Sodium bicarbonate has been ingested by athletes in an attempt to improve performance by
A)increasing blood buffering capacity.
B)decreasing muscle lactate production.
C)stimulating pulmonary ventilation to increase oxygen transport.
D)increasing plasma volume.

Question

Quizplus · Accepted Answer

Sodium bicarbonate can increase blood buffering capacity by neutralizing excess hydrogen ions produced during exercise. This can delay the onset of muscle fatigue and allow for longer periods of high-intensity exercise. It does not directly affect lactate production, pulmonary ventilation, or plasma volume.
