As Ergometer for sportsmen as kind of sport-related an equipment as possible (Laufbandergometer, Ruderergometer, swimming channel, Paddelergometer etc.) is used, for patients in the German-speaking countries usually a Fahrradergometer, more rarely also a Laufbandergometer. Usually in the angloamerikanischen countries the exercise treadmill test (ETT) is completed or graded exercise stress test (GXT) on the run volume or standardized climbing stages.

Employment

In the achievement sport and the sport medicine the Ergometrie is used, in order to determine the performance level of a sportsman, the results serves further training planning. Within the medical range it with the recognition and process evaluation of heart and lung illnesses help and are an important aid to the risk and prognosis estimation. The rehablitation medical profession use it, in order to be able to give purposeful Therapiempfehlungen and examine effected measures for their effectiveness.

Execution

Depending upon an investigation goal and rehearsing and many different load minutes are usual. In the medicine a gradual load over nine to twelve minutes either after one of the WHO or one of the federal committee for achievement sport (BAL) suggested pattern is usually accomplished. The WHO recommends a beginning with 25 or 50 Watts and an increase by 25 Watts after in each case two minutes, the BAL an entrance with 50 or 100 Watts and an increase by 50 Watts every three minutes. Those pulse frequency maximally which can be reached is calculated with the formula 220 minus age (in years), a Ausbelastung with reaching the lower standard deviation (Ausbelastungsfrequenz minus approx. 10-12 impacts per minute) is accepted.

Findings

The maximum maximum stress is determined and permitted absolutely in Watts and relative to in per cent age, sex and weight-referred target achievement or target workload with heart-ill patients of conclusions on the life expectancy (prognosis) and the risk of planned operations.

Angina Pectoris and a lowering of the ST-distance in the ELECTROCARDIOGRAM are the typical findings with koronarer heart illness. Main criterion for a abnorme reaction is a horizontal or deszendierende ST-distance-lowering of 0,10 mVs. It is usually expression of an load-induced blood circulation disturbance of the heart muscle. Through already in peace existing electrocardiogram changes and the influence of some medicines (e.g. Beta blockers and Digitalis) the force of expression of the Ergometrie for this question is limited.

Also certain heartbeat disturbances, which begin under load or strengthened arise, can be reference to a blood circulation disturbance.
