Bicuspid aortic valve and sports: From the echocardiographic evaluation to the eligibility for sports competition

2021

Bicuspid aortic valve (BAV) is the most common congenital heart defect in adults. Although a BAV may remain without clinical consequences for a lifetime, it can deteriorate in aortic valve stenosis and regurgitation and aortic dilatation. Unfortunately, the impact of regular training on patients with BAV and its natural course is not fully understood, although preliminary evidence suggests that the progression of valvular disease occurs primarily in an independent manner from sports practice. The current review aims to report how to perform a comprehensive echocardiographic examination in athletes with BAV and analyze the current literature on the influence of sports practice and how it imp…

A class of shear deformable isotropic elastic plates with parametrically variable warping shapes

2017

A homogeneous shear deformable isotropic elastic plate model is addressed in which the normal transverse fibers are allowed to rotate and to warp in a physically consistent manner specified by a fixed value of a real non-negative warping parameter ω. On letting ω vary continuously (at fixed load and boundary conditions), a continuous family of shear deformable plates Pω is generated, which spans from the Kirchhoff plate at the lower limit ω=0, to the Mindlin plate at the upper limit ω=∞; for ω=2, Pω identifies with the third-order Reddy plate. The boundary-value problem for the generic plate Pω is addressed in the case of quasi-static loads, for which a principle of minimum total potential …

Effects of high intensity resistance aquatic training on body composition and walking speed in women with mild knee osteoarthritis : a 4-month RCT wi…

2017

Objective: To investigate the effects of 4-months intensive aquatic resistance training on body composition and walking speed in post-menopausal women with mild knee osteoarthritis (OA), immediately after intervention and after 12-months follow-up. Additionally, influence of leisure time physical activity (LTPA) will be investigated. Design: This randomised clinical trial assigned eighty-seven volunteer postmenopausal women into two study arms. The intervention group (n = 43) participated in 48 supervised intensive aquatic resistance training sessions over 4-months while the control group (n = 44) maintained normal physical activity. Eighty four participants continued into the 12-months' fo…

Arbitrarily shaped plates analysis via Line Element-Less Method (LEM)

2018

Abstract An innovative procedure is introduced for the analysis of arbitrarily shaped thin plates with various boundary conditions and under generic transverse loading conditions. Framed into Line Element-less Method, a truly meshfree method, this novel approach yields the solution in terms of the deflection function in a straightforward manner, without resorting to any discretization, neither in the domain nor on the boundary. Specifically, expressing the deflection function through a series expansion in terms of harmonic polynomials, it is shown that the proposed method requires only the evaluation of line integrals along the boundary parametric equation. Further, minimization of appropri…

BIOMECHANICAL FACTORS TO BE TAKEN INTO ACCOUNT TO PREVENT INJURIES AND IMPROVE SPORTING PERFORMANCE ON ARTIFICIAL TURF

2009

This article reviews existing knowledge concerning the epidemiology, instruments and regulatory criteria currently used to evaluate artificial turf soccer pitches. Recent years have seen tremendous growth in the use of artificial turf as a playing surface for sports (rugby, soccer, American football…) and the problems traditionally associated with artificial turf and its relationship with a higher percentage of injuries seem to be disappearing. The contribution of biomechanics to the development of new techniques and instruments for analysing the properties and characteristics of grass pitches has contributed towards close collaboration with the regulatory bodies of different sporting organ…

Artes marciales japonesas: prácticas corporales representativas de su identidad cultural

2011

La implantación y difusión de las artes marciales japonesas en Occidente supuso la importación de prácticas socioculturales privadas de las premisas de su contexto de origen. ¿Cómo afrontar estas prácticas que son ajenas a nuestra identidad cultural? Una interpretación estricta exige entenderlas como prácticas corporales con una idiosincrasia cultural, caracterizadas por incorporar una experiencia vivencial en la que el cuerpo ocupa un lugar preeminente. Su enseñanza y aprendizaje se establecen a través de un sistema triangular integrado por una esencia espiritual, una forma técnica y una estructura física (sin-gi-tai), que se inserta en un proceso singular (shu-ha-ri).

Artificial Neural Networks in Sports: New Concepts and Approaches

2001

Artificial neural networks are tools, which - similar to natural neural networks - can learn to recognize and classify patterns, and so can help to optimise context depending acting. These abilitie...

Author response.

2013

In conclusion, it is key for physical therapists to acknowledge that an important subgroup of patients with OA develop hyperexcitability of the central nervous system and that CS plays a crucial role in the pain reported by these patients. Recent studies published in wellrespected journals support our arguments

Factors associated with potential doping behavior in Olympic-sailing: A gender-specific analysis

2019

BACKGROUND: Olympic-sailing is not contaminated with doping, and special efforts are needed to keep this sport free of doping. The aim of this study was to evaluate factors associated with potential doping behavior (PDB) in professional Olympic sailors. METHODS: The sample of participants were professional Olympic Laser class athletes (N.=80, 39 females ; all >18 years). Data were collected through previously validated questionnaires, utilizing sociodemographic-variables, sport- related- factors, and various factors of hesitation against doping (predictors), and PDB (criterion). To calculate the associations between predictors and the criterion, gender- stratified logistic regression models…
