“…Nut consumption by athletes is important, due to their high energy density and contents of monounsaturated fats, proteins (rich in tryptophan, leucine, and histidine), vitamins, minerals, insoluble dietary fiber, phytosterols, antioxidants and phenolic compounds (González, 2008;Yi et al, 2014). Therefore, the almost daily consumption of nuts by the international squash players participating in the present study is adequate.…”

“…Therefore, the almost daily consumption of nuts by the international squash players participating in the present study is adequate. It has been reported that the intake of this group of foods yields improvements in the endurance of athletes due to its contribution to the reserves and utilization of CH through improvement in glucose transport to the synthesis of skeletal muscle and glycogen, which enhances sports performance and reduces biomarkers of oxidative stress and inflammation (Yi et al, 2014).…”

Background: Squash is one of the four most popular racquet sports, practiced by 20 million people worldwide. It is a sport that has been scarcely researched in the area of nutrition, and even less so regarding the dietary habits of its players. The objective of this work is to perform a descriptive and comparative analysis of dietary habits in squash players at the national and international levels. Methodology: A total of 14 international and 28 national players answered a validated food consumption frequency questionnaire. We used a Student´s t-test for independent samples and a χ2 test in the comparative analysis of players of different levels. Results: The results show that there were statistically significant differences between the two groups of players in the consumption of bread (p = 0.016) and nuts (p = 0.008), with a tendency towards statistical significance for eggs (p = 0.064), blue fish (p = 0.057), and white meat (p = 0.069), which the international players consumed with a higher frequency. There were no significant differences in the consumption of fruits, vegetables, or pulses. The two groups had a similar consumption of potatoes, pasta, rice, juices and soft drinks, sweets and snacks, white fish, and red meat. Conclusions: Although it was not possible to estimate the intake and percentage of macronutrients, a possible deficit of carbohydrates and an excess of proteins can be deduced in both groups. In addition, these players do not usually seek advice from dieticians-nutritionists, so the involvement of these professionals in the coaching staff of squash players could improve athletic performance.

A prática regular de atividade física, associada a uma nutrição adequada, rica em nutrientes antioxidantes, garante proteção ao organismo e reduz os riscos de danos celulares ocasionados pela produção excessiva de radicais livres. O objetivo deste estudo foi avaliar o perfil nutricional e o consumo alimentar de antioxidantes de praticantes de corrida de rua, integrantes de uma assessoria esportiva de Brasília, Distrito Federal. Trata-se de um estudo transversal analítico e descritivo, realizado por meio de um questionário estruturado e dois adaptados, contemplando os aspectos sociodemográficos, o conhecimento sobre a importância e o papel dos antioxidantes na atividade física, e a frequência do consumo alimentar de antioxidantes, além de dados antropométricos extraídos dos cadastros dos participantes junto à empresa. O perfil antropométrico demonstrou que 80% dos corredores apresentavam Índice de Massa Corporal (IMC) dentro da faixa de normalidade e 60% encontravam-se acima do percentual de gordura corporal ideal. Observouse que 50% dos corredores não possuem informações suficientes sobre os mecanismos de ação dos radicais livres e dos antioxidantes na prática esportiva e 95% apresentam nível de conhecimento satisfatório quanto à importância de uma alimentação saudável na prevenção de doenças crônicas e do envelhecimento precoce. Dentre os antioxidantes analisados, destacaram-se o alto consumo de zinco e vitamina A e a ingestão inadequada de selênio e flavonoides. Os resultados indicam um consumo alimentar inadequado de micronutrientes antioxidantes e sugerem a necessidade de ações de educação alimentar e orientação nutricional individualizada, visando à adoção de práticas alimentares específicas para a população estudada.

Antioxidantes.The regular practice of physical activity, associated with adequate nutrition, rich in antioxidant nutrients, provides protection to the body and reduces the risk of cell damage caused by excessive production of free radicals. The aim of this study was to evaluate the nutritional profile and dietary intake of antioxidants of street runners, members of a sports advisory group from the Federal District of Brasilia, Brazil. This is an analytical and descriptive cross-sectional study, carried out through a structured questionnaire and two adapted, contemplating the sociodemographic aspects, the knowledge about the importance and role of antioxidants in physical activity, and the frequency of dietary intake of antioxidants, along with anthropometric data extracted from the records of the participants from the company. The anthropometric profile showed that 80% of runners presented a Body Mass Index (BMI) above the normal range and 60% were outside the ideal body fat percentage. It was observed that 50% of the runners did not have enough information about the mechanisms of action of free radicals and antioxidants, and 95% presented a satisfactory level of knowledge concerning the importance of a healthy die...

“…Interestingly, athletes who supplemented with almonds exercised longer than those supplemented with isocaloric cookies, despite the lower carbohydrate content of the almonds [16]. Given the rising popularity of the Paleo diet, which favors high protein intake and lower carbohydrate intake, this food-based study is particularly timely.…”

“…In contrast to the studies of macronutrients above, Yi et al employed a randomized cross-over design to compare a 4 week intervention of 75 grams of almonds per day compared to isoenergetic cookies on distance covered in a 20 minute cycling time trial [16]. They found the almond group was able to ride further than the cookie group (21.9 vs 20.2 km).…”
