Effects of a trail running competition on muscular performance and efficiency in well-trained young and master athletes
2010
International audience; To determine the acute effects of a trail running competition and the age-dependent differences between young and master athletes, 23 subjects [10 young (30.5 ± 7 years), 13 master (45.9 ± 5.9 years)] participated in a 55-km trail running competition. The study was conceived as an intervention study compromising pre, post 1, 24, 48 and 72 h measurements. Measurements consisted of blood tests, ergometer cycling and maximal isometric voluntary contractions (MVC). Parameters monitored included MVC, twitch-and M-wave properties, EMG (RMS) of the vastus lateralis, two locomotion efficiency calculations and muscle damage markers in the blood (CK, LDH). Results indicate pos…
Effects of achievement goals on perceptions of competence in conditions of unfavourable social comparisons: The mastery goal advantage effect
2017
Background Previous prospective studies have documented that mastery-approach goals are adaptive because they facilitate less negative psychological responses to unfavourable social comparisons than performance-approach goals. Aims This study aimed to confirm this so-called ‘mastery goal advantage’ effect experimentally. Methods A 2 × 3 design was adopted where achievement goals (mastery vs. performance) and normative information (favourable vs. no-normative information vs. unfavourable) were manipulated as between participant factors. Sample Participants were 201 undergraduates, 57 males and 144 females, ranging in age from 17 to 55 years (Mage = 22.53, SD = 6.51). Results Regression analy…
Clock genes beyond the clock: CLOCK genotype biases neural correlates of moral valence decision in depressed patients
2007
Gene polymorphisms in the mammalian biological clock system influence individual rhythms. A single nucleotide polymorphism (SNP) in the 3' flanking region of CLOCK (3111 T/C; rs1801260) influenced diurnal preference in healthy humans and caused sleep phase delay and insomnia in patients affected by bipolar disorder. Genes of the biological clock are expressed in many brain structures other than in the 'master clock' suprachiasmatic nuclei. These areas, such as cingulate cortex, are involved in the control of many human behaviors. Clock genes could then bias 'nonclock' functions such as information processing and decision making. Thirty inpatients affected by a major depressive episode under…
Similar relative decline in aerobic and anaerobic power with age with in elite endurance and power master athletes of both sexes
2019
Lower physical activity levels in old age are thought to contribute to the age-related decline in peak aerobic and anaerobic power. Master athletes maintain high levels of physical activity with advancing age and endurance or power training may influence the extent to which these physical functions decline with advancing age. To investigate, 37-90-year-old power (n=20, 45% female) and endurance (n=19, 58% female) master athletes were recruited. Maximal aerobic power was assessed when cycling two-legged (VO2 Peak2-leg ) and cycling one-legged (VO2 Peak1-leg ), while peak jumping (anaerobic) power was assessed by a countermovement jump. Men and women had a similar VO2 Peak2-leg (mL·kg-1 ·min-…
Relation between muscle mass, motor units and type of training in master athletes.
2014
OBJECTIVE: The aim of this study was to measure the number of motor units and muscle mass in power-trained and endurance-trained master athletes compared with community-dwelling older adults. METHODS: Seventy-five master athletes (52 power- and 23 endurance-trained athletes) were recruited at the 2012 European Veteran Athletics Championships in Zittau (Germany). One hundred and forty-nine community-dwelling older adults served as controls. In all participants, the motor unit number index (MUNIX) in the hypothenar muscle and whole body muscle mass was determined by bioelectrical impedance analysis (BIA). RESULTS: In both male and female master athletes, there were significant negative correl…
IL CANTIERE DEL COMPLESSO CARMELITANO DELL’ANNUNZIATA A TRAPANI NELLA SECONDA METÀ DEL CINQUECENTO
2016
Il complesso carmelitano dell’Annunziata a Trapani, costituito dalla chiesa e dal convento annesso (oggi sede del Museo Regionale Agostino Pepoli), appare come un’architettura fortemente stratificata, frutto di una lunga e complessa vicenda progettuale che si snoda dal XIV secolo fino alla metà del Settecento. Il presente studio intende contribuire alla conoscenza del cantiere dell’Annunziata nella seconda metà del Cinquecento, un periodo ancora poco indagato dalle ricerche finora condotte sulla fabbrica, offrendo in particolare alcune riflessioni sui maestri impegnati nella costruzione del complesso architettonico, a partire dall’esame della documentazione relativa alla gestione amministra…
Does unsaponifiable fraction of grape seed oil attenuate nitric oxide production, oxidant and cytotoxicity activities.
2019
Triterpenoids, tocopherols, and phytosterols presented in unsaponifiable fraction of grape seed oil have several beneficial effects comprising antioxidant, anti-inflammatory, and antitumor capacities. In this study, the unsaponifiable fraction of three Tunisian grape seed varieties (Vitis vinifera L.), namely Merlot, Carignan, and Syrah, was investigated. The identified compounds were two triterpenic compounds (β-amyrin, lanosterol), six phytosterols (campesterol, ∆7 -avenasterol, stigmasterol, β-sitosterol, β-sitostanol, cholesterol), and three tocopherols (α, β, and γ tocopherols). The unsaponifiable fraction had significant protection against oxidative damage by modulating NO production …
Principalis fabricator huius felicis urbis Panormi, in S. Montana, F. Scaduto, Antonio Belguardo a master of the late Gothic in Western Sicily and so…
2016
Le informazioni documentarie emerse in questi ultimi anni sulla figura professionale di Antonio Belguardo permettono di ricostruire una biografia attendibile e abbastanza completa di uno dei più importanti e dotati maestri dell’ultimo gotico in Sicilia occidentale e a Palermo, operante tra l’ultimo ventennio del Quattrocento e il primo Cinquecento. Il prestigio e il ruolo del maestro appaiono subito evidenti se si considerano l’intensa attività svolta, il successo presso una committenza “alta” e la rapida ascesa professionale e sociale comprovata dalla carica di capomastro regio (1536) e dalla carriera ecclesiastica del figlio Giovanni probabilmente identificabile con il vescovo di Telese, …
Biological activities of Schottenol and Spinasterol, two natural phytosterols present in argan oil and in cactus pear seed oil, on murine miroglial B…
2014
International audience; The objective of this study was to evaluate the biological activities of the major phytosterols present in argan oil (AO) and in cactus seed oil (CSO) in BV2 microglial cells. Accordingly, we first determined the sterol composition of AO and CSO, showing the presence of Schottenol and Spinasterol as major sterols in AO. While in CSO, in addition to these two sterols, we found mainly another sterol, the Sitosterol. The chemical synthesis of Schottenol and Spinasterol was performed. Our results showed that these two phytosterols, as well as sterol extracts from AO or CSO, are not toxic to microglial BV2 cells. However, treatments by these phytosterols impact the mitoch…
Nucleation in physical and nonphysical systems
2003
Abstract The aggregation of particles out of an initially homogeneous situation is well known in physics. Depending on the system under consideration and its control parameters, the cluster formation in a supersaturated (metastable or unstable) situation has been observed in nucleation physics as well as in other branches. We investigate the well-known example of condensation (formation of liquid droplets) in an undercooled vapour to conclude that the formation of bound states as a phase transition is related to transportation science. We present a comparison of nucleation in an isothermal–isochoric container with traffic congestion on a circular one-lane freeway. The analysis is based, in …
