Lecture 20 - Physical Activity Flashcards
what is physical activity statement 1 NZ
sit less, move more
break up periods of prolonged sitting
what does WHO recommend about sedentary time
limit the amount of time spent being sedentary
replace with more physical activity of any intensity
a study found that above 8 hours a day of sedentary time, every additional hour of sedentary time was associated with a
4% higher all cause mortality
a study found that above 6 hours a day of sedentary time, every additional hour of sedentary time was associated with a
4% higher CVD mortality
a study found associations between sedentary time and cancer mortality were
not statistically significant
if you do heaps of physical activity what has been found
then it might protect you from being sedentary
there is a relationship between sedentary and
physical activity in terms of your risk
increase physical activity and reduce sedentary time to reduce risk
what is meant about the pattern of accumulation is important
found to be better to break up sedentary time than being a prolonged sitter
what was found about glucose response of those who walked on treadmill for 1 minute 40 secs every half an hour compared to those who walked for 30 minutes then sat for the rest of the day
reduced glucose response after meals of those who got up and moved
what is the second physical activity guideline in New Zealand
do at least 2.5 hours of moderate or 1.25 hours of vigorous physical activity spread throughout the week
what is physical activity statement 3
for extra benefit aim for 5 hours of moderate or 2.5 hours vigorous activity spread throughout the week
what does the WHO recommend about physical activity
at least 150 to 300 minutes moderate intensity aerobic physical activity
or
at least 75 to 150 minutes vigorous intensity aerobic physical activity
what does the WHO recommend for additional health benefits
more than 300 minutes moderate intensity aerobic physical activity
or
more than 150 minutes vigorous intensity aerobic physical activity
WHO recommends what minutes of moderate PA per week where the benefits are the greatest
150 - 300 minutes
what is activity statement 4 NZ
do muscle strengthening activities on at least 2 days each week
what does WHO recommend about strength training
on at least 2 days a week muscle strengthening activities at moderate or greater intensity that involve all major muscle groups
strength based exercise is also associated with
- decreased risk of falls
- increased prevention of bone mineral density
- increased preservation of muscle mass
what type of strength training had the lowest hazard ratio for CVD mortality
both gym based and own body weight training
what is activity statement 5 NZ
doing some physical activity is better than doing none
the WHO determines what good practice statements in relation to physical activity
- doing some physical activity is better than doing none
- if adults are not meeting these recommendations, doing some physical activity will benefit their health
- adults should start by doing small amounts of physical activity, and gradually increase the frequency, intensity and duration over time
MoH statement on managing the risk of exercise
if you have a health condition, you may wish to consult your doctor of physical activity specialist before starting physical activity
what is a PARQ and what does it mean
screening tool to assess the risk of contradictions from physical activity
what does it mean if someone answers yes to any of the PARQ questions
refer to an exercise specialist or medical professional
the benefits of physical activity outweight
the risks
- physical activity is safe, even for people living with symptoms from multiple medical conditions
the risk of adverse events is
very low but thats not how people feel
exercise prescription is not as easy as
just telling someone to move
what is meant by everyone has their own standing point
help people identify their own starting point, begin there and build up gradually
when should we stop and seek medical review
if you notice
- dramatic increase in breathlessness
- new or worsening chest pain and or increasing GTN requirement
- a sudden onset of rapid palpitations or irregular heartbeat
- a reduction in exercise capacity or change in vision
what is GTN
glyceryl trinitrate
