Physiological Impact of Cloth Mask During Exercise

Not Applicable

• Conditions: Fatigue
• Interventions: Other: Mask

• Registration Number: NCT04887714
• Lead Sponsor: University of Sao Paulo

Brief Summary

Mask wearing during the Covid-19 pandemic has been proven substantially effective in containing the spread of infection, with cloth masks being the most universally used. However, cloth masks may be uncomfortable and have physiological repercussion during exercise. This study aims to investigate the impact of cloth masks during exercise.

Arm && Interventions

Group	Intervention	Description
Mask	Mask	cloth mask wearing

Primary Outcome Measures

Name	Time	Method
perceived exertion ratings	during the intervention	assessed by a scale (7 to 20, with higher values meaning higher perceived exertion)

Secondary Outcome Measures

Name	Time	Method
blood lactate	immediately after the intervention	assessed by lactate analyzer
oxygen consumption	immediately after the intervention	assessed by cardiopulmonary test
spirometry/lung function (OUES)	during the intervention	assessed by cardiopulmonary test
heart rate recovery	immediately after the intervention	assessed by heart rate monitor
Scale of Measuring Subjective Perceptions to maskwearing	immediately after the intervention	assessed by a scale (0 to 10, with higher values meaning more uncomfortable)
spirometry/lung function (VeVCO2 Slope)	during the intervention	assessed by cardiopulmonary test
spirometry/lung function (flow-volume loop)	during the intervention	assessed by cardiopulmonary test
spirometry/lung function (PetCO2)	during the intervention	assessed by cardiopulmonary test
oxygen saturation	immediately after the intervention	assessed by pulse oximetry
vertical jump	immediately after the intervention	assessed by jump test
