The effect of a passive stretch training protocol on performance during a drop jump in humans
15 juin 2013,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Aim: Our study's aim is to show how a five-week stretch training protocol, based on passive stretching, can change muscle performance during a drop jump (stretch shortening cycle).
Methods: This study observes in 8 healthy subjects (four males and four females), the effect of a 5-week passive stretch training protocol on the stretch shortening cycle (SSC) during the performance of a drop jump, ...
Effect of tetrahydrobiopterin and exercise training on endothelium-dependent vasorelaxation in SHR

- Article scientifique
Article scientifique
We examined whether the improvement of impaired NO-dependent vasorelaxation by exercise training could be mediated through a BH4-dependent mechanism. Male spontaneously hypertensive rats (SHR, n = 20) and Wistar-Kyoto rats (WKY, n = 20) were trained (Tr) for 9 weeks on a treadmill and compared to age-matched sedentary animals (Sed). Endothelium-dependent vasorelaxation (EDV) was assessed with ...
A red orange extract modulates the vascular response to a recreational dive: a pilot study on the effect of anthocyanins on the physiological consequences of scuba diving

Article scientifique
Nutritional antioxidants have been proposed as an expedient strategy to counter the potentially deleterious effects of scuba diving on endothelial function, flow-mediated dilation (FMD) and heart function. Sixteen volunteers performing a single standard dive (20 min at 33 m) according to US Navy diving procedures were randomly assigned to two groups: one was administered with two doses of 200 mg of ...

Cet article a pour objectif de décrire un processus de recherche engagé sur la formation pratique d’éducateurs sociaux en Belgique francophone dans le cadre d’une association dénommée Form’Educ. Cela se passe dans un groupe de huit Hautes-Ecoles engagées ensemble dans un projet de recherche pendant cinq ans (2011-2015) dans le but d'échanger leurs pratiques de formation concernant la formation ...
Relationships between plasma lipids, proteins, surface tension and post-dive bubbles

- Article scientifique
Article scientifique
Decompression sickness (DCS) in divers is caused by bubbles of inert gas. When DCS occurs, most bubbles can be found in the venous circulation: venous gas emboli (VGE). Bubbles are thought to be stabilized by low molecular weight surfactant reducing the plasma-air surface tension (γ). Proteins may play a role as well. We studied the interrelations between these substances, γ and VGE, measured before ...

Livre/Ouvrage ou monographie
The editors of and authors of this book are a cadre of scientists and physicians with broad experience and knowledge of diving physiology and decompression theory. As is often the case, it requires a group effort to succeed in advancing practical knowledge. The colloquialism "the whole is greater than the sum of its parts" is often true and the PHYPODE Reasearch Group epitomizes this concept. By ...
Do Environmental Conditions Contribute to Narcosis Onset and Symptom Severity?

- Article scientifique
Article scientifique
Although many factors contributing to inert gas narcosis onset and severity have been put forward, the available evidence is not particularly strong. Using objective criteria, we have assessed brain impairment associated with narcosis under various environmental diving conditions. 40 volunteers performed a no-decompression dive (33 m for 20 min) either in a dry chamber, a pool or open sea. They were ...
Effects of oxygen-enriched air on cognitive performance during SCUBA-diving - an open-water study
12 avril 2017,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Backround: Nitrogen narcosis impairs cognitive function, a fact relevant during SCUBA-diving. Oxygen-enriched air (nitrox) became popular in recreational diving, while evidence of its advantages over air is limited. AIM: Compare effects of nitrox28 and air on two psychometric tests. METHODS: In this prospective, double-blind, open-water study, 108 advanced divers (38 females) were randomized to an ...
Evidence of Heritable Determinants of Decompression Sickness in Rats
22 juillet 2017,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
NTRODUCTION: Decompression sickness (DCS) is a complex and poorly understood systemic disease caused by inadequate desaturation following a decrease of ambient pressure. Strong variability between individuals is observed for DCS occurrence. This raises questions concerning factors that may be involved in the inter-individual variability of DCS occurrence. This study aimed to experimentally assess ...
Dive Risk Factors, Gas Bubble Formation, and Decompression Illness in Recreational SCUBA Diving: Analysis of DAN Europe DSL Data Base

- Article scientifique
Article scientifique
Introduction: The popularity of SCUBA diving is steadily increasing together with the number of dives and correlated diseases per year. The rules that govern correct decompression procedures are considered well known even if the majority of Decompression Sickness (DCS) cases are considered unexpected confirming a bias in the "mathematical ability" to predict DCS by the current algorithms. Furthermore, ...
