start of 1:1-Block public summary

Brief Summary in Lay Language

Bicycle ergometric tests are common procedures in the assesssment of physical capacity in healty persons as well as in patients. Depending on the indication, this test is performed in a recumbend, a semi-recumbent or a seated position. In the context of sports therapy, patients usually train in a seated position.
Aim of this study is to evaluate the influence of seating position on different performance parameters, to interprete and calculate individual perfomances and generate adequate exercise recommendations for different seating positions. For this reason, 20 healthy test persons should be examined using a spiroergometry in three testing conditions (recumbend, a semi-recumbent or a seated position).
In a further implementation (Amendment Nr. 31/13_140100) 20 healthy test persons should be examined to compare three typical stress tests (two incremental tests, one ramp test) and evaluate their influence on different peformance parameters.

Brief Summary in Scientific Language

Bicycle ergometric tests are common procedures in the assesssment of physical capacity in healty persons as well as in patients. Depending on the indication, this test is performed in a recumbend, a semi-recumbent or a seated position. Patients usually are examined in a semi-recumbent position for a good ECG recording. In the context of sports therapy, patients usually train in a seated position.

Aim of this study is to evaluate the influence of seating position on different performance parameter (blood lactate concentration, heart rate, blood pressure, VO2 etc.) to interprete and calculate individual perfomances and generate adequate exercise recommendations for different seating positions. For this reason, 20 healthy test persons should be examined using a spiroergometry in three testing conditions (recumbend, semi-recumbent and seated). Examinations will take place in a random order.
In a further implementation (Amendment Nr. 31/13_140100) 20 healthy test persons should be examined to compare three typical stress tests (two incremental tests, one ramp test) and evaluate their influence on different peformance parameters.
