At the end of the 8 week training period the researchers reported no difference in strength (1RM), peak power, shuttle-run performance and lean mass between the two groups (both groups had the same improvements).

However – only the circuit group lost significant levels of body fat.

The take home message is that circuit training with heavy resistance can provide the same benefits as a traditional strength training program, with the extra addition of fat loss, all in a shorter time frame.

My interpretation: I think if we had the subjects train for the same amount of time (ie a one hour session) – the differences would be even more dramatic. A circuit training group does the same volume in less time than a traditional group, so in the real world where clients could show up for the same amount of time, it only makes sense to recognize that a circuit or superset style of training could allow us to do MORE work than a traditional routine.

I think training with fat loss or general fitness as your goal is probably best accomplished by using reciprocal or non-competing supersets, or in a circuit format to maximize work density. This study shows that it may be as effective even if your goal is improved strength or power.
