RIO DE JANEIRO -- Imagine a horse race that starts on a ramp about three stories high, then winds down a quarter-mile track with as many bumps and twists as a roller-coaster ride.But instead of riding horses, eight competitors are pedaling frantically on bikes, and the race only takes about 40 seconds.Welcome to BMX racing.The fun at the Rio de Janeiro Games starts Thursday with the mens quarterfinals at the Olympic BMX Center.Youre in this starting gate and its being let out of the gates and everybody goes, U.S. rider Alise Post said. After that youre riding the roller coaster. Everything happens fast out there.But with hills and bumps made of varying heights, and 180-degree turns that riders maneuver on wide, sloping berms.Its really a big kind of a roller coaster adrenaline rush is what it is, said Posts teammate, Corben Sharrah.BMX, which stands for bicycle motocross, traces its roots to Southern California in the late 1960s and early 1970s. An action sport once considered a niche activity is now in its third go-around at the Olympics.It was added in 2008 in Beijing as a way to attract younger viewers with its frenetic, anything-can-happen pace.Even the most seasoned riders still get nervous when they get behind the starting gate.You get on top of that hill when you load the gate and theres always some kind of nerve, said Sharrah, who won the U.S. Olympic trials. He earned the fifth seed in the quarterfinals following the seeding runs on Wednesday .But its a good nerve, Sharrah said. Its kind of that nervous (energy) that feeds what you train for every day.Once cyclists break the starting gate, theyre free to jostle for inside position. Joris Daudet of France, who has the top seed in the quarterfinals, compared a race to a 110-meter hurdle race, but minus the lanes.You can go everywhere you want, Daudet said. Its like a sprint but everyone can change lanes.The competition is Rio is spiced up by a visually appealing track with bright green turns and finely groomed straights with surfaces that look like a baseball infield.The track plays fast, most riders said Wednesday.Its probably the fastest track weve ever had, said David Graf of Switzerland, who is seeded second in the mens draw.American Brooke Crain called the track one of the best that shes been able to ride. She will be seeded seventh when the womens draw resumes racing on Friday.Its just fast, Crain said. The jumps arent terribly big, so its a good racing track.Its still a bumpy ride. The bikes dont have suspension. Crashes arent uncommon.American cyclist Connor Fields isnt fully recovered from a broken bone in his left hand, an injury he sustained in the spring. But Fields, who is seeded fourth, is using a specially designed brace on the hand for the Olympics.What we do is pretty intense to begin with, Fields said. It takes a lot of mental health. You just have to get over that fear and go for it.---Online:AP Summer Games: http://summergames.ap.org/---Follow Genaro Armas at: https://twitter.com/GArmasAPJosh Rosen Cardinals Jersey .

In the response filed Wednesday to the complaint by 30-year-old Alexander Bradley, attorneys say the former University of Florida player is invoking his Fifth Amendment right that protects people from incriminating themselves. An eight-member jury in Los Angeles federal court has found New York Knicks point guard Derrick Rose?and his two friends not liable in a civil lawsuit that accused them of gang-raping Roses ex-girlfriend when she was incapacitated from drugs or alcohol.The jury began deliberations Wednesday morning, and its decision was announced at about 4:30 p.m. ET.I am thankful that the jury understood and agreed with me, Rose said in a statement to The Associated Press. This experience and my sensitivity to it was deep. I am ready to put this behind me and focus on my family and career.Jurors posed for photographs with Rose one at a time in the courthouse lobby after the verdict was announced.One of the two men among the eight jurors who identified himself only by his first name and age, Jared, 25, said the panel tried to look at the case in the plaintiffs favor but in the end could not believe her and felt her tears were not genuine.It felt like she was playing us, Jared said. The second her lawyer started questioning her, she would start crying. I mean, granted, that could be realistic, but I feel lm pretty good at reading people, and I felt as if it was false.Before he ended the proceedings, U.S. District Judge Michael W. Fitzgerald wished all parties the best but added for Rose, Except when the Knicks play the Lakers.Roses ex-girlfriend said he and his two friends raped her in August 2013 at her Los Angeles apartment after she passed out from drugs or alcohol.Neither side denied the three men had sex with the woman, but the issue was whether she consented or was too intoxicated to do so.Defense lawyers painted the woman as a liar who tried to sway jurors through her tears to get at Roses fortune. They claimed she was angry that he had dumped her and that she set him up and brought the lawsuit in hopes of a big payoff.The womans lawyer called the men sexual deviants and said they conspired to rape her after she was drunk and incapable of consenting to sex.Rose was in court, looking down, as the verdict was read. As soon as the first question was answered by the jury, his attorney got up and shook the hand of each of the three defendants.All three men were innocent from day one, Roses attorney, Mark Baute, said. Were very happy that the system worked.The womans attorney, Waukeen McCoy, said he will explore appeal options.I think its a shame for women, for this country, that a celebrity can come into court and slut-shame a woman like my client, McCoy said.Though the accusers reaction could not be seen as the verdict was read, McCoy said she was devastated and did not understand how jurors could reach their conclusion.The woman, who became emotional and trembled while testifying, had sought $21.5 million when she filed the suit, but her attorney did not put a price on the case Tuesday during closing arguments, saying it was up to the jury.Roses lawyer said the future of the Knicks point guard and his whole family was at stake because of a mmorals clause in his player contract and an endorsement deal with Adidas.dddddddddddd.Baute urged jurors to recognize the suit as a hoax and a joke and not even award $20 because that could destroy Roses career and trigger financial ruin for the star and the extended family and friends he had pulled out of poverty from Chicagos South Side with his talent on the court.Adidas, in a statement issued shortly after the verdict was announced, said: Our partnership with Derrick remains unchanged.Lawyers in the civil case sparred for nearly three hours during the bitter closing arguments Tuesday. The womans lawyer said the 30-year-old college student was seeking accountability for what was morally and legally wrong. He said the men had never apologized or shown any remorse and said their behavior was reprehensible enough to trigger punitive damages beyond any compensation.?The three men laughed their way home, McCoy said.The defense portrayed Rose and his childhood pals, Ryan Allen and Randall Hampton, who both work for Rose, as victims in the case, and the lawyers mocked the womans demeanor on the witness stand.This woman has tried to trick people through much of her life, men especially, attorney Michael Monico said. Who is she trying to trick in this courtroom, ladies and gentlemen? You. She doesnt have any evidence, but she can cry.Rose took the stand Tuesday and answered one question about a text message from the accuser with one word: Yes.The juror named Jared said the panel found the three defendants genuine and honest. Jared and the jury forewoman, who wouldnt give her name, said they went through each piece of evidence provided to support the womans case and found nothing added up.I dont want to call her a liar, the forewoman said. I just didnt feel like there was enough evidence.Last summer, the woman also filed a police report along with the civil lawsuit against Rose. The Los Angeles Police Department said it continues to investigate a complaint filed against Rose but said there is no timetable on if or when the criminal case will be closed.Rose is in his first season with the Knicks after being traded by the Chicago Bulls. He has missed five preseason games and seven practices?while attending the civil trial. On Wednesday, Knicks coach Jeff Hornacek said he didnt expect the former league MVP to rejoin the team?until Friday.?Rose is expected to have three full practices with his teammates before the Knicks season opener against the Cleveland Cavaliers on Tuesday.Its a tough thing he went through, but now its over and now we can focus on basketball. I know thats what Derrick wants to get back to doing, Hornacek said. Were just all glad its done with, and now he can get back and focus on basketball.Information from ESPNs Ian Begley and Darren Rovell and The Associated Press was used in this report. ' ' '
