Brad Scott says his team is already reaping the benefits from a high-altitude camp in Utah in November.

The North Melbourne coach says the young Roos' have returned fitter and stronger while taking away some valuable lessons from the experience.

"The reason I was so keen to undertake a camp like that was mainly due to the maturity and the age of our playing group. We really wanted to take them away and educate them on how to live like an elite athlete," Scott told SEN's Tim Watson, Andy Maher and Andrew Gaze on Friday morning.

Since the team returned to Melbourne late last week, training has remained highly intense with the program aimed at fully optimising the gains made at altitude.

"We've made significant improvements in the pre-season already. We were really poor with our ability to run out games (in 2010) and we took a philosophy that we would persist down the path that I was taking the team knowing that it would provide some challenges.

"The benefits won't last all year, but our aim is to have our players return in better condition (from Utah), and then build on those gains through our training."

Premiers Collingwood has seen noticeable improvement from high-altitude camps in previous years and the North Melbourne coach says the similarities between the two sides aren't as vast as people may think, especially in attack.

"I think our forward power is more than comparable with Collingwood's. When you look at Drew Petrie at full-forward, Collingwood use Chris Dawes in that role. Lachie Hansen at centre-half forward; I think he compares very favorably with Travis Cloke, all be it he's a little bit younger.

"There are some similarities in our forward lines and I think that gives our players a lot of confidence knowing that perhaps they are not that far away."

On the comeback trail from injury, Jack Ziebell and Liam Anthony's steady progression has the coach excited.

"Jack Ziebell ran the first time trail on the first day back at pre-season training. He was running like he hadn't broken his leg at all. He participated in all the activities in Utah and looks really fit and strong at the moment.

"Liam probably could have played round 22 but we didn't think it was worth the risk. He's had a really solid training block, and he's looking fantastic."

The pair will be a crucial component in the Kangaroos' midfield next season; an area Scott has targeted since he arrived at the club in 2009.

"There's no doubt we needed to completely overhaul our midfield. There was a glaring weakness with Adam Simpson retiring and a couple of others getting towards the end of their careers.

"Last year we were rapt getting Ben Cunnington and Ryan Bastinac and they were really mainstays in our midfield for the whole year. Not many clubs can say they had two 18 year-olds as mainstays in their genuine on-ball division."

Todd Goldstein was another revelation and the first-time father has already performed strongly on the track, despite being absent form the camp.

"I think he's got the capability to be right in the top echelon of ruckmen in the competition," Scott said.

"Purely on his physical attributes he's certainly a prototypical modern day ruckman. He's an elite runner for someone his size, he's very powerful, he's really good in the centre-bounces with his vertical leap, and he has almost as much impact on games at ground level as he does in the air. He's a unique player. "
