Le non-renvoi des QPC. Unité ou diversité des pratiques de la Cour de cassation et du Conseil d'État
2018
ISBN : 978-2-37032-164-0; National audience; L'étude du non-renvoi des questions prioritaires de constitutionnalité (QPC) par les Cours suprêmes présente un caractère singulier à bien des égards et notamment car elle touche à l'office du juge ; à son discours et au contrôle des lois par rapport à la norme suprême. Aussi surprenant soit-il, et bien que le mécanisme de la QPC soit effectif depuis le 1er mars 2010, aucune analyse globale n'a été réalisée sur cette problématique, alors même qu'elle permettrait de préciser le contenu des modalités de renvoi qui conditionnent les chances de succès des recours ; de délimiter l'office des Cours suprêmes, et d'observer le cas échéant, son élargissem…
Medial Gastrocnemius Muscle Architecture Is Altered After Exhaustive Stretch-Shortening Cycle Exercise
2019
Muscle architecture is an important component of muscle function, and recent studies have shown changes in muscle architecture with fatigue. The stretch-shortening cycle is a natural way to study human locomotion, but little is known about how muscle architecture is affected by this type of exercise. This study investigated potential changes in medial gastrocnemius (MG) muscle architecture after exhaustive stretch-shortening cycle exercise. Male athletes (n = 10) performed maximal voluntary contractions (MVC) and maximal drop jump (DJ) tests before and after an exercise task consisting of 100 maximal DJs followed by successive rebound jumping to 70% of the initial maximal height. The exerci…
Heart Rate Variability Monitoring During Strength and High-Intensity Interval Training Overload Microcycles
2019
Objective: In two independent study arms, we determine the effects of strength training (ST) and high-intensity interval training (HIIT) overload on cardiac autonomic modulation by measuring heart rate (HR) and vagal heart rate variability (HRV).Methods: In the study, 37 well-trained athletes (ST: 7 female, 12 male; HIIT: 9 female, 9 male) were subjected to orthostatic tests (HR and HRV recordings) each day during a 4-day baseline period, a 6-day overload microcycle, and a 4-day recovery period. Discipline-specific performance was assessed before and 1 and 4 days after training.Results: Following ST overload, supine HR, and vagal HRV (Ln RMSSD) were clearly increased and decreased (small ef…

Saldūdens dūņu mikroorganismu populāciju dinamika jēlglicerīna fermentācijas laikā
2019
Anaerobās fermentācijas ceļā var lietderīgi izmantot jēlglicerīnu, biodīzeļa ražošanas blakusproduktu, iegūstot produktus ar pievienotu vērtību, kas ļauj padarīt biodīzeļa ražošanu ekonomiski izdevīgāku. Šajā darbā tika pētīta mikroorganismu populāciju dinamika jēlglicerīna anaerobās fermentācijas laikā, izmantojot saldūdens dūņas kā inokulātu. Fermentāciju veica 20°C un 37°C temperatūrā 4 un 8 dienas. Noteica izdalītās gāzes tilpumu, kā arī barotņu organisko vielu daudzumu un sastāvu, nosakot ķīmiskā skābekļa patēriņu un veicot šķidruma hromatogrāfiju. Pētīja mikroorganismu populāciju dinamiku, veicot qPCR ar dažādiem baktēriju taksoniem specifiskiem 16S rDNS praimeru pāriem, kā arī veicot…
The Role of the Skeletal Muscle Secretome in Mediating Endurance and Resistance Training Adaptations
2021
Exercise, in the form of endurance or resistance training, leads to specific molecular and cellular adaptions not only in skeletal muscles, but also in many other organs such as the brain, liver, fat or bone. In addition to direct effects of exercise on these organs, the production and release of a plethora of different signaling molecules from skeletal muscle are a centerpiece of systemic plasticity. Most studies have so far focused on the regulation and function of such myokines in acute exercise bouts. In contrast, the secretome of long-term training adaptation remains less well understood, and the contribution of non-myokine factors, including metabolites, enzymes, microRNAs or mitochon…
Sex Differences in the Physiological Network of Healthy Young Subjects
2021
Within human physiology, systemic interactions couple physiological variables to maintain homeostasis. These interactions change according to health status and are modified by factors such as age and sex. For several physiological processes, sex-based distinctions in normal physiology are present and defined in isolation. However, new methodologies are indispensable to analyze system-wide properties and interactions with the objective of exploring differences between sexes. Here we propose a new method to construct complex inferential networks from a normalization using the clinical criteria for health of physiological variables, and the correlations between anthropometric and blood tests b…
Developments in the biomechanics and equipment of Olympic cross-country skiers
2018
Source at: http://doi.org/10.3389/fphys.2018.00976 Here, our aim was to describe the major changes in cross-country (XC) skiing in recent decades, as well as potential future developments. XC skiing has been an Olympic event since the very first Winter Games in Chamonix, France, in 1924. Over the past decades, considerable developments in skiing techniques and improvements in equipment and track preparation have increased skiing speed. In contrast to the numerous investigations on the physiological determinants of successful performance, key biomechanical factors have been less explored. Today’s XC skier must master a wide range of speeds, terrains, and race distances and formats (e.g., dis…
Investigation of the Sympathetic Regulation in Delayed Onset Muscle Soreness: Results of an RCT
2021
Sports-related pain and injury is directly linked to tissue inflammation, thus involving the autonomic nervous system (ANS). In the present experimental study, we disable the sympathetic part of the ANS by applying a stellate ganglion block (SGB) in an experimental model of delayed onset muscle soreness (DOMS) of the biceps muscle. We included 45 healthy participants (female 11, male 34, age 24.16 ± 6.67 years [range 18–53], BMI 23.22 ± 2.09 kg/m2) who were equally randomized to receive either (i) an SGB prior to exercise-induced DOMS (preventive), (ii) sham intervention in addition to DOMS (control/sham), or (iii) SGB after the induction of DOMS (rehabilitative). The aim of the study was t…
