Countdown to Rio 2016: Olympic sport this week
ADAMS ON TOP OF THE WORLD
Boxing: Great Britain's Nicola Adams completed her full set of international titles with a flyweight gold medal at the World Championships in Kazakhstan.
The 33-year-old, who had already qualified for Rio, added the world title to her Olympic, Commonwealth, European and European Games crowns by defeating Thailand's Peamwilai Laopeam in Astana.
Middleweight Savannah Marshall booked her place at this summer's Olympics by reaching the semi-finals.
Ireland's lightweight Katie Taylor also clinched her spot at the Games in Rio but fell short of a sixth consecutive world title after losing her semi-final.
FARAH ON FORM WHILE KJT HITS TARGET
Athletics: Olympic champion Mo Farah said he was "kind of disappointed" despite running the third-quickest time of his career to win the 10,000m at the Diamond League meeting in Eugene, Oregon.
The 33-year-old, who ran 26 minutes 53.71 seconds in his first track race since the 2015 World Championships, added: "I was hoping to run a lot faster".
Justin Gatlin won the 100m in Oregon in the fastest time this year - a wind-assisted 9.88 seconds - to beat Jamaica's Asafa Powell and fellow American Tyson Gay.
British heptathlete Katarina Johnson-Thompson qualified for the Rio Olympics, finishing with 6,304 points in coming sixth at the Hypo-Meeting in Gotzis, Austria. The event was won by world silver medallist Brianne Theisen-Eaton.
But there was disappointment for Ashley Bryant, who fell just short of the qualifying standard after competing with borrowed equipment when his own went missing.
WILSON FLYING HIGH
Gymnastics: Nile Wilson became the first Briton ever to win gold on the high bar at the European Championships in Switzerland.
The 20-year-old from Leeds edged out team-mate Kristian Thomas in Bern by scoring 15.3 on the last routine.
It was a second medal of the championships for both gymnasts, who also won silver in the team event as Great Britain - despite being without the ill Max Whitlock - finished behind Russia and ahead of hosts Switzerland.
The event in Bern is the last major competition before the Rio Olympics team is announced on 12 July.
GB FOUR STRIKE GOLD
Rowing: Great Britain's men's four overhauled Australia in the final two strokes to edge to a thrilling victory at the World Cup in Lucerne.
The gold was one of four medals won by British crews, including an impressive silver from the women's eight, whose line-up could yet be rejigged with Katherine Grainger and Vicky Thornley looking for a boat after their double partnership was dissolved.
There was also silver for the men's quadruple and bronze in the men's pair. Helen Glover and Heather Stanning, Britain's strongest hope for gold in Rio, had to withdraw from the women's pair after Stanning was struck down by an overnight bug.
Earlier in the week in Lucerne, in the final Olympic qualifiers, Great Britain failed to book spots in the women's singles and women's quad, meaning they will have boats in 12 of the 14 rowing classes in Rio this summer.
DRUG RETESTS PRODUCE POSITIVE RESULTS
The IOC have announced that 23 athletes from five different sports and six different countries at the 2012 Olympics have failed retrospective doping tests.
In addition, 32 athletes failed tests when samples from the 2008 Games in Beijing were retested.
The positive tests could lead to bans being handed down before the Rio Olympics.
The Russian Olympic Committee says eight of its competitors were among the 23 positive results from the London 2012 retests.
NEWS IN BRIEF
Archery: Northern Ireland's Patrick Huston qualified for the Olympics by finishing in the top three of the European Continental Qualifier in Nottingham.
Great Britain's men's team lost a gold-medal shoot-off to Russia at the European Championships later in the week in Nottingham but Huston took bronze in the individual event. The GB women's team lost their bronze-medal match to Germany, with Ukraine taking gold.
BMX: Britain's former world champion Liam Phillips failed to make the final at the World Championships in Colombia, going out at the semi-final stage. The men's title was won by Joris Daudet of France, with Colombia's Mariana Pajon winning the women's event.
Canoe sprint: Britain's Liam Heath claimed gold in the K1 200m at the World Cup in the Czech Republic. Heath also teamed up with Jon Schofield to take bronze in the K2 200m final. Britain's Olympic champion Ed McKeever was fifth behind Heath in the K1 200m.
Equestrian - jumping: Veteran John Whitaker's flawless final round on Ornellaia ensured Olympic champions Great Britain won the FEI Nations Cup in Rome for the second year in a row. Whitaker's younger brother Michael, Ben Maher and Jessica Mendoza made up the victorious quartet.
Hockey: World number one team Australia comfortably defeated Great Britain's men 5-1 in Perth to complete a 2-0 series win.
Judo: Britain's Natalie Powell beat British rival Gemma Gibbons on her way to bronze at the annual Masters event in Mexico, ensuring her Olympic qualification at the expense of the London 2012 silver medallist. Only one judoka per nation is allowed in each weight category, and Commonwealth champion Powell has ended the qualification period with more ranking points than Gibbons.
Modern pentathlon: In-form Briton Jamie Cooke secured an Olympic quota place by finishing ninth at the World Championships in Moscow as France's Valentin Belaud clinched the gold medal.
A poor performance on the shooting range cost former world champion Samantha Murray the chance of a medal in the women's event. She slipped from fourth to 16th in the concluding run-shoot, with Hungary's Sarolta Kovacs securing a maiden individual world title.
Mountain bike: Britain's Grant Ferguson, who achieved a career-best 15th at last week's World Cup leg in Germany, was forced to retire from this week's leg in La Bresse, France, which was won by former Olympic champion Julien Absalon.
Road cycling: Italy's Vincenzo Nibali clinched his fourth Grand Tour title in winning his second Giro d'Italia.
Rugby Sevens: Australia won their first Women's Sevens Series title, ending the three-year reign of New Zealand. England, who will comprise the majority of Great Britain's team for the 2016 Olympics, finished fourth after the five-leg series finished in France.
Tennis: Maria Sharapova has been named in a four-strong Russian squad for the Rio 2016 Olympic women's singles despite being currently suspended from participating due to her testing positive for meldonium.
Britain's Heather Watson looks set to compete in the Olympics after reaching the second round of the French Open, which will keep her ranking high enough to qualify.
Andy Murray says he is planning on playing in the Olympics but will seek medical advice on the Zika virus situation before making a final decision.
Triathlon: Spaniard Javier Gomez returned to form to win the European title in Lisbon. Gomez is among the favourites for Rio but has barely competed so far this season due to injury. The Brownlee brothers did not compete in Portugal.
Track cycling: British riders looked in good shape in the Coupe de France Fenioux Piste in Paris, the final major track event before the team for the Rio Olympics is announced. World champion Laura Trott beat Katie Archibald into second in the omnium, while Katy Marchant was second in the keirin and Becky James fourth in the sprint.
In the men's events, Callum Skinner was third in the sprint, with Matt Crampton likewise in the keirin.
Zika: The World Health Organisation has dismissed calls from scientists to postpone to 2016 Olympics, saying the Rio event will "not significantly alter" the spread of the zika virus.
