For this project we research and did an experiment about muscle fatigue. The variable we used was the height of a
person, because each member of the team has a different height. The height of a person affects highly the quality
of their performance. The taller you are, the more weight you carry which slows you down and makes you get tired
quicker. Our hypothesis, which was proven correct, was: If you are taller you will have less resistance and get tired
quicker. Each member of the team jumped for 30 seconds, for ten continuous trials. We recorded the data in a
table and from the smallest to tallest the points were less. We think we exercise appropriately and we avoided
conflicting variables affecting our result, we did the experiment very precisely and with the time it required, each
member had a role assigned each time the experiment was performed. By looking at the results we can tell that the
lactic acid started to build during the trail number 5 because that was when we, the subjects, stared to loss a lot of
energy and oxygen and we started to breathe heavily. The changes we think should be changed in the protocol are
having small interval breaks during the 10 trials and have some water to drink because the students performing it in
the future are going to need it. No matter what your height is if you like exercising then don´t let anything stop you!
