Mental Fatigue Effects on the Produced Perception of Effort and Its Impact on Subsequent Physical Performances.

2022

The purpose of this study was to investigate the relationship between mental fatigue induced by a demanding cognitive task and impaired physical performance in endurance due to a higher perception of effort. A total of 12 healthy adults and volunteers, who had previously practiced endurance activities for 4 to 8 h per week, performed a one-hour cognitive task involving either the process of response inhibition (Stroop task) or not (visualization of a documentary as control task), then 20 min of pedaling on a cycle ergometer at a constant perception of effort while cardio-respiratory and neuromuscular functions were measured. The Stroop task induces subjective feelings of mental fatigue (vig…

THE INVESTMENT POLITICS AND THE DIVERSIFICATION OF FINANCING RESOURCES IN ROMANIA

2011

A priority for Romania is to maintain an high investment rate, higher than the one of the EU member states, because these countries modernized their energetic, transport and public utility infrastructures, they developed their educational and the public health systems, they reduced the technological and informational differences, decades ago. Through the investment politics, Romania will continue to attract foreign investments, whose annual average was remarkable. For the financing of the investments, a diversification of the internal and external resources is necessary. The internal resources are based on the development of the saving instruments: the development of the market for transact…

School-related stress among sixth-grade students : Associations with academic buoyancy and temperament

2019

The present study examined to what extent sixth-grade students' academic buoyancy and temperament contributed to their school-related stress. A total of 845 students rated their school-related stress at the beginning and end of the school year and their academic buoyancy at the beginning of the year. Parents rated students' effortful control and negative affectivity. The results showed that high academic buoyancy, high effortful control, and low negative affectivity at the beginning of the school year were related to lower school-related stress at the end of the school year, after controlling for gender, GPA, and previous level of stress. Effortful control and negative affectivity had no si…

Coronary artery fistulas: symptoms may not correlate to size. An emblematic case and literature review

2015

<p>Coronary artery fistulas are rare anatomic abnormalities of the coronary arteries present in 0.002% of the general population and represent 14% of all anomalies of coronary arteries. Their clinical relevance focuses mainly on the mechanism of "coronary steal phenomenon”, causing myocardial functional ischemia even in the absence of stenosis, hence common symptoms are angina or dyspnea. Small size fistulas are mostly asymptomatic and have excellent prognosis if managed medically with regular follow-up consisting also in echocardiography every 2-5 years. Big-sized and symptomatic fistulas, on the contrary, should undergo invasive closure, either with a transcatheter approach or with …

Island selection on mammalian life-histories: genetic differentiation in offspring size

2008

BACKGROUND: Since Darwin's pioneering work, evolutionary changes in isolated island populations of vertebrates have continued to provide the strongest evidence for the theory of natural selection. Besides macro-evolutionary changes, micro-evolutionary changes and the relative importance of natural selection vs. genetic drift are under intense investigation. Our study focuses on the genetic differentiation in morphological and life-history traits in insular populations of a small mammal the bank vole Myodes glareolus. RESULTS: Our results do not support the earlier findings for larger adult size or lower reproductive effort in insular populations of small mammals. However, the individuals li…

How Relevant Are Risk Perceptions, Effort, and Performance Expectancy in Mobile Banking Adoption?

2018

This article provides a comprehensive overview of the adoption process using evidence from m-banking adoption in Pakistan. A survey design was used and 189 responses were received from across Pakistan and analyzed using Smart PLS application. Findings suggest that research on the effect of risk in the adoption process remains inconclusive. Contrarily, consumers have overcome many fears due to the usefulness, indispensability, high security features, and effort expended in the use of financial services delivered through m-banking. Perceived risk's (PR) direct influence was found to be generally weak. However, PR plays a major role in the pre-adoption process because it's weak and direct inhi…

Hardiness as a moderator variable between the Big-Five Model and work effort

2015

Abstract The aim of the present study is to analyse hardiness as a moderator variable among personality traits, assessed using the Big-Five or Five Factor Model (FFM) and responses in work effort of workers confronted with stress. Using a multi-occupational sample of 403 subjects, statistically significant correlations between the factors of the FFM and work effort were found, as well as between hardiness and effort, as predicted by the theoretical model. Finally, empirical evidence indicates that hardiness performs a moderating role between the factors of FFM and effort displayed, in the sense that hardiness (understood as a quantitative variable) affects the intensity of the relationship …

HEMATOLOGICAL VARIABILITY ANALYSIS AFTER ROAD MARATHON VS ULTRATRAIL. PREDICTIVE FACTORS

2020

The practice of long- and medium-distance races has exponentially increased the number of participants in recent years. They are carried out under extreme conditions that cause both biochemical and anthropometric changes in athletes and, in addition, have serious risks associated, such as dehydration, thermal disorders, or hypoglycemia. Knowledge regarding alterations at hematological level after this type of effort is limited. The objectives of this pre-post analytical descriptive observational study were: to describe and compare hematological values in amateur runners pre and post road marathon and ultratrail races, and to compare the hematological parameters between the groups in the two…

Good decision-making is associated with an adaptive cardiovascular response to social competitive stress.

2018

Competition elicits different psychological and cardiovascular responses depending on a person's skills. Decision-making has been considered a distal factor that influences competition, but there are no studies analyzing this relationship. Our objective was to analyze whether decision-making affects the response to competition. Specifically, we aimed to test whether good performers on a decision-making test, the Iowa Gambling Task (IGT), showed an adaptive cardiovascular response to competition. In all, 116 participants (44 women) performed the IGT and were classified into Good or Poor decision-makers. Subsequently, they were exposed to a stress task in two different conditions: a face-to-f…
