This ion will ultimately make the blood suitably acidic that the breakdown of the energy source glucose is reduced, another negative impact on athletic performance. In these conditions, athletes will often criticise of a burning sensation in their working muscles, a condition that is sometimes accompanied by difficulties with muscle coordination or movement. These symptoms may continue after a high intensity event for as long as 48 hours. These physical consequences are attributable to the hydrogen ion and not the lactic acid itself. For this reason, lactic acid is wrongly regarded as a waste product.
