The England Under-21 international has dropped down to the Championship in search of first-team football and he claims that he already feels physically stronger
Ameobi, 20, made eight Premier League appearances for Alan Pardew's side as well as an extra five in the Europa League, but is certain his experience in the Championship will stand him in good stead.
The England under-21 international has played three times for Tony Mowbray's ninth-placed team as they look to make a late push for the play-offs and he already believes he can feel a physical difference.
"I've already taken a lot from the games I've played, and I'm stronger physically," he told the Evening Chronicle.
"Hopefully, I can bring that back to Newcastle. Middlesbrough are trying to get in the play-offs, and I'm trying my best to help the club do that.
"It's not easy. The ball turns over a lot more. There's a lot more running. You have to be strong, but I'm enjoying every minute of it. It's going well. I'm glad to be getting some games under my belt.
"I'm feeling part of the team. Hopefully, I'll continue getting games and impress the manager. Games are what I need for my confidence and development as a player.
"I'm playing week-in, week- out, and keeping my fitness levels on. Hopefully, we'll get that play-off spot. And Newcastle are doing great right now, especially in Europe."
