Predicting the 2000‐m Rowing Ergometer Performance from Anthropometric, Maximal Oxygen Uptake and 60‐s Mean Power Variables in National Level Young R…
2020
Abstract Many studies reported various relationships between 2000-m rowing performance and anthropometric as well as metabolic variables, however, little is known about 60-s mean power in elite youth athletes. The aim of this study was to develop different regression models to predict 2000-m rowing indoor performance time (t2000) using anthropometric variables, maximal oxygen uptake (VO2max) and mean power established during a 60-s all-out test (W60) in national elite youth rowers. Fifteen youth male Italian rowers (age: 15.7 ± 2.0 years; body height: 176.0 ± 8.0 cm; body mass: 71.2 ± 10.0 kg) performed an incremental maximal test, a 60-s all-out test and a 2000-m race simulation using a Co…
Influence of a Thiolate Chemical Layer on GaAs (100) Biofunctionalization: An Original Approach Coupling Atomic Force Microscopy and Mass Spectrometr…
2013
International audience; Widely used in microelectronics and optoelectronics; Gallium Arsenide (GaAs) is a III-V crystal with several interesting properties for microsystem and biosensor applications. Among these; its piezoelectric properties and the ability to directly biofunctionalize the bare surface, offer an opportunity to combine a highly sensitive transducer with a specific bio-interface; which are the two essential parts of a biosensor. To optimize the biorecognition part; it is necessary to control protein coverage and the binding affinity of the protein layer on the GaAs surface. In this paper; we investigate the potential of a specific chemical interface composed of thiolate molec…
Self-esteem and intentions mediate perceived fitness with physical activity in Finnish adolescents with long-term illness or disabilities
2014
Background: The International Classification of Functioning, Disability and Health (ICF) is recognised as the common language in disability research. However, personal factors in the ICF are not explicitly coded because of cultural differences that influence physical activity (PA) participation. The ICF suggests using fitness as a personal factor, as well as other psychological assets. Intentions may serve as such psychological assets and studies on the antecedents to intentions which prompts PA behaviours is lacking in adolescent long term illness or disability (LTID) populations. Objective: The purpose of this study was to report how ICF personal factors can influence participation in PA.…
The effect of contextual variables on the attacking style of play in professional soccer
2021
The aim of this paper was to investigate the interactive effects of contextual variables on the attacking style of play in professional soccer. 5849 team possessions from 40 random matches from Spanish La Liga and English Premier League 2017-2018 were analysed by means of multidimensional observation. Multilevel multivariate logistic regressions showed that home teams had higher odds of implementing fast attacks (p<.05) and lower odds of implementing direct attacks (p<.05) than combinative attacks. High-ranked teams presented lower odds of using direct attacks (p<.05) than combinative attacks in comparison with low-ranked teams, while playing against high-ranked opponents decreased the prob…
Gitelman syndrome DD thiazide diuretics abuse
2014
Abstract Introduction. Gitelman syndrome (GS) is a rare inherited disorder. Mutations in SLC12A3 gene that encode tubular Na+Cl-cotransporter (NCCT) cause hypokalemic metabolic alkalosis, salt loss, hypomagnesaemia and hypocalciuria. The symptoms include weakness, vertigo, hypotension, tetany, paresthesia and nausea. Diagnostic criteria are a normal urine concentrating ability, normal glomerular filtration rate (GFR), hypomagnesaemia (<0,65mmol/l), hypokalemia (<3,6mmol/l) and hypocalciuria (<0,1mmol/mmol creatinine). Previously, the diagnosis was made by exclusion. Today, genetic analysis can ensure diagnosis. Thiazide diuretics (TD) abuse with similar abnormalities can make the d…
Judo as a tool for social integration in adolescents at risk of social exclusion: A pilot study
2020
Purpose: Social policies of the advanced countries have begun to incorporate sport to speak on manifestations of social exclusion, as tool to reach out to young people, strengthen their identity or enhance self-esteem vulnerable groups. Judo can be a good tool for the fulfilment of this purpose because has a philosophy and educational practice that contains much of the core competencies of the educational system. The aim of this study is to analyse the incidence of judo practice in changing attitudes, values, norms and capabilities across organizational forms as a means of enhancing socialization in their interventions with young people at risk of social exclusion. Material/Methods: We used…
Sonication-Induced Modification of Carbon Nanotubes: Effect on the Rheological and Thermo-Oxidative Behaviour of Polymer-Based Nanocomposites.
2018
The aim of this work is the investigation of the effect of ultrasound treatment on the structural characteristics of carbon nanotubes (CNTs) and the consequent influence that the shortening induced by sonication exerts on the morphology, rheological behaviour and thermo-oxidative resistance of ultra-high molecular weight polyethylene (UHMWPE)-based nanocomposites. First, CNTs have been subjected to sonication for different time intervals and the performed spectroscopic and morphological analyses reveal that a dramatic decrease of the CNT's original length occurs with increased sonication time. The reduction of the initial length of CNTs strongly affects the nanocomposite rheological behavio…
Social psychological aspects of ACL injury prevention and rehabilitation: An integrated model for behavioral adherence
2017
Managing rehabilitation for ACL injury is dependent on uptake of, and compliance with, medical and safety recommendations. In this paper, we propose a multi-theory model that integrates self-determination theory and the theory of planned behavior to identify the motivational determinants ACL injury prevention and management behaviors and the processes involved. nonPeerReviewed
Technical, tactical and spatial indicators related to goal scoring in European elite soccer
2020
The aim of this study was to describe the technical, tactical and spatial indicators related to goal scoring in elite European soccer, considering the type of defence and the positioning of the opponent. For the analysis, 8 tactical dimensions related to the final actions in 380 sequences that led to goal during the UEFA Champions League were evaluated by observational methodology. 75.9% of the goals were scored from open play and 24.1% were scored from set pieces. Collective actions produced 51.6% of the total goals while individual actions produced 10.5% of goals. Regarding the penultimate action, crosses were more frequent against organized defences, while passes in behind the defence, o…
Inconsistencies in the pozzolanic strength activity index (SAI) for silica fume according to EN and ASTM
2014
Published version of an article in the journal: Materials and Structures. Also available from the publisher at: http://dx.doi.org/10.1617/s11527-014-0457-6 Open Access New supplementary cementitious materials claimed to possess pozzolan properties emerge frequently. This development is driven both by economic and environmental pressures. Properties of new materials are compared with those of materials already well known, such as silica fume. Several test methods are standardized for making such comparisons, regulated by both European (EN) and American (ASTM) standards. Standardization indicates that procedures are secured to make comparisons valid and informative. In this article the sensit…
