Clinical Trial 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.

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.

Related Conditions & MeSH terms

• Exercise
• Ventilation

Intervention

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.
• 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.
