SPIROERGOMETRY
PHYSICAL PERFORMANCE DIAGNOSTIC
•Based on the evaluation of physical performance diagnostics, we can give you training or therapy
recommendations or develop a training schedule for you. So, these results are an important
foundation of the improvement of the physical condition and performance, and, thus, your quality of
life.
•
•Spiroergometry is essential for conclusive physical performance diagnostics. During
spiroergometry, you sit on an ergometer wearing a mask breathing through while exercising. The
workload is gradually increased, if possible and medically acceptable, to maximum intensity. At the
same time, your heart function is monitored by using ECG electrodes as well as your blood pressure
by using a blood pressure meter.

SPIROERGOMETRY
PHYSICAL PERFORMANCE DIAGNOSTIC
•The spiroergometry device analyzes the composition of the air you are breathing out. By measuring
certain parameters of this air, we can evaluate the endurance performance, the energy metabolism
during exercise (indirect calorimetry) and the performance of your cardiovascular system. Examining
the condition of heart, lung and cardiovascular system as well as the physical fitness and progress
of training are possible.

Physiology Parameters
•Ventilation parameters : BF, tidal volume (VT), ventilation (VE)….
•
•Exchange of respiratory gases: oxygen uptake (VO2) and output of carbob dioxide (VCO2)
•
•Circulation parameters: HR, BP, ECG
•
•Metabolism: concentration of lactate  (La)

Calculation of other parameters
•Respiratory exchange ratio (RER)
•Ventilatory equivalent (VE/VO2, VE/VCO2)
•Oxygen pulse (VO2/HR)
•

VO2max – max. oxygen uptake
•is the maximum capacity of an individual’s body to transport and use oxygen during incremental
exrecise, which reflects the physical fitness of the individual
•
•is expressed either as an absolutle rate in litres of oxygen per minute (L/min) or as a relative
in mililitres of oxygen per kilogram of bodyweight per minute (mL/kg/min)
•
•The later expression is often used to caomapre the performance of endurance sports athletes.

VENTILATORY ANAEROBIC THRESHOLD
•Ventilatory threshold is as the highest intensity of exercise above which a sustained lactic
acidosis occurs.
•Response of the respiratory systém to an incremental exercise shows primarily a linear increase in
pulmonary ventilation (V), CO2 output (VCO2) and respiratory exchange ratio (RER=VCO2/VO2) with the
intensity of exercise (or level of VO2). At a certain point all the three parameters start to
increase more rapidly than VO2.

VENTILATORY ANAEROBIC THRESHOLD
•The level of anaerobic threshold is one of the indices of aerobic capacity.
•It express the ability of an individual to perform endurance workout, at a higher or lower
percentage of his/hers VO2max and/or maximum power output.
•It also represents, as an intenisty of maximum sustainable steady state, the optimal
individualised stimulus for the development of cardiorespiratory fitness, i.e. for physical
training, especially in endurance sports.
