Regional University Hospital Center (CHRU)

Status: Completed

Conditions: Ventilation; Exercise

Treatments: Diagnostic Test: maximum exercise testing; Diagnostic Test: resting standard spirometry

Details and patient eligibility

About

The purpose of this study is to investigate the effect of wearing both neoprene suit and life jacket on respiratory capacities at rest and cardiopulmonary capacities during exercise in windsurfers.

Full description

Windsurfers will perform resting spirometry and exercise test on cycle ergometer until exhaustion in two conditions: with or without equipment. The investigators will measure Forced Vital Capacity, FEV1 peak flow at rest and oxygen uptake, carbon dioxide consumption, ventilation at each step of the incremental exercise and at exhaustion.

Enrollment: 34 patients

Sex: All

Ages: 18 to 35 years old

Volunteers: Accepts Healthy Volunteers

• Have already performed a cardiopulmonary exercise test without any electrocardiographic abnormality
• Subject practicing windsurfing (whatever the level of practice (leisure or competition))

Exclusion criteria

• Subjects < 18 years old
• Pregnant woman
• Inability to consent
• Taking any of the following: oral or inhaled Beta 2 short-acting or long-acting mimetics, oral or inhaled corticosteroids, oral anti-leukotrienes.
• Abnormalities in the resting ECG pattern
