This means that your grip strength fatigues with time. In my day to day life, if I am taking notes by hand, I need to give my hand a rest due to muscle fatigue.
10. The change in amplitude in electrical activity increased by 8.5% from the 0-20 second time interval to the 60-80 second time interval. There is a larger difference in amplitude in electrical activity during the 60-80 second time interval due to muscle fatigue as a result of holding your grip for a longer period of time. 11. The mean grip strength during the 80-100 second time interval is slightly higher than the 0-20 second time interval. This supports the practice of “coaching from the sidelines” because grip strength increased during the longer time interval when the muscle should be more fatigued. This demonstrates the principle of “mind over muscle”. 12. Our neuromuscular system attempts to overcome fatigue during heavy work or exercise by exerting less force. However, the brain is able to overcome this fatigue by taking voluntary control over the muscles. This is seen in the 80-100 second time interval when mean grip strength actually increased with the help of verbal encouragement. Muscle
