This study measured the effects of gender, age and their interaction on global selfesteem and physical self-perceptions (physical self-worth, PSW; physical condition, PC; physical strength, PS; attractive body, AB; sport competence, SC) of French adolescents. Global self-esteem (GSE) and physical self-perceptions were measured by the Physical Self Inventory. Participants were 605 adolescents assigned to groups on the basis of gender (males vs females) and age (from 11 to 16 years). Significant age, gender and interaction differences in the ratings were analysed using a two-way MANOVA design. An age effect was found on the GSE, PSW and AB scales and a gender effect was found on GSE and all physical self-perception scales. We found no interaction (age gender) effect. We discuss the separate effects of gender and age on GSE and physical self-perceptions in adolescents, as well as the lack of interaction effect.

The purpose was to examine the effects of type of program (integrated vs. segregated) and type of sport (basketball vs. swimming) on sport skills, four domains of perceived competence, and general self-worth. Participants were 48 adolescent females with mental retardation (MR) divided equally into six groups: (a) segregated basketball, (b) integrated basketball, (c) segregated swimming, (d) integrated swimming, (e) adapted physical activity (APA), (f) sedentary. The experimental treatment was 8 months long. We administrated sport skill tests and Harter’s (1985) Self-Perception Profile for Children four times to determine changes in sport skill, perceived competence, and general self-worth. Results indicated (a) significant improvement in skill for all sports groups, (b) no changes in perceived social acceptance and physical appearance, (c) significantly lower perceived athletic competence for the integrated basketball group compared to the sedentary group, (d) significantly lower perceived conduct for the basketball groups compared to the APA and sedentary groups, (e) and no significant changes in general self-worth.

The integrated sport participation for adolescents with ID placed in segregated school is useful but needs to be well controlled by professional in physical education.

This study aimed to construct a hierarchy of motives linked to doping behaviors. Between 2000 and 2005, calls to a national antidoping phone-help service by 115 cyclists, 203 bodybuilders, and 40 footballers were analyzed. The results showed that the main motives were preserving health for cyclists, increasing muscular strength for bodybuilders, and personal recreation for footballers. However, in contrast to the literature, group influence was low and health preoccupations were high for cyclists; the influence of body image was relatively low for bodybuilders; and footballers cited muscular strength enhancement as a motive. The study's limitations are noted. The prevention campaigns therefore need to be specific.

The purpose of this study was to examine the effects of alternated (segregated and integrated) basketball competition on two domains of perceived competence and on general self-worth. Participants were 24 adolescent males with intellectual disabilities divided equally into three groups: (a) those involved in basketball in an alternated sport competition, (b) those involved in adapted physical activity, and (c) those who were sedentary. The experimental treatment lasted for 13 months. For the sport competition group this involved 2 hr of training each week and 12 competitive meets. We administered Harter's (1985) Self-Perception Profile for Children 13 times to determine changes in perceived competence and general self-worth. The results indicate no significant changes for the different groups in the two domains of perceived competence and in general self-worth over 13 months.
