Sport health: how exercise can make our brain healthier

December 10, 2019 / BIOON / -- in recent years, there have been many reports about the negative effects of sports on the brain of athletes But a new study from Northwestern University shows that the brains of athletes in various sports, including football, football and hockey, are healthier than those of non athletes without injury Nina Kraus, senior author, said: "sports bring about better physical adaptability, that is, taking part in sports can regulate the brain, so as to better understand a person's sensory environment." Based on a study of nearly 1000 participants, the authors found that athletes have a higher ability to reduce background electrical noise in the brain, so that they can better deal with external sound (image source: www Pixabay Com) the study will be published in the journal sports health on December 9 "Taking exercise seriously seems to calm the nervous system down," Klaus said Further, if the nervous system is healthier, it may be better able to deal with injuries or other health problems " These findings may inspire people who are struggling with auditory processing to engage in physical intervention In particular, taking part in sports can help children in low-income areas to cope with the over noise in their brains, Klaus said Kraus and her collaborators passed speech syllables through earplugs to participants and used scalp electrodes to record brain activity In addition, the researchers analyzed the ratio of the background noise to the speech response by looking at the size of the voice response relative to the background noise The research shows that athletes have more sensitivity to sound than non athletes Klaus said that like athletes, musicians and multilingual people, their ability to hear voices has also been enhanced But musicians and multilinguals use their brains to turn up the sound in their brains rather than the background noise Source of information: play sports for a health brain original source: Jennifer krizman, Tory Lindley, Silvia bonacina, Danielle colegrove, Travis white schwoch, Nina Kraus Play sports for a quiet brain: evidence from Division I collegiate athletics Sports health: a multidisciplinary approach, 2019; 194173811989227 doi: 10.1177/194173811989275
