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 ▲]

Aims of the study : the aim of the present study was to explore the interest of inertial load-velocity and load-power relationships for establishing resistance training zones. Materials and methods : 35 subjects went twice at the laboratory. The first session was used to determine bench press one repetition maximal (1RM) while the second session was used to determine load-velocity and load-power relationships by the means of an inertial dynamometer. For each subject four major training zones (maximal velocity, power-velocity, strength-power, maximal strength), defined from the 1RM, were compared to the corresponding training zones defined from inertial load-velocity and load-power relationships. Results: training zones defined from the 1RM are significantly different (p<0,001) from the ones based on load-velocity and load-power relationships. According to load-power and load-velocity relationships results, maximal bench press velocity should be trained from 0 to 23% of the 1RM ; power-velocity should be trained from 25 to 54% of the 1RM ; strength-power should be trained from 54 to 82% of the 1RM and maximal strength should be trained with superior loads. Such muscular profiles defined with inertial dynamometers allow a more acute and individualised prescription for power-velocity resistance training. [less ▲]

AIM: The aim of this study was to investigate the ability of isoinertial assessment to monitor training effects. Both parametric and curve analysis of the results were used to underline the specificity of maximal strength and maximal velocity resistance training methods. METHODS: Twenty-four untrained subjects were randomly assigned into three groups: a maximal strength-training group (heavy loads: 80% to 98% of the one repetition maximum [1-RM]), a maximal velocity-training group (light loads: 25% to 50% of 1-RM) and a control group. All the subjects were tested in bench press exercises before and after the 6-week training period. An isoinertial dynamometer was used to assess velocity and power at four increasing loads: 35%, 50%, 70% and 95% of the 1-RM load. Post-test protocol also included a trial at 105% of the 1-RM load. RESULTS: Isoinertial assessment demonstrated for both training groups significant gains at each load. Some specific adaptations appeared: strength training presented a greater increase for average power (+49%, P<0.001) and average velocity (+48%, P<0.001) at 95% of 1-RM, while velocity training emerged as a more effective way to improve performance at 35% and 50% of 1-RM (+11 to 22%) in comparison with strength training (+7 to 12%). The analysis of power and velocity curves specified that strength training enhanced performance earlier in the movement, while velocity training extended the propulsive action at the end of movement. CONCLUSION: The original combination of parametric and curve isoinertial assessment appears to be a relevant method for monitoring specific training effects. The complementarity of both strength and velocity training programmes underlined in this study could lead to practical applications in profiling training programmes. [less ▲]
