Up to quite recently, all the Caribbean sprinters were hoovered up by the US universities on sports scholarships. Places like Louisiana State based their successive national titles in track and field on recruiting West Indian athletes. It was a recognised way out of poverty. Unfortunately few returned So, recently they have established a sports scholarship program at the Jamaican Technical University, but it is woofully underfunded, with poor facilities (grass track) but with some good coaches.
However the athletes they have produced has been exceptional and this has raised a few eyebrows as they seem to be doing better than the Jamaican athletes who are chosen (often as a fist pick) to still go to US universities. Also many are worried that the US university based athletes from the islands also seem to make huge performance gains when they return home for winter warm weather out of season training. In fact, significantly better than similar standard athletes who go to Mexico with their university program and stay under the auspices of the US drug monitoring system.
It's why WADA's recent 'targeted' drug testing system has been dogging the Jamaicans since their arrival in Beijing. But it' too late to catch sprinters who favour steroid use at the conditioning / strength training phase well before competition.
