Question
Describe the effects of training on the pulmonary system.
Markscheme
a. ventilation rate at rest is reduced;
b. maximum ventilation rate (during exercise) increases;
c. diaphragm and intercostal muscle strength increase;
d. vital capacity may increase/ VO2 max may increase;
Do not accept answers relating to cardiac output.
Examiners report
The effects of training were sometimes not related to the pulmonary system.
