What is the average resting breathing rate?
12-15 breaths
Definition of breathing rate
The number of inspirations or expirations (breaths) per minute
What is the symbol to represent tidal volume?
TV
What is the average resting tidal volume?
500ml
Definition of tidal volume
The volume of air inspired or expired per breath
What is the piece of equipment used to measure lung volumes?
Spirometer
What is the symbol used for minute ventilation?
VE
What is the equation to calculate minute ventilation?
VE = TV x f
Definition of minute ventilation?
The volume of air inspired or expired per minute
What is the average resting minute ventilation?
6-7.5 l/min
Why may an aerobic athletes VE be lower?
They have more efficient gaseous exchange and transport, they can meet the demands for oxygen more efficiently at rest
What is the comparison of values of f, TV and VE for an untrained and trained athlete at rest
