Does Sweating More Mean You�re More Fit?

Sweat is one of your body?s primary means of preventing your core temperature from rising to dangerous levels. During exercise, the majority of the calories you burn actually generate heat instead of powering forward motion (sorry, but that?s just the way it is). In fact, on the bike you are only about 20-25% efficient, meaning 75% of the energy you produce becomes heat. That heat has to be dissipated, so your body dilates blood vessels near the skin to carry some of that heat away from your core to areas where cooler air flowing over the skin can carry away some of the heat. Sweat makes the cooling process work even better, because as sweat evaporates off your skin it takes a lot of heat with it. You need to worry when you feel to stop sweat while sweating excessively.
