Following the controversial dropping of a number of events for Rio 2016 by the International Paralympic Committee (IPC) last month, British record holder Nobbs has been forced to switch events as the F54/F55 and F56 shot put competitions have been dropped in favour of a single-class F55 event, which does not present the man from Norfolk with a realistic chance of qualification for the Games in Rio.

"I will be competing against guys with a similar disability on a level playing field," said Nobbs, who finished tenth in the shot put event at Beijing 2008 but failed to qualify for last year's Paralympics after a change in the regulations for throwing frames affected his performances.

"Hopefully I'll be in with a good chance when I can master the technicalities and be up there with the big boys.

"If I stuck with the F55 I would be competing against guys with full abdominal and back muscles, which I haven't got.

"We made the decision that in the four-year period to Rio the javelin was the event I could hopefully make the biggest gains in and hopefully get selected for Team GB."
