Jackson won two gold and two silver Commonwealth medals

A Welshman failed to win a track medal at the Games for the first time since 1950, while the women got just one.

"These athletes are very talented and they should be on the rostrum, but you only get what you deserve," said former 110m hurdle champion Jackson.

"We've got four years to get it right. It's a great opportunity to re-assess and look at their own performances."

Wales' failure in Melbourne was mirrored by the other home nations as the UK brought back just 23 track and field medals.

Host nation Australia won 41 - with 16 of those golds.

Jackson believes a fresh approach is needed across the board to ensure future successes.

"Athletics is the dominant sport in the Commonwealth Games, as in the Olympic Games, so you always want to shine on the track," Jackson told BBC Wales Sport.

"It's been a very long time since Wales failed to win a men's track medal. And being someone who has won a medal in the past, I know how important it is.

"It's a questioning time for us all. And if you look on the UK generally, the medal tally wasn't as strong as it could have been.

"Perhaps we have to re-assess the whole way we approach way we approach the Commonwealth Games, the other championships and basically all type of racing."

Wales' newly appointed performance director Jeremy Moody said athletics is currently going through a "period of change".

But he said the future prospects for Wales are encouraging with a "lot of talent that can be pushed forward for future events".

Moody added: "There will be a major focus on working with coach and athlete pairings and making sure the support services that are required are delivered and are at the highest level.

"I don't think attitude is a problem, and if it is, I'm sure there are things afoot to try to stop that.

"The bottom line is if the attitude isn't right, you won't get compete at world level to begin with."

Jackson suggested Wales need to get more athletes on the Grand Prix circuit.

He said: "They've got to get out there and race against the people they'll be up against at the major championships.

"That takes away a bit of that fear factor. But it's a chicken and the egg kind of scenario because unless you run fast you can't get on the circuit.

"But train hard, work well and they will achieve their goals. We're not asking for impossibilities from them because these are very talented athletes."
