Association Between Implementation of the Athlete Biological Passport and Female Elite Runners’ Performance

2020

The purpose of this research was to evaluate the performances of female middle- and long-distance runners before and after the implementation of a new antidoping strategy (the Athlete Biological Passport [ABP]) in a country accused of systematic doping. A retrospective analysis of the results of Russian National Championships from 2008 to 2017 was performed. The 8 best female performances for the 800-m, 1500-m, 3000-m steeplechase, 5000-m, and 10,000-m events from the semifinals and finals were analyzed. The yearly number of athletes fulfilling standard qualifications for international competitions was also evaluated. Overall, numbers of athletes banned for doping in 2008–2017 were calculat…

The Agr communication system provides a benefit to the populations of Listeria monocytogenes in soil

2014

International audience; In this study, we investigated whether the Agr communication system of the pathogenic bacterium Listeria monocytogenes was involved in adaptation and competitiveness in soil. Alteration of the ability to communicate, either by deletion of the gene coding the response regulator AgrA (response-negative mutant) or the signal pro-peptide AgrD (signal-negative mutant), did not affect population dynamics in soil that had been sterilized but survival was altered in biotic soil suggesting that the Agr system of L. monocytogenes was involved to face the complex soil biotic environment. This was confirmed by a set of co-incubation experiments. The fitness of the response-negat…

High versus low motivating music on intermittent fitness and agility in young well-trained basketball players

2021

The present study aimed to analyse the influence of the music level of motivation, compared to the absence of music, on intermittent fitness and agility, in a group of young well-trained basketball players. On alternate days, thirteen players (14.85 ± 0.68 years, 188 ± 0.05 cm, 75.89 ± 8.02 kg) were assessed of the V-Cut test (agility test including changes of direction) and the 30–15 Intermittent Fitness Test (30-15IFT; maximal running speed under fatigue). There were six testing sessions over three consecutive weeks, with three different randomized conditions: team-selected High Motivating Music (HMM), Low Motivating Music (LMM), and the No-Music condition (NM). Arterial oxygen saturation…

Krytyka wybranych aspektów chrystologii świadków Jehowy w świetle książki Josepfa Ratzingera: Jezus z Nazaretu, cz. I: Od chrztu w Jordanie do Przemi…

2018

Pytanie Chrystusa zawarte we wszystkich ewangeliach synoptycznych: za kogo uważają Go ludzie i kim On jest dla apostołów, wydaje się być wciąż aktualne. Papież Benedykt XVI określa je jako „kamień milowy na drodze Jezusa”. Mimo rozwoju nauk humanistycznych, odpowiedzi jest wiele, a często są one sprzeczne. Niniejsza praca stanowi próbę krytyki wybranych elementów chrystologii świadków Jehowy w świetle obrazu Chrystusa ujętego w książce Josepha Ratzingera Jezus z Nazaretu, cz. I: Od chrztu w Jordanie do Przemienienia. Powyższe zestawienie wykazało, jak liczne i poważne są rozbieżności w postrzeganiu Jezusa przez organizację oraz Jego przedstawieniu w Biblii. Fakty te przemawiają za konieczno…

2021

Background Digital development has caused rehabilitation services and rehabilitees to become increasingly interested in using technology as a part of rehabilitation. This study was based on a previously published study that categorized 4 groups of patients with cardiac disease based on different experiences and attitudes toward technology (e-usage groups): feeling outsider, being uninterested, reflecting benefit, and enthusiastic using. Objective This study identifies differences in the biopsychosocial profiles of patients with cardiac disease in e-usage groups and deepen the understanding of these profiles in cardiac rehabilitation. Methods Focus group interviews and measurements were con…

Entanglement dynamics in superconducting qubits affected by local bistable impurities

2012

We study the entanglement dynamics for two independent superconducting qubits each affected by a bistable impurity generating random telegraph noise (RTN) at pure dephasing. The relevant parameter is the ratio $g$ between qubit-RTN coupling strength and RTN switching rate, that captures the physics of the crossover between Markovian and non-Markovian features of the dynamics. For identical qubit-RTN subsystems, a threshold value $g_\mathrm{th}$ of the crossover parameter separates exponential decay and onset of revivals; different qualitative behaviors also show up by changing the initial conditions of the RTN. We moreover show that, for different qubit-RTN subsystems, when both qubits are …

Glucose regulation and physical performance among older people: the Helsinki Birth Cohort Study

2018

Aims To assess whether disturbances in glucose regulation are associated with impairment in physical performance during a 10-year follow-up. Methods 475 Men and 603 women from the Helsinki Birth Cohort Study were studied. Glucose regulation was evaluated with a 2-h 75-g oral glucose tolerance test (OGTT) in 2001-2004. Subjects were categorised as having either impaired fasting glucose (IFG), impaired glucose tolerance (IGT), newly diagnosed diabetes or previously known diabetes. Physical performance was assessed approximately 10 years later using the validated senior fitness test (SFT). The relationship between glucose regulation and the overall SFT score was estimated using multiple linear…

Glucose regulation and grip strength in adults: Findings from the Helsinki Birth Cohort Study.

2021

Aim: this study aimed to assess the association between grip strength and glucose regulation in a cross-sectional setting.Methods: using data from the Helsinki Birth Cohort Study, 924 men and 953 women were studied at a mean age of 61.6 years. Grip strength was assessed in the dominant hand using a Newtest Grip Force dynamometer. A standard 2-h 75 g oral glucose tolerance test (OGTT) was used to define glucose regulation. The participants were classified into four groups: normoglycaemia, prediabetes (impaired fasting glucose or impaired glucose tolerance), newly diagnosed diabetes and previously known diabetes. The association between grip strength and glucose regulation was assessed using …

Lipid metabolism during exercise

1980

Seven physically fit (well-trained, maximal oxygen uptake 69.6 +/- 4.4 ml x kg-1 min-1) and eight less fit (moderately trained, maximal oxygen uptake 56.1 +/- 5.7 ml x kg-1 x min-1) healthy male subjects were exercised for 4 h by bicycle ergometry against a pedalling resistance calculated to cause oxygen consumption corresponding to approximately 30% of each individual's maximal oxygen uptake value. Respiratory exchange ratio was estimated at 1 h and blood glucose and lactate concentrations and muscle glycogen content at 2 h intervals. Muscle glycogen content decreased markedly during the first 2 h of exercise in the well-trained group but was similar after 4 h exercise in both groups. No m…

Associations of cardiometabolic risk factors with heart rate variability in 6‐ to 8‐year‐old children: The PANIC Study

2019

BACKGROUND Associations of cardiometabolic risk factors with heart rate variability (HRV) in children are unclear. We examined associations of cardiometabolic risk score (CRS) and individual cardiometabolic risk factors with HRV variables in 6- to 8-year-olds. METHODS The participants were a population-based sample of 443 children participating in baseline measurements of the Physical Activity and Nutrition in Children trial. Cardiometabolic risk factors included waist circumference (WC), insulin, glucose, triglycerides, HDL cholesterol, systolic blood pressure (SBP), and diastolic blood pressure (DBP). CRS was calculated as WC + insulin + glucose + triglycerides - HDL cholesterol + the mea…
