Indicate the statement that describes respiratory function in a highly trained athlete at maximal exercise.
A) Unchanged minute ventilation; increased respiratory rate; decreased vital capacity
B) Increased residual volume; increased respiratory rate; decreased alveolar ventilation
C) Increased tidal volume; unchanged minute ventilation; unchanged alveolar ventilation
D) Increased minute ventilation; increased alveolar ventilation; unchanged tidal volume
E) Increased tidal volume; increased minute ventilation; increased alveolar ventilation

Question

Quizplus · Accepted Answer

During maximal exercise, a highly trained athlete experiences increased tidal volume (the amount of air moved in or out of the lungs per breath), increased minute ventilation (the total volume of air inhaled or exhaled per minute), and increased alveolar ventilation (the amount of air reaching the alveoli per minute for gas exchange). These adaptations enhance the body's ability to intake oxygen and expel carbon dioxide, meeting the increased metabolic demands of maximal exercise.
