Do singers have a larger lung capacity than non-singers?
The hypothesis that choir singer will have greater lung capacity than non-singers is proven to be true. Through training, the students were able to strengthen their chest muscles to inhale and exhale more air and therefore increase their lung capacity.
The capacity of our lungs indicates the condition of our health. All of the cells in our body require oxygen therefore it is very important to keep our lungs healthy. Activities like smoking, which reduce our lung capacity must be avoided
The experiment can be repeated by athletes instead of choir singers.
Try to repeat the experiment using a spirometer instead of balloons to measure lung capacity.
