Effects of Walking Apnea At High Lung Volume on Hypoalgesia
A study testing Walking apnea at High Lung Volume and Walking normal breathing in people with Pain and Hypoxemia, run by Universidad Rey Juan Carlos at 1 site in Spain.
Trial summary
The aim of this randomized controlled study is to explore the hypoalgesic response of a 6 minutes of intermittent walking apneas training session at high lung volume in healthy subjects; also, as secondary objectives, to analyze the cardiovascular and respiratory response produced during the intervention.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Walking apnea at High Lung VolumeOther
Walking apnea at High Lung Volume Participants walk at 6 km/h (10% slope) on treadmill for 6 minutes. Participants in the experimental group will perform intermittent apneas at high lung volume with a density of 5 seconds, followed by a normal breath of 5 seconds until completing the 6 minutes)
Walking normal breathingOther
Participants walk at 6 km/h (10% slope) on treadmill for 6 minutes. Participants in the control group will remain breathing normally for these 6 minutes.
| Study group | Role | What they receive |
|---|---|---|
| Walking apnea | Experimental | Walking apnea at High Lung Volume Participants walk at 6 km/h (10% slope) on treadmill for 6 minutes. Receives: Other: Walking apnea at High Lung Volume |
| Walking normal breathing | Active comparator | Participants walk at 6 km/h (10% slope) on treadmill for 6 minutes. Receives: Other: Walking normal breathing |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pain pressure threshold (PPT) on thumb, anterior tibial and spinous process of C7
PPT is tested on the dorsal base of the distal phalanx of the thumb on the dominant side and on the muscle belly of the tibialis anterior on the dominant side. The region to be pressed is marked with a pen. The patient is instructed to report with the first appearance of the sensation of "discomfort". An ascending ramp of 0.5 kg/cm/s is applied, at the rhythm of a metronome. The measurement is started on the thumb, and alternated with tibia and C7 until 3 measurements of each region are obtained, enough time to give 30 seconds of rest between measurements in the same region. This protocol has demonstrated high inter observer reliability measuring healthy subjects (ICC = 0.91).
Measured: before and after intervention (up 30 minutes)
Secondary outcomes (6)
Perceived Stress Scale (PSS)
14-item questionnaire about their thoughts and feelings in the last month. The scale has a range of scores from 0 to 56. The lower the score, the more favorable for the patient's health.
Measured: before intervention (up 5 minutes)
Pittsburg Sleep Quality Index (PSQI)
9-item questionnaire on sleep quality in the past month. The scale has a range of scores from 0 to 21. The lower the score, the more favorable for the patient's health.
Measured: before intervention (up 5 minutes)
Global Physical Activity Questionnaire (GPAQ)
6-item questionnaire on the level of physical activity at work, for commuting and in leisure time. A higher score means higher weekly physical activity
Measured: before intervention (up 5 minutes)
Heart rate
Heart rate will be measured during the procedure by finger pulse oximetry.
Measured: during intervention (up 6 minutes)
Oxygen saturation
Oxygen saturation will be measured during the procedure by finger pulse oximetry.
Measured: during intervention (up 6 minutes)
Rate of perceived exertion (RPE)
RPE Borg CR-10 is used to measure how hard your body works during physical activity. It runs from 0 - 10, using numbers to rate how much effort an activity takes.
Measured: immediately after intervention (up 10 seconds)]

Primary outcome
