Effect of Exercise on Squeezing a Clothespin

IntroductionDoes exercise make your muscles put ond? In my controlled experiment I investigated this problem. My hypothesis was If I rest first then I can squeeze the clothes peg more(prenominal) times My reason behind this is because during exercise I think you tire yourself out more, so resting forward squeezing could increase number of squeezes. Methods and Materials The materials I used in this experiment were 8 people (subjects) and 8 clothespins of the same type.First I recognized my dependent variable, how many another(prenominal) times you can squeeze clothespin, and my independent, exercise. I took a group of 8 classmates, excluding myself and instead including my younger brother. I decided to allow the control group also serve as the experimental group. The steps I took were to let the control group rest before starting, and then they squeezed the clothespin for one chip and counted how many times they could squeeze it. After that they rested for another minute, then exercised by jogging in place for one minute and after they immediately squeezed the clothespin.Results SubjectExperimental GroupControl GroupMegan 205 226Dane 277 307Nick B 209 235My younger brother 152 136Nick C 194 214Vinny 195 234Dan Average 192 280More subjects squeezed the pin more times resting first. The average of all the data shows this also. flavor at the graph its easier to see the takingss and compare them than the delay. The table does not show a visual comparison but shows the data and numerical information. The table takes longer to read and is harder to understand. The bar graph is easy to point out trends and patterns. The bars, exercising and resting give an easy understanding and show relationships in the data. They compare the disparate amounts of how many times the clothespin was squeezed with each subject.Discussion and ConclusionsExercise does make your muscles fatigued according to my data results. It also supports my hypothesis. If you rest first you c an squeeze the clothespin more times. From the data I collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing. Majority of the subjects used in my experiment concluded with this result too. Muscle fatigue occurs when the muscles soak up an increase in activity so certain bolt out products of muscle cell activity build up in the cells. This is could be true with the results I have concluded.Suggestions for Improvement and Further ResearchTo improve my experiment I could have changed the amount of time you rest squeeze the pin, how long you rest before exercising, how long you exercise, and what type of exercise is done. Changing some of these things could change my results, and result in some further research to be done. To improve my experiments accuracy I could have used more people and have everyone be the same age. A big error made was using my younger brother becau se being much younger he had results lower than many other subjects. Making some of these improvements could make my experiment more reliable. For further research I could research how age affects the hypothesis, or see how things like sexual activity or weight effects the results. Further investigation could help answer these questions.
