Buttifant, who crossed to the Blues from Collingwood in the off-season to reunite with coach Mick Malthouse, is currently leading Carlton on a two-week camp in Arizona.
The high performance manager said there was only a limited window during the pre-season to condition players and high-altitude camps fast-tracked the process.
"We don't have a huge amount of time to get those very strong training adaptations that we're after," Buttifant told carltonfc.com.au.
"At the elite level if you can get two or three per cent change, you take that.
"We know the benefits, now the research is quite validated in having a positive outcome towards performance.
"We need to fast track their conditioning over the pre-season period."
Buttifant defended high altitude training in the wake of some criticism within the industry, saying the programs he pioneered provided “unequivocal” results.
Malthouse also hit back at critics of high-altitude training on Monday, declaring Carlton wouldn't waste time or money on an exercise that wasn't proven.
Carlton travelled to Arizona ahead of the 2013 season and Buttifant said the players were well aware of the benefits.
