Yes, quite surprising isn't it? However, look into the link I provided and also consider this:
Cardiovascular activity --> stimulation of type I (endurance) muscle fibers --> increased conditioning, less hypertrophy, less mitochondria* (relational)
Resistance training --> stimulation of type II (there are multiple types but I am trying to simplify) --> increased hypertrophy, increased overall mitochondria*
The Rationale for increased cortisol in the former activity lies in mitochondrial concentration (of which is decreased in cardiovascular acitivity). Decreased Mitochondria equals Increased Fat (or less fat burning which is likely a better way to look at it). Increased Fat equals Increased Cortisol Secretion.
put aerobics head to head in studies with weight training. The results: aerobics was INDEED effective for helping guys slim down - BUT much of the weight was shown to be MUSCLE MASS - so now, they tended to include (with less mitochondrial concentrations) metabolic SLOWDOWN - depsite "weight" loss. Once they stopped the actual exercise, their bodies no longer had to provide fuel for as much musculature. Now, the 200 pounder who slimmed down to say 165 had a slower basal (resting) metabolic rate than a guy who'd been 165 pounds his entire life! Now, how could this less musculature figure keep his new 165-pound physique .... easy: eat less, problem: he'd have to eat less and less and less as more and more muscle would dissipate. Who's capable of that kind of discipline? This guy is gonna have a huge weight regain, but now with his newly-incorporated lower BMR coupled with a higher cortisol rate.
What's it mean:
The potentially musculature man is gonna be a bit more....uhhhhh, flabby.
