Exercise & Mental Health
The National Institute of Mental Health recognizes exercise as a valid treatment for anxiety and depression. Levels of neurotransmitters such as serotonin, dopamine, and norepinephrine are higher in those who exercise. These, in turn, may elevate mood, reduce depression, and improve mental focus. Exercise or physical activity assists the psycho-physiological adaptation of emotional stress. Weight training, in particular, has shown to raise body image and global self-esteem. Exercise has been shown to improve mental function and is speculated to enhance creativity and problem solving ability. Exercise can be seen as one of the components essential for physical and mental health in today's society.
Not all peer pressure is bad thing. Giving in to group pressure can be beneficial, particularly when you purposely join a group or exercise with a training partner with similar goals as yours. Positive peer pressure can be used to introduce and reinforce positive behaviors until they become a normal part of your life.
Salvy SJ et al (2007) questioned 10 boys and 10 girls between ages 12 and 14 for one week about their activities and whether they were alone or with others. The presence of peers turned out to be the only significant predictor of the children’s activity intensity. Overweight children reported greater physical activity when in the presence of peers as compared to lean children. Unfortunately, overweight children also reported more time spent alone.

Adherence verses Compliance
Compliance (old medical model) indicates client obeying prescription given by professional as an authority.
Adherence (newer model) indicates client following plan arrived at by both the professional and client as a team.
There should be a compromise between what may be recommended for a client and what they are willing to do. Expecting a client to do exactly what you prescribe risks alienating them to the point of having less of a positive influence on their future behaviors.
Barriers to change
Improving Program Adherence
Dropout from a fitness program is more likely if 3 factors are characteristic of that program are not met:
- high intense exercise is related to higher drop out rates
- length of lay off after injury may be indefinite
- Time of day
- Other obligation and goals outside of exercise must be considered
- Long workouts will have less adherence
- Some may do better with 2 or 3 days a week
- Others may prefer the routine of exercising every day
- Consistency versus flexibility
- Allow for some flexibility by planning an alternative backup time workout due to unforeseen circumstances
- Relying too heavily on backup workout times or implementing cheat days or extended layoffs, whether planned or unplanned, can be problematic for many beginners who have not yet established a regular routine.
- however, they can be helpful for those that may feel certain behavioral goals would otherwise be too restrictive.
- More moderate or progressive changes in diet and exercise may encourage more permanent behavioral changes.
- Time of day
Simplistic Behavior Change Model
A) Antecedents: what cues precede behavior
C) Consequences: what are the consequences
AKA: behaviour confirmation effect
- Individual's expectations influence the their behavior
- Behavior influences the consequence that the individual expected
Body Dismorphic Disorder
Body Dismorphic Disorder (BDD) is a compulsive obsessive ailment characterized by a preoccupation with an imagined physical defect in appearance or a vastly exaggerated concern about a minimal defect. The preoccupation causes significant impairment in the individual's life. Body Dysmorphic Disorder affects 1 in 50 people.
It was once thought that you were born with a set number of brain cells and they just decreased as you got older. Researchers at Salk Institute for Biological Studies discovered walking three hours per week for three months increased many new neurons to grow, causing a measurable increase to the size of the participant's brains. The new neurons tended to grow around areas with well established existing connection and replaced ones that were nonfunctioning. The structure of the brain that grew the most was the hippocampus, the area most involved with memory and cognition.

Exercise and Dementia
Vergese (2003) found no association between physical activity and the risk of dementia. Voluntary exercise can increase levels of brain-derived neurotrophic factor (BDNF) and other growth factors, stimulate neurogenesis, increase resistance to brain insult, and improve learning and mental performance (Cotman 2002). Cognitive and physical activities overlap, so it is not surprising that previous studies have disagreed on the role of physical activities. Although physical activities are important in promoting overall health, its protective effect against dementia remains uncertain.

Hedonic psychology is the study of what makes experiences and life pleasant or unpleasant. It is concerned with feelings of pleasure and pain, of interest and boredom, of joy and sorrow, and of satisfaction and dissatisfaction.
