Dumbbell Exercise is Good for Smart
dumbbell exercises are carried out under the regulation of the central nervous system of the brain. Long-term scientific and systematic exercise of dumbbells can increase the excitement of the central nervous system, deepen the inhibition, and make the excitement and inhibition more concentrated, thereby improving the balance and flexibility of neural processes, and improving the conversion ability of excitement and inhibition of the cerebral cortex, and Enhance the body's regulatory function, activity intensity, reaction speed and accuracy, etc. For example, reading and studying for a long time will make people feel dizzy, hard to concentrate, and slow to think about problems. At this time, we only need to exercise the body with dumbbells, lift a few dumbbells or do a few dumbbell exercises, and then When I go to read and study, I feel very clear-headed. This is because it takes a long time to read and study, and the related nerves will become fatigued and cause a series of reactions. When participating in dumbbell exercises, the motor nerves start to work, and the nerves in charge of reading and learning are rested. Therefore, dumbbell fitness exercise has played a role in regulating nerves and eliminating fatigue. At the same time, in the dumbbell fitness exercise process, because the conversion ability of muscle contraction and relaxation during exercise is improved, the heartbeat is accelerated, blood circulation is promoted, and the amount of blood flowing through the brain per unit time increases, so that brain cells can get better More oxygen and nutrients, in this way, speed up the elimination of nerve fatigue, improve the brain's tolerance to fatigue, and then improve the brain's ability to study and work for a long time. At the same time, dumbbell fitness exercise can release the chemical substances enkephalin and endorphins in the brain to participate in the metabolism, and play a role in improving understanding, thinking and memory, so that people can have agile thinking and strengthen memory. Rich imagination makes the brain smarter.
