Haemodynamic changes induced by submaximal exercise before a dive and its consequences on bubble formation

Haemodynamic changes induced by submaximal exercise before a dive and its consequences on bubble formation.

OBJECTIVES To evaluate the effects of a submaximal exercise performed 2 h before a simulated dive on bubble formation and to observe the haemodynamic changes and their influence on bubble formation. PARTICIPANTS AND METHODS 16 trained divers were compressed in a hyperbaric chamber to 400 kPa for 30 min and decompressed at a rate of 100 kPa/min with a 9 min stop at 130 kPa (French Navy MN90 pr...

Hemodynamic Changes Induced by Sub-maximal Exercise Prior to a Dive and Its Consequences on Bubble Formation. Authors

Objective: To evaluate the effects of a sub-maximal exercise performed 2 hours before a simulated dive on bubble formation. To observe the hemodynamic changes and their influence on bubble formation. Material and methods: Sixteen trained divers were compressed in a hyperbaric chamber to 400kPa for 30 min and decompressed at a rate of 100 kPa.min with a 9 min stop at 130 kPa (French Navy MN90 pr...

Pre-dive vibration effect on bubble formation after a 30-m dive requiring a decompression stop.

INTRODUCTION The preconditioning of divers to reduce post-dive decompression sickness (DCS) has gained increased interest in diving medical research over the last few years. The beneficial effects of physical exercise, oxygen breathing, hyperbaric exposure, heat exposure, hyperhydration, or nitroglycerin administration before the dive are only a few examples of ongoing research. In this work, w...

Bubble formation and endothelial function before and after 3 months of dive training.

INTRODUCTION It has been suggested that repeated compression-decompression cycles reduce diver susceptibility to decompression sickness (DCS). This study examined whether intensive scuba dive training would reduce bubble formation and modulate endothelial function as shown by skin circulation. METHODS There were 22 military divers who were studied before and after a 90-d program of physical t...
