About this study

Official title: REBIRTH Active School 2.0. Impact of a School-based Physical Activity Program on the Long-term Improvement of Student Health.

Rebirth active SCHOOL 2.0 is a physical activity intervention program and about to be realised at 40 primary schools in Lower Saxony Germany.

Half of all schools will be assigned to the intervention program or to wait for one year before starting with the movement program. After one and two years, the follow up will take place. After completing baseline examinations (i.e. physical and cognitive functions, physical activity questionnaires) the intervention program will start for one year.

The intervention program is going to be designed with the goal of implementing physical activity of 60 minutes per day. For the main module of movement impulses, the pupils will perform a 5-minute exercise in every lesson, realised by the teachers.

What is being measured

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

  1. Change in Endurance capacity via Six-Minutes Running test

    Completed meters in Six-Minutes running test: German Motor Test 6-18 (Bös, 2009):

    Measured: At baseline, after 1 and 2 years.

  2. Change in Sprint velocity via 20 meter sprint

    20 meter sprint test measured in seconds: German Motor Test 6-18 (Bös, 2009). Scoring the best attempt out of two.

    Measured: At baseline, after 1 and 2 years.

  3. Change in Strength tests via 40 seconds of Push ups and sit ups

    Number of repetitions in 40 seconds of Push ups and sit ups: German Motor Test 6-18 (Bös, 2009)

    Measured: At baseline, after 1 and 2 years.

  4. Change in Coordination exercise: via 60 seconds Single leg stand

    Ground contacts in 60 seconds Single leg stand: German Motor Test 6-18 (Bös, 2009)

    Measured: At baseline, after 1 and 2 years.

Secondary outcomes (48)
  1. Peripheral blood pressure

    Peripheral blood pressure will be measured in a seated position after a resting period of 5 minutes. We will use the oscillometric Dinamap device (Dinamap v150; Fa. GE Medical Systems, Chicago, Illinois, USA). Three measurements will be taken on the right and on the left arm. Between each measurement will be a 1 minute resting period. The Median of the left and the right arm is used for further calculations. If the Median is above the 90th percentile three measurements will be taken again by the investigator using the auscultatory method.

    Measured: At baseline, after 1 and 2 years.

  2. Central blood pressure

    Central blood pressure will be measured in a spinal position using an oscillometric device, the Mobil-O-Graph (I.E.M. GmbH). The cuff size must be chosen accordingly to the arm size. After a resting period of 5 minutes 3 measurements will be taken on the right arm. Between each measurement will be 30 seconds. The mean of the 3 measurements will be used for further calculations.

    Measured: At baseline, after 1 and 2 years.

  3. Arterial pulse wave

    Arterial pulse wave will be measured in a spinal position using the Vicorder. The patient should rest for 5 minutes before the start of the measurement. The thigh cuff will be placed around the patient's upper right thigh as high as possible. The cuff around the neck has to be placed over the right carotid artery. The investigator has to measure from the suprasternal notch vertically to the umbilicus and from the umbilicus diagonally to the mid of the thigh cuff. The length will be added up and the measurement from the suprasternal notch to the cuff around the neck will be subtracted. The length will be used for calculating the arterial pulse wave velocity. Three measurements will be taken with each having 10 consecutive waveforms with similar shape and size. The mean of the 3 measurements will be used for further calculations.

    Measured: At baseline, after 1 and 2 years.

  4. Quality of life via KidKindl

    The quality of life will be assessed applying the KidKindl questionnaire (6 questions, Likert-Skale, 24 Items, Scale 0-100) in a 1 to 1 interview. Higher scores mean a better outcome.

    Measured: At baseline, after 1 and 2 years.

  5. Physical activity questionnaire

    The physical activity will be assessed applying the physical activity questionnaire according to the KIGGS Study (MoMo Modul) in a 1 to 1 interview.

    Measured: At baseline, after 1 and 2 years.

  13. Pediatric Quality of Life

    Quality of Life will be assessed via PedsQL (Quality of Life via PedsQL), 6 Questions in a 1 to 1 interview. Higher scores refect a higher quality of life.

    Measured: At baseline, after 1 and 2 years.

  14. Cognitive function

    Cognitive function (Happiness/Trust/Learning) will be assessed via questionnaire in a 1 to 1 interview (Scale 0-100, a higher score means a better outcome)

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?

This study is still under way. Results are not available in the source record yet.

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?

Change in Endurance capacity via Six-Minutes Running test (time frame: At baseline, after 1 and 2 years.). The study lists 4 primary outcomes in all. 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 11 Mar 2025.
