Nowadays practicing bodybuilding is increasing among individuals, whether due to concern with esthetics or the pursuit of a healthy lifestyle. However, the information related to the pre-workout nutrition is scarce, resulting in food myths among athletes and resulting in inadequate dietary intake. The objective of this study was to identify the food consumption and its adequacy on pre-workout of practitioners of weight training in gyms in the cities of Santa Cruz do Capibaribe and Surubim, Pernambuco. Have been assessed 114 practitioners of weight training aged between 18 and 30 years. It was observed that 95.6% of practitioners of weight training studied consumed carbohydrates inadequately, so they are more prone to hypoglycemia, to decreased performance and muscle mass due to the impairment of the process of muscle contraction for lack of energy, to negative impacts in the immune system, to losses in metabolism of adipose tissue and muscle fatigue early. There needs to be a better guidance regarding appropriate feeding prior to exercise, with the support of a sports nutritionist. This will help create habits of nutritional behaviors most appropriated, thereby improving the performance and the quality of activity performed. Key words: Foods for Persons Engaged in Physical Activities, Carbohydrates, Resistance Training.

Dissatisfaction with its own image seems to be a common occurrence on general population. People with low self-esteem and difficulties in interpersonal relationships may frequently reject or accept the suffering with their own body image and, in some cases; this phenomenon may be described as muscle dysmorphia or, as also called, vigorexia. The dependence of women self-esteem upon their appearance make them more vulnerable to negative body image, the literature presents most of the studies with male individuals and thus, the interest in assessing the prevalence of vigorexia signs and symptoms in women. Thirty-seven women with mean age of about 29,05 ± 9,237, who practitioner physical activities in two academies in the city of Santa Maria/RS were interviewed. These women responded the “Adonis Complex Questionnaire” which consists in understanding the way image concerns may affect the population daily-life. This questionnaire is a set of 13 questions (A, B, C), with scores that give the raw index showing the gravity of body image concerns. The results demonstrated that the interviewed women have a concern about their body image but, it does not affect their daily-life being considered a female vanity. The educational level of the interviewed was complete higher education (35,1% n = 13), bodybuilding practitioners (45,9% n = 17) from which 37,8% n = 14 reported that the reason for the practice was weight loss and muscle toning. The statistical analysis was performed using the software SPSS version 18.0. It is possible to conclude that women pursue the thinness ideal while men seek to be stronger and larger. Key words: Body image, Obsessive compulsive disorder, Low self-esteem.

We have seen a greater adherence of individuals in gyms, and in view of the intimate relationship between exercise and nutrition, should be emphasized to caloric intake of individuals who adopt this practice This study aimed to evaluate the intake of macronutrients (carbohydrates, lipids and proteins) in users of gyms in the city of Pau dos Ferros/RN. This descriptive research in their sample had an number of 118 individuals aged between 18 and 30 years, which corresponds to approximately 35% of users of that city academies. The used instrument for data collection was the 24-hour Food Recall, besides questions about supplementation. For statistical test, we applied the ANOVA. Of the 118 interviewed, 59 (50%) have hypoglycemic diet, 72 (61%) achieved diet and 74 (63%) have hyperproteic diet, where men consume more protein than women. A total of 59 (50%) not using supplements. In the group studied, it was found that men (61, 7%) are more adept to supplements than women (38.3%). With relation to the macronutrients intake among men and women that ingest supplement, both showed hypoglycemic diet; normolipídica and hyperproteic, being amino acids and proteins the most consumed (34%), where the majority (37%) showed muscle hypertrophy as main goal. Therefore, from this study we can conclude that users of gyms in Pau dos Ferros have a deficient diet in carbohydrates, and on the other hand, there is the excessive intake of protein.

The implementation of pre-exercise meal is indicated in order to avoid hypoglycemia during physical activity. A nutritionist is the most indicated person to do the orientation and awareness of the athletes diet, in order to have a good performance, especially in competitive terms. The present study aimed to assess dietary intakes before the physical activity of gym-goers in different modalities. We conducted a survey with 274 people between 18 and 60 years old, which were interviewed before, during and at the end of their physical activities. They were selected at random, with no restriction on the sport. Among the results, a total of 84% are used to eat before exercise, 41% eat 30 minutes before. On the group of carbohydrate, 57% eat bread, on the group of protein, 66% consume milk and dairy products, fruits 78% and vegetables 22%, juice 68% and supplements 68%. The physically active regularly consume some food before the exercise. An inadequate diet can affect the health and the performance of these people, and when properly oriented can reduce fatigue. Nutritional counseling is needed for further clarification regarding the choice of the right foods to eat on a pre-exercise meal. Key words: Food, Exercise, Physical Performance and Nutrition.

Objective: To investigate the literature on the effects of physical exercise on the formation of reactive oxygen species and dietary antioxidant compounds. Materials and Methods: This is a literature review with emphasis on the past 10 years, using scientific articles indexed in SciELO, PubMed and Lilacs databases, periodic CAPES Portal and book chapters, in Portuguese, English and Spanish. Results: The literature indicates that, regardless of the type of exercise performed, individuals who undergo strenuous exercises are exposed to a deleterious process in cells and tissues, a loss in performance, with a reduction in body stores of antioxidants may contribute significantly to the increased oxidative stress. Conclusion: Regular exercise, combined with a diet rich in antioxidant nutrients, can promote the body benefits by keeping the oxidative process within physiological limits, but more studies are needed on the origin of oxidative stress in order to develop new strategies to combat the deleterious effects of this phenomenon. Key words: Physical activity, aerobic exercise, free radicals, oxidative stress, antioxidants.
