The influence of recreational gymnastics at 4 to 6 years of age on physical activity levels at 8 to 10 years of age
Poster sessions Un kit de mini-bad est offert et comporte différents objets qui permettront une adaptation du badminton à ce public et une progression optimale vers des habiletés motrices complexes : l’apprentissage du geste de frappe (ballons de baudruches, indiaca, raquettes adaptées. . .), l’agilité et la coordination (cordes à sauter, échelle rythmique. . .), etc. La mallette pédagogique (nombreuses fiches de jeux) aidera le moniteur à proposer des exercices progressifs adaptés aux enfants. Analyse critique Aspects positifs essentiels : — travail équilibré d’apprentissage technique et de développement moteur global ; — découverte ludique du sport et possible affiliation en club par après ; — gratuité pour les écoles ou clubs, prix modiques pour les participants. Cependant, il est indéniable que le budget investi est important et qu’il n’existe pas forcément, dans l’entité où les sessions se déroulent, de club de badminton pour prendre le relais. Conclusion Le fil rouge du projet reste le développement moteur harmonieux de l’enfant. Cette structure répond aux recommandations actuelles qui préconisent, parallèlement à un apprentissage d’habiletés techniques spécifiques à un sport chez les enfants de moins de 10 ans, de continuer à enrichir leur motricité via des exercices non spécifiques au sport en question.

The influence of recreational gymnastics at 4 to 6 years of age on physical activity levels at 8 to 10 years of age D. Hillis ∗ , A.D.G.

Introduction With the known health benefits of physical activity (PA), much attention has been spent investigating the effects of early PA participation in childhood on lifelong participation rates and adult health benefits. What is unknown is whether early childhood involvement in specific sports benefits PA levels in later childhood. We hypothesize that early childhood exposure to recreational gymnastics will positively influence PA levels in late childhood. Methods Participants were drawn from the University of Saskatchewan’s Young Recreational Gymnast Study (YRGS). One hundred and sixty three, 4 to 6-year-olds were recruited (91 gymnasts and 72 non-gymnasts). Participants were assessed annually for 4 years. PA was serially assessed using the Netherlands Physical Activity Questionnaire; response range from 7 (low physical activity) to 35 (high physical activity). PA scores were correlated with age. Average PA scores were compared between groups and time points (independent t-test and repeated measures ANOVA) (␣ = 0.05). Results At study entry there were no significant difference in PA scores between gymnasts (25.0 ± 3.0) and non-gymnasts (24.5 ± 3.4) (P > 0.05). The correlation between age and PA score was week (r = 0.12, P > 0.05). PA increased in both groups between study entry and study end (4 years) (P < 0.05), however there was no significant time by group interaction (P > 0.05). Conclusion Although PA did increase in all individuals over 4 years, participating in recreational gymnastics did not appear to significantly influence an individual’s PA level by 8 to 10 years of age. This is probably due to the fact that participation in other sports, in both groups, was influencing PA in late childhood. How-
S31 ever, since PA levels do not start to fall in childhood until early adolescent is reached, the effects of early gymnastic participation may be masked by the effects of normal PA development. Therefore further follow-up of this cohort is warranted.

Introduction The present study aimed to identify anthropometric and functional characteristics of female volleyball players according to their specific positions in the match. Methods The subjects were 17 female athletes (13.88 ± 0.33 years) from a school volleyball team who were included in one of the following groups, according to their specific positions: setter (n = 3), middle player (n = 5), outside player (n = 5), and opposite player (n = 4). Subjects were characterized according to their height, total body mass, arm span, reach of the dominant limb (RDL), explosive strength of the lower limbs (Squat Jump [SJ]), countermovement jump with block (CMJB) and with attack (CMJA), explosive strength of upper limbs (throwing a medicine ball standing [MB]), and speed at 10 m (S10 m). To verify the existence of statistically significant differences among athletes according to their different specific positions, a one-way ANOVA with Tukey’s Post Hoc test was used. Results Average values for anthropometric measures were 160.47 ± 6.44 cm and 52.45 ± 7.20 kg; for arm span, they were 167.65 ± 9.14 cm; and for RDL, 209.71 ± 8.48 cm. Our results revealed significant differences in total body mass among players in different specific positions (P < 0.05), with the opposite players presenting higher values (58.78 ± 8.07 kg) and the middle players presenting lower values (47.42 ± 3.20 kg). No significant differences were observed in the remaining anthropometric variables. Average values for strength were 26.92 ± 5.61 cm in SJ; 35.45 ± 8.04 cm in CMJB; 37.23 ± 6.09 cm in CMJA; 5.70 ± 0.81 in MB; and 2.22 ± 0.25 seconds for S10 m. No significant differences were found among athletes’ positions. Nevertheless, it must be noted that the opposite players revealed higher values in the MB test and the middle players presented the highest values in the CMJ both with block and with attack. Conclusions These results revealed a high level of homogeneity in the sample, mainly in all studied variables, delaying the possibility of discriminating players by position. However, an analysis focused on each player’s maturation status may have produced different results.
