Question

Quizplus · Accepted Answer

During maximal exercise lasting between 60 and 180 seconds in the athlete. This is because during high-intensity exercise, the body's demand for energy is greater than the amount of oxygen that can be delivered to the working muscles. This results in an increased reliance on anaerobic metabolism, which produces lactate as a byproduct. Well-trained athletes can sustain high-intensity exercise for longer and have a higher lactate threshold, so they will produce more lactate at maximal effort compared to untrained individuals.
