sorry RADAR but have to disagree with you there
i think the statement running burns muscle is missleading, but also ur running wont burn muscle unless in a calorie defeceit is also incorrect
there are many factors that effect what running burns, e.g time running, intensity, diet, muscle size etc
a more muscular person is suseptable toi muscle loss while running since his calorie usage is higher, and therefore burns his carb stores faster, after which the body actually generally can turn to muscle as a primary energy source
its been shown that running at different intensitys can effect the body use of fat stores, usually between 10-40% of its energy will come from fat, muscle is also used even before gylcogen stores are depleted
running also raises cotisol level which are catabolic to muscle, aswell as increase other gluco steroids which prevent inflamtion, but also burn muscle once again
testerone levels also generally fall during intense running, so the enviroment present isnt the best for muscle preservation
however generally its longer distance running that leads ot muscle loss, since glycogen stores become further depleted aswell as testerone level fall furthr, aswell as gluco steroids raise heavily for long periods of time
short burst running, or intense short burst of running generaly have very little effect on muscle catabolism since it generally wont deplete the body, aswell as maintains a different muscle fiber compostion to longer distance running
so running can be very catabolic to muscles, it all just depends on how you run
thid id sldo why steroids are so benefical for fat burning, they maintain a perfectly anabolic enviroment when intense exercise becomes present
when the bodys test levels are usally falling and gluco steroids are rising, anabolic steroids can maintain high levels of test, and block glucosteroids catabolic effect on muscle mass

just make sure you go a little bit further everyday like a light post or use land marks where you run.
