The brief body avoidance and checking scale for physically active men: development and initial validation
The aim of this study was to develop and examine the psychometric properties of the Brief Body Avoidance and Checking Scale (BBACS) for physically active men. The BBACS is designed to assess the frequency of body checking and avoidance behaviors common among users of gyms and health clubs. Following development of an initial pool of items and content judgment, data from 325 men were collected from gym users and participants in organized sporting events. Confirmatory factor analysis showed a good fit for a model with two factors and 12 items. Satisfactory evidence of construct validity and internal consistency was also generated through analysis of factor loadings, t-values, correlations with drive for muscularity and body satisfaction measures, group differences, Cronbach’s alpha, and construct reliability tests. The BBACS appears to be a valid and reliable scale for assessing the frequency of body checking and body avoidance behaviors among physically active men
Factors Associated With Inappropriate Eating Behavior In Adolescent Students [fatores Associados Ao Comportamento Alimentar Inadequado Em Adolescentes Escolares]
Background: Evidence shows that the prevalence of inappropriate eating behavior (CAI) among young people has increased in recent years. It seems that body dissatisfaction (IC), the practice of excessive exercise, body composition, the socioeconomic status (NE), and ethnicity may be risk factors for CAI. Objective: To associate IC, degree of psychological impairment to exercise (GCPE), adiposity (AC), nutritional status (EN), NE and ethnicity with CAI in adolescents. Methods: Participants 362 young people of both sexes aged between 10 and 19 years. We used the Eating Attitudes Test to assess the CAI. The Body Shape Exercise Questionnaire and Commitment Exercise Scale were used to measure IC and GCPE, respectively. We evaluated skinfold thickness is to classify the AC second sex. Weight and height were measured to calculate the index of mass (BMI) and classify the EN. The NE was evaluated by Brazil Economic Classification. Questionnaire was used that sought to assess ethnicity, age and sex. Results: The results showed association of CAI with IC, GCPE and NE in females (p < 0.05). Among boys, IC, AC and EN were associated with CAI (p < 0.05). Discussion: It was concluded that IC was the main predictor of risk for the CAI.4025964Development of a WHO growth reference for school-aged children and adolescents (2007) Bulletin of the World

How Persons With Congenital Blindness Perceive Facilitators And Barriers For The Practice Of Physical Activities [facilitadores E Barreiras Percebidos Por Pessoas Com Cegueira Congênita Para A Prática De Atividade Física]
The physical activity is an important element for a healthy lifestyle. However, among people with visual impairments, this practice is reduced, which makes this group as being at risk for developing diseases associated with physical inactivity. This study aims to investigate facilitators and barriers perceived by persons with congenital blindness to physical activity. Two focus groups were conducted with eleven subjects with congenital blindness, six female and five male, age mean 34 years (+7 years). The results showed two broad categories: "main facilitators to physical activity" and "main barriers to physical activity". The facilitators (family, specialist Physical Education teachers, adapted materials, and recognition of the benefits) and barriers (family, unprepared Physical Education teachers, limited infrastructure in physical activity centers, feelings of exclusion in Physical Education classes, difficulty in spatial ability and motor coordination) reported by participants were complex and multifaceted, with social, environmental and personal origins. Considering the benefits of physical activity, it is essential that professionals adapt strategies for inclusion and appropriate participation of the congenitally blind, enabling them to explore different possibilities of movement and relationship to the world, which may act positively on the biological, psychological and social development.193379394Adelson, E., Fraiberg, S., Gross Motor Development in Infants Blind from Birth (1974) Child Development., 45, pp. 114-126. , MaldenArditi, A., Holtzman, J.D., Kosslyn, S.M., Mental Imagery and Sensory Experience in Congenital Blindness (1988) Neuropsychologia, 26, pp. 1-12. , DallasArdito, M., Roberts, J.J., A Catalog of Physical Activities for Visually Impaired Youth (2007) Electronic Projects Collection, pp. 8-65. , WorcesterBardin, L., (1977) Análise de conteúdo, p. 70. , Trad.

Drive For Muscularity: An Exploratory Study In The Brazilian Army [drive For Muscularity: Um Estudo Exploratório No Exército Brasileiro]
Drive for muscularity refers to the desire to achieve an ideal muscular body, as well the degree of concern about increasing muscle mass. The aim of this research was to investigate drive for muscularity traits in men from the Brazilian army. Data from a non-probabilistic sample of 652 men were analyzed. Results showed associations among drive for muscularity variables and habits of physical exercise practice, life and body satisfaction, and social physique anxiety. Differences in drive for muscularity traits were also found accordingly with the romantic status, financial security and time career in the army. It was concluded that monitoring the drive for muscularity during military education should be part of the psychosocial care routines.302213222Bahrke, M.S., Muscle enhancing substances and strategies (2007) The muscular ideal: Psychological, social and medical perspectives, pp. 141-160. , J.
