The flexibility itself doesn't reduce power.. the static stretching before a workout does.
Although it might be debatable whether you get a better stretch-shorten cycle from a muscle at the edge of its ROM instead of more flexibility than you need. Well, specifically stretched out muscle spindles may not provide as good of feedback if they are more flexible than they need to be; however, I don't think this makes THAT big of a difference. If we were to consider the foot placement in sprinting, high jump and long jump.. they don't operate at the edge of their ROM when performing these activities and also strongly utilize the stored energy from stretch-shorten cycle to perform at elite levels.
Do you have any data on that Greg?
