UNLABELLED Compared to soy, whey protein is higher in leucine, absorbed quicker and results in a more pronounced increase in muscle protein synthesis. OBJECTIVE To determine whether supplementation with whey promotes greater increases in muscle mass compared to soy or carbohydrate, we randomized non-resistance-trained men and women into groups who(More)
We evaluated the effects of grape polyphenols in individuals classified with metabolic syndrome (MetS). Men (n = 24) aged 30-70 y were randomly assigned to consume either a freeze-dried grape polyphenol powder (GRAPE) or a placebo for 30 d in a double-blind, crossover design, separated by a 3-wk washout period. Participants were asked to maintain their(More)
BACKGROUND A sedentary lifestyle is a major risk factor for cardiovascular and thrombotic complications. While habitual endurance activity will reduce the risk of these adverse events, the influence of habitual resistance exercise is less clear. This study examined coagulation and fibrinolytic responses to an acute exhaustive resistance exercise test(More)
no son comparables ni intercambiables. Body composition assessment by anthropometry and bioelectrical impedance Introduction. Anthropometry and electric impedance methods are widely used for body composition assessment. However the evidence is unclear whether the results obtained from the two methods can be compared. Objective. Two methods are compared for(More)
INTRODUCTION Anthropometry and electric impedance methods are widely used for body composition assessment. However the evidence is unclear whether the results obtained from the two methods can be compared. OBJECTIVE Two methods are compared for assessment of body composition; anthropometry and electric impedance. MATERIALS AND METHODS Body composition(More)
Recent connections between platelet activity and cardiovascular disease have raised questions of whether platelet function varies in exercising individuals. Resistance training has been linked to a possible reduction in hyper-aggregability of platelets, especially following acute strenuous exercise. The present investigation was designed to explore the(More)
BACKGROUND The world health organization (WHO) and the Identification and prevention of dietary- and lifestyle-induced health effects in children and infants- study (IDEFICS), released anthropometric reference values obtained from normal body weight children. This study examined the relationship between WHO [body mass index (BMI) and triceps- and(More)
Introducción. Las ecuaciones de pliegues cutáneos son ampliamente utilizadas para estimar la composición corporal; sin embargo, en nuestra población no se han validado contra un método de referencia. Objetivo. Validar por hidrodensitometría las ecuaciones de Durning/Womersley, Jackson/ Pollock y Ramírez/Torun en mujeres de 18 a 40 años. Materiales y(More)
Introduction. Skinfold thickness equations are widely used for body composition assessment. However the equations have not been validated in Colombia with a reference method. Objective. The skinfold thickness equations of Durning/Womersley, Jackson/Pollock and Ramírez/Torun were validated by hydrodensitometry in female from 18 to 40 years old. Materials and(More)
