A quote from the article:
Dena Garner, an assistant professor at the Citadel who has studied athletes using Bite Tech devices since 2005, said she thought some of her original findings were “a fluke.” But “every time I’ve done lactate studies with this mouthpiece, I’m finding there is a difference,” she said.
And a quote from her published paper on the subject (http://bitetech.com/assets/Compendium_Aug09.pdf):
As previous studies had suggested, the difference in lactate levels from pre- to post-exercise was lowered with the mouthpiece vs without the mouthpiece, though not at the level of significance (1.86 mmol/L with mouthpiece vs 2.72 mmol
If there is not a significant difference, then there is not a difference. She should know this.
Beside that, her study only used 10 participants, exercising at "75%–85% of their maximum heart rate", which I can only assume was an age-graded estimate (ie wrong). Any first year kinesiology student should expect there to be a difference in blood lactate levels between 10 people exercising at a heart rate range equivalent to 10 to 12 beats/min.
Sorry, the range is actually more like 20 to 24 beats per minute.
