About this study
Official title: The Acute Effect of High Intensity Interval Exercise on Respiratory Function and Rhinitis Symptoms in Patients With Allergic Rhinitis
The purpose of this study was to determine the acute effect of high intensity interval exercise on respiratory function and rhinitis symptoms in allergic rhinitis patients.
Read the detailed description
Twelve patients with allergic rhinitis aged between 19 and 31 years who had a positive skin prick test to house dust mite (D. pteronyssinus). The experiment was a crossover design in which each participant was given two types of high-intensity interval training exercise (HIT): HIT 1:1 (high intensity for 1 minute at 85-90% of maximum heart rate, then alternating with low intensity 50-55% of maximum heart rate for 1 minute) and HIT 1:2 (high intensity for 1 minute at 85-90% of maximum heart rate, then alternating with low intensity 50-55% of maximum heart rate for 2 minutes). Rhinitis symptoms, nasal blood flow, peak nasal inspiratory flow, pulmonary functions, respiratory muscle strength, and fractional exhaled nitric oxide were measured before and immediately, 15 minutes, 30 minutes, 45 minutes, and 60 minutes after exercise for each exercise program.

What is being measured
The primary outcome is the main question the study is designed to answer.
Rhinitis symptom scores change
Nasal symptoms were assessed using Total Nasal Symptom Score (TNSS) questionnaire. The subjects were asked to score symptoms of persistent allergic rhinitis before and after yoga training protocol. The total nasal symptom scores were computed as the sum of four individual nasal symptom scores; nasal congestion, itching, sneezing, and rhinorrhea. The scores ranged from 0 to 3 scale (0=none, 1=mild, 2=moderate, 3= severe)
Measured: Change after each exercise immediately, 15 minutes, 30 minutes, 45 minutes, and 60 minutes
Peak nasal inspiratory flow change
The subjects placed a mask, which is turned onto a plastic cylinder through which the air passes during inspiration, over the nose and mouth and inspired forcefully through the nose, with lips tightly closed. Inside the cylinder, there is a diaphragm that moves to the airflow, and the maximum peak flow is registered in a scale range from 30-370 L/min. During the procedure, the subjects placed a mask over the nose and mouth and inspired forcefully through the nose, with lips tightly closed.
Measured: Change after each exercise immediately, 15 minutes, 30 minutes, 45 minutes, and 60 minutes
Nasal blood flow change
Laser Doppler flowmetry (DRT4 moor instrument, UK.) was used to measure of the nasal blood flow (NBF). Before the test each subject rested for one hour in a separate room. During the test, they were instructed to breathe normally breathe and not to speak, cough, or move. A lateral endoscopic probe with a flexible nylon sheath 1.34-mm-diameter flexible nylon sheath was placed to the front of the nose. Nasal blood flow measurements were performed before immediately, 15 minutes, 30 minutes, 45 minutes, and 60 minutes after exercise for each exercise program.
Measured: Change after each exercise immediately, 15 minutes, 30 minutes, 45 minutes, and 60 minutes
Pulmonary functions change
The participants were asked to wear a nose clip while sitting on a chair, and the researcher gave the participants the step-by-step protocol to prevent an incorrect maneuver. For the FVC maneuver, three cycles of slow normal breathing were performed before demonstrating forced inspiration and expiration.
Measured: Change after each exercise immediately, 15 minutes, 30 minutes, 45 minutes, and 60 minutes
Respiratory muscle strength change
Respiratory muscle strength was assessed by measuring Maximal Inspiratory Pressure (MIP) and Maximal Expiratory Pressure (MEP) in cmH2O. The participants were in a sitting position using a portable handheld mouth pressure meter (i.e., MicroRPM) with a nose clip. For the MIP measurement, the participants were asked to exhale until they felt no air remaining in their lungs (starting with the functional residual capacity [FRC] point), then held the device on their mouth and inhaled forcefully for 1-2 seconds. For the MEP measurement, the participants were asked to inhale until their lungs were completely filled with air (starting with the total lung capacity [TLC] point), then they kept the device on their mouth and exhaled forcefully for 1-2 seconds
Measured: Change after each exercise immediately, 15 minutes, 30 minutes, 45 minutes, and 60 minutes
Secondary outcomes (1)
Fractional exhaled nitric oxide
Participants inhaled deeply for two to three seconds before exhaling slowly. Normally, it took 10 seconds to exhale.
Measured: Change after each exercise immediately, 15 minutes, 30 minutes, 45 minutes, and 60 minutes

Questions about this trial
What is this clinical trial studying?
A study testing HIT 1:1 and HIT 1:2 in people with Allergic Rhinitis, run by Chulalongkorn University at 1 site in Thailand.
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 7 inclusion and 2 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 2023. 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 Thailand. 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?
Rhinitis symptom scores change (time frame: Change after each exercise immediately, 15 minutes, 30 minutes, 45 minutes, and 60 minutes). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05779046, which also lists 7 linked publications.
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 2023.
