The study was small, involving 69 teens treated at a University of Pittsburgh Medical Center concussion clinic, but the results bolster evidence supporting the growing number of return-to-play laws and policies nationwideThe study was published Monday in the journal Pediatrics.KEEPING SCOREThe study involved athletes aged 15 on average from several sports, including football, soccer, ice hockey and basketball who had concussions during a game or practice. Half continued to play and took 44 days on average to recover from symptoms, versus 22 days in those who were immediately sidelined.Sidelined players reported symptoms immediately, including dizziness, headaches, mental fogginess and fatigue, and were diagnosed with concussions by trainers or team physicians. The others, who continued playing for 19 minutes on average, delayed reporting symptoms and were diagnosed later.Those who continued to play had worse scores on mental function tests performed eight days after the concussion and 30 days after the concussion. Medical records showed mental function had been similar in all players before their concussions.RISKY RETURNSReturn-to-play policies are widespread, especially in youth athletics, and they typically recommend sidelining players after a suspected concussion until symptoms resolve. One of the main reasons is to prevent a rare condition called second-impact syndrome -- potentially fatal brain swelling or bleeding that can occur when a player still recovering from a concussion gets hit again in the head.The study results show that a prolonged recovery is another important risk from returning to play too soon -- one that no one had really calculated until now, said Dr. Allen Sills, a Vanderbilt University neurosurgeon. He was not involved in the research.NOT REPORTEDAbout 300,000 sports-related concussions occur each year nationwide among all ages. In high school athletics, they occur at a rate of almost 3 per 10,000 games or practices.Evidence suggests up to 50 percent of concussions in teen sports arent reported. Athletes are sometimes not aware theyve experienced a concussion, or they suspect a head injury but continue playing because they dont want to let their teammates down, said University of Arkansas concussion researcher R.J. Elbin, the studys lead author.The results give us more ammunition to persuade young athletes to heed the return-to-play advice, Elbin said.---Online:Pediatrics:

Western Sydney coach Tony Popovic has hinted at a first A-League start for marquee Nicolas Martinez in Fridays grand final re-match against Adelaide.Popovic was impressed with Martinez 30-minute stint off the bench in round one, despite the Argentine midfielder flaming out late.In the last 10 minutes, he probably found it a bit tough physically with the lack of training and game time hes had, Popovic said.But for that 15-20 minute period when he first came on, you can see the quality he has on the ball. His movement off the ball, you can already see some combinations building in our front third.Its that kind of quality that could tempt Popovic to start Martinez against the Reds and form an intriguing midfield that includes fellow import Jumpei Kusukami and Mitch Nicholls.Popovic insisted on attempting to take a long-term approach with the former Olympiacos player, saying there was no need to rely on Martinez too early.We want Nico available all season. To throw him in and start that game in the derby ... hes got more of a chance tomorrow, Popovic said.But its about having him being able to reproduce week by week, at training, in games and having him available because hes a very good player.The Wanderers coach was also delighted with the first outing of Kusukami, who was easily Popovics most-dangerous threat against Sydney FC.The former J-League player liit up ANZ Stadium with a number of slicing runs, and was on target with both of his shots on goal.

He showed against Sydney FC in such a big game, especially in a moment where we were behind on the scoreboard, he really tried to step up and get us back in the game, Popovic said.Theres a lot more to come from him, but were delighted to have him at our club.Its the defence that could be of concern for Popovic, who has given captain Nikolai Topor-Stanley permission to pursue an overseas opportunity and another defender in Artiz Borda suspended.The Wanderers will have to overcome a poor record against the Reds in recent years, having won just one of their past nine clashes and none in five matches in Adelaide.Reds defender Iacopo La Rocca expected Popovic to extract plenty of fight out of his old club.I know Poppa - I know he will push the team. Of course, they will come here to get the three points, but we play at home - we have the advantage, he said.STATS THAT MATTER:* Adelaide have only conceded two first-half goals across their past 11 matches* United have only tasted defeat once in their past 22 A-League matches (W16, D5)* The Wanderers have conceded at least three goals in each of their past three A-League games
