Cellular Respiration Activity- Clothespins and Muscle Fatigue


Analysis
1.      My strength declines as I progressed through each trial.
2.      My hands and fingers felt tired and cramped during the end of the trials.
3.      Take in more food before I squeeze the clothespin.
4.      The number of times squeezing the clothespin are usually higher for the dominant hand than the non-dominant hand. We regularly use more of our dominant hands in daily activities, the muscles inside already get used to do so much every day. We have a better control of our dominant hands. However, our non-dominant hands are not trained to do so much normally and therefore easier to get fatigue.
5.      In order to get the energy that we need every day, our bodies oxidise the carbohydrates and the energy carrier ATP releases energy and becomes ADP and Pi. There is not enough energy to supply the hand for this series of continuous events immediately (squeezing the clothespin) and therefore gets fatigue. However, after 10 minutes, our muscles recover as the energy comes back.
