From a New York Times article on staying fit in the summer heat.
"One reason performance declines on sultry, humid days is that working muscles have to compete with the skin for blood. Directing more blood to the skin removes body heat and helps keep your body's temperature from rising to dangerous levels. But that can mean less blood reaches muscles. At the same time, when your body becomes hotter, muscle enzymes speed up, burning glycogen more rapidly, depleting stores of the sugar that the muscles use for fuel."
