About this study

Official title: The Intelligent Cardiopulmonary Rehabilitation System: A Feasibility Study in Healthy Subjects

The Intelligent Cardiopulmonary Rehabilitation System (ICRS) was developed to automatically control the resistance of pedaling in combination with the conventional stationary bike by monitoring the user's heart rate for clinical use. To test its feasibility, 8 healthy participants were recruited to complete 12 sessions (3 times per week for 4 weeks) of indoor cycling on the stationary bicycle with ICRS. Subjects were received cardiopulmonary exercise testing (CPET) before and after the biking sessions.The 60-80% of heart rate reserve (HRR) of each participant was determined according to their first CPET results. The algorithm of ICRS was designed to enable the bicycle to adjust its training intensity in accordance with the subject's 60-80% HRR which was detected by wearing a wristband heart rate monitor during cycling. With ICRS, the participants' heart rates during training were expected to fall in the 60-80% HRR, increasing their cardiopulmonary fitness after 12 sessions of indoor cycling.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ICRSDevice

    The ICRS enables a stationary bike to automatically adjust the pedaling resistance (i.e. training intensity) according to the subject's heart rate. The training intensity is determined by monitoring whether the subject is able to maintain a 50-70 cycles/min cadence with 60-80% HRR. Subjects heart rate was detected by a wearable device for heart rate, synching with the stationary bike.

Study groupRoleWhat they receive
Indoor cycling training8 subjects were asked to complete indoor cycling training, 3 times a week for 4 weeks. Each session of training consisted of 30-minute stationary biking (5 minutes of warm-up, 20 minutes of training and 5 minutes of cooldown).
Receives: Device: ICRS

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Peak oxygen consumption (VO2-peak)

    Oxygen consumption (VO2- peak) were measured during our cardiopulmonary test (with a incremental biking and a gas analyzer). The workload was increased at a ramp rate of 5-10 W/min. A cadence at 50~70 rpm was to be maintained.

    Measured: 4 weeks

Secondary outcomes (3)
  1. Peak workload

    The peak workload is measured during a the cardiopulmonary exercise test with a ramped stationary biking.

    Measured: 4 weeks

  2. Compliance of training during the training sessions

    The percentage of time that a subject's heart rate falls in his or her estimated 60-80% HRR over the 12 sessions of training.

    Measured: 4 weeks

  3. Averaged workload during the training sessions

    The averaged workload (watt) that a subject paddled on the stationary bike over the 12 sessions of training.

    Measured: 4 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Cardiac Rehabilitation, run by Taipei Medical University WanFang Hospital at 1 site in Taiwan.

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 3 inclusion and 6 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 4 Aug 2021. 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 Taiwan. 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?

Peak oxygen consumption (VO2-peak) (time frame: 4 weeks). 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 4 Aug 2021.
