Description : Les grandes lignes de l'histoire du cinéma afro-américain nous révèlent que ce sont les problématiques de visibilité et de représentation qui ont poussé les premiers cinéastes noirs à prendre possession de la caméra. En réponses aux problématiques de visibilités, qui pointaient du doigt le manque cruel de personnes noires au grand écran, les cinéastes noirs ont émergé avec les films raciaux qui se vantaient de leurs castings entièrement noirs afin de souligner leurs actes contestataires. En réponses aux problématiques liées à la représentation, pointant du doigt les rôles stéréotypés constamment assimilés aux afro-américains, il s'agissait pour les cinéastes noirs d'écrire leurs propres scénarios, afin de contredire ces clichés négligents. A travers ce travail de recherche, résolument pluridisciplinaire, il s'agira d'analyser le cinéma afro-américain des années 90 en tant que cinéma réaliste, témoignage de l'expérience urbaine.

Résumé : International audience
Afro-­‐‑ Caribbean sprinters often reach high performance levels at an early age. Adolescence is a time of morphological and physiological changes. This study was designed to analyze the evolution in parameters of short sprint performance during adolescence in Afro-­‐‑ Caribbean boys, especially the stride number/body height ratio (SN/BH), which is at the interface of technical and morphological factors. Seventy-­‐‑ one 13-­‐‑ year-­‐‑ old boys performed vertical jumps and short sprint races. The races were filmed with a view to determine stride variables. Anthropometric parameters were also measured. The same tests were performed two years later. Body height and SN/BH were the main predictors of sprint performance. The delta of performance was principally explained by stride length and stride number. Although deterioration in technical parameters was expected, the parameters related to body size and stride length were the main sprint performance predictors rather than explosive force. These results could be useful in developing tests to detect sprint potential in youth.
