NEW YORK -- The best thing young players can do for their basketball careers is not play too much basketball.They should participate in other sports and delay specializing in just basketball until they are at least 14 years old. They should also take at least one day off from organized competition each week and extended time off at least once a year for proper physical and mental recovery.Those were among the guidelines announced Monday by the NBA and USA Basketball to begin Jr. NBA Week. The Jr. NBA is the leagues youth basketball participation program for boys and girls ages 6-14. The research and recommendations come from panels of medical experts, former players, and coaches and administrators throughout basketball.They found that athletes who have the most success played multiple sports at a young age and didnt focus on a specific one until late adolescence.The idea of sampling and participating in other sports does not mean youre getting behind, said Dr. John DiFiori, NBA director of sports medicine and UCLA team physician. They actually provide a strong foundation for success in your sport.LeBron James, perhaps the NBAs best player, played football through his junior year of high school. But those who focus on basketball too soon face some risks that can last well beyond their teen years.Theres a concern that single sport specialization may contribute to injuries and may also contribute to basically loss of interest in the sport from sort of the repetition of incessant participation in one activity, DiFiori said, adding there are cases of young athletes developing overuse injuries specific to a certain sport.NBA commissioner Adam Silver has made player health one of his biggest concerns, working to create a schedule that allows more time for rest and recovery. The league went further earlier this year by looking into the youth levels.Working groups were created in the areas of health and wellness, playing standards, and curriculum and instruction. Their guidelines stressed the importance of time away from the court, with recommendations on amount of practice and game time, and even amount of sleep.I think sometimes parents and coaches can forget that there are only so many hours in the day and that when you have someone whos going to high school and theyre at school from 8 oclock to 2 oclock, or to 3 oclock, and then theyre at practice for a couple of hours and they need time to study, they need time to eat, they need time to commute back and forth to school and practices, they need time to sleep, DiFiori said. They need time to recover. Its important that people actually look at that and realize that you cant pack everything into one day and still necessarily have a healthy situation.The guidelines suggest limiting high-density competition, such as tournaments that feature multiple games in a short period of time.DiFiori noted the guidelines apply only to organized competition, saying that individual practice time or pickup games are beneficial. They have been endorsed by numerous youth organizations, athletic apparel companies and supported by the NCAA.Were sending a message to families, young athletes, coaches about rethinking how we do things at the youth level, he said.Alex Reyes Jersey . -- Teemu Selanne scored the first goal of his 22nd NHL season, and the Anaheim Ducks extended the best start in franchise history with their fifth straight victory, 3-2 over the Calgary Flames on Wednesday night. Keith Hernandez Jersey . The Vancouver coach and an announced sellout crowd of 18,910 watched in dismay as the Canucks lost 7-4 to the New York Islanders on Monday night by squandering a 3-0 lead in the third period. https://www.cheapcardinalsonline.com/394t-john-gant-jersey-cardinals.html . Didier Drogba gave away the penalty that put Senegal one goal away from a major upset, but the veteran striker will get another chance -- probably his last -- at the World Cup after Salomon Kalous injury-time strike sealed the Ivorians place in Brazil next year. Whitey Herzog Jersey . The Vikings announced Thursday that Priefer will be one of seven holdovers from the previous staff, along with offensive line coach Jeff Davidson, wide receivers coach George Stewart and others. Norv Turner will mark his 30th year of coaching in the NFL as the offensive co-ordinator, as widely reported for weeks, and George Edwards will be the defensive co-ordinator. Mike Matheny Cardinals JerseyWorld No. 1 Jason Days place in the lucrative season-ending Tour Championship is in doubt after he withdrew with a back injury from the BMW Championship won by Dustin Johnson.Day tweaked his lower back when he bent down to put a tee in the ground on the ninth hole and decided to pull out of the event rather than risk further damage.Already well back off the lead, he now has a serious challenger for his place at the top of the world rankings as world No.2 Johnson powered home to win at Crooked Stick Golf Club by three shots.Johnson shot a final round five-under 67 to surge to 23 under for the tournament, winning for the third time this year to go with his US Open and WGC Bridgestone Invitational triumph.Englands Paul Casey finished runner-up for the second week running, closing with a 67 of his own to be 20 under, with American Roberto Castro (67) playing his way into the season finale by finishing third at 17 under.The results puts the American closer to Day in the world rankings ahead of the season ending Tour Championship, and sends him to the top of the season long FedExCup points list.Defending event champion Day has a history of back issues, withdrawing from the BMW Championship in 2014 with a similar complaint.He also battled a bad back at the 2015 Barclays and 2016 World Golf Championships Match Play with the same issue before fighting through the pain and winning.His place in Atlanta in two weeks is now in doubt where the winner of the season long FedExCup will claim a $US10million bonus.Hes all right, hes just got some back iissues and is in a little bit of pain.dddddddddddd Hes getting treatment right now. I dont think its anything that he hasnt dealt with before, Days manager Bud Martin said.The trainer is maybe thinking its the same type of thing that he dealt with I think at the Barclays and last year where he picked something up in his bus and it kind of got out of line.But just better safe than sorry. Instead of forcing it, we just decided that it was more prudent to kind of come in, get it worked on, and deal with it.Day dropped from second to fourth in the FedExCup standings which is of minimal consequence as those in the top five can guarantee the FedExCup with a win in the TOUR Championship.Well probably get a MRI just to double check. My gut is that hell be fine, Martin said.Hopefully, hell be ready for Atlanta, but the most important thing is the next 15 years, not the next 15 days.Meanwhile Adam Scott finished fourth for the third straight playoff event.A final round 71 left him 12 under, 11 shots off the win. He is now third in the season-long points list, giving him a chance to win it all in two weeks time.Hopefully Im saving my best for last, that would be a great way to finish the year, Scott said.And starting in third, that would mean I would win the FedExCup. So thats an exciting spot for me to be in and hopefully I can take advantage of it.Marc Leishman (-1) and Aaron Baddeley (+4) have ended their seasons. ' ' '
