Overview

The aim of this randomized controlled study is to explore the hypoalgesic response of a 6 minutes of intermittent walking apneas training session at low lung volume in healthy subjects; also, as secondary objectives, to analyze the cardiovascular and respiratory response produced during the intervention.

Interventions

  • Other Walking apnea at Low Lung Volume
    Walking apnea at low 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)
  • Other Walking at normal breathing
    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.

Primary outcome measures

  • Pain pressure threshold (PPT) on thumb, anterior tibial and spinous process of C7 [Time frame: before and after intervention (up 30 minutes)]
Secondary outcome measures (7)
  • Perceived Stress Scale (PSS) [Time frame: before intervention (up 5 minutes)]
  • Pittsburg Sleep Quality Index (PSQI) [Time frame: before intervention (up 5 minutes)]
  • Global Physical Activity Questionnaire (GPAQ) [Time frame: before intervention (up 5 minutes)]
  • Oxygen saturation [Time frame: during intervention (up 6 minutes)]
  • Blood pressure [Time frame: before and after intervention (up 10 minutes)]
  • Rate of perceived exertion (RPE) [Time frame: immediately after intervention (up 10 seconds)]
  • Heart rate [Time frame: during intervention (up 6 minutes)]
