Causes of Shaking Feet and Hands After Exercising
Have you ever felt trembling in your feet and hands or tremors after exercising? If so, the thing you need to pay attention to is what happens when you exercise. In skeletal muscle, cells never contract as clusters of muscle cells which collectively connect to motor nerves originating from the spinal cord.
Reasons for body shaking after exercise
When exercising, these motor units are not all excited when the muscles are electrically pumped and made to contract. In fact, these motor units race in the least synchronized manner by the electrical impulses descending from the motor nerves from the spinal cord.
Meanwhile, some motor units contract and shorten in the abdominal muscles during exercise. However, the other nerve will relax and lengthen. A large number of nerves overlap between the motor units giving the impression that the muscle is contracting smoothly as a whole.
Strenuous exercise causes some motor units to go out of motion due to fatigue. This is the process that is ultimately responsible for the shaking or shaking you feel in your feet and hands. Most of the possible fatigue in the spinal cord at the level of the motor nerve cells and their nerve connections.
Although some nerves are exhausted, there may also be connections between these motor nerves and their muscle cells. Both of these areas require the synthesis and release of certain chemicals to carry electrical impulses across one of the other nerve cells or muscle cells.
Researchers generally believe that chemicals in the body cannot be produced and released fast enough to keep up with the level of activity during exercise. Because of this, these chemicals become depleted and cause the body (especially the feet and hands) to tremble. Maybe this also happened due to fatigue.
As more and more motor units become temporarily non-functional, muscle contraction becomes increasingly dependent on fewer motor units. Disconnection of the exhausted motor unit causes the remaining individual contractions and relaxation to become more synchronized and less well organized.
Prevent Dehydration from Shaking after Exercise
Dehydration negatively impacts exercise performance in many ways. It doesn’t take much to see the effect. Even losing as little as 1-2 percent of your body mass through sweat can reduce exercise capacity.
When it hits the muscles, dehydration slows down blood flow, and it is the blood that is responsible for transporting essential nutrients (such as electrolytes) to the working muscles. When the muscles don’t receive enough blood flow or nutrients, they can’t work as efficiently as possible, making them more prone to shaking or tremors.
To prevent dehydration-induced muscle shaking, aim to drink 11-13 glasses of water per day. Also make sure to keep drinking during exercise, especially if you exercise when it’s hot.
