Health Flashcards
Health Belief Model
predicts the likelihood an individual may partake in a health behaviour
perceived susceptibility and perceived seriousness –> perceived threat –> likelihood of action
perceived benefits and perceived barriers –> outcome expectations –> likelihood of action
perceived threat
the extent of danger associated with the task
perceived seriousness
how bad will it be for them, the extent of risk
perceived susceptibility
the likelihood of it occurring
perceived benefits
how good will this be
Theory of Planned Behaviour
intention required to carry out the behaviour
attitude toward behaviour, subjective norms and perceived behavioural control –> behavioural intention –> actual behaviour
- can go from perceived behavioural control straight to actual behaviour
Implementation Intention
developing a specific plan that can be translated into something actionable
Obesity
measurements of BMI is not consistent with overall health and fitness, muscles weigh more than fat
this means health behaviour is important as it defines physical health more accurately
Stress Response
amygdala sends alert to hypothalamus
- endocrine system creates adrenaline and cortisol
- sends to cardiovascular system, musculoskeletal system, respiratory system, digestive system and immune system
Stress and Hormones
During stress the endocrine system restricts the release of hormones to other systems. Instead, it attributes hormones to the stress area, possibly creating an imbalance in hormones during chronic periods
Stress and reaction of other Systems
can negatively effect the musculoskeletal, cardiovascular, respiratory, digestive and immune systems
Stress Causing Illness
Stress –> health behaviours –> illness
Stress –> physiological activation –> illness
Acute Stress
short-term, clear beginning and end
Chronic Stress
long-term, prolonged, no clear end
Selye’s General Adaptation Syndrome (Stages)
Stage One: Alarm - fight or flight, sympathetic nervous system, stress hormones
Stage Two: Resistance - body tries to counteract physiological changes from stage one, reinvigorate homeostasis, parasympathetic nervous system
Stage Three: Exhaustion - energy depletion, body no longer able to fight stress, unable to cope, damage to organ or immune system
