Cardiopulmonary
Exercise Testing
“Physical exercise requires the interaction of physiological mechanisms
that enable the cardiovascular and respiratory systems to support the increased
energy demands of contracting muscles. Both systems are consequently stressed
during exercise. Their ability to respond adequately to this stress is a
measure of their functional competence or “health”. Exercise testing offers the
investigator the unique opportunity to study simultaneously the cellular,
cardiovascular, and ventilatory systems’ responses under conditions of precisely
controlled metabolic stress”.
Karlman Wasserman in his book „Principles of Exercise Testing and
Interpretation
