Blood lactate concentration and delayed muscle soreness: A strategy of practical class for the teaching the integrated metabolic events
Abstract
Our study aimed to identify the mechanisms of action/removal of lactate in a state of exhaustive exercise and to monitor the damage onset muscle soreness (DOMS) progresses due to the fatigue installed. Computerized exercises on a treadmill and cycle ergometer were conducted during a class of Biochemistry of Exercise, with analysis of blood lactate at various times after exercise.For evaluation of DOMS, we useda scale of subjective perception.There was a significant increase (p<0.001) inlactate concentration immediately after exercisefor both exercise models, with a returnclose tonormal levels within1 hour after exhaustion.The manifestation of pain peaked between 24-72 hours after exercise, which led students to under stand that there are distinct metabolic strategies of recovery after exhaustive exercise performance
