“…Given the central role that body fat plays in adolescent females' self-concept (Dunton et al, 2003;Ecklund & Bianco, 2000), the present finding that the intervention did not bring about reduced body fat supports the hypothesis that the intervention may not have been sufficiently intense to bring about changes in self-concept in this sample. Sedentary, unfit female adolescents may be more likely to experience improved physical self-concept following an exercise intervention that results in reduced body fat.…”

“…The factor loadings of these scales were recently replicated in an American University sample (Nigg et al, 2001). In addition, a study of sedentary female adolescents provided support for the validity of the PSDQ in terms of correlations between the subscales and external criteria of physical fitness and activity (Dunton, Schneider Jamner, & Cooper, 2003).…”

PROBLEM: Physical activity has been promoted as a means of enhancing self-concept, yet the evidence for this connection is far from compelling. In particular, experimental research investigating this association during adolescence, a period during which many youth struggle to maintain a positive self-image, is noticeably lacking. This study investigates the impact on self-concept of a 9-month physical activity intervention among sedentary adolescent females. METHOD: Female adolescents who were sedentary at baseline were assigned either to an exercise intervention or a comparison group as part of the controlled trial. The intervention was school-based, and assignment to groups was based on school attended. Intervention participants engaged in supervised activity 4 times per week and received didactic instruction promoting activity outside of school 1 day per week. Self-concept, physical activity participation, and cardiovascular fitness were assessed before, mid-way through, and after the 9-month intervention. RESULTS: The intervention had a significant positive impact on participation in vigorous activity and cardiovascular fitness. The intervention did not significantly influence any of the self-concept dimensions overall. There was, however, a three-way interaction such that there was an increase in global physical self-concept among those intervention participants who increased cardiovascular fitness. CONCLUSIONS: These findings indicate that a physical activity intervention among sedentary adolescent females enhanced global physical self-concept for a subset of intervention participants who manifested positive changes in fitness.

“…Su validez ha sido comprobada en varias investigaciones (Dunton, Jamner y Cooper, 2003;Marsh, Asci y Tomás, 2002;Tomás, 1998 Goñi et al (2006), que evalúa las siguientes dimensiones: habilidad física, condición física, fuerza física, atractivo físico, autoconcepto físico general y autoconcepto general, con adecuados índices de fiabilidad. Sin embargo, y aunque ha sido aplicado en numerosos estudios (ver Goñi, 2009), los 1344 participantes del estudio inicial (Goñi et al, 2006) eran estudiantes de ESO, Bachillerato y Universidad, con edades comprendidas entre los 11 y los 26 años y pertenecían a las provincias de Álava, Guipúz-coa, Vizcaya, Burgos y La Rioja.…”

ResumenLos objetivos de este trabajo fueron examinar la estructura factorial del CAF (Cuestionario de Autoconcepto Físico) en un contexto distinto al de su creación así como averiguar las posibles relaciones de sus dimensiones con el rendimiento académico (global y en Educación Físi-ca) y si éste se puede predecir a partir de las mismas. Los participantes fueron 574 estudiantes de ESO de la Comunidad Valenciana. Se llevaron a cabo análisis factorial confirmatorio, correlacional y de vías. Los resultados obtenidos revelan que el CAF muestra adecuados índices de fiabilidad y de discriminación, así como unos índices de ajuste aceptables, aunque, el cuestionario logra un mejor ajuste y una mayor capacidad de discriminación media si se elimina un elemento del mismo. Por otro lado, se encuentran relaciones positivas entre todas las dimensiones del cuestionario y el rendimiento en Educación Física, y negativas entre algunas de las dimensiones y el rendimiento global.

AbstractThe objetives of this study were to examine the factorial structure of the CAF (Questionnaire of Physical Autoconcept) in a different context of it´s creation as well as to verify the possible relations of his dimensions with the academic performance (global and in Physical Education) and if it would be possible to predict from those ones. The participants were 574 students of ESO from Valencian Community. There was carried out the confirmatory factorial, correlacional and path analysis. The results obtained reveal that the CAF shows suitable indexes of reliability and average discrimination, as well as a few acceptable indexes of adjustment, though, the questionnaire achieves a better adjustment and a bigger capacity of discrimination if an element of the same one is avoided. On the other hand, they find positive relations between all the dimensions of the questionnaire and the performance in Physical Education, and negative between some of the dimensions and the global performance.

“…This is an important study finding, as body image and appearance have emerged as important factors in physical activity decision making among adolescent girls (Biddle & Fuchs, 2009;Biddle, Whitehead, O'Donovan, & Nevill, 2005). Furthermore, evidence suggests that level of body fat is an important predictor of adolescent females' self-concept (Dunton, Schneider Jamner, & Cooper, 2003). This study has shown that 8-weeks of resistance training improves body composition , which in turn, improves perceived body attractiveness in adolescent girls.…”

Objectives. While it has also been suggested that resistance training may have a beneficial effect on psychological health in young people, evidence supporting this assertion is limited. The primary aim of this study was to explore the effect of free weights and elastic tubing resistance training on physical self-perception in adolescents. Design. Randomized controlled trial. Method. Participants (N = 108, mean age = 14.96 ± .68 years) were randomized to free weights (n = 37) or elastic tubing (n = 41) resistance training groups and a control group was recruited (n = 30). Participants in the resistance training groups completed workloads of 2 sets of 10-12 repetitions on 10 exercises for 8 weeks. Height and weight were measured and bio-electrical impedance analysis was used to assess body composition (body fat %). Muscular strength was assessed using 1 repetition maximum tests for bench press and leg press. Students completed the Children's Physical Self-Perception Profile and two scales developed for the current study to assess resistance training self-efficacy and outcome expectancy. Results. Physical self-perception remained stable among boys over the study period. Girls in the free weights resistance training group significantly increased their perceived body attractiveness (p < .01, d = .76) over the study period. The relationship between changes in body fat % and body attractiveness in girls was inverse and marginally significant (r =-.28, p < .10). Conclusion. Resistance training programs may improve physical self-perception in adolescent girls. However, additional studies with larger sample sizes and more heterogeneous samples are required to confirm this finding. Physical Self-Perception and Training 3 3 The Effects of Free Weights and Elastic Tubing Resistance Training on Physical Self-Perception in Adolescents Resistance training is exercise designed specifically to increase muscular strength and endurance through increased workload demand and may include the use of free weights, machine weights, elastic tubing/stretch bands, hydraulic machines or body weight (e.g. push-ups, chin-ups) (Stratton et al., 2004). Resistance training has long been considered an important activity for adults and the latest physical activity recommendations for youth, adults, and older adults now include guidelines for resistance training (U.S. Department of Health & Human Services, 2008). Historically, resistance training was not recommended for children and adolescents, due to the perceived threat of injury (Faigenbaum, 2000). However, recent studies have shown that supervised resistance training programs do not appear to have any adverse effects in children and adolescents (Malina, 2006) and in fact may improve cardiovascular fitness, body composition, bone mineral density and blood lipid profiles (Benson, Torode, & Fiatarone Singh, 2008b;
