Relationship between body mass index with dietary fiber intake and skinfolds-differences among bodybuilders who train during morning and nocturne period

Background: The prevalence of overweight individuals has increased in recent years. Moreover, the importance of a healthy diet is associated with the practice of physical activity and attempt to verify the achievement of physical exercise influences on food choice. However, it relationship between food intake and physical activity have not been studied. Aim: To evaluate if the period in which the trainings are conducted, morning and nocturne, interfere qualitatively and quantitatively in food consumption as well as verify possible associations between anthropometric profiles and dietary habits. Methods: We collected data from 33 adult volunteers, between men and women, practitioners of bodybuilding. Results: A total of 33 volunteers were interviewed (18 (54.5%) were men and 15 (45.5%) were women). Regarding anthropometric data, it turns out that that the volunteers of the two periods had similar characteristics, differentiating only weight. The consumption of nutritional supplements was observed in 30.77% of the practitioners in the morning period vs. 35% for the nocturne. Considering macronutrient intake, there was a significant difference in the consumption of protein between the periods. The consumption during nocturne period was greater (126 +/- 5% of the daily requirement) than the morning period (115.7 +/- 2%). As for micro-nutrients, calcium intake was greater among men when compared to women. There was a positive correlation between the BMI, and arm circumference for practitioners of the morning period. Conclusion: This study show that the practitioners who train in the morning have quietly better eating habits than those in the nocturne period, however both are inappropriate.

Precompetition dietary practices of competitive male and female bodybuilders

A comprehensive analysis of precompetition dietary beliefs and behaviors of competitive bodybuilders has yet to be documented in the literature. The purposes of this study were (a) to quantify and document types of supplements competitive male and female bodybuilders consume, (b) to document how much money they spend on them each month, (c) to describe what dietary modifications and behaviors they follow in preparation for a contest and (d) to describe their nutrition beliefs associated with these habits. Three hundred and nine competitive male and female bodybuilders completed questionnaires regarding their precompetition dietary practices. It was found that bodybuilders consume a wide variety of supplements and use a multitude of dietary training practices which vary depending on the training phase. A large percentage of bodybuilders agreed with statements on supplement use and training practices that are unsubstantiated by scientific research.

Being online, living offline: The influence of social ties over the appropriation of social network sites

Research on social network sites has examined how people integrate offline and online life, but with a particular emphasis on their use by friendship groups. We extend earlier work by examining a case in which offline ties are non-existent, but online ties strong. Our case is a study of bodybuilders, who explore their passion with like-minded offline 'strangers' in tightly integrated online communities. We show that the integration of offline and online life supports passion-centric activities, such as bodybuilding.

"Hey world, take a look at me!": Appreciating the human body on social network sites

Social network sites (SNSs) such as Facebook have the potential to persuade people to adopt a lifestyle based on exercise and healthy nutrition. We report the findings of a qualitative study of an SNS for bodybuilders, looking at how bodybuilders present themselves online and how they orchestrate the SNS with their offline activities. Discussing the persuasive element of appreciation, we aim to extend previous work on persuasion in web 2.0 technologies.

Perfil morfológico de culturistas brasileiros de elite em período competitivo

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Antropometria de atletas culturistas em relacao a referencia populacional

Body builders have as their training goals the maximum muscle hypertrophy with minimum adiposity. However, the scarcity of specific standards implies often in framing wrongly those athletes either as overweight (by their BMI) or energy malnourished (by their fat stores). The objective of this study was to compare the body composition of body builders with population standards. Thirty-six adults, 26 male (27.2 ± 7.2 years) and 10 female (30 ± 6.1 years) nationwide competitive body builders, were assessed considering weight, height, body mass index, adiposity, arm and leg circumferences and skinfolds. The data were referred either as percentile or standard deviations (Z score) of population standards. Body weight and height were among the closest values from the populational mean whereas upper arm muscle circumference (for men) and body adiposity (for women) were the farterest. By using fat parameters as indicators of their protein-energy status, the undernourishment was found in 88.5% of men and 100.0% of women. Thus, it seems that body builders deserve their own anthropometric standards to avoid nutritional status misplacements.

Differential effects of variation in athletes training on myocardial morphophysiological adaptation in men: Focus on I-123-MIBG assessed myocardial sympathetic activity

High intensity systematic physical training leads to myocardial morphophysiological adaptations. The goal of this study was to investigate if differences in training were correlated with differences in cardiac sympathetic activity.58 males (19-47 years), were divided into three groups: strength group (SG), (20 bodybuilders), endurance group (EG), (20 endurance athletes), and a control group (CG) comprising 18 healthy non-athletes. Cardiac sympathetic innervation was assessed by planar myocardial I-123-metaiodobenzylguanidine scintigraphy using the early and late heart to mediastinal (H/M) ratio, and washout rate (WR).Left ventricular mass index was significantly higher both in SG (P < .001) and EG (P = .001) compared to CG without a statistical significant difference between SG and EG (P = .417). The relative wall thickness was significantly higher in SG compared to CG (P < .001). Both left ventricular ejection fraction and the peak filling rate showed no significant difference between the groups. Resting heart rate was significantly lower in EG compared to CG (P = .006) and SG (P = .002). The late H/M ratio in CG was significantly higher compared to the late H/M for SG (P = .003) and EG (P = .004). However, WR showed no difference between the groups. There was no significant correlation between the parameters of myocardial sympathetic innervation and parameters of left ventricular function.Strength training resulted in a significant increase in cardiac dimensions. Both strength and endurance training seem to cause a reduction in myocardial sympathetic drive. However, myocardial morphological and functional adaptations to training were not correlated with myocardial sympathetic activity.

Avaliação do consumo alimentar e percepção da imagem corporal de culturistas

In bodybuilding, sport that emerged in Brazil in the 70s, competitors are judged by physical appearance, size and muscle definition. The present study aimed to assess dietary intake, supplement use, and it also investigated body image perceptions of bodybuilders. Practitioners of three different gyms in the state of São Paulo participated in the study. They filled the anamnesis form containing data on food consumption and intake of supplements and also answered a questionnaire on the perception of body image (Satisfaction Scale with Body Appearance). The study showed a considerable food inadequacy with an average of carbohydrate intake of 41.84% ± 10.88%, of lipid, an average of 18.96% ± 6.40% and of protein 39.20% ± 10.41%. In pre-competition, the average of daily carbohydrate intake is reduced to 22.69% ± 12.34%, the lipid increases to 25.68% ± 14.0% and the protein increases to 51.63% ± 10.28%. It was observed that all individuals take some sort of supplement. Considering the perception of body image 60% of the appraised are fully satisfied with the muscular appearance and 40% has greater risk of developing vigorexia. As the bodybuilder has rigid dietary control, it is important nutritional monitoring. So it is necessary a better identification and guidance of risk groups for the development of body image disturbances through specialized professionals such as dieticians, psychologists and coaches for success training, aiming at physical and mental well being of the athletes.

Influência de aspectos psicológicos nos praticantes de musculação

This paper deals with psychological aspects involving bodybuilders nowadays, through their interests, motivations, factors that favor them to practice physical activity, frequent body image disorders, and major benefits that can be acquired when weight training the right way, whether physical or psychological. During the work is addressed to the Theory of Self-Determination and its characteristics, and behavioral aspects of the individual. We explore the types of motivation, intrinsic and extrinsic motivation, and their regulatory mechanisms. Did the relationship with weight training and the environment that surrounds it as the interaction between those involved in practice between the student and teacher performance and results and the effects that this interference can have on motivation and individual behavior. Also we relate body image factors, the perception of bodybuilders in relation to his own body, and the possible disorders that can promote. Describe the Vigorexia and their characteristics, we made a list of body image and self-esteem, approach standards set by society, the aesthetic influence and media disclosure. Finally, we explore the key benefits that well-directed physical activity can provide its practitioners. Physical, mental and social beneficial, improved self-esteem and in one's relationship skills. We address the growing strength in recent years, and their improvements in the various age groups and the population's quality of life

Uso de substâncias ergogênicas suplementares nutricionais em praticantes de musculação

Ergogenic substances are all nutritional or pharmacological additional devices which physiologically influence on the individual's performance. Currently, the practice of physical exercises that modern gyms have is growing and embracing a new recreational space for the population. In particular, for the male audience, weight training; and for the female audience, aerobic gymnastics. This study has the objective of explaining the importance of ergogenic resources in the physiological and psychological planes, emphasizing the point that supplementation is really valid and beneficial. To achieve the objective of the study, a literature review will be carried out, searching for scientific articles published in books, magazines and online newspapers that address some issues that cut across the thematic proposed in this work. From the point of view of Sport Psychology, the issues discussed on body image and emotional changes have concerns professionals of this area, but the literature suggests it is unnecessary the use of ergogenic substances to the concreteness of that purpose. Supplements of any kind will not be enough to transform the psychological and physiological aspects, the way the media assume conclusively. Thus, with our documentary research, we started a provocation that feeds new studies in the area. We conclude that supplementation is a resource that should be used in the final occasion, that is, if the bodybuilders (non-athletes) have time to be nourished from the normal diet, the use of supplements like whey and creatine, are not needed. Used appropriately supplements do not result in physiological damage, however, can contribute beneficially to the individual's nutrition, thus the abusing dosages, in addition to financial loss, can cause damage to the body
