Elevations of Extracellular Vesicles and Inflammatory Biomarkers in Closed Circuit SCUBA Divers
22 mars 2023, Arya, Awadhesh; BALESTRA, Costantino
; Bhopale, Veena; Tominen, Laura; Raisanen-Sokolowski, Anne; Dugrenot, Emmanuel; Thom, Stephen, HE Bruxelles Brabant
Article scientifiqueBlood-borne extracellular vesicles and inflammatory mediators were evaluated in divers using a closed circuit rebreathing apparatus and custom-mixed gases to diminish some diving risks. "Deep" divers (n = 8) dove once to mean (+/-SD) 102.5 +/- 1.2 m of sea water (msw) for 167.3 +/- 11.5 min. "Shallow" divers (n = 6) dove 3 times on day 1, and then repetitively over 7 days to 16.4 +/- 3.7 msw, for ... -

Pulmonary Effects of One Week of Repeated Recreational Closed-Circuit Rebreather Dives in Cold Water
28 décembre 2022, Gouin, Emmanuel; BALESTRA, Costantino; Orsat, Jeremy; Dugrenot, Emmanuel; L'Her, Erwan, HE Bruxelles Brabant
Article scientifiqueBackground and Objectives: The use of closed-circuit rebreathers (CCRs) in recreational diving is gaining interest. However, data regarding its physiological effects are still scarce. Immersion, cold water, hyperoxia, exercise or the equipment itself could challenge the cardiopulmonary system. The purpose of this study was to examine the impact of CCR diving on lung function and autonomous cardiac ... -
Architectural and Mechanical Changes after Five Weeks of Intermittent Static Stretch Training on the Medial Gastrocnemius Muscle of Active Adults
27 mars 2023, Levenez, Morgan; Moeremans, Mathieu; Boorghs, Cédric; Vigouroux, Florent; Leveque, Clément; ; BALESTRA, Costantino, HE Bruxelles Brabant
Article scientifiqueWe investigated the effects of intermittent long-term stretch training (5 weeks) on the architectural and mechanical properties of the muscle-tendon unit (MTU) in healthy humans. MTU's viscoelastic and architectural properties in the human medial gastrocnemius (MG) muscle and the contribution of muscle and tendon structures to the MTU lengthening were analyzed. Ten healthy volunteers participated ... -
Oxygen Variations-Insights into Hypoxia, Hyperoxia and Hyperbaric Hyperoxia - Is the Dose the Clue?
20 septembre 2023, BALESTRA, Costantino; Mrakic-Sposta, Simona; Virgili, Fabio, HE Bruxelles Brabant
Article scientifiqueon, nitrogen and hydrogen); aerobic organisms depend on it to release energy from carbon-based molecules. The concentration of oxygen in the atmosphere is ~20.93–20.95% (209–460 ppm), but this has fluctuated markedly throughout geological history. It stabilized within a habitable range, between ~15% and 35%, which has been maintained from the Cambrian period 540 million years ago until today [1]. The ... -
Heart Rate Variability During a Standard Dive: A Role for Inspired Oxygen Pressure?
13 août 2021, Lafère, Pierre; ; ; ; Germonpré, Faye-Lisa; Marroni, Alessandro; Cialoni, Danilo; Bosco, Gerardo; BALESTRA, Costantino, HE Bruxelles Brabant
Article scientifiqueIntroduction: Heart rate variability (HRV) during underwater diving has been infrequently investigated because of environment limitations and technical challenges. This study aims to analyze HRV changes while diving at variable hyperoxia when using open circuit (OC) air diving apparatus or at constant hyperoxia using a closed-circuit rebreather (CCR). We used HRV analysis in time and frequency domain ... -
Comparison of insulation provided by dry or wetsuits among recreational divers during cold water immersion (< 5 degrees C)
Article scientifiqueBACKGROUND: Divers thermal status influences susceptibility to decompression sickness hence the need for proper insulation during immersion in cold water. However, there is a lack of data on thermal protection provided by diving suits, hence this study. MATERIALS AND METHODS: Two different groups of divers wearing either a wetsuit (n = 15) or a dry suit (n = 15) volunteered for this study. Anthropometric ... -

The "ON-OFF" Switching Response of Reactive Oxygen Species in Acute Normobaric Hypoxia: Preliminary Outcome
16 février 2023, BALESTRA, Costantino; Mrakic-Sposta, Simona; Gussoni, Maristella; Marzorati, Mauro; Porcelli, Simone; Bosco, Gerardo; Montorsi, Michela; Lafortuna, Claudio; Vezzoli, Alessandra, HE Bruxelles Brabant
Article scientifiqueExposure to acute normobaric hypoxia (NH) elicits reactive oxygen species (ROS) accumulation, whose production kinetics and oxidative damage were here investigated. Nine subjects were monitored while breathing an NH mixture (0.125 F(I)O(2) in air, about 4100 m) and during recovery with room air. ROS production was assessed by Electron Paramagnetic Resonance in capillary blood. Total antioxidant ... -
Oxidative Stress Response’s Kinetics after 60 Minutes at Different (30% or 100%) Normobaric Hyperoxia Exposures
30 décembre 2022, Leveque, Clément; Mrakic-Sposta, Simona; Lafère, Pierre; Vezzoli, Alessandra; Germonpré, Peter; Beer, Alexandre; Mievis, Stéphane; Virgili, Fabio; ; ; Guerrero, François; BALESTRA, Costantino, HE Bruxelles Brabant
Article scientifiqueOxygen is a powerful trigger for cellular reactions and is used in many pathologies, including oxidative stress. However, the effects of oxygen over time and at different partial pressures remain poorly understood. In this study, the metabolic responses of normobaric oxygen intake for 1 h to mild (30%) and high (100%) inspired fractions were investigated. Fourteen healthy nonsmoking subjects (7 ... -
