Architectural and Mechanical Changes after Five Weeks of Intermittent Static Stretch Training on the Medial Gastrocnemius Muscle of Active Adults
27 mars 2023, HE Bruxelles BrabantArticle 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 ... -
The effect of a passive stretch training protocol on performance during a drop jump in humans
30 mars 2013, HE Bruxelles BrabantArticle scientifiqueOur 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, and identify ... -
Full-Face Mask Use during SCUBA Diving Counters Related Oxidative Stress and Endothelial Dysfunction
15 janvier 2022, HE Bruxelles BrabantArticle scientifiqueImpaired flow mediated dilation (FMD), an index of vascular stress, is known after SCUBA diving. This is related to a dysfunction of nitric oxide (NO) availability and a disturbance of the redox status, possibly induced by hyperoxic/hyperbaric gas breathing. SCUBA diving is usually performed with a mask only covering "half face" (HF) and therefore forcing oral breathing. Nasal NO production is ... -
Les effets du crochetage myo-aponévrotique sur l’architecture et les propriétés intrinsèques du muscle gastrocnemius medialis à l’étirement
20 septembre 2018, HE Bruxelles BrabantArticle scientifiqueBackground : this study investigates the effects of the diacutaneous myo-aponeurosis fibrolysis technique, also called hook treatment, on the architectural and mechanical aspects of the muscle. Methods : the overall muscle-tendon unit passive tension and range of motion and muscle architecture of the medial gastrocnemius (fascicle length and pennation angle), as well as mechanical intrinsic ... -
Oxidative Stress Response Kinetics after 60 Minutes at Different (1.4 ATA and 2.5 ATA) Hyperbaric Hyperoxia Exposures
02 août 2023, HE Bruxelles BrabantArticle scientifiqueHyperbaric oxygen therapy (HBOT) is a therapeutical approach based on exposure to pure oxygen in an augmented atmospheric pressure. Although it has been used for years, the exact kinetics of the reactive oxygen species (ROS) between different pressures of hyperbaric oxygen exposure are still not clearly evidenced. In this study, the metabolic responses of hyperbaric hyperoxia exposures for 1 h at ... -
Oxidative Stress Response Kinetics after 60 Minutes at Different Levels (10% or 15%) of Normobaric Hypoxia Exposure
15 juin 2023, HE Bruxelles BrabantArticle scientifiqueIn this study, the metabolic responses of hypoxic breathing for 1 h to inspired fractions of 10% and 15% oxygen were investigated. To this end, 14 healthy nonsmoking subjects (6 females and 8 males, age: 32.2 ± 13.3 years old (mean ± SD), height: 169.1 ± 9.9 cm, and weight: 61.6 ± 16.2 kg) volunteered for the study. Blood samples were taken before, and at 30 min, 2 h, 8 h, 24 h, and 48 h after a 1 ...
