Summary

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.

Detailed 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.

Conditions

• Ventilation
• Exercise

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	resting standard spirometry	The subject (seated, bust straightened) should perform, after a slow and maximum inspiration, a forced and complete exhalation followed by a new inspiration to the total lung capacity.
DIAGNOSTIC_TEST	maximum exercise testing	Incremental exercise on cycle ergometer with 100W start for men (80W for women) for 4 minutes as part of the warm-up. Then, step increment of a 50W power for men (40W for women) lasting 2 minutes each.
