Introduction. — The aim of the study was to verify, in a non-professional handball female, if theintroduction of two short workouts per week during all season has a positive impact on muscularperformance.Methods. — Eighteen female playing handball at the top Belgian level were monitored duringthe complete season. Ten of these girls (‘‘Muscu’’ group) achieved, in addition to their usualtraining, two short (30 minutes) strength training sessions weekly. The other (‘‘Control’’ group)followed the usual training, without any strength training session. A battery of tests (leg power,arm power, vertical jump, sprint, throwing, flexibility) has been set up to four times during theseason to follow up muscular performance.Results. — According to the literature, the ‘‘Control’’ group showed any change in performanceduring the year. By contrast, ‘‘Muscu group results demonstrated that the short strength trai-ning program was efficient, with significant improvements in leg power (P < 0.005) and sprint(P < 0.05) tests. Increase in vertical jump was very close to the level of significance (P = 0.06).Arms power did not improve but appeared to be superior in the ‘‘Muscu’’ group in comparisonwith ‘‘Control’’ at the end of the season, which was not the case at the beginning.© 2013 Elsevier Masson SAS.

Pendant la petite enfance, les grands prématurés restent fragiles. Une étude récente (de Kieviet et al, 2009) met en évidence un retard psychomoteur de cette population par rapport à la normale. A partir de 3 ans, de nombreuses activités existent pour stimuler leur développement moteur mais avant cet âge, rien n’est organisé. Nous avons donc décidé de mettre sur pied une activité de psychomotricité adaptée à cette population, entre 1,5 et 3 ans. L’objectif de cette étude consistait à valider cette activité de développement originale. Appliquant les principes des recherches-action, nous avons structuré notre démarche en quatre phases : (1) la planification durant laquelle nous avons mené une réflexion sur l’organisation et le contenu de l’activité ; (2) l’intervention au cours de laquelle fut expérimentée l’activité et fut collectée une série d’informations ; (3) l’analyse des données et ; (4) l’aménagement d’un nouveau modèle tenant compte des étapes précédentes. La validation menée lors de l’intervention repose sur la triangulation des données : interview et questionnaires proposés aux parents, questionnaire adressé aux moniteurs et interviews semi-structurées réalisées auprès de 10 experts de la psychomotricité et/ou des prématurés (pédiatres, kinésithérapeutes, logopèdes, psychologues, psychomotriciens). Une analyse de contenu a été réalisée afin de dégager les éléments de sens qui ont été compilés. Les différents acteurs s’accordent sur la majorité des éléments proposés dans les activités (contenu, matériel, espaces, diversité) et sur l’organisation (structuration, jeux libre, binôme kinésithérapeute-éducateur sportif). Des ajustements paraissent nécessaires au niveau de la phase d’accueil et du rituel de fin de séance. La présence des parents durant l’activité fait débat. Le projet a été initialement bien pensé et la majorité du concept a été validée par les experts. De légères adaptations ont été programmées. Cette étude renforce la crédibilité de l’initiative dont l’intérêt a été chaleureusement salué par les parents. [less ▲]

J Strength Cond Res 24(x): 000-000, 2009-The purpose of this study was to investigate the ability of the load-velocity relationship to accurately predict a bench press 1 repetition maximum (1RM). Data from 3 different bench press studies (n = 112) that incorporated both 1RM assessment and submaximal load-velocity profiling were analyzed. Individual regression analysis was performed to determine the theoretical load at zero velocity (LD0). Data from each of the 3 studies were analyzed separately and also presented as overall group mean. Thereafter, correlation analysis provided quantification of the relationships between 1RM and LD0. Practically perfect correlations (r = approximately 0.95) were observed in our samples, confirming the ability of the load-velocity profile to accurately predict bench press 1RM. [less ▲]

Objective: The purpose of this study is to assess the relevance of a technological innovation (Mi-Scan function, Compex company) offered by the range of rehabilitative and/ or sport oriented stimulators. This analysis examines the effectiveness to induce muscle contraction and the reproductibility of this function. Method: A comparison of electrically evoked torques of the quadriceps was performed with and without the aid of this function, both at submaximal and maximal stimulation intensity. Moreover, this function was studied several times under identical conditions (reproducibility study). Results: No superior efficacy has been found when using a system including the "Mi" function over a system that did not use this feature. Additionally, our results have highlighted a poor reproducibility of measurements obtained by the "Mi"sensor. Discussion: Important doubts must be made concerning the validity and reliability of this tool. [less ▲]
