    Can I detect lactic acid in sweat as indicative of aerobic threshold in athletes by electrochemical means?

    Many references say sweat contains lactate, not lactic acid.

    However, according to this article

    Artificial sweat is said to is be synthesized "as per standard ISO 3160-2, (20g/l NaCl, 17.5 g/l NH 4 Cl, 5g/l acetic acid and 15 g/l d,l lactic acid with the pH adjusted to 4.7 by NaOH)".

    I thought about detecting the acid with small copper and zinc electrodes on a printed circuit board.
