The 26-year-old double amputee has not raced competitively since he was arrested and charged over the killing of his girlfriend Reeva Steenkamp in February.
Speculation over a possible return to action has been rife for some time as the South African awaits trial and in a statement posted on his website yesterday, it was confirmed he would commence a reduced track programme.
"Oscar has decided to resume a low-key track routine," the statement read.
"Oscar is not contemplating a formal return to athletics and his training is not aimed at preparing for competition.
"His focus at this time remains entirely on the court case.
"His family, and those close to him, have encouraged him to spend a few hours a week on the track to assist him in finding the necessary mental and emotional equilibrium to process his trauma and prepare for the trial."
The Paralympic sprint champion is accused of murdering Ms Steenkamp, a 29-year-old model and law graduate, on February 14.
The athlete has said he shot Ms Steenkamp through a bathroom door thinking an intruder was inside his house.
He was granted bail on February 22 but returned to court for a pre-trial hearing on June 4, when prosecutors requested a postponement to allow for further investigation of the case.
The hearing has been postponed until August 19, with a trial expected later this year or in early 2014.
Pistorius won gold at the London 2012 Paralympics and became the first double leg amputee to participate in the Olympics at the London 2012 Games after a long legal battle.
