Was doing some lunch time browsing, thought I would post this, from,

Effect of an acute period of resistance exercise on excess post-exercise oxygen consumption (EPOC): implications for body fat management.
Eur J Appl Physiol 2002 Mar;86(5):411-7
This group looked at the effects of circuit weight training on EPOC.
The exercise routine consisted of three exercises (the bench press, the power clean and the squat), performed with 10RM loads as a circuit. The circuit was performed four times (i.e. twelve total sets) and took 31 mins.
EPOC was elevated for 38 hours post workout (possibly longer as this was when the researchers stopped measuring). The duration and magnitude of the EPOC observed in this study indicates the importance of the role of high intensity resistance training in a fat loss program.
Also, a quote I picken up on the PN forums which i really like,
"Caring how much fat is burned during training makes as much sense as caring how much muscle is built during training."
