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.

Kangana Ranaut shown black flags in Himachal's Lahaul and Spiti, BJP files complaint with CEO
Shimla, May 20: Actor Kangana Ranaut, BJP candidate from the Mandi parliamentary constituency, was shown black flags by local people and Congress workers at Kaza in Lahaul and Spiti on Monday.
The Himachal Pradesh BJP filed a complaint with the state chief electoral officer (CEO) demanding transfer of election officials and an investigation into the incident as both the BJP and the Congress were given permission to hold rallies adjacent to each other.
The Congress workers raised anti-Kangana slogans - "Kangana, go back, Kangana Vangana nahi chalegi". They were apparently enraged over her remarks on Tibetan spiritual leader Dalai Lama in April last year.
Ranaut had tweeted a meme featuring the Dalai Lama that said, "The Dalai Lama receives a warm welcome at the White house". The photoshopped picture in the tweet showed the Dalai Lama sticking his tongue out with US President Joe Biden with a comment - Both of them have the same illness, definitely they could be friends.
Following this, a group of Buddhists staged a dharna outside her office in Mumbai.
Later she apologised saying she didn't mean to hurt anyone, and it was a harmless joke about Biden being friends with the Dalai Lama.
Leader of the Opposition in the Himachal Pradesh Assembly Jai Ram Thakur, who had accompanied Ranaut to Kaza to campaign for the BJP, on Monday alleged that the Congress workers tried to disturb the meeting of the BJP and pelted stones on their carcade while they were returning.
Talking to reporters, he said, "It is unfortunate that for the first time, permission was given to hold a parallel rally at the venue to the Congress where prior permission was already granted to the BJP to hold the rally.
Efforts were made to disturb our rally and the Congress workers raised shameful slogans, stopped our carcade and pelted stones, injuring one person."
Thakur added that they go for campaigning all over the state but such things have happened for the first time, which shows "frustration" of the Congress and they would take up the issue with the Election Commission.
Later, in a complaint filed with the Himachal Pradesh CEO, BJP state office secretary Parmod Kumar Thakur said the Congress workers allegedly tried to illegally restrain the political procession and even pelted stones and demanded an investigation into the incident.
"The district administration granted permission for organising a political meeting to the Congress adjacent to the place already scheduled to hold a political meeting of the BJP at Kaza under undue influence of the state government in utter violation of the Model Code of Conduct (MCC)", he said.
In the complaint, the BJP demanded the immediate transfer of election officials from Lahaul and Spiti and said giving permission to both the parties at the same location at the same time was a "big lapse" on the part of the Election Commission "in spite of the fact that permission to the BJP was provided first and the officers involved in this act are biased against the BJP, and free and fair elections are doubtful under the circumstances."
Lahaul and Spiti SP Mayank Chowdhary told PTI that workers of both the BJP and the ruling Congress came face to face but there was no clash and no person was injured. However, one worker sprained his leg, he added.
Bhishan Shashni, Congress election coordinator for Lahaul and Spiti claimed that the Congress workers were peacefully protesting but a large number of people, who were hurt by Ranaut's remarks about the Tibetan spiritual leader, joined the protest.
Earlier, Congress candidate from the Mandi Lok Sabha seat Vikramaditya Singh had asked why Ranaut did not visit Spiti and returned from Reckong Peo alleging that she was afraid she would be shown black flags for her remarks against the Dalai Lama.
