The inside out forehand as a tactical pattern in men’s professional tennis

2017

AbstractThe so-called inside out forehand has an active role in the baseline strategy because it offers the players new possibilities of hitting the incoming ball with their preferred shot by covering their weaker side and, at the same time, playing the ball with more open angles and directions which create more aggressive patterns of play. The purpose of this study is to analyse the use of this shot as well as its incidence on the men’s professional game both, right- and left-handed players. Eighteen matches corresponding to Grand Slam and ATP finals played between 2011 and 2014 were analysed. Eleven players (men) with ATP rankings between 1 and 14 were studied. Data show that the inside o…

Participation and performance trends in ultra-triathlons from 1985 to 2009

2010

We examined the changes in participation and performance trends in ultra-triathlons, from the Double Iron (7.6 km swimming, 360 km cycling, 84.4 km running) to the Deca Iron (38 km swimming, 1800 km cycling, 422 km running), between 1985 (first year of a Double Iron) and 2009 (25 years). The mean finish rate for all distances and races was 75.8%. Women accounted for ∼8-10% of the ultra-triathlons starters. For Double and Triple Iron, the number of finishers per year increased, from 17 to 98 and from 7 to 41, respectively. In the Deca Iron, the finishers per race have remained <20 since the first event was held, up to 2009. Concerning World best performances, the men were ∼19% faster than th…

Le soin dans la technique ou ce que les nouvelles technologies numériques font au soin

2020

Resume Qu’est-ce que le numerique fait au soin ? On presente les dispositifs numeriques comme une reponse aux deserts medicaux, aux inegalites territoriales et comme suppleance eventuelle aux metiers du soin. Mais est-ce seulement possible ? Est-ce que le mode d’investissement de l’espace par le virtuel est articulable sans difficultes a la presence spatiale et corporelle qu’exige le soin ?

A Self-Determined Exploration of Adolescents’ and Parents’ Experiences Derived From a Multidimensional School-Based Physical Activity Intervention

2022

Purpose: Adolescents’ and parents’ experiences within a multidimensional school-based physical activity intervention grounded on self-determination theory were explored. Method: Qualitative data from 29 adolescents (aged 15–17 years) and three parents on behalf of the total students’ families were collected via participant observation (research diary), semistructured interviews, and focus groups. Results: Adolescents perceived that the application of motivational strategies, based on self-determination theory, satisfied their basic psychological needs for autonomy, competence and relatedness, favored self-determined motivation, and gave rise to adaptive consequences (improved physical activ…

Le sommeil de l’adolescent obèse est-il différent de celui de l’adolescent sportif normo-pondéré ?

2018

Introduction L’obesite est associee a une alteration de la quantite et de la qualite du sommeil, en raison notamment d’un syndrome d’apnees obstructives du sommeil (SAOS) tandis que l’exercice physique (EP) ameliore ces parametres. Chez l’adolescent, une relation inverse entre sommeil paradoxal (SP) et exces de poids est aussi rapportee [1] . Les objectifs de cette etude sont de comparer le sommeil de l’adolescent obese (OB, IMC > 30 kg.m−2) a celui de l’adolescent sportif (SPO, EP ≥ 6 h/semaine) par polysomnographie, et d’evaluer l’impact du SAOS sur l’architecture du sommeil de l’OB. Materiel et methodes Trente-deux adolescents (22 OB : 14,9 ans, IMC = 40,2 kg.m−2 ; 12 SP : 15,7 ans, IMC …

Monitorage de la fréquence cardiaque via un brassard à mesure optique pendant une activité quotidienne : étude préliminaire

2018

Introduction La mesure de la depense energetique (DE) en situation ecologique est un enjeu majeur afin d’optimiser le suivi et/ou la prise en charge du patient. La frequence cardiaque (FC) permet de realiser une estimation fidele de cette DE [1] . Cette mesure se realise habituellement a l’aide d’un holter ou d’une ceinture pectorale avec un cardiofrequencemetre. Recemment, des objets connectes permettent de mesurer la FC sur la base de mesures photopletysmographiques sur le membre superieur, simplifiant ainsi la mesure. L’objet de cette etude est de verifier la faisabilite d’un suivi de la FC a l’aide du capteur optique Polar OH1 (Polar Electro Oy, Finlande). Materiels et methodes Pour cet…

2018

Resumen Objetivo El objetivo de este estudio se centrara en la elaboracion de un arbol de decision como una tecnica de analisis de datos que permita establecer combinaciones de factores de riesgo que puedan predisponer a padecer dolor de espalda en esta poblacion. Material y metodos La muestra del estudio estuvo formada por 337 jovenes con una edad de entre 12 y 17 anos de un centro escolar de Castellon. Los sujetos cumplimentaron el Adolescent Sedentary Activity Questionnaire y el cuestionario Nordico de Kuorinka. Ademas, se realizo una valoracion del indice de masa corporal, del porcentaje de grasa corporal, de las caracteristicas de la mochila escolar y del tiempo de transporte de esta y…

Privation de sommeil, syndrome dʼapnées obstructives du sommeil et obésité de lʼadolescent : place des APA dans la prévention et le traitement de ces…

2018

De par la modification du mode de vie, le rythme veille-sommeil est négligé, et le manque de sommeil est devenu aujourdʼhui une préoccupation majeure de santé publique. Chez les jeunes, lʼutilisation inadaptée des écrans le soir et la nuit chez les jeunes est à lʼorigine dʼun retard de phase et dʼune restriction de sommeil. Bien que la relation réciproque entre obésité et privation de sommeil soit déjà reconnue, il est important de comprendre les mécanismes (comportementaux, endocriniens…) conduisant lʼadolescent à une augmentation de la masse corporelle. Par ailleurs, lʼobésité est associée à une modification de lʼarchitecture du sommeil et au développement du syndrome dʼapnées obstructive…
