How long will you live? This exercise test may have the answer
A new study has shown how a simple exercise could predict natural and cardiovascular causes of death.
Researchers wanted to see whether non-aerobic physical fitness, assessed by a sitting-rising test, could predict premature deaths in middle-aged and older people, and on Wednesday, their results were published in the European Journal of Preventive Cardiology.
They tested the theory on 4,282 adults aged 46-75 years from 1998 to 2023. Most of the participants, 68 percent, were men. 'None of them presented relevant physical or clinical limitations for fitness testing,' researchers said.
All of the participants performed a sitting-rising test to evaluate the main components of non-aerobic physical fitness, which are muscle strength/power, flexibility, balance and body composition.
The test was simple, yet not necessarily easy. Participants had to sit and rise from the floor without other body parts such as hands, elbows or knees touching the floor.
Their instructions were as follows: ''Without worrying about the speed of movement, try to sit and then rise from the floor, using the minimum support that you believe is needed,'' the study's authors wrote.
If participants used any extremities for support, they'd lose points. They also needed to steady themselves as a perceived partial loss of balance would knock down their score.
Researchers found that non-aerobic physical fitness 'was a significant predictor' of natural and cardiovascular mortality in the participants.
After following up with patients about 12 years later, researchers found there were 665 deaths due to natural causes.
Those who scored a perfect 10 points on the sitting-rising test had death rates of 3.7 percent. Death rates tripled to 11.1 percent for people with a score of 8 points and 'dramatically increased' by 42.1 percent for those with a score of 0 to 4 points, according to researchers.
The study was done at a private clinic in Rio de Janeiro, Brazil, and most of the participants 'belonged to upper socioeconomic and education strata of the country.'

The 10-second fitness test you can do at home to predict your lifespan
If you can't stand up without needing help, you're more likely to die in the next 10 years, a study suggests. Researchers in Brazil gave over 4,000 adults a flexibility test to lower themselves on to the floor from a standing position and then get back up. They were asked to do so with as little assistance as possible, such as using their hands, furniture or other people around them for balance. Participants were then scored on a scale of zero to five for both sitting down and standing up, starting with five points and then losing one for each type of support needed. The team found people who needed no help to sit down or stand up were six times less likely to die of heart disease or other cardiac issues within the next decade than those who wobbled or had more trouble. And each one-point decline in score was associated with a one-third greater chance of dying of heart disease or other natural causes like cancer. The test may be a good approximation because muscle strength and flexibility are thought to lower blood pressure and resting heart rate and reduce full-body inflammation, which can lower the risk of heart disease. Researchers said while other studies have used balance and flexibility tests to measure longevity, the new study is the first to measure 'muscle strength/power, flexibility, balance and body composition' all at once. Claudio Gil Araujo, lead study author and research director at an exercise-medicine clinic in Rio de Janeiro, where the data was collected, told the Washington Post: 'What makes this test special is that it looks at all of them at once, which is why we think it can be such a strong predictor.' The researchers looked at 4,282 adults in Brazil ages 46 to 75, two thirds of whom were men. The average age was 59. After 12 years on average, 15.5 percent of participants died of natural causes. Of those, 35 percent died of cardiovascular disease, 28 percent of cancer and 11 percent of respiratory diseases like pneumonia. At the outset of the research, each participant was asked to sit down from a standing position and then get back up after. They started with five points for each test and lost one point for every level of support they needed. This could include using their knees, holding on to a chair or taking someone's hand. Participants also lost half a point every time they lost their balance or seemed unsteady. Researchers then combined each person's sitting and standing scores to get the final result, with a maximum of 10. People who scored zero to four points total had a six-fold increased chance of dying from cardiovascular disease than those who got a perfect 10. Half of those who scored a zero on the test to get up off the floor died during the follow-up period compared to four percent of those who got a perfect score, an 11-fold difference. Additionally, participants who scored between 4.5 and 7.5 were two to three times more likely to die in the next decade from heart disease or other natural causes. Each one-point score decrease was associated with a 31 percent increased risk of cardiovascular death and 31 percent greater chance of death in the next decade from other natural causes. The researchers also found after adjusting for factors like age, sex and body mass index (BMI), people with a history of coronary artery disease were three times more likely to die from natural causes compared to healthy participants. There were several limitations to the study, however, including all of the participants being from a private clinic in Brazil, leading to a less diverse sample size. There was also no data on smoking status, a leading cause of death from heart disease and lung cancer. To try the test for yourself, Dr Araujo suggests finding a partner to score you and steady you if you start to fall. People with joint issues should avoid trying it due to the risk of unnecessary injury. Clear space around you but ensure there is a wall, chair or other support object nearby. Remove your shoes and socks and consider putting a pad down on bare floors. Stand with your feet slightly apart and cross one foot in front of the other. Lower yourself until you are sitting on the ground and then stand back up, trying not to use support. While there was a correlation between the scores and mortality, it is important to visit a doctor to get a full picture of health, as well as risk factors for different diseases.

Isle of Man's veteran's hand crank challenge to 'inspire others'
An army veteran who completed the equivalent distance of the Isle of Man's Parish Walk on a hand crank machine after losing the use of his legs said he hoped his efforts would "inspire others".Mike Ryan said he decided to complete the 85-mile (137km) challenge at the National Sports Centre (NSC) as the event's route would be "impossible" in a wheelchair due to the said he had decided to take on the venture, which he completed in just over six hours, to "surprise" himself and demonstrate to others "I am more than what you see".Mr Ryan said: "It is easy for people to look at people with a disability and think they are 50% of the next person... give me an option to be judged on a level playing field and I won't come last." The former member of the Royal Engineers said he decided to use the hand crank machine, which is designed to improve upper body fitness, because it was the only piece of exercise equipment he could use that registered a distance. Mr Ryan, who served in the British Army between 1994 and 2001 and did tours of Germany, Bosnia and Northern Ireland, said he broke his legs in more than 140 places over a three year was referred to the NSC by the island's mental health services due to developing post-traumatic stress disorder (PTSD) after leaving military service. Attending the gym sessions "helps me get out of the house more and combat stress", he said he had "jokingly" asked to sign up for the Parish Walk Challenge at the NSC, which sees entrants complete the distance of the walk on a variety of gym equipment, but had then taken it on in receiving a medal for completing the task, he said although it was different from the annual walk itself it was no less of an achievement."I know it is not the same as completing the Parish Walk, but I would say to anyone to go and do 85 miles in a day is challenging, even if it is not the same challenge," he others with PTSD to seek help, he said: "Don't suffer in silence like I did for a few years."Completing the challenge in six hours and 15 minutes, Mr Ryan raised about £650 for local charity Bridge the Gap, which aims to help young people with long-term health conditions.

Screen children in schools to find lazy eyes early, experts say
Children with a lazy eye are being increasingly missed for treatment, experts say, in areas where early screenings are not available in councils are unable to offer the service due to capacity or budget constraints, according to the Local Government Association (LGA), which is calling for increased British and Irish Orthoptic Society (BIOS) says screening for amblyopia, the medical name for the lazy eye condition, should be provided in all schools in England, as it is in Wales, Scotland and Northern condition, where one eye is weaker than the other, is corrected using patching, but treatment works best before the age of seven. Ellen and Robert Hopkins say they were devastated to find out their son Harry had a lazy eye when they brought him for his first test when he was six-and-a-half years two and five per cent of children like Harry are diagnosed with amblyopia every UK National Screening Committee recommends vision screening for children aged four to five, but about 11% of local authorities do not offer it in has been wearing a patch for the past few months, but his progress has tapered off since he reached his seventh birthday."We'd definitely like to have known about it earlier," mum Ellen says."If we'd known about it when he was three or four, or perhaps at the start of school, then he would have had longer to work on it."Harry's dad Robert said it was a "fluke" they brought him for an eye test, after he thought he was looking past him when they were having a chat after dinner in their home in Derbyshire."When I was a child I was tested in school, I can't believe kids aren't tested because with conditions like this you have a limited amount of time to make an improvement or not," he Murray, chair of BIOS, says it is a hard condition for parents to spot early, and that it is a "postcode lottery" for families on whether they are offered screening or not."We are finding more of those cases of older children who are coming in and they weren't screened, and now it's too late for them to have that amblyopia treated," he said. Around 75,000 children now live in areas that do not offer school screening, according to a BIOS areas like Derbyshire, Lincolnshire and North Yorkshire, parents are instead given advice in their child's early development checks, or are signposted towards free NHS tests at their local invite parents to complete a digital health screening questionnaire when children start school to highlight any Smedley, who carries out vision screening in Sheffield schools, says it is a good way to make sure most children are groups of four, she takes the reception children at Marlcliffe Primary School out to the IT room to be 800 children have been referred on for further checks so far this year in the county."Parents often say to us, 'There is no way we would have known that there was a problem if screening wasn't there,'" she says."And if they weren't picked up, they wouldn't be able to access certain jobs later on in life, or even drive a car when they're older, so it's significantly important." Marlcliffe Primary School's head teacher Clare Hayes agrees."It can be difficult for families with busy lives to make appointments at the opticians," she says. "And as parents and teachers, we may not always detect difficulties that children are having with their vision because the children have adapted and got used to that being their sight."Cllr David Fothergill, from the LGA, says he would like to see an increase in the public health grant which funds school-based screening, so that councils can commission and deliver the full range of services needed to improve child says he believes the government's recent spending review overlooked public health the government said a £200m boost in funding, announced earlier this year, would help support local authorities to tackle the root causes of ill health, and build healthier communities say that parents should still bring their children for regular NHS-funded eye tests from the age of three or four every one to two years - even if they do live in areas that screen in schools. Daniel Hardiman-McCartney, from the College of Optometrists, says school vision screening is a good safety net for children's vision, but it is not the same as an eye test at a local opticians - and both are research by the college found many parents are confused about their children's eye health, and only take them for a test if they notice a parents Ellen and Robert are encouraging everyone to make sure they get their child's eyes tested early, even if they are not able to read progress in Harry's right eye is being closely monitored to see if patching is still making a difference, and they say it is thankfully not stopping him from doing his favourite thing – journalism by Kady Wardell and Katherine Gaynor
