Earlier reports said the International Association of Athletics Federations (IAAF) has banned athletes swapping nationality.

BBC Africa Live report continues:

More than 20 Kenyan-born athletes represented adopted nations in Rio on track events. 

Here are a few of the countries the Kenyan athletes have competed for:

Bahrain

Bahrain's Olympics team's ex-Kenyans is led by steeplechase record holder Ruth Chebet, who is also World Junior Champion. 

The 20-year-old won gold at the Rio Olympics in the 3,000m, breaking the world record. He broke the world record again a week later in the Diamond League.

Others who competed for Bahrain included:

·    Abraham Rotich (800m)

·    Benson Seuri (1,500m)

·    John Koech (3,000m steeplechase) 

·    Albert Rop (5,000m)

·    Rose Chelim (marathon) 

·    Eunice Kirwa (marathon) 

·    Eunice Chumba (marathon)

The US fielded ex-Kenyans led by veteran Bernard Lagat who, at 41, became the oldest American to compete on the track at the Olympics. 

He ran in the 5,000m race. Lagat competed for Kenya at the 2000 Olympics in Sydney and the 2004 Olympics in Athens before switching nationalities and representing the US at the 2008 Olympics in Beijing, the 2012 Olympics in London and the 2016 Olympics in Rio.

Other former Kenyans who competed in Rio included people serving in the US army:

·   Paul Chelimo (5,000m) 

·   Hilary Bor (3,000m steeplechase) 

·   Shadrack Kipchirchir (10,000m)

·   Leonard Korir (10,000).

Turkey

Turkey’s Kenyan imports included European 10,000m long distance running champion Yasemin Can, born as Vivian Jemutai, Obzbilan Kaan Kigen, born as Mike Kipruto Kigen and Ali Kaya, formerly Stanley Kiprotich Mukche.

Other Kenyans  in Turkish colours were:

·   Tarik Langat Akdag (steeplechase)

·   Polat Kemboi Arikan (steeplechase)

·   Ilham Tanui Ozbilen (1,500) 

Bosnia, Qatar and Azerbaijan

Lucia Kimani-Marcetic represented Bosniain the marathon. 

Qatar - the nation which pioneered importation of Kenyan athletes, starting with world steeplechase record holder Said Saeed Shaheen (formely known as Stephen Cherono) - was represented in Rio by ex-Kenyan Essa Ismail Rasheed (formerly Daniel Kipkosgei) in the marathon. 

He has competed for Qatar for the last 12 years and won the 10,000m gold medal at the 2005 Asian Championship.

Perhaps the most surprising swap in Rio was that of Evans Kiplagat Chebet who represented Azerbaijan in the marathon. Kiplagat has lived in Azerbaijan since April 2015 and acquired Azeri citizenship a year later.
