•Functional laboratory diagnostics following multiple physiologic parameters throughout time
•Typically performed
on bicycle ergometer
•
•Gas analyser, sporttester,
ECG, lactate level analyser
•
•

•Ventilatory: breathing frequency, breath volume, minute ventilation
•
•Circulatory parameters: HR, blood pressure, ECG
•
•(Metabolic parameters: lactate level, pH)
•
•
Spiroergometric parameters

•Ventilatory equivalents: VE /VO2, VE /VCO2
•RQ – respiration quotient (CO2/O2)
•Pulse oxygen
•
•
•
Calculated parameters

BR = breath reserve; VT = ventilatory threshold

•Clinical diagnostics of respiratory or circulatory problems
•Performance of a sportsman
•Anaerobic threshold and VO2max

Bicycle ergometry protocols

•= maximal aerobic capacity
•
•The highest possible minute oxygen consumption at the highest output
•
•Relates to the endurance performance
•
•For interindividual comparison should be relativised (VO2max/kg)
VO2max – maximal oxygen consumption

•The highest levels around 18th year:
– men 46.5 ml/kg/min
– women 37 ml/kg/min
•Decreases with age
•
•Dependency on: ventilation, alveolar-capillary and tissue diffusion, cardiovascular system,
cellular oxidation
VO2max
