Let's Get Wet: A Comparative Analysis of Competitive Freestyle Stroke Methods

Overview

Objectives/Goals The purpose of this experiment is to find the answer to a personal question: What is the fastest way to swim freestyle stroke? I want to compare two different strokes to see if there is any advantage of one stroke style over the other. Methods/Materials For five weeks twice a week I would alternate the two strokes starting with the stroke that I had not started with the previous day. I produced a method of swimming a warm-up of 1000 yard and the swimming a set of four 50-yard sprints. All times were timed by my swimming coach. Results The results show that there was not a significant difference between the two strokes, because I took the standard deviation and the standard deviation of the mean (SDM.) The plus or minus of the SDM turned out to be greater than the difference between the average times for the two strokes. However, the results show that whichever stroke was sprinted first was the faster was the faster sprint throughout the four 50's. Conclusions/Discussion In the 50-yard swim, it does not make a significant difference in time to swim the old way or the new way. What does make a difference is if the stroke is swam first or second. Each of my trials proved that whatever stroke type the day started out with is the fastest stroke of that trial. Therefore, with the data I have collected it appears that neither stroke is obviously faster.
