About this study

Official title: Comparison of Pulse Wave and Blood Pressure Parameters Before, During and After Exercise Ergometry in Healthy Male Subjects - a Randomized, Controlled, Single-blind Study

The objective of this randomized, controlled single blind study is to compare pulse wave and blood pressure measurements before, during and after exercise ergometry in healthy male subjects.

Read the detailed description

In a randomized single-blind study design the investigators explore how well blood pressure parameters calculated using a Pulse Transit Time-based method (device: SOMNOtouchTM RESP) match blood pressure parameters measured by a classic upper arm blood pressure cuff (Mobil-O-Graph® PWA) under standardized load conditions (ergometry).

In 30 healthy male subjects (age 18 - 40 years), cardiovascular parameters before, during and after a standardized load on a bicycle ergometer (half-lying position) are recorded with three different devices (Mobil-O-Graph® PWA versus SOMNOtouchTM RESP versus GeTeMed Vitaguard 3100) and compared.

Primary outcome is the difference of the systolic blood pressure values between the devices Mobil-O-Graph® PWA versus SOMNOtouchTM RESP during the three phases.

The Mobil-O-Graph® PWA blood pressure cuff is applied randomized to the arm with the previously determined higher or lower systolic blood pressure mean difference. The subjects are blinded to the results of the measurements during ergometry.

After a pre-rest period of 12 minutes, the subjects are physically strained on the ergometer for 48 minutes (6 minutes loading phase followed by a 2-minute rest phase; 30 watts increase every 8 minutes up to a maximum load of 180 watts), followed by a 12-minute rest period. Measurements are taken every two minutes with the Mobil-O-Graph® PWA; data acquisition with the SOMNOtouchTM RESP and GeTeMed Vitaguard 3100 devices takes place continuously over a total duration of 72 minutes.

  • Ergometry HOther

    After a pre-rest period of 12 minutes, the subjects are physically strained on the ergometer for 48 minutes (6 minutes loading phase followed by a 2-minute rest phase; 30 watts increase every 8 minutes up to a maximum load of 180 watts), followed by a 12-minute rest periodmaximum load of 180 watts), followed by a 15-minute post-rest period.

    Mobil-O-Graph PWA blood pressure cuff is applied to the upper arm with the previously determined higher systolic blood pressure (reference parameter).

Questions about this trial

What is this clinical trial studying?

A study testing Ergometry H and Ergometry L in people with Healthy Male Subjects, run by ARCIM Institute Academic Research in Complementary and Integrative Medicine at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Difference of the systolic blood pressure (time frame: Physiological parameters are measured continuously (SOMNOtouchTM RESP) and every 2 min (Mobil-O-Graph©PWA) for a total duration of 72 min). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Aug 2019.
