Detailed explanation-1: -Several medical conditions can make a person feel weak, shaky, and tired. They include dehydration, irregular heart beat, Parkinson’s disease, and chronic fatigue syndrome. Treatment will depend on the condition a person has.
Detailed explanation-2: -The more strenuous the activity, the more motor units are needed to complete the task. As the exercise becomes more fatiguing towards the end of the workout, more muscle fibers have to step in to take the place of the other depleted motor units. This is where the shaking and trembling comes into play.
Detailed explanation-3: -Tremor can be the result of muscle weakness and problems with posture, or a side effect of some medications (such as drugs for asthma). It could also be caused by other neurological conditions, such as Parkinson’s.
Detailed explanation-4: -Your nerves and muscles are powered by blood sugar. When they don’t get enough, they tell your hands to shake. Low blood sugar can be caused by diabetes, certain medications, too much alcohol, or not enough food. A doctor can help you narrow down what’s happening and why.
