Compared to before and after exercise, there is a difference in CO2 levels.

# data[].attributes.body
Yes there is a difference between co2 quality before and after exercise

There is a difference between exhaled air before and after exercising

# data[].attributes.body
There is a difference between quantity of CO2 exhaled after exercise compared to when you are at rest.

# data[].attributes.body
There is a difference in CO2 quantity in exhaled air at rest vs. after exercise because of the amount of carbon dioxide exhaled.

# data[].attributes.body
There is a difference in CO2 quantity in exhaled air at rest vs after exercise, due to factors like lung capacity.

# data[].attributes.body
The quantity of CO2 in exhaled air at rest is less that the quantity of CO2 after exercise due to the use of O2.

# data[].attributes.body
Yes there is a difference between the quantity of CO2 exhaled after exercise compared to before.

# data[].attributes.body
Everyone has different lung capacity and size so that would make everyone’s numbers different

# data[].attributes.body
Everyone’s lungs have the ability to hold different amounts of oxygen and they will therefore release different amounts of co2.

Each body is different, which means the lung capacities are different.
