measured using three pieces of filter paper. Two pieces of first aid tape were attached to each piece of filter paper. The filter paper with the tape was then weighted and its mass was recorded as the dry mass. At the start of each of the three activity periods one filter paper was attached to the volunteer’s forehead and the first aid tape was there to hold it in place. At the end of the each of the three activity periods the wet weight of the filter paper was recorded. (Marion, et. al., 2015). The independent variable was manipulated by the time of the exercise were done and the capacity the volunteer could reach in that amount. The dependent variable was measured after the exercises were done.

There was a slight increase of sweat during the activity period. There was .01 mass of sweat and the sweat rate was of 1.6x10^-14 grams of sweat per hour. During both rest periods there was 0.1 mass of sweat and the sweat rate was of 1.6x10^-4 grams of sweat per hour. The volunteer during the rest pre-exercise period had the average respiratory rate of 28 breaths per minute. I got this number because at minute 4 the respiratory rate was 32 breaths per minute. At 8 minutes the respiratory rate was of 24 breaths per minute and at 12 minutes the respiratory rate was 32 breaths. I added all of these numbers then divided by 3 in order to find the average. The average

respiratory rate during the activity period increased and it was 52.8 breaths per minute. During the rest post-exercise period the average respiratory rate decreased and was the same as it was during the rest pre-exercise period. The average respiratory volume before exercising was 3.1 liters per breath. The average respiratory volume decreased during the activity period to 0.3 liters per breath. After exercising the average respiratory volume continued to decrease to 0.14 liters

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
