About this study

Official title: Constant-load Versus Graded Aerobic Exercise for Promoting Cardiorespiratory Fitness and Functional Capacity in Obese Children With Bronchial Asthma: a Randomized Comparative Effectiveness Inquiry

This study aimed to compare the effect of constant-load aerobic exercise (CL-AE) and graded aerobic exercise (G-AE) on cardiopulmonary fitness, and functional capacity in a cohort of obese children with bronchial asthma (BA).

A total of 78 children with BA were randomly assigned to the CL-AE group (n = 26, who underwent moderate-intensity aerobic training with the training load maintained at the same level throughout the entire program, besides the respiratory re-training program), the G-AE group (n = 26, received an intensity- and duration-graded aerobic training in addition to the respiratory re-training program), or the control group (n = 29, who only engaged in a respiratory re-training program). Interventions were administered three times/week for 12 successive weeks.

The cardiopulmonary fitness and functional capacity were evaluated in the three groups before and after the completion of the assigned interventions.

Read the detailed description

Seventy-eight children with BA were recruited from the Pulmonary Medicine/Critical Care and Allergy-Immunology at King Khalid Hospital and two referral hospitals in Riyadh, Saudi Arabia. The study included children with moderate, clinically stable BA, aged 8-18 years, had a body mass index between 30 to 35 kg/m2, had no abnormalities of the lower limbs or spine, maintained constant medication dosages in the past three months, and did not engage in a regular exercise program (in the past six months). Children were excluded if they had exacerbated asthma symptoms, chronic lung comorbidities, and cardiovascular or musculoskeletal conditions expected to hinder the training.

Outcome measures

Cardiopulmonary fitness: The peak oxygen uptake was assessed through the McMaster cycling protocol.

Functional Capacity: The 6-minute walk test was used to assess the submaximal functional capacity Perceived dyspnea and fatigue: Borg's category ratio scale (CR-10) was used to explore how much dyspnea and fatigue they perceived after the 6-minute walk test.

Interventions

The CL-AE group received a 12-week aerobic training, three times in addition to the respiratory re-training. the program included a moderate-intensity aerobic training program, with an intensity set at 65% of the maximum age-predicted heart rate for 45 minutes. The training intensity and duration were maintained at the same level throughout the program. The CL-AE program included a warm-up for 5 minutes and a cool-down for 5 minutes.

The G-AE group received a 12-week aerobic training, three times in addition to the respiratory re-training. The G-AE program commenced with a training intensity corresponding to 50% of the maximum age-predicted heart rate for 25 minutes in the first two weeks, which progressed on a two-week basis, and ended up with a training intensity corresponding to 75% of the maximum age-predicted heart rate for 50 minutes in the last two weeks. The G-AE program also included a warm-up for 5 minutes and a cool-down for 5 minutes.

The control group received the respiratory re-training only, 30 minutes per session, three times a week for 12 consecutive weeks. The program consisted of diaphragmatic breathing exercises, breath-hold, and breathing control exercises, pursed lip breathing, respiratory muscle strengthening, postural correction exercises, and relaxation techniques.

What participants receive

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

  • Constant-load Aerobic ExerciseOther

    The CL-AE group received a 12-week aerobic training, three times in addition to the respiratory re-training. the program included a moderate-intensity aerobic training program, with an intensity set at 65% of the maximum age-predicted heart rate for 45 minutes. The training intensity and duration were maintained at the same level throughout the program. The CL-AE program included a warm-up for 5 minutes and a cool-down for 5 minutes

  • Graded Aerobic exerciseOther

    The G-AE group received a 12-week intensity- and duration-graded aerobic training, three times in addition to the respiratory re-training. The G-AE program commenced with a training intensity corresponding to 50% of the maximum age-predicted heart rate for 25 minutes in the first two weeks, which progressed on a two-week basis, and ended up with a training intensity corresponding to 75% of the maximum age-predicted heart rate for 50 minutes in the last two weeks. The G-AE program also included a warm-up for 5 minutes and a cool-down for 5 minutes.

  • Respiratory Re-trainingOther

    The respiratory re-training lasted for 30 minutes per session and was repeated three times a week for 12 consecutive weeks. The program consisted of diaphragmatic breathing exercises, breath-hold, and breathing control exercises, pursed lip breathing, respiratory muscle strengthening, postural correction exercises, and relaxation techniques.

What is being measured

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

  1. Peak oxygen uptake

    The peak oxygen uptake (mL/kg/min) was assessed through a symptom-free exercise tolerance test (i.e., the McMaster cycling protocol).

    Measured: 3 months

Secondary outcomes (3)
  1. Six-minute walk test

    This test identified the maximum distance (m) that each child was able to cover over six minutes on a straight flat 30-m walkway, without running or jogging. Walking is regarded as more efficient in line with a longer distance coverage.

    Measured: 3 months

  2. Dyspnea

    Dyspnea perception was assessed using Borg's category ratio scale (CR-10). Children rated the level of difficulty they experienced in breathing after completing the six-minute walk test on a 12-point scale. The scale ranges from 0 "no breathing difficulty" to 10 "maximal breathing difficulty".

    Measured: 3 months

  3. Fatigue

    Fatigue perception was evaluated using Borg's category ratio scale (CR-10). Children rated the level of exertion they felt after completing the six-minute walk test on a 12-point scale. The scale ranges from 0 "no fatigue" to 10 "significant fatigue".

    Measured: 3 months

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 8 inclusion and 3 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 22 Mar 2024. 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 Saudi Arabia. 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 uptake (time frame: 3 months). 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 22 Mar 2024.
