RIO DE JANEIRO -- The winds of change are blowing at the Rio badminton arena. Actually, those are just the gusts from the air conditioning vents: Theyre cold and theyre strong and they could pose a problem for some of the best players on the planet.After all, Olympic glory will be determined by a few feathers -- more precisely, by the flight of the 16 goose feathers stuck to the light, leather-covered round cork of the shuttle.Badminton players call these winds drifts, caused by strong air conditioning and currents that arise when hot, humid air enters from open doors and meets colder air inside an arena.Drifts can swirl in from the side, above and below. They can stop and start or blast away steadily, and do funny things to a badminton shuttle, spinning it out of a rackets path or causing a shot that should have landed in to land out.Simply turning off the air conditioning doesnt work because sweat -- on the racket, in the eyes, on the floor -- can be as big a problem as drifts.No venue is perfect, and theres no way to completely kill drifts, although players change sides during a match to try to compensate. Gripes about drift are part of badminton, even at the last Olympics in England, where the modern version of the game was developed in the 19th century.One complaint in Rio is that the multipurpose Riocentro pavilion where the badminton matches are being held wasnt built with the sport in mind. Dedicated badminton stadiums, like the ones the superstars are used to playing in, usually do a better job dealing with drifts, placing AC vents and doors in a way that minimizes air currents.Players say the drifts in Riocentro change depending on which side of the court they play on. Drifts also vary from court to court, with some saying the middle of the pavilions three courts is worse than the side courts.Experience might be the best antidote to drifts.Veteran players, especially those who play the professional tour in Asia, where heat and humidity often mean high AC in the stadiums, tend to handle drift better.They compensate for it, they get used to it, Estonian Raul Must, world No. 45, said after a loss to Jan O. Jorgensen, the world No. 5, from Denmark. The drift made it harder for me. One side, it was slow; the other side was faster. So it can be one meter shorter than what you think on the slow side, and one meter longer on the other side.Others also acknowledged the drifts in Riocentro, but noted that everyone had practiced in the venue for days before the competition started and so knew how to adjust to the bad spots.Perhaps the best strategy for drifts? Just dont think about them.I would be lying if I said it wasnt a factor. It is, but its the same everywhere, Jorgensen said. I dont want to worry about something that I cant control a single thing about.Drift is much more of a factor when top players face each other because the margins of error between the elite are so narrow, said Soren Opti, a 19-year-old from Suriname who was crushed early on by world No. 1 Lee Chong Wei, of Malaysia.The drifts in Rio were tough but by no means the worst hes seen, said Opti, ranked No. 318 internationally.During one tournament in the Dominican Republic, he said, a passing thunderstorm was so strong that rain leaked inside from the arenas roof.When I hit the shuttle, it would blow back at me, Opti said.---Follow Foster Klug at www.twitter.com/apklugNike Air Force 1 Australia Cheap .

Victorino is batting sixth and playing right field after missing two games because of back tightness.Olympic legend Michael Johnson has backed Australian swimmer Mack Hortons right to call out drug cheats at the Rio Games.Johnson, who won four Olympic gold medals on the track and still holds the 400m world record, says athletes like Horton should do what they feel they need to do.Some of the athletes feel that they need to raise their concern with the public, he said.They feel that they have no other choice and they feel that theyre competing against athletes that have had doping issues in the past.I think that they have every right to do that and I dont think that anyone should tell them that they shouldnt do that or that they cant do that.Horton sparked controversy when he won the 400m freestyle gold medal on Saturday night, defeating Chinas Sun Yang, and then dismissed his rival as a drug cheat.Sun, who served a doping suspension in 2014, won the 200m freestyle gold medal on Monday night.Chinese Olympic officials have demanded an apology from their Australian counterparts - a request flatly rejected.US swwimming star Michael Phelps followed Hortons lead by also criticising the presence of drug cheats in Rio.ddddddddddddTo have somebody test positive not just once but twice and still have the opportunity to swim at these Games, it breaks my heart, Phelps said.I wish somebody would do something about it.Phelps was directly referring to Russian swimmer Yulia Efimova, who won a silver medal in the womens 100m breaststroke on Monday night.Efimova was beaten by American Lilly King, who also said the Russian shouldnt be at the Rio Games.Efimova said she understood Kings attitude towards her, but added the American didnt know all the facts.In Rio to support the Los Angeles bid for the 2024 Olympics, Johnson also backed calls for tougher sanctions on drug cheats, including a suggestion from IOC president Thomas Bach that athletes with two drug penalties should face a mandatory Olympic ban.
