The Cumbrians ended the 2012/13 campaign in 17th place and began their summer business with a clearout of seven first-team players.
In their place, Abbott wants to find signings blessed with pace as he looks to alter United's style of play.
"I think we need some real energy and pace in the team to put teams on the back foot," he told the Carlisle News & Star.
"When all else is wrong, you are looking to stick the ball out to the wide players who can go by people, or even down the middle to run onto a ball over the top.
"We haven't got too many players who can stretch the game. That has been evident over the season."
