EXERCISE PHYSIOLOGY PRAC EXAM
FLASHCARDS 2026 ACTUAL QUESTIONS
WITH VERIFIED ANSWERS.
Forced expiratory volume in 1 second — volume
What is FEV₁?
exhaled forcefully in the first second.
(Forced Vital Capacity) - Total volume exhaled
What is FVC?
during a full forced expiration.
Whether airflow limitation is obstructive (<70%)
What does the FEV₁/FVC ratio indicate?
or restrictive (normal/high).
Flow rate vs lung volume during forced
What does a flow–volume loop show?
expiration and inspiration.
↓ FEV₁
Normal or ↓ FVC
Key features of obstructive spirometry? ↓ FEV₁/FVC
Scooped-out expiratory curve
Loop shifts left (larger lung volumes)
↓ FEV₁
↓ FVC
Key features of restrictive spirometry? Normal or ↑ FEV₁/FVC
Narrow, tall loop
Loop shifts right (smaller lung volumes)
VE ↑ (tidal volume → breathing
frequency)
How does acute exercise affect spirometry? FEV₁ & FVC unchanged
Loop shifts upward (higher flow)
Bronchodilation ↓ airway resistance
