it ethical
have to make sure participant is safe to take part
IC - how can we gain informed consent?
verbal or written
written for more dangerous tasks
IC - method of gaining informed consent
write out a questionnaire
sign document
ask them
3 environmental conditions
temperature ⁰c
barometric pressure mmHg
humidity %
BMI formula
BMI = weight/(height²)
drawbacks of BMI
doesnt account for body composition e.g muscle mass vs fat
skinfold measurement instrument
skinfold caliper
skinfold formulas/whats different about them
7 different equations - differ in which measurements they require
Skinfold drawbacks
human error through diff technique/expertise
loose skin from weight loss
blood pressure measurement unit
mmHg - milimeter of mercury
blood pressure normal measurements
120/80
blood pressure top number
systolic pressure
blood pressure bottom number
diastolic pressure
blood pressure range values systolic pressure
100 - 140
blood pressure range value diastolic pressure
60 - 90
blood pressure - factors leading to high bp
high stress
just exercised
naturally high
illness
dehydrated
oxygen saturation - what does it measure
Amount of oxygen saturated with haemoglobin in the blood
oxygen saturation unit of measurement
%
oxygen saturation normal values
95% +
oxygen saturation - factors leading to low
high altitude = lower barometric pressure = lower oxygen saturation
Lung function instrument
spirometer
lung function normal values
80% +
factors affecting lung function
asthma
COPD
covid 19
why we use Heart rate ECG
more accurate/reliable
gives all electrical activity of the heart for each heartbeat
QRS complex
section of ECG training which represents ventricular depolarisation
It shows the beginning of systole and ventricular contraction
