L'objectif de cette étude consiste à déterminer les particularités des paramètres de nage : vitesse (V), fréquence (F), amplitude (A) et l'indice de nage (IN), qui caractérisent les jeunes nageurs, en fonction de l'âge du sexe et des caractéristiques anthropométriques.78 jeunes nageurs non experts, âgés de 10 à 12 ans ont été évalués en situation de compétition sur les épreuves du 50m dans chaque style de nage.Les résultats montrent que (V) augmente significativement en fonction de l'âge et des caractéristiques anthropométriques. D'autre part on enregistre des corrélations hautement significatives entre (V) et les caractéristiques anthropométriques retenues (r = 0,67 à 0,89 p<0,001), ces relations apparaissent principalement avec l'amplitude de nage (r=0,56 à 0,89 p<0,001), inversement les caractéristiques anthropométriques n'explique pas l'élévation de la fréquence dans la majorité des épreuves. On peut retenir que les corrélations entre (V) et (A) sont plus fortes dans les quatre styles de nage, (r=0,78 à 0, 93 p<0,001), comparativement à la relation vitesse fréquence, qui enregistre des coefficients moins déterminant. Cependant, on peut conclure que l'amplitude et l'indice de nage restent les meilleurs indicateurs de l'efficacité propulsive et du niveau de préparation.

Purpose: The Aim of this study is to determine the peculiarities of the swimming parameters: speed (S), stroke rate (SR), stroke length (SL) and stroke index (SI), that characterize young swimmers in the four swimming modes, according to age, (46 boys and 32 girls), aged between 10 and 12 years old, were evaluated in competition on the 50m events in each swimming style, (freestyle, backstroke, breaststroke and butterfly), from video recordings of the 3rd 2015 Young Talent Contest.Results: The results show that (S), increases significantly with age and characteristics, in the four swimming styles,both for boys and girls, overall the most marked differences were observed between 10 and 12 years and less importantly between 11 and 12 years.In freestyle, there is a significant evolution of (SL) according to age in both sexes, while the frequencies do not change much, In backstroke the evolution of (SL) according to age is more important for boys, conversely for girls, there is a significant change in the (SR). In butterfly we can note that the evolution of (S) according to age can be explained in particular by the evolution of (SR), however, in breaststroke this evolution is related in the same time to (SL) and (SR) only in boys. It seems that Boys and Girls are adopting more or less different solutions to improve their speeds according to age and the style of swimming. In all events, (SI) progressed significantly according to age in both sexes. However the comparisons between boys and girls of the same age do not reveal any significant differences. In that way P.Pelayo and al. (1997) have shown that differences in (SI) between boys and girls do not appear during the first years, but they begin to appear during puberty from 14 years old.On the other hand, very highly significant correlations were found between (S) and the characteristics retained (height, weight and span) for all races of the four swimming styles, in both sexes, (r = 0.67 to 0.89 p <0.001), these relationships appear mainly with SL (r = 0.56 to 0.89 p <0.001), conversely the of the events.The results of this study also show the close relationship between competitive (S) and its two components, it can be noted that the correlations between (S) and (SL) are stronger in all four swimming styles, registered correlations were ranged from 0.78 to 0.93 for boys and from 0.77 to 0.94 for girls for p <0.001, comparatively to the speed stroke , which recorded less decisive coefficients, ranging from 0.29 to 0, 39 for boys and 0.35 to 0.47 for girls.
