body motives?

fuscia · 05-17-2007

i'm wondering about a reason behind the body's reaction to several different types of exercise: sarcoplasmic hypertrophy, in response to the 'bodybuilder' (or, should that be booby builder?) workout, the catabolic effect that can occur in some distance athletes, and the retention of fat in some swimmers. while i did stay at a holiday inn express last night, i have nothing more than an enthusiastic fan's knowledge of physiology, so, i might get a lot of this wrong.

from what i've read, the bodybuilder's workout causes sarcoplasmic hypertrophy, which is an increase in the fluid of the muscle. as most bodybuilding schemes involve an 8-12 rep scheme to failure, i'm wondering if the increase in the sarcoplasm creates a hydraulic benefit making this type of exercise easier on the body.

ever look at marathon runners? the good ones are all scrawny. they're not just low fat, they're also low in muscle. supposedly, this is due to a catabolic effect, which is the breaking down of tissue into smaller units (someone stop me before i throw another shovel full on the pile). anyway, in this case, i'm wondering if the body knows it will do better in a marathon if it is lighter, even if it has to dump some muscle.

i've read, in various places i no longer remember, that swimming is not the best exercise for losing fat. several reasons are given for this, including everything from it being primarily an upper body exercise to people just sucking at it (i don't know if any of that's true. i pretty much stick to canonballs and playing shark). another explanation i've heard is that the body retains fat so as not to lose heat energy to the water. wtf? why would that happen in a heated pool? does the body assume all water is cold? if there is a body scheme going on here, i have this unsupported theory that the body retains fat because it is more boyant, not because it's worried about heat loss.

well?

anyone remember this guy?
