I believe that in daily life, we can always hear "simple mind, developed limbs".
Why is this said? Is the mind and limbs doomed to repulsion?
In fact, this is a living habit derived from the ancients.
It should be known that the life of the ancients was limited, and reading and livelihood were often unbalanced, which led to manual laborers having to participate in labor production for a long time in order to make a living, and there was not much time and financial resources to study, so the level of education was generally low.
In order to be able to obtain a meritorious name, the reader has to study hard indoors, and rarely has time to participate in physical exercise, so he seems weak and can't help but wind.
But in fact, with the increasing level of productivity, this statement obviously does not hold true.
The brain is smart, and it has nothing to do with whether the limbs are developed or not
Back in March 2017, an article was published in the Journal of the American Geriatrics Scoiety in which researchers recruited 100 people over the age of 55 with mild cognitive impairments.
At the same time, these elderly people are randomly assigned into 4 groups, a group of elderly people for resistance training + cognitive training (a recognized effective method for cognitive function improvement), a group of elderly people for false sports training + cognitive training, a group of elderly people for resistance training + false cognitive training, a group of elderly people for false sports training + false resistance training.
For fake exercise training, the researchers took stretching training and sitting gymnastics training with low activity intensity and little significant increase in heart rate and strength;
For pseudo-cognitive training, the researchers took observations of general documentary footage and then asked several related questions.
The real resistance training is that the strength of the resistance amount is between 80-92% of 1RM, and the load of 1RM adjusted force is retested every 3 weeks.
True cognitive training takes a computer-based training of various brain functions, such as memory, executive ability, attention and information processing ability.
These elderly people are trained according to their group, through up to 6 months, 2-3 times a week training, so as to measure their cognitive level.
Exercise can not only improve physical conditions, but also improve the function of the brain
Regular exercise can not only benefit physical and mental health, but also help regulate the hormones in the brain that can bring great benefits to brain health.
What are the specific benefits of regular exercise for the brain?
1. Help improve mood
Exercise can change the levels of hormones such as dopamine and serotonin, which can help improve mood and bring happiness to people, and are very beneficial for helping to alleviate the symptoms of severe depression.
2. Help improve sleep
Exercising for more than an hour a week can help reduce anxiety and self-stress, which in turn can help improve the quality of sleep and make people get better sleep, and high-quality sleep is good for brain health.
It is best not to exercise in the two or three hours before going to bed, so as not to affect sleep.
3. Prevent degenerative diseases and improve cognitive ability
Daily exercise can improve blood flow to the brain, thereby reducing the risk of degenerative diseases such as Alzheimer's disease and helping the brain function and grow normally.
Long-term adherence to exercise can also change the function and structure of the brain, thereby improving the health of the human body and cognitive function.
4. Enhance memory and improve concentration
Exercise can stimulate the vestibular system of the brain, which will cause changes in areas of the brain, such as the parietal cortex, hippocampus, etc., which in turn can improve memory.
Insisting on exercise can also improve the efficiency of the human body, the ability to react, and is conducive to improving people's attention and concentration, which can enable people who insist on exercise to better face the challenges of daily life.
5. Increase the size of the hippocampus
Aging causes changes in the size of the hippocampus in the brain, which in turn can lead to memory loss and dementia. Adults who exercise regularly, especially those who undergo aerobic exercise, will have a larger volume of hippocampus and the middle temporal lobe.
6. Enhance creativity
Insisting on aerobic exercise can make people maintain a positive and optimistic mood, and people will have more concentration and more energy, which is conducive to enhancing their own creative thinking and making people more creative.
Therefore, exercise not only makes our bodies stronger, but also makes our brains smarter.
Developed limbs≠ simple mind, I don't believe you look at the students of Tsinghua University, look at their graduation conditions and morning running system, maybe you will have a different harvest.
