Superiority In Grip Strength: Athletes or Non-athletes?
Overview
Objectives The objective of my project was to clearly see the correlation between the athletes and non-athletes grips strength versus the independent variable, which was the length and hand span in inches. My goal was to see if the their correlations would have a positive, negative, or no linear correlation. Methods I used a hand dynamometer to test the grip strength in pounds, I connect to a labquest 2, both products were borrowed from my mentor. I used excel spread sheets to display my data and to help make my graphs. Results My results showed that each graph had a positive linear correlation, since I used Pearson's Correlation to see if this would be my outcome. Athletes did have a superior correlation in both categories I was testing, but the difference wasn't as large as I expected it to be. Conclusions This project expands in providing athletes or people looking for an improved physical health, the range that their grip strength should be in. This can help people realize that a low grip strength could be potential implications for diseases, such as heart disease.
Summary statement
I observed the correlations of an athlete's grip strength were higher than those of non-athletes.
Help received
My mentor provided the hand dynamometer and LabQuest 2, but I decided to use Pearson's Correlation to carry out the data analysis in my experiment.
