THE STUDY OF HAND STRENGTH UNDER VARIOUS CONDITIONS
Addie E
2013-2014

ABSTRACT
The purpose of this study was to determine which conditions affect a human’s hand strength and how it is affected. Different parts of the upper body collaborate to provide hand grip, including the muscles and tendons in the hand itself. A hand strength probe was used in every experiment to measure the force the test subjects could exert. Hands are built to still function under different circumstances, making it very difficult to significantly alter a person’s strength. Fatigue is the most effective way to affect the strength a person can exert with their hands, but only if their hands fatigue over a longer period of time.

EXPERIMENTAL IMPROVEMENTS AND FUTURE EXPERIMENTS
To improve these experiments, it should have been made clearer to the test subjects to use their dominant hand. Sometimes, a test subject would ask which hand they were supposed to be using. They would be informed that they should be using their dominant hand, and then the test subject would have to do the experiment over again if they were using the wrong hand. This was a minor issue and occurred rarely, but the project would have been more time efficient if this improvement had been put into action. Future experiments could involve fatigue or take aspects of this project to more extreme levels.
