6/29    Why do muscles swell during a workout? I don't understand the benefit
        or the method (ie, how do the cells suddenly become hypertonic to the
        rest of the body?)
        \_ besides "looking good", what are some actual physiological
           benefit of working out? Wouldn't aerobic excercise be better than
                is the pump.  Your muscles get filled with blood." -Arnold
           just pumping out?
           \_ there is no benefit to being a pumped up monster.  however,
              being in good cardiovascular condition and being generally
              toned and strong is just good health.
           \_ Well, what do you mean by "better"?  If you're trying to lose
              weight, doing both is good, because the more muscle mass you
              have, the more calories your body's burning just sitting
              around doing nothing.  Cardiovascular exercise itself actually
              burns more calories while you're doing it, of course.
           \_ In some sports such as football and basketball being big
              and strong can be a significant advantage.  Also, being big
              helps prevent injury (assuming you don't lose flexibility).
                \_ The blood does go to your muscles, which leaves less in
                   your veins.  Your body compensates by adding water to your
                   bloodstream, which can cause you to get incredibly thirsty
              Finally, if you're scrawny people tend to pick on you, while
              if you're buff, everyone acts friendly.  Once you finish
              high school this isn't as big a deal, though.
              \_ Only if you goto a nerdy school like cal surrounded by
                 nerds. Otherwise at other schools, it's almost the same
                 (except you dont get physically picked on).
                 After that, it's almost the opposite. The big hulking
                 guys cant get a good job, but the scrawy ones with brains
                 do an IPO and get rich and then everyone acts friendly.
                 \_ Keep dreaming, wimp.

        \_ blood
                \_ "The first thing you notice when you begin to work out
                    is the pump.  Your penis get filled with blood." -Arnold
                \_ The blood does go to your penis, which leaves less in
                   your brain.  Your body compensates by adding water to your
                   bloodstream, which can cause you to get incredibly horny
                   very quickly.
        \_ when you work out, you use up oxygen more as respiration process
             to produce ATP.  Most likely, when the oxygen level of your
             blood stream lowers, a negative feedback pathway will
             increase the heart beat rate to pump more blood (thus
             oxygen) into the circulatory path way.
