kin 2276 midterm Flashcards
PA vs exercise
PA = any movement from muscles that require energy expenditure
exercise = sub type of PA; planned, structured and repeated that has a specific goal/intention
what are the 6 aspects included in exercise psych and explain them
- social psych = understanding how people function in groups
- exercise sci
- health psych = promoting health deteriorating behaviour like eating, dieting, sleeping behaviours
-behavioural medicine - rehab psych
- sport and performance psych = focuses on optimizing performance whereas ex-psych focuses on individual experience
what does traditional focus of exercise mean ?
applying psychological principles to promote and maintain leisure time PA behaviour and/or exercise
what does it mean to understand the psychological consequences of exercise?
reducing negative and promoting positive psychological state
what does contemporary directions mean?
‘dark side’ of exercise cognition and behaviours and understanding the factors that may be associated with exercise avoidance or ‘non-adherence’
define epidemiology
the study of epidemics; dealing with the incidence, distribution and control of a disease in a population
what % of the country’s residents are insufficiently active
35-55
what is most sensitive to age related changes (age group goes up PA goes down)
high intensity PA
which age group in Canada receives the highest levels of PA
12-17
define adoption, adherence and noncompliance
adoption = who adopts PA behaviour and exercise for what reasons
adherence = how much the person does the exercise, reps, sets etc
noncompliance = implies there is a right way to engage in PA and exercise
not only guideline differences but also cut off differences meaning the standards that are used to classify PA, inactivity, sedentary behaviour are sometimes used interchangeably in some countries and used distinctly in others. True or false?
true
what % of Canadian children and youth meet guidelines fo MVPA?
36%
for 5-17 year olds, what are the guidelines to a healthy 24 hours? hint: think of the #4 shaped graph
60 min MVPA, several hours of light PA, 9-11 hrs of sleep for 5-13 yr olds and 8-10 hrs of sleep for 14-17 yr olds, no more than 2 hours of sedentary behaviour of screen time
define gender vs sex
gender = socially constructed roles
sex = biological attributes of humans and animals
give some examples as to why racial minorities might have lower levels of PA in North America
possible systemic racism built into institutions , socio-economic factors, different countries have different cultural norms and priorities that can play into the importance of PA
what do we see when it comes to income level and PA?
lower levels of PA based on income level
what do we know about education level and PA?
% that meets guidelines increases with higher education levels
what are some subject methods of measuring PA
questionnaires, recalls, diaries, logs
what are some objective methods of measuring PA
pedometers, accelerometers, direct observation, physiological measurements
_____ increases while _____ decreases in feasibility vs precision
accuracy; feasibility
what is the most feasible tool and one limit to it?
self-reporting but it is not as precise
physical inactivity is not the same thing as engaging in high levels of sedentary behaviour T or D
true
define sedentary behaviour
any behaviour w energy expenditure <= 1.5 METs
by what % of risk of death in Canadian adults is reduced with increased levels of PA
20-35
as MVPA per week increases mortality decreases. T or F and explain
false, morbidity decreases
at what point in MPA per week does the biggest decline in risk happen
at 150 min of MPA per week
tell me about sedentary behaviour and sitting behaviour
- linear reduction in risk associated with increasing amount of PA
- around 8-15 hours, the difference in risk id quiet low compared to the initial reduction in sitting time/sedentary behaviour
define theories vs models
models = abstract representations of global concepts that describe a phenomenon (can be graphically represented)
theories = specific depictions that explain why phenomenon or behaviour occurred (can be graphically represented)
what are the importance of theories
- gives better understanding and predictions for PA behaviour
- can be used to create hypothesis –> conduct research –> observe results
what is the stimulus-response theory
- how people learn new behaviours
- most effective theory bc it has a shorter time frame where response is being given to stimulus which is more effective
what is stimulus response theory based on. explain
classical conditioning (pavlov and his dogs)
- a non-voluntary behaviour that can be elicited through repeated pairing of behaviour with an antecedent cue
- can help us understand instrumental conditioning
what are some limitations of the stimulus-response theory
- does not consider the role of cognitions about an outcome (beliefs, intentions, motives and emotions)
- limited in its ability to predict and explain exercise behaviour
- uptake of exercise/PA despite punishment and extinction
what are the 4 types of events that can impact a future behaviour
- positive reinforcement
- negative reinforcement
- punishment
- extinction
what is instrumental conditioning
- voluntary behaviour that can be learned by pairing the behaviour with consequent reinforcement
- helps understand patterns of reinforcement
what is positive reinforcement (driving force)
- enjoyable or pleasant outcomes that make a person feel good and strengthen a particular behaviour
- when new behaviours add positive consequences
what are the reinforcers within positive reinforcement
- intrinsic reinforcers = rewards that come from within oneself
- extrinsic reinforcers = rewards that come from other people (or that you give yourself)
what is negative reinforcement (driving force)
- unpleasant or aversive stimuli that, when withdrawn after a behaviour, will increase the frequency of that behaviour in the future
- when new behaviours remove negative consequences
- eg reduction in joint stiffness
define punishment (restraining force)
- unpleasant or uncomfortable stimulus encountered after a behaviour DECREASING THE PROBABILITY of that behaviour happening in the future
- eg muscle soreness (negative consequence added on)
- PA should NEVER be used as a punishment, otherwise individuals will see it as highly aversive
what is extinction (restraining force)
- withholding a positive stimulus after a behaviour in order to decrease the likelihood of that behaviour happening again in the future
- removal of a positive consequence after engaging in PA making it less likely to engage in that PA next time
- eg decreasing opportunities to socialize
what is behavioural economics
- offering financial rewards for PA
- evidence of positive reinforcement and extinction
what are social cognitive theories
theories that explain future exercise behaviour as determined by personal, behavioural and enviornmental processes
what is the self-efficacy theory
- human motivation and action is not merely a response to past behaviour (eg SRT)
- describes how individuals form perceptions about their capability to engage in specific behaviours
- focuses on the extent to which individuals feel they will be successful, given a particular set of abilities and their unique situations
- a situation-specific form of self-confidence/competence (we as humans are driven to do things that we are good at
- extremely task specific
