Nondominant Wear Technix Strength

Over the course of human evolution, the human had gradually changed in its morphology that have allowed for an extensive manipulation of tools and our ability to modulate the strength of our grip allows for adjustment of that strength for the movement of different types of loads (3,2). What we wanted to determine was what kind of relationship may exist, if any, between the muscles on a person’s arm and the muscles in someone’s hand so that if the muscles in the arm are fatigued, would that have any kind of effect on a person’s grip. In addition, we also wanted to determine if grip strength was at all different between someone’s dominant and nondominant hands. So we predicted that there would be a difference in the maximum grip strength and …show more content…
For the dominant hand, we measured an average of 23.5 kg for maximum clench strength before fatigue, an average of 22.75 kg after fatigue, an average of 49 seconds for clench duration before fatigue, and an average of 29.75 seconds after fatigue. For the nondominant hand, we measured an average of 21.25 kg for maximum clench strength before fatigue, an average of 19.75 after fatigue, an average of 35.25 seconds for clench duration before fatigue, and an average of 29 seconds after fatigue. The statistics on collected data indicated that when it came to the maximum grip strength, there was no significant difference before or after the arm muscles had been fatigued, or between the dominant and nondominant hands. In addition, the results also indicated there wasn’t a significant difference in the length of time the grip was maintained from before or after fatigue or between the dominant and nondominant hand. These results suggest that, overall, fatigue to muscles in the arms didn’t have a significant effect on grip strength, indicating that they likely play a minimal role, if any, in producing and maintaining the
