High Intensity Cycling Before SCUBA Diving Reduces Post-decompression Microparticle Production and Neutrophil Activation

University Hospital of Split

Status: Completed

Conditions: SCUBA Diving; Decompression Sickness

Treatments: Other: High intensity exercise

Study type: Interventional

Funder types: Other

Identifiers

NCT02064361

SCUBACYC

Details and patient eligibility

About

The purpose of this study is to determine the impact of high intensity,anaerobic exercise, in the form of cycling, on SCUBA diving. Outcomes are determined by the quantification and subtype of circulating microparticles, complete blood counts, and the quantification of venous gas emboli, measured via transthoracic echocardiography, in the cardiac cavities.
