Consumo de proteína por praticantes de musculação que objetivam hipertrofia muscular

Abstract

The high demand for health clubs is often related to aesthetics and in most cases to increase of muscle mass, especially by practitioners of bodybuilding. There is a belief among athletes that additional protein (LWA) increases strength and improves performance. This study aimed to evaluate the protein consumption of bodybuilding practitioners aiming muscle mass increase, in a health club from Rio Grande do Sul. The sample consisted of 23 male bodybuilding practitioners, aged between 19 and 33 years. Bodybuilding practitioners who trained to gain muscle mass with minimum frequency of three times per week and had experience in endurance training for at least twelve weeks participated in the study. A form with personal information and some specific data concerning training and nutrition was filled out. Food record was held for three days. The anthropometric measurements were taken from the physical evaluation software database of the health club. Nutritional status was also assessed by the calculation of the Body Mass Index (BMI). Average protein intake was 1.7 g / kg. The current lean mass (61.7 kg) presented values higher than the initial lean mass (59.9 kg), which was lower for the three LWA intake classifications (low, recommended and above recommended). Statistically significant difference was detected for the classifications within the recommended range (p <0.001) and higher than recommendation (p <0.05), where, in both situations, the current lean mass was significantly higher than the initial lean mass. The findings in this study suggest that the sample is not characterized by the consumption of LWA above or below the recommendation, and presents hyperprotein diet feature.

Prevalence and profile of users and non-users of anabolic steroids among resistance training practitioners

“…Thus, it was indicated that individuals who use AS are more likely to use supplements [13, 22]. In our results, protein was the most common supplement used, in accordance with previous studies [13, 14, 16], because protein supplements help to achieve muscle hypertrophy, which is one of the objectives of these practitioners [38]. Also, the addiction must be considered as a potential complication of innapropriate use of AS [39].…”

Avaliação da percepção do tamanho de porções de alimentos proteicos

“…Para que o nutricionista possa realizar a intervenção adequada é essencial que haja o um detalhamento fidedigno do entrevistado em relação ao tamanho da porção, medida caseira e lista de ingredientes utilizada no preparo e consumo dos alimentos. Diversos estudos tem mostrado consumo inadequado de proteínas em indivíduos ativos e sedentários [12][13][14][15][16] . Qual a realidade desses dados?…”

Conhecimentos em nutrição para o esporte e consumo de suplementos por praticantes de musculação em uma rede de academias

“…Acrescentando-se ao uso indiscriminado de suplementos nutricionais no âmbito da musculação, relata-se a efetivação de práticas alimentares inadequadas, observando-se certa supervalorização da ingestão proteica em detrimento do consumo de carboidratos, além da adoção de dietas que vão de encontro aos princípios de uma alimentação adequada, desprezando as vertentes culturais, políticas e éticas [10][11][12] . Tendo em vista a efetivação de práticas de suplementação e nutrição potencialmente inadequadas e seus consequentes prejuízos à saúde, é importante avaliar os conhecimentos em nutrição e as condutas de suplementação e nutrição por parte de praticantes de musculação, de modo a possibilitar planejamentos de educação nutricional e assistência nutricional, contribuindo para a prevenção de danos à saúde e promoção da saúde.…”
