Sprinter Sacre reclaimed his two-mile crown with a convincin

BOSTON - NFL veterans who started playing tackle football before the age of 12 are more likely to have cognitive difficulties after their careers, according to a study published on Wednesday in the journal Neurology. Anthony Zettel Jersey .Researchers tested 42 former players on their short-term memory, mental flexibility and problem solving and found those who picked up the sport before they were 12 years old functioned about 20 per cent worse. Both groups scored below average on many of the tests, according to Robert Stern of the Boston University School of Medicine.There is a known period of critical brain development that occurs around puberty. And if the brain is injured during that time, it may have both short-term and long-term consequences, Stern told The Associated Press. This study supports that idea that we need to protect the brains of our children while theyre going through this dramatic development period.The release of the study during Super Bowl week was a reminder for fans — especially those who are also parents — that the sport has bigger problems than deflated footballs.For the study, NFL players were divided into two groups: those who played as young children, and those who did not. Those in the former group performed worse on the cognitive tests, such as being asked to recall words from a list they had learned 15 minutes earlier.The brain is the most critical organ in our body. Its responsible for every aspect of thinking, feeling, moving, behaving; its responsible for who we are, Stern said. So the question is: Do we want to expose our children to anything that may have significant negative consequences for how that brain is going to work later in life?The difficulty faced by the former players, who reported an average of nearly 400 concussions each during their lifetimes, is separate from the problem of chronic traumatic encephalopathy, which can only be diagnosed after death.Stern said the research does not lead to any simple solutions.Among the limitations of the study, which he conducted with researcher Julie Stamm, were that it only looked at former NFL players; the conclusions cannot be generalized to a broader population. Youth sports also have many health benefits that need to be considered by policymakers, sports organizations and parents, Stern said.It also looked back at people who played a long time ago; conditions could have gotten better as concussion education improved — or worse, because athletes are getting bigger and faster. There is a need for so many follow-up studies, Stern said.The issue for me is one of science being balanced with logic, he said. It does not make sense to me, as someone who studies the brain and as someone who has four kids, to foster repetitive hits to the kids brains at a young age. Does that really make logical sense? Do we want to do that to our children at that age whose brains are rapidly developing?Stern, whose research into CTE has helped lead to a greater understanding of the dangers of concussions, said he isnt ready to write off the sport. Although he said he can no longer watch youth football, he is still a New England Patriots fan who is planning to attend the Super Bowl on Sunday.Im not sure how to deal with this incongruity between what I know and what I like to watch, he said. Im not saying we need to get rid of football. For me to be going to the Super Bowl this year, with the Patriots playing, Im giddy with excitement. And that, along with watching the game on Sundays, makes for a huge amount of self-questioning.

Hendersons charge had bounced back to form on this day 12 months ago at Cheltenham when landing the Shloer Chase, sparking emotional celebrations in the winners enclosure.He went on an unbeaten run following that victory, winning three more times including his second Champion Chase victory at Cheltenham in March. His final racecourse appearance was to be at Sandown in April, where he demolished Un De Sceaux by 15 lengths. Watch NOW TV Watch Sky Sports for just £6.99. No contract. Sprinter Sacre had returned to work ahead of a planned reappearance in Sandowns Tingle Creek Chase next month, but after exercising on Tuesday was found to have some heat in his near-fore leg, prompting connections to make the decision to retire him.At a specially-convened press conference at the racecourse, an emotional Henderson said: Hes been a great part of our lives. Nico de Boinville celebrates winning the Betway Queen Mother Champion Chase What happened last year was something that will never be repeated in my lifetime. In terms of emotion it took us all to the brink.He will be here today and he looks as well as hes ever done. Hes in staggeringly good form. The sad thing is that he is doing everything right. The delighted rider gives Sprinter a hug If you saw him now, you wouldnt know which leg it was, but theres a little bit of heat in his near-fore that has shown up on the scan. If he was seven, youd say give him a year off and hed be back. But hes not seven any more and this is the right thing to do.For a long time I protected See You Then and said he was our best horse but during Sprinter Sacres best two years, he was unbeatable. Literally unbeatable. Sprinter Sacre (left) beats Cue Card to win the Racing Post Arkle Challenge Trophy Steeple Chase Im sad for him because hes come here today thinking hes going to have a race and hes all excited and ready to show his public what he can do, but at least people will have the opportunity to see him again today.Sprinter Sacres most recent partner and the jockey under whom he took last seasons Champion Chase was Nico De Boinville, and Henderson went on: Nico has been with Sprinter from the start. He rode him every day at home when Barry Geraghty wwas his jockey and they have always been great friends. T.J. Lang Jersey. Sprinter Sacre soars over a fence earlier in the contest I had to ring him this morning to let him know just before he went into surgery for the arm he broke here yesterday. It wasnt the easiest conversation to tell him his mate wont be there for him to ride when he comes back.Sprinter Sacre won 18 of his 24 starts and amassed £1,136,000 in prize-money.In between his two Champion Chase victories, however, he was plagued with problems before returning to something approaching his best last season.Joining the Henderson stable from France, he made a winning debut in an Ascot bumper in February 2010 and went novice hurdling the following campaign.After winning two of his first three starts, he was then third in the Supreme Novices Hurdle in March 2011.It was a chaser he really made his mark, though.He created a big impression in his novice season which saw him defeat Cue Card in the Arkle Trophy in 2012.Sprinter Sacre went on to win his first 10 races over fences, including the Champion Chase at the 2013 Cheltenham Festival.But his successful streak came to an abrupt halt when he was pulled up in the Desert Orchid Chase at Kempton that December, after which it transpired he had an irregular heartbeat.He made a full recovery and returned to action in January 2015 when he was second to Dodging Bullets in the Clarence House Chase at Ascot.But when he was pulled up in that seasons Champion Chase it seemed his best days were behind him.However, he came back in tremendous form last season and after wins in the Shloer Chase and the Desert Orchid Chase, Sprinter Sacre reclaimed his two-mile crown with a convincing defeat of Un De Sceaux at the Festival in March.He wound up the campaign with a similarly authoritative victory in the Celebration Chase at Sandown in April in what turned out to be his swansong.Explaining Sprinter Sacres career-ending injury, Henderson said: It all crept up yesterday. He worked on Tuesday and everything was grand.We were just a bit worried on Wednesday night as he was warm in one leg. I was going to work him yesterday but we couldnt work him.We cant ask him to come back, not at his age.Hes in the same stable he has always spent his days in here (at Cheltenham) and you wouldnt know which leg I was talking about. In fact, if I was thinking about working this afternoon him I would.It (the injury) wouldnt hold up in the short term and when you cant go for the long term, you have to sadly bite the bullet.Barry Geraghty rode Sprinter Sacre 17 times, winning on 13 occasions, and said his old ally was just unbelievable.The jockey said; Hes something special and he is to be celebrated. Ive never sat on a horse over fences like him - he was electric.The first day he won here (in the 2012 Arkle), just to see him sail away on the way to the last, Ive never seen that before.He was just unbelievable.
