When a person stumbles or slips, the nervous system takes just a few milliseconds to send a signal to the muscles and restore balance. If the reaction is delayed, the likelihood of falling significantly increases. For elderly people, such falls often result in fractures, prolonged recovery, and even loss of independence. That is why experts recommend that people over 60 regularly train their reaction speed. > "Reaction speed is the time between when a person notices danger and the beginning of the body's response. For example, when one needs to react quickly to a curb, a slippery surface, or an approaching car. Research shows that this indicator begins to gradually decline after the age of 20, and after 60, the decrease becomes particularly noticeable," said Dana Santas, a certified strength and conditioning specialist, to CNN. According to her, a slowed reaction affects not only safety but also confidence in movements. People begin to avoid walking on uneven terrain, engage in physical activity less frequently, and gradually limit their mobility, which accelerates age-related changes in the body. ## Why Reaction Speed Is Important for the Brain Professional athletes constantly train their reaction because it directly affects their performance. However, in everyday life, this skill receives much less attention, even though it can be developed just like strength or endurance. > "How quickly the brain processes incoming information and sends signals to the muscles reflects the effectiveness of the brain-body interaction," explains Dana Santas. Some studies suggest that a decline in reaction speed may be one of the early signs of age-related brain changes. In one large study, scientists observed nearly 2,800 elderly individuals for over 20 years. The volunteers performed various cognitive exercises—on memory, logical thinking, and information processing speed. The most pronounced effect was shown by reaction speed training. Participants who regularly performed such exercises had about a 25% lower risk of developing dementia compared to those who did not practice them. ## How to Train Reaction Speed at Home The expert recommends performing simple exercises two to three times a week for 5 to 10 minutes. **“Clock” on the wall.** Place sheets with numbers on the wall, like on a clock face. Then play a pre-prepared list of random numbers and touch the corresponding numbers as quickly as possible. **Catching a ball off the wall.** Throw a tennis ball against the wall at different angles and try to catch it after an unpredictable bounce, without letting it touch the floor. **Catching a ball with a partner.** Ask another person to unexpectedly drop a tennis ball from shoulder height. Your task is to catch it before it bounces a second time on the ground. **Lateral movements.** Place two markers about two meters apart. A partner should randomly say "left" or "right," and you need to move in the indicated direction as quickly as possible. According to the specialist, the main principle of such training is the element of surprise. It forces the nervous system to quickly analyze the situation and make a decision, rather than just performing habitual movements. The expert advises recording the results of each training session—such as noting the time taken to complete exercises or the number of mistakes. This will help track progress and maintain motivation. Regular reaction speed training helps make walking more stable, movements more confident, and brain function more efficient. For older adults, this skill can be an important factor in maintaining activity, independence, and quality of life.
