The effect of pre-dive ingestion of dark chocolate on endothelial function after a scuba dive
15 mars 2015,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Objective: The aim of the study was to observe the effects of dark chocolate on endothelial function after scuba diving.
Methods: Forty-two male scuba divers were divided into two groups: a control (n=21) and a chocolate group (n=21). They performed a 33-metres deep scuba-air dive for 20 minutes in a diving pool (Nemo 33, Brussels). Water temperature was 33⁰C. The chocolate group ingested 30 g ...
Nitric oxide-related endothelial changes in breath-hold and scuba divers
01 mars 2013,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Objective: Scuba and breath-hold divers are compared to investigate whether endothelial response changes are similar despite different exposure(s) to hyperoxia.
Design: 14 divers (nine scuba and five breath-holding) performed either one scuba dive (25m/25 minutes) or successive breath-hold dives at a depth of 20 meters, adding up to 25 minutes of immersion time in a diving pool. Flow-mediated ...
Dark chocolate reduces endothelial dysfunction after successive breath-hold dives in cool water
16 septembre 2013,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Objective: The aim of this study is to observe the effects of dark chocolate on endothelial function after a series of successive apnea dives in non-thermoneutral water.
Methods: Twenty breath-hold divers were divided into two groups: a control group (8 males and 2 females) and a chocolate group (9 males and 1 female). The control group was asked to perform a series of dives to 20 m adding up to ...
Venous gas emboli are involved in post-dive macro, but not microvascular dysfunction
21 janvier 2017,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Purpose: Previous studies have shown vascular dysfunction of main conductance arteries and microvessels after diving. We aim to evaluate the impact of bubble formation on vascular function and haemostasis. To achieve this, we used a vibration preconditioning to influence bubble levels without changing any other parameters linked to the dive.
Methods: Twentty-six divers were randomly assigned to ...
Pre-dive Whole-Body Vibration Better Reduces Decompression-Induced Vascular Gas Emboli than Oxygenation or a Combination of Both

,
- Article scientifique
Article scientifique
Purpose: Since non-provocative dive profiles are no guarantor of protection against decompression sickness, novel means including pre-dive "preconditioning" interventions, are proposed for its prevention. This study investigated and compared the effect of pre-dive oxygenation, pre-dive whole body vibration or a combination of both on post-dive bubble formation. Methods: Six healthy volunteers performed ...
Decreased Incidence of Pulmonary Barotrauma After Discontinuation of Emergency Free Ascent Training
22 août 2018,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
INTRODUCTION: Because a significant association between training to perform emergency free ascent (EFA) and the occurrence of pulmonary barotrauma (PBT) was demonstrated in 2006, the Belgian Underwater Federation (BUF) decided to discontinue this procedure. An evaluation was needed 10 yr after the implementation of this change. METHODS: All medical records with a diagnosis of PBT that occurred in ...

Early detection of diving-related cognitive impairment of different nitrogen-oxygen gas mixtures
30 juin 2019,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
NTRODUCTION: Cognitive impairment related to inert gas narcosis (IGN) is a threat to diving safety and operations at depth that might be reduced by using enriched air nitrox (EANx) mixtures. Using critical flicker fusion frequency (CFFF), a possible early detection of cognitive abilities/cerebral arousal impairment when breathing different oxygen (O2) fractions was investigated. METHODS: Eight male ...
Field study of anthropomorphic and muscle performance changes among elite skippers following a transoceanic race
12 juin 2020,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
BACKGROUND: Ocean racing has become increasingly demanding, both physically and psychologically. The aim of the study was to assess global changes after a transoceanic race. MATERIALS AND METHODS: Eight male sailors were evaluated pre- and post-race through anthropometric measurements (weight, skinfold, girth at different level and estimated body fat percentage), multifrequency tetrapolar bioelectrical ...
Physiological characteristics associated with increased resistance to decompression sickness in male and female rats
23 juillet 2020,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Decompression sickness (DCS) is a complex and poorly understood systemic disease with wide inter-individual resistance variability. We selectively bred rats with a 3-fold greater resistance to DCS than standard ones. To investigate possible physiological mechanisms underlying the resistance to DCS, including sex-related differences in these mechanisms, 15 males and 15 females resistant to DCS were ...
