Exercise Stats
• 25-40% adults in US aren’t active in free time
• 20-25% don’t meet recommended activity levels
• 42% us kids active for recommended time
- only 8% youth
Focus of Exercise Psych
- Exercise and mental health
* Issues is physical activity behaviour change and exercise adherence
Exercise & Mental Health
- Exercise/physical activity is good for mental health
* Associated with lowered anxiety and depression, increase in self-esteem
Exercise & Mental Health: Anxiety
- Typically reduced after moderate-vigorous exercise session
- Anxiety reduction was greatest when sessions lasted at least 30 minutes
- No consensus on what kind or how much exercise
Exercise & Mental Health: Depression
• Can help reduce signs/symptoms of depression in ways similar to antidepressants
Exercise & Mental Health: Distress and Well-Being
- Psychological distress is risk factor for psychiatric disorders, coronary disease, and poorer quality of life
- Evidence not clear on effects of exercise training
Exercise & Mental Health: Sleep
- 50-70 Americans experience sleep disorders
- Evidence shows higher levels of usual physical activity appear to be protective against incident and chronic insomnia in older adults
- Exercise led to improvements in in sleep for those who previously experienced problems
- No long term effects are known
Feelings of Fatigue or Low Energy
- About 20% of adults report persisting feelings of fatigue
* Controlled trials showed moderate reduction in symptoms of fatigue from exercise
Exercise & Mental Health: Self-Esteem
- Provides feeling of value/worth
- Strongest evidence for positive effects of exercise on mental health is for self-esteem
- Changes more likely in kids
Exercise & Mental Health: Cognitive Function
- Can improve cognitive functioning in older adults and kids
- Fitness related to tasks that are novel, complex, require attention and fast processing speed
- Cardio Respiratory Fitness and chronic aerobic exercise training facilitate executive control functions of cognition in older adults
Physical Activity Behaviour Change
• Adults have trouble maintaining active lifestyle
Canadian Physical Activity Guidelines
- Adults between 18-64 should have at least 150 mins of moderate-to-vigorous exercise/week
- Just over 15% of Canadian adults meet guidelines
- Only 5% accumulate their 150 mins/week
- 47% do less than 30 mins/week
Sedentary Hours
• Most adults spend about 9.5 hours/day sedentary
Theories of Exercise Behaviour: Social-Cognitive Theory (Bandura)
- Personal factors, environmental influences and behaviour all affect each other
- People who adopt challenging goals and believe they can attain them are the most motivated to exercise
Theories of Exercise Behaviour: Self-determination theory
- Belief that intrinsic motives for exercise develop and interact with physical and social environments to influence physical activity
- Assumes that people strive for autonomy, competence and relatedness
Theories of Exercise Behaviour: Behaviour Modification Theory
- Systematic application of principles of learning to the modification of behaviour
- Minimizes the role of thoughts, motives, and perceptions
- E.g., written agreements, behavioural contracts, lotteries, etc
Theories of Exercise Behaviour: Transtheoretical Model
• Behaviour change is seen as dynamic process that occurs through a series of stages
- Precontemplation – not thinking about exercise
- Contemplation – considering exercise
- Preparation – plan is made
- Action – have started exercise
- Maintenance – exercise behaviour continues
Research Issues in Exercise Behaviour
- Use of cross-sectional correlational designs – lack of longitudinal studies
- Poorly validated measures of moderators and mediators
- Self-reported measures of physical activity
- Limited use of stat procedures
Endorphin Hypothesis
- Research is mixed on presence of endorphins after exercise
* Other transmitter systems may be responsible for enhanced mood effects
Neurotrophin Hypothesis
- Brain derived neurotrophic factor (BDNF) – chemical that plays large role in development of adult brain plasticity
- Significantly lower in depressive depressive groups
- Concentrations elevated in response to acute aerobic exercise; no lasting effects
Monoamine Hypothesis
- Neurotransmitters believed to be involved in pathogenies of several mental health disorders and include dopamine, norepinephrine, and serotonin
- MHPG – metabolite of epinephrine
Distraction Hypothesis
• Distraction from stressful stimuli
Performance Consulting
Helps with issues like - performance anxiety - motivational problems - negative self-talk - concentration issues • Athletes may bring up personal issues
Depression
- Quite common
- Physical activity associated with prevention of depression
- High levels of PA = high self esteem
- Athletes experience depression following losses/poor performance
