MODULE FOUR Flashcards
leisure time pA
an activity undertaken in the individuals time that increases total daily expenditure
sport definition
activity spectrum that is institutionalised, organised practice, reined over by specific rules
exercise definition
activity that is planned, structured and repetitive, that help to improve and maintain physical fitness.
what is physical inactivity compared to sedentary behaviours
physical inactivity is the non-achievement of physical guidelines whereas sedentary behaviours is any waking behaviours characterised by an energy expenditure less than 1.5 METs in a setting, reclining, lying posture
the benefits of PA do not necessarily outweigh ….
the harmful effects of sedentary behaviour
eg. lying in bed for 23 hours then out for 1 hour is worse than sedentary behaviours, therefore our guidelines need to show this
self reporting of PA issues
- those that are not physically active under report this physically active levels
- those that are so physically active will over report their physically active levels
so overall this isn’t very good
150 minutes active guidelines criticism
it is good to get to this number but the more the better
why are we less physically active
busier lives and we have less understanding of importance of PA
and then stuff like invention of transport and chairs
what is the main reason NZ say the most barrier to doing PA is
other commitment that take priority
inactivity physiology effects
increase risk of poor health
what is health definition
a state of complete physical, mental and social wellbeing and not merely the absence of disease or infirmity
life expectancy
we are living long, but unhealthy but we need to change this
life expectancy is going up, but life expectancy and health is rising slower
NCDs
things that are not transferrable to others
eg. diabetes
3 things to have on you PA
over load
progression
specificity
westernised societies seek for their population to attain
longevity and to minimise any disabling conditions
the number of people over 65+ in NZ has
doubled since 1980 and will likely to double again by 2036
life expectancy is increasing but healthy life expectancy
isn’t increasing as fast
rural area and ageing population challenge
rural areas are ageing faster than urban areas. this is because young people are always leaving rural areas for uni and other opportunities. therefore in these rural areas we need to make sure we have the right accessibility for the elders.
challenges with life expectancies and workforce
as people get older they struggle to find a life purpose so they tend to work for longer, however this creates a issue as those younger then struggle to find jobs our of uni. therefore we need to find something for the elders to do
negative attitudes towards ageing people starts at and when people have them
per-school children
when people have the negative attitude as they age they will walk slower and have worse cognitive abilities
what are the four strategies for morbidity compression
- primordial prevention: prevention of risk factors from developing
- primary prevention: reduction of risk factor prevalence
- secondary prevention: prevention of disease progression
- tertiary prevention: reduction of morbid states that have already occurred
normal ageing
is associated with changes that increase vulnerability to accidents r disease, BUT ageing itself is not a disease
are age-related disease progressive
yes, but can be 50% can be prevented, early/mid life
sarcopenia
progressive and generalised loss of skeletal muscle and strength, which can lead to disability, poor quality of life and death.
it is one of the 4 main reasons for loss of muscle mass
ageing associated changes in muscle tissue
fast type 2 fibres become slow type 1 fibres, so the imbalance becomes bigger. this is why they may struggle to stand up
lipids between muscle fibres
at what age do you want to be at your peak muscle and bone mass
30
osteoporosis
decrease in he density of bone, decreasing strength and resulting in fragile bones. the bones become compressible like a sponge, which results in frequent fractures
osteopenia is the diagnosis before you reach osteoporosis as your bones are a bit more dense
why is unhealthy increasing life expectancy an issue
large burden on our health care system
what is exercise prescription
is the type, intensity, duration and frequency of PA. it is a purposeful program that has been set, that is for PA and heath.
