
• Psycho-evolutionary theories
  – Biophilia hypothesis (Wilson)
  – Nature-deficit disorder (Louv)
• Restorative theories
  – Psychophysiological stress
   recovery theory (Ulrich; Hartig)
  – Attention restoration theory
   (Kaplan & Kaplan)                  9
Green exercise:
    Research questions
  What are the effects of
      green exercise?
       How and why
   do any effects occur?
What psychological processes
        are critical?
                           10

Summary
• UC studies found moderate short-
  term improvements in +ve and -ve
  indicators of psychological well-
  being.
• Results congruent with UK green
  exercise research (Barton & Pretty, 2010;
 Pretty et al., 2005, 2007)




                                              32
Summary
• Predictors:
  – ↑ Greenness – weak effect - may
    enhance some outcomes
  – ? Cognitions – weak effect –
    environmental cognitions may enhance
    some outcomes
  – ? Activity Type – weak, occasional effect
  – = Intensity – little to no effect
  – = Duration - no effect
  – = Connectedness to Nature - no effect
                                            33
Recommendations
• Green exercise participants report
  psychological benefits.
• Incorporate pleasant natural
  exercise spaces and trails into
  urban areas.
• Further research (using a variety
  of methods) is needed about
  psychological processes that
  underlie green exercise effects.

  • 27. Mackay (2008): Results • Outcomes –↓ Stress (d = .38) –↓ Anxiety (d = .51) • Predictors –* Activity Type – positive effects for all except the 2 running groups –↑ Greenness – small, positive effect i.e., greener the perceived environment, greater anxiety reductions –= Duration – no effect –= Intensity – no effect 27
  • 28. Holgate (2010): Design • N = 114 from 13 indoor and outdoor exercise groups in the ACT • Dependent variables: – Mood (negative affect, vitality, happiness) • Independent variables – Cognitive strategies (associative, dissociative, environmental) – Exercise characteristics (Greenness, Socialness, Intensity, Competitiveness, Expertise, Frequency) 28
  • 29. Holgate (2010): Results • Outcomes and predictors –↓ Negative affect (d = .62) • No predictors –↑ Vitality (d = .57) • Predicted by ↑ Env. cognition (β = .24) –↑ Global happiness (d = .29) • Predicted by ↑ Intensity (β = .16) 29
  • 30. Rugendyke (2012): Design • N = 105 from 5 ACT outdoor exercise groups • Dependent variables: – Stress (PSS) – Mood (PANAS) • Independent variables: – Connectedness to nature (CNS; Mayer & Frantz, 2004) – Environmental cognition (EC) 30
  • 31. Rugendyke (2012): Results • Outcomes –↓ Stress (d = .65) –↑ Mood • ↓ Negative affect (d = .70) • ↑ Positive affect (d = .67) • Predictors –= Connected to nature – no effect –= Env. cognition – no effect –Controlled for cognitions (dissociative & associative), demographic & exercise characteristics 31
  • 32. Summary • UC studies found moderate short- term improvements in +ve and -ve indicators of psychological well- being. • Results congruent with UK green exercise research (Barton & Pretty, 2010; Pretty et al., 2005, 2007) 32
  • 33. Summary • Predictors: – ↑ Greenness – weak effect - may enhance some outcomes – ? Cognitions – weak effect – environmental cognitions may enhance some outcomes – ? Activity Type – weak, occasional effect – = Intensity – little to no effect – = Duration - no effect – = Connectedness to Nature - no effect 33
  • 34. Recommendations • Green exercise participants report psychological benefits. • Incorporate pleasant natural exercise spaces and trails into urban areas. • Further research (using a variety of methods) is needed about psychological processes that underlie green exercise effects. 34

  1. The effects of green exercise on stress, anxiety and mood: The role of perceived greenness, exercise cognitions, and connection to nature James T. Neill Graham Mackay Brent Holgate Amy Rugendyke Centre for Applied Psychology University of Canberra 27-30 September, 2012, 47 th Annual Australian Psychological Society Conference, 27-30 September, 2012, Perth, Western Australia This presentation is copyright by the authors and available under Creative Commons Attribution (CC-by-A), http://creativecommons.org/licenses/by/3.0/ license.

Osgood Abstract There is growing interest in and recognition of the importance of the natural environment in people’s physical and psychological well-being. We have known for some time that physical exercise is vital for well-being and also that spending time in relatively natural environments has calming, restorative effects (Maller et al., 2008). What happens when physical exercise is combined with natural environments is now being studied as “green exercise”. Early field and lab-based green exercise studies identified short-term improvements in self-esteem and mood. However, much remains unknown about the mechanisms by which green exercise may create positive effects, the range of psychological impacts, and what types of green exercise can be recommended. In a series of related field studies, the pioneering green exercise research by Jules Pretty and colleagues at the University of Essex (e.g., Barton & Pretty, 2010), has been followed up and extended at the University of Canberra (e.g., Mackay & Neill, 2010), with findings indicating moderate that positive effects on stress, anxiety and mood can be partially explained by perceived greenness, cognitions during exercise, and connectedness to nature, whilst duration and intensity of exercise tends not to predict measured outcomes. This presentation will describe three related green exercise field studies conducted at the University of Canberra, each involving over 10 naturally occurring green exercise groups, with sample sizes over 100 participants. Moderated effects on measured outcomes (stress, anxiety, and mood) are evident, with novel measures developed for these studies to investigate perceived and desired environmental greenness, environmental cognitions during exercise, and Mayer and Frantz’s (2004) measure of connectedness to exercise, offering potential insight into recommended mechanisms for enhancing positive psychological change. Through such studies, green exercise appears to be emerging as a promising, evidence-based, low-cost, preventative and rehabilitative psychological and physical health strategy, with greater understanding about green exercise processes and effects likely to be developed through further replication and application of other research methodologies.

  8. Urbanisation: Increasing numbers of people living in urban environments and the development of theory and research about the restorative effects and benefits of nature on mental and physical well-being Psychophysiological stress recovery theory: Affective and aesthetic response to visual stimuli “ It proposes that restoration may occur if a scene elicits feelings of mild to moderate interest, pleasantness, and calm, and that whilst viewing nature, positive affect replaces negative affect resulting in lower physiological arousal (Hartig, 2004). Hartig explains that when an environment is unthreatening, aesthetically pleasing and elicits feelings of interest, restorative functioning occurs allowing a shift toward a more positive psychological state. This theory suggests that individual responses to nature have an important physiological component, impacting psychological changes (Ulrich, 1983).” (Rugendyke, 2012) Attention restoration theory: Recovery from directed attention fatigue “Kaplan and Kaplan's (1989) Attention Restoration Theory suggests that nature provides cognitive restoration by allowing attention-focusing capacities to rest. Central to this theory is directed attention whereby an individual can use voluntary control and sort unimportant from important information, minimise distraction and select appropriate focus (Kaplan, 2001). Becoming over-stimulated in urban settings may result in fatigue of directed attention and restorative environments, such as natural settings may aid in the recovery of directed attention. Thus, nature can provide a restorative experience, involving relaxation and allowing an individual to become revitalised and refreshed (Kaplan, & Kaplan, 1989; Kaplan, 2001). Kaplan suggests that four elements must be present in an environment for restoration to occur. These are: temporary escape from one’s normal environment, a sense of interest that captures attention effortlessly, engagement in surroundings whilst having coherence of being part of a larger whole and an environment that is fitting with individual preference. Consistent with this theory, psychological benefits of green exercise may arguably be affected by one’s awareness/cognitions (directed attention) of the environment and one’s preference for nature (connectedness with nature).” (Rugendyke, 2012)

Exercise groups: Running, Bush walking, Casual walking, Orienteering, Soccer training Perceived Stress Scale (PSS; Cohen, Kamark & Mermelstein, 1983) Positive and Negative Affect Schedule (PANAS; Watson, Clark & Tellegen, 1988) Connectedness to Nature Scale (CNS; Mayer & Frantz, 2004). Participant cognitions during exercise were measured using the 23-item scale adapted by Holgate (2010). This measure asked participants to rate the extent to which Associative, Dissociative, and Environmental Cognitions were engaged in. The measure included 14 items from the Attentional Focus Questionnaire (AFQ; Brewer et al., 1996).
