The aim of the present study was to examine the effects of green tea epigallocatechin-3-gallate (EGCG) on changes in body composition, energy and substrate metabolism, cardiometabolic risk factors and liver function enzymes after an energy-restricted diet intervention in obese women. In the present randomised, double-blind, placebo-controlled study,(More)
BACKGROUND Representative data for the Spanish population regarding physical activity (PA) behaviors are scarce and seldom comparable due to methodological inconsistencies. AIM Our objectives were to describe the PA behavior by means of the standardized self-reported International Physical Activity Questionnaire (IPAQ) and to know the proportion of the(More)
INTRODUCTION The anthropometric profile, specifically body composition, plays a crucial role in the physical performance of volleyballers. Since there are varying positions in volleyball, it is likely that differences exist in anthropometric and physical performance profiles among players due each role's specific physical requirements. OBJECTIVES The aims(More)
INTRODUCTION Volleyball practice requires repeated impacts on arms and feet caused by vertical jumps, falls, auctions, sudden and rapid changes of direction, which is why might raise us problems in the metabolism of iron (Fe) and the recommended intake of 18 mg/day (in the women in general), is not sufficient to meet the needs of the players of volleyball(More)
The objective measurement of human movement and the quantification of energy expenditure due to physical activity is an identified need in both research and the clinical setting. Validated and well-defined reference methods (double labelled water, direct calorimetry, indirect calorimetry) are expensive and mostly limited to the laboratory setting.(More)
BACKGROUND An increase of sedentary behaviors far from the Mediterranean lifestyle is happening in spite of the impact on health. The aims of this study were to describe sedentary behaviors in children and adolescents. METHODS A representative sample of 424 Spanish children and adolescents (38% females) involved in the ANIBES study was analyzed regarding(More)
BACKGROUND The relationship between cardiovascular disease and lipid profile is well known. Apart from a heart-healthy diet, exercise is the primary factor that can modify this lipid-associated cardiovascular risk. The aim of the study was to evaluate potential changes in the levels of triglycerides, total cholesterol (TC), low-density(More)
Continuous physical exercise leads the athlete to maintain an unstable balance between dietary intake, energy expenditure and the additional demands of a high amount of physical activity. Thus, an accurate assessment of nutritional status is essential to optimize the performance, since it affects health, body composition, and the recovery of the athlete.(More)
Basketball can be described as a moderate-to-long duration exercise including repeated bouts of high-intensity activity interspersed with periods of low to moderate active recovery or passive rest. A match is characterized by repeated explosive activities, such as sprints, jumps, shuffles and rapid changes in direction. In top-level modern basketball,(More)
BACKGROUND The current aims were to determine body composition (BC), and heart rate (HR) and rating of perceived effort (RPE) responses by female basketball referees during elite international competition. METHODS During the precompetition, BC via skinfolds was assessed in 10 referees (38±3 yr) who officiated 11 matches. Referees' HR and exercise(More)
