The reason why running requires the most exhales is that of all the exercises, running requires the most muscle contractions. The contraction of muscles requires ATP as energy in order to function. Since oxygen is a reactant in the formula to produce ATP, more oxygen must be taken in in order to increase the production of ATP. This oxygen is taken in by breathing, explaining why exercises with more muscle contractions, require more exhales per minute. Since squats require a few contractions, the exhales per minute is slightly lower, with sitting at rest having the least exhales per minute as no muscle contractions are required.

By squeezing my fingers against them, I was able to feel thousands of tiny little bubbles. I really wonder how different a live lung of a chainsmoker would look like. Would it appear smaller? Would it be of a different colour]]> 2017-08-23 01:47:22 UTC https://padlet.com/181036/x1i05qi545rw/wish/182229934 181036 https://padlet.com/181036/x1i05qi545rw/wish/182231387 This graph allowed me to understand that the air is warmer when breathing through your nose, than it is when breathing through the mouth. I came to this conclusion as the temperature change of the first run, where air was inhaled through the nose and exhaled through the mouth, was more significant than that of the second run, where air was inhaled and exhaled through the mouth.]]> 2017-08-23 01:58:07 UTC https://padlet.com/181036/x1i05qi545rw/wish/182231387 181036 https://padlet.com/181036/x1i05qi545rw/wish/182953931 https://docs.google.com/document/d/13Fzhqt68hgaRRGJXYq1Lt9zvKLdERvJUr4nEhwGKB7M/edit ]]> 2017-08-27 00:21:43 UTC https://padlet.com/181036/x1i05qi545rw/wish/182953931 181036 https://padlet.com/181036/x1i05qi545rw/wish/182953971 In this exercise, a plastic straw is connected to my neck with blue-tac, around the area of the artery, where the pulse can be felt. The anatomy of that can be described are the plastic straw, blue tac that attaches the straw to my neck, and the artery located in that spot on my neck. In terms of physiology, what is happening is that when the artery expands and contracts, its vibrations cause the straw to make small movements. For exercise physiology, I believe that by exercising, the straw would move more frequently because as the heart-rate would increase, and cause the pulse felt on the neck to increase, thus causing the straw to move more rapidly. ]]> 2017-08-27 00:22:43 UTC https://padlet.com/181036/x1i05qi545rw/wish/182953971 181036 https://padlet.com/181036/x1i05qi545rw/wish/183373825 2017-08-29 13:10:05 UTC https://padlet.com/181036/x1i05qi545rw/wish/183373825
