"Comparison of Aerobic Versus Resistance Exercise Training Effects on Metabolic Syndrome"

Interesting result:

"...In conclusion, [resistance training] was not effective at improving the [Metabolic Syndrome] score; however, [aerobic training] was effective. Combined [aerobic training] and [resistance training] was similarly effective but not different from [aerobic training] alone. When weighing the time commitment versus health benefit, the data suggest that [aerobic training] alone was the most efficient mode of exercise for improving cardiometabolic health...."

Seems to me that both are necessary for a healthy system, but it's very interesting that only aerobic training offered benefits to sufferers of Metabolic Syndrome. 

Phil Maffetone says that resistance training primarily uses the anaerobic system, which, of course, is glucose-based.  This would seem to support that, and also to support the notion that a fat-burning metabolism is healthy to victims of the Modern American Diet.  Although Maffetone also cautions against resistance training because it impairs aerobic function, whereas here it didn't seem to...
