Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

High intensity exercise

A dive to 18 meters sea water for a duration of 41 minutes preceded by high intensity cycling

Group Type EXPERIMENTAL

High intensity exercise

Intervention Type OTHER

Subjects performed a repeated Wingate protocol for the exercise condition of the study. This consisted of 4, 30 s maximal efforts on a weight-braked cycle ergometer (Monark 894E, Monark Exercise AB, Sweden) with 4 min active recovery between efforts, preceded by a 5 min warm up. The resistance was set at 7.5% bodyweight for the intervals and 2% for the warm up and active recovery periods.
