Study claims stronger people have sharper brains
London, April 21: If you thought hitting the gym only builds your physical strength, think again. A study of nearly half a million people has revealed that stronger people perform better in brain functioning tests.
Muscular strength, measured by handgrip, is an indication of how healthy our brains are, said the study published in the journal Schizophrenia Bulletin.
"Our study confirms that people who are stronger do indeed tend to have better functioning brains," said study co-author Joseph Firth from NICM Health Research Institute, Western Sydney University, Australia.
Using data from the 475,397 participants from all around Britain, the new study showed that on average, stronger people performed better in brain functioning tests that included reaction speed, logical problem solving, and multiple different tests of memory.
The study, which used UK Biobank data, showed the relationships were consistently strong in both people aged under 55 and those aged over 55. Previous studies had only shown this applies in elderly people.
The findings also showed that maximal handgrip was strongly correlated with both visual memory and reaction time in over one thousand people with psychotic disorders such as schizophrenia.
"We can see there is a clear connection between muscular strength and brain health," Firth, who is also an honorary research fellow at the University of Manchester in Britain, said.
"But really, what we need now, are more studies to test if we can actually make our brains healthier by doing things which make our muscles stronger -- such as weight training," he added.
Previous research by the group has already found that aerobic exercise can improve brain health.
"These sorts of novel interventions, such as weight training, could be particularly beneficial for people with mental health conditions," Firth said.
"Our research has shown that the connections between muscular strength and brain functioning also exist in people experiencing schizophrenia, major depression and bipolar disorder -- all of which can interfere with regular brain functioning," he added.
"This raises the strong possibility that weight training exercises could actually improve both the physical and mental functioning of people with these conditions," he said.

AAP leader says police booked him for protest for Wangchuk
New Delhi (PTI): AAP leader Saurabh Bharadwaj on Monday claimed that he was booked by police for taking out a candle march in support of climate activist Sonam Wangchuk.
The Delhi Aam Aadmi Party president said he was booked even though the case against Wangchuk had ended.
"This new case has been registered for a candle march is registered for a candle light March at Jantar Mantar on the day Wangchuk was arrested," he said, terming it a "fake" case.
The Delhi Police was yet to respond to the allegation.
Earlier in the day, the Supreme Court disposed of a plea by Wangchuk's wife against the detention of the activist under the National Security Act (NSA).
A bench of Justices Aravind Kumar and PB Varale noted that the Centre had revoked its order of Wangchuk's detention on March 14, and there was nothing left in the matter.
Wangchuk was detained on September 26 last year, two days after the protests over demands for statehood for Ladakh and its inclusion under the Sixth Schedule of the Constitution rocked Leh.
More than 45 people, including 22 policemen, were injured in the protests.
