Consumo alimentar e estado nutricional: caracterização de mulheres fisicamente ativas

Few studies have characterized the food consumption and nutritional status of physically active women. The aim of this study was evaluating the food consumption and nutritional status of physically active women. Thirty women aged between 18 and 59 years, who trained at least three times a week, were evaluated. Weight, height, waist circumference (WC), and Body Mass Index (BMI) were checked. The percentage of body fat (%BF) was determined by the seven-skinfold protocol. Food consumption was assessed from the 72 food records collected on non-consecutive days. The records were analyzed using the DietPro 5i Program. The evaluated population had the following anthropometric characteristics: (Weight = 64.13 ± 10.16 kg, Height = 1.64 ± 0.06 m, BMI = 23.91 ± 3.04 kg/m2, WC = 77.48 ± 9.36 cm, %BF = 25.35 ± 4.65); 33% were overweight and 30% had elevated WC. BMI showed a strong and positive correlation with% WC (r=0.70, p<0.001) and with WC (r = 0.84, p<0.001). The average daily consumption of energy and nutrients were: (Energy = 24.5 ± 7.0 Kcal/kg/day, Carbohydrates = 3.1 ± 1.1 g/kg/day, Proteins = 1.1 ± 0.3 g/kg/day, Lipids = 0.9 ± 0.4 g/kg/day, Fiber = 16.7 ± 6.2 g/day, Calcium = 556.2 ± 165.3 mg/day and Iron = 9.8 ± 2.1 mg/day). Most women consumed inadequate energy, carbohydrates, proteins, fiber, and iron. No woman achieved the recommended minimum calcium intake. It is concluded that an expressive portion has BMI, WC and% BF above the desirable values ​​that are associated with healthy nutritional status. In addition, the significant percentage of inadequate consumption of energy, carbohydrates, proteins, fiber, calcium, and iron reveals the need for professional guidance.Poucos estudos têm caracterizado o consumo alimentar e estado nutricional de mulheres fisicamente ativas. Mediante o exposto, o presente estudo teve como objetivo avaliar o consumo alimentar e estado nutricional de mulheres fisicamente ativas. Foram avaliadas 30 mulheres com idade entre 18 e 59 anos, que treinavam pelo menos três vezes por semana. Foram verificados o peso, altura, circunferência da cintura (CC) e o Índice de Massa Corporal (IMC). O percentual de gordura corporal (%GC) foi determinado pelo protocolo de sete dobras cutâneas. O consumo alimentar foi avaliado a partir do registro alimentar de 72 horas coletado em dias não consecutivos. Os registros foram analisados utilizando o Programa DietPro 5i. A população avaliada apresentou as seguintes características antropométricas: (Peso = 64,13 ± 10,16 kg, Altura = 1,64 ± 0,06 m, IMC = 23,91 ± 3,04 kg/m2, CC = 77,48 ± 9,36 cm, %GC = 25,35 ± 4,65); 33% estavam com sobrepeso e 30% tinham a CC elevada. O IMC apresentou correlação forte e positiva com o %GC (r = 0,70, p<0,001) e com a CC (r = 0,84, p<0,001). O consumo diário médio de energia e nutrientes foram: (Energia = 24,5 ± 7,0 Kcal/kg/dia, Carboidratos = 3,1 ± 1,1 g/kg/dia, Proteínas = 1,1 ± 0,3 g/kg/dia, Lipídios = 0,9 ± 0,4 g/kg/dia, Fibras = 16,7 ± 6,2 g/dia, Cálcio = 556,2 ± 165,3 mg/dia e Ferro = 9,8 ± 2,1 mg/dia). A maioria das mulheres faziam consumo inadequado de energia, carboidratos, proteínas, fibras alimentares e ferro. Nenhuma mulher alcançou a ingestão mínima recomendada de cálcio. Conclui-se que parcela expressiva possui IMC, CC e %GC acima dos valores desejáveis que são associados ao estado nutricional saudável. Além disso, os expressivos percentuais de inadequação de consumo de energia, carboidratos, proteínas, fibras alimentares, cálcio e ferro revelam a necessidade de orientação profissional

Visual stimulus does not alter fluid replacement in women practicing Zumba fitness

Hydration is an important component of physical performance. The lack of adequate hydric replacement can lead to severe dehydration and early fatigue. The purpose of this study was to evaluate the effects of using visual stimulation on the hydration status of women Zumba fitness practitioners. Sixteen women practicing Zumba fitness (age = 42.3 ± 12.0 years, weight = 75.6 ± 16.8 Kg, height = 1.62 ± 0.58 m, BMI = 28.3 ± 4.6 Kg/m2, WC = 89.4 ± 10.1 cm, %BF = 38.0 ± 6.0) participated in the study. Hydration status was assessed in three moments: 1) familiarization, 2) usual training (Control) and 3) training with visual stimulus for hydration (VS). Body mass before and after training and fluid intake during training were obtained. Sweating rate (SR), fluid intake rate (FIR), and dehydration percentage (D%) were calculated. Temperature and humidity were recorded during training. Hydration status in the recovery period was assessed using urine specific gravity (USG) and urine color (UC) which were measured on the mornings of the training days and the day after training. Although the workouts were performed under similar temperature and humidity conditions, SR was significantly higher in the VS (p=0.002). There was no difference in D%, FIR, USG, and UC between control and VS (p>0.05). Strong correlation was observed between USG and UC (r = 0.76; p<0.001). It was concluded that the students performed adequate fluid replacement which provided a low degree of dehydration during training sessions and that the use of visual stimulus in only one session was not enough to significantly increase fluid intake during training sessions and in the recovery period

A falta de reposição hídrica adequada pode acarretar desidratação grave e fadiga precoce. O objetivo do estudo foi avaliar os efeitos do uso de estímulo visual sobre o estado de hidratação de mulheres praticantes de zumba fitness. Participaram do estudo 16 mulheres praticantes de zumba fitness (idade = 42,3 ± 12,0 anos, peso = 75,6±16,8 Kg, altura = 1,62 ± 0,58 m, IMC = 28,3 ± 4,6 Kg/m2, CC = 89,4 ± 10,1 cm, %GC = 38,0 ± 6,0). O estado de hidratação foi avaliado em três momentos: 1) familiarização, 2) treino habitual (Controle) e 3) treino com estímulo visual para hidratação (EV). Foram obtidos a massa corporal antes e após os treinos e o consumo de líquidos durante o treino. Foram calculadas a taxa de sudorese (TS), taxa de ingestão de líquidos (TIL) e porcentagem de desidratação (D%). A temperatura e umidade foram registradas durante os treinos. O estado de hidratação no período de recuperação foi avaliado por meio da gravidade específica da urina (GEU) e coloração da urina (UC) que foram medidos nas manhãs dos dias de treino e do dia seguinte ao treino. Apesar dos treinos terem sido realizados em condições de temperatura e umidade semelhantes, a TS foi significativamente maior no grupo EV (p=0,002). Não houve diferença na D%, TIL, GEU e UC entre controle e EV (p&gt;0,05). Foi observada forte correlação entre a GEU e UC (r = 0,76; p&lt;0,001). Conclui-se que as alunas realizaram reposição hídrica adequada o que proporcionou baixo grau de desidratação nos treinos e que a utilização de estímulo visual em apenas um treino não foi suficiente para aumentar significativamente a ingestão hídrica durante os treinos e no período de recuperação

The protein intake of trained bodybuilders is concentrated in lunch and dinner

Regular protein intake throughout the day can contribute to maximising protein synthesis and improve recovery and muscle mass gain. The objective of this study was to evaluate the dietary intake and the distribution of protein, carbohydrate, lipid and energy intakes of trained bodybuilders. Twelve men with experience in resistance training participated in the study. Body composition was determined by octapolar bioimpedance. Food intake was assessed using five 24-hour food recall schedules. The subjects presented the following characteristics: Age = 25.2 ± 3.4 years; Height = 179.5 ± 4.6 cm; Weight = 84.9 ± 8.7 kg; Body Fat = 14.7 ± 5.6% and Fat Free Mass = 85.3 ± 5.6%. The average time of weight training practice was 5.9 ± 3.1 years, with a weekly frequency of 5.0 ± 0.6 workouts and each session lasting an average of 64.2 ± 17.8 minutes. The average caloric intake was 2201 ± 223 kcal which represented 26.2 ± 6.0 kcal/kg. Only 33.3% of the individuals had adequate energy intake. The participants had a mean daily consumption of 1.6 ± 0.5 g/kg/day for proteins, 2.9 ± 0.8 g/kg/day for carbohydrates and 0.9 ± 0.4 g/kg/day for fat. The percentage of adequacy was 58.3%, 50%, and 91.7% for carbohydrates, proteins, and fat, respectively. Protein consumption was irregular throughout the day, being concentrated at lunch (52.2 ± 17.8 g) and dinner (40.2 ± 20.5 g). We conclude that the individuals consumed a diet with low energy content and irregular distribution throughout the day, especially of protein. Thus, the results indicate that the dietary intake of the volunteers can be improved expressively
