Question 1

During progressive dynamic aerobic exercise, which blood pressure pattern is most characteristic?

Accepted Answer

Systolic pressure rises while diastolic pressure remains stable or decreases slightly

Answer

During dynamic aerobic exercise, increased cardiac output raises systolic BP while peripheral vasodilation in working muscles keeps diastolic BP stable or slightly reduced.

Question 2

Compared to untrained individuals, endurance-trained athletes achieve higher maximal cardiac output primarily due to:

Accepted Answer

Greater stroke volume from cardiac hypertrophy and enhanced ventricular filling

Answer

Endurance training causes eccentric cardiac hypertrophy that increases end-diastolic volume and stroke volume, driving higher maximal cardiac output without requiring a higher maximum heart rate.

Question 3

Exercise-induced bronchospasm (EIB) is most commonly triggered by:

Accepted Answer

Inhalation of cold, dry air during high-intensity exercise

Answer

Cold, dry air inhaled during intense exercise dries and cools airway mucosa, triggering mast cell mediator release and bronchoconstriction characteristic of EIB.

Question 4

In a healthy trained athlete exercising at sea level, arterial oxygen saturation (SpO2) during maximal effort would most likely:

Accepted Answer

Remain above 95% as pulmonary function is rarely the limiting factor

Answer

Healthy athletes at sea level maintain SpO2 above 95% during maximal exercise because pulmonary diffusion capacity and ventilation are adequate to meet oxygen transport demands.

Question 5

The primary mechanism by which aerobic endurance training improves VO2 max is:

Accepted Answer

Increasing stroke volume and therefore maximal cardiac output

Answer

Aerobic training raises stroke volume through cardiac eccentric hypertrophy and plasma volume expansion, increasing maximal cardiac output and oxygen delivery to muscles.
