Kieron Dyer has revealed that a "special training programme" has been a major contributing factor behind his return from injury this season.

The Queens Park Rangers midfielder has missed large amounts of football during his career because of a succession of different complaints.

However, he is yet to miss a training session with the R's this season and the former England international is confident that he can continue that trend for the remainder of the season.

"I have been put on a special training programme and I haven't missed a session this season so it must be working," he told the London Evening Standard.

"There is a lot of sport science involved. We take saliva and urine tests in the morning and if my saliva test is a bit high, they pull me out of training or modify it. They take a swab and it can tell you if you're feeling stressed and if your body is not 100% right.

"My sessions are all high intensity. In the past I have been coasting in training because I wanted to save myself for the match. Now I train like I am in a game."

Dyer joined QPR on a free transfer from West Ham United last summer.
