The researchers selected more than 5,000 adults between the ages of 20 and 59 and followed them for 15 years. Data analysis found that slower responders had a 25% higher premature death rate than those with average response times. The researchers conclusions remain valid after controlling for other risk factors such as age, gender, race, socioeconomic background, and lifestyle.
Researchers believe that the speed of the reaction can first reveal the operating conditions of the central nervous system and other physiological systems of the body; second, the reaction speed can reflect a person s mental agility and measure the intelligence status, and intelligence is the overall health of the person An important indicator of the index; once again, the speed of reaction reflects the coordination ability of various parts of the body.
In response to this research, geriatric researchers said that a quick response also means that they do not suffer from diseases that affect brain function, such as cognitive impairment, and also prove that there are no problems with agility, accuracy, and balance, and fewer falls Such as accidental injuries, this is of great significance to the extension of life.
Grabbing a ruler with your hand is one of the easiest ways to measure the speed of a response. Experts said, ask others to help press the steel ruler on a smooth wall, and the subject s hand is placed about 20 cm from the end of the ruler. The person holding the ruler suddenly let go, and the subject pressed the falling ruler against the wall at the fastest speed, and then measured the distance the ruler fell. The shorter the distance, the stronger the person s ability to respond.
Neurological experts recommend another test method. The research found that the speed of the finger can also indicate the reaction force. The test subject should move the finger as fast as possible within 10 seconds, and then count the number of times. The more the finger , the faster the reaction. This is because the response speed of a person has a great relationship with the myelin content in the brain. The more the myelin content, the faster the nerve conduction speed, and the faster the finger speed.
Anthony Kelly, a reaction training coach who can grasp a moving object at a speed of 330 kilometers per hour with bare hands, suggests that there can be some conscious training in life to improve the reaction speed.
Practice standing on one leg or squatting, keeping the body in a stable posture, and training the coordination and balance of the whole body. This is the basis for improving responsiveness, but older people should use it with caution.
Muscles can control the speed and strength of the human body s movements. By alternating fast and slow movements, repeated exercises can be used to cultivate the movement memory of the muscles, such as alternating fast and slow running, and exercising dumbbells several times faster and slower.
Rope skipping is more intense than cripple. It can enhance heart and brain function, exercise flexibility and coordination of the brain. At the moment when the rope is leaping, the limbs must be dominated by the brain to ensure that the number of times the arm is roped is consistent with the number of take-offs, which strengthens the brain s responsiveness. However, it should be noted that jumping has a greater impact on the knee and ankle joints. Wear elastic shoes to protect the joints.
Relatively speaking, soothing and safe aerobic exercises such as jogging and walking are very suitable for the elderly to maintain and improve their responsiveness. American studies have found that aerobic exercise can coordinate the limbs, activate the cerebellum, and increase the speed of cognitive and information processing. Just walking 3 times a week for 50 minutes each time can make the response more agile.
Experienced athletes will only pay attention to important relevant clues during the game and ignore irrelevant factors. This is called selective attention. Experts believe that it can help people respond the fastest in a limited time. Selective attention can be trained by playing table tennis, volleyball and other ball sports.
American scholars have found that Mozart dance can improve cognitive ability and response speed of the elderly. The researchers arranged that 65-75-year-olds tested under different music backgrounds, and the results showed that the elderly responded faster and had a lower error rate when they listened to Mozart s trot.
Experts believe that drinking alcohol in life is very important, and every drunk will cause damage to brain cells. Usually eat more reduced foods such as spinach, tomatoes, carrots, soybeans, garlic, etc., which can help brain cells resist attack . You should also eat foods rich in omega-3 fatty acids, such as deep-sea fish such as salmon and tuna, and walnuts., Almonds and other nuts, can protect the brain.
