Exercise, affect, mood and depression Flashcards
What is affect?
A general feeling state that is defined in terms of:
Valence- pleasure-displeasure
Arousal-high arousal-sleep
Posner et al (2005) developed which model, displayed as?
Circumplex model and affect
x-axis unpleasant-pleasant
y axis- activation- deactivation
Emotions are described as
Brief and specific affective states that are responses to events.
Involve adaptive functions:
Survival (e.g. disgust)
social communication
innate; yet can be socially manipulated
Ekman (1973) describe 6 primary emotions which are?
Anger Fear Disgust Joy Surprise Sadness
Is affect apparent across species
yes
What is mood described as?
Enduring feeling state accompanied with anticipation of pleasure or pain
Complex: influenced by temperment (intro/extroversion, traits (pessimism/neurotocism) and emotions
biases behaviours and cognitions
profile of mood states (POMS)
Morgan (1980) completed POMS on runners finding
Runners scored low on tension, depression, anger, fatigue and confusion indices. however, scored very high on Vigour.
Thayer et al., (1994) measured how individuals manage mood finding that the most common methods were?
- Exercise
- music
- speak to friend
- tend to chores
- sleep/rest
- reframing
General consensus of mood benefits of exercise is that?
Regular involvement in physical activity appears to reduce depression and anxiety and improves mood (US surgeon general (2000)
10-15 mins of moderate intensity walking can induce positive mood changes (Department of health (2004)
Carron et al (2003) identified that understanding of exercise-affect relations is limited by
- Inconsistency in concepts and methods
- Dose-response issues
- individual response differences
- expectancy and cohort effects
- ecological validity
Yeung (1996) completed a meta-analysis identifying that?
- Exercise enhanced mood/affect for 85% studies
- effective for clinical and non-clinical
- effect weaker in strictest studies
- effects greater for self-selected exercise
- age,sex,fitness had limited impact on effects
- negative effects for females in late stages of pregnancy, hot, conditions, intense exercise
Thayer (1988) anaylsed the dose response for exercise on mood affect finding?
20-60 mins bouts of moderate exercise (DoH,2004)
60-80% of v02 max (Yeung 1986)
yet 10-15 mins walk can enhance vigour and reuce tensions up to 7 hours
If exercise makes us feel better, why arent we all exercising?
Affect becomes increasingly negative and variable at higher intensities* Hardy and Rejeski (1989)
affect during and post exercise may vary
maintenance and rebound models (different pathways for afferent changes)
Rhodes and Kates (2015) impact of affect during/post exercise found
affect during, but not post, exercise predicted future engagement in PA
Exercise needs to be below ventilation threshold to promote future activity
Mechanisms of the effect remain unclear (intentions/slf-efficacy)
Kwan et al (2016) anticipation effect: Positive PAA vs Negative NAA
PAA group anticipated more +ve affect and less fatigue during exercise; yet did not differ in experienced affect and future exercise behaviour
