The use of dietary complements like vitamins, minerals, trace elements, proteins, aminoacids and plant-derived agents is prevalent in the general population, in order to promote health and treat diseases. Dietary complements are considered as safe natural products and are easily available without prescription. However, these can lead to severe renal toxicity, especially in cases of unknown pre-existing chronic kidney disease (CKD). In particular, Chinese herbs including aristolochic acid, high doses of vitamine C, creatine and protein complements may lead to acute and chronic renal failure, sometimes irreversible. Dietary complement toxicity should be suspected in any case of unexplained renal impairement. In the case of pre-existing CKD, the use of potentially nephrotoxic dietary complements should be screened for.

Although the anthropometric profiles of Olympic athletes, as a group, are well known, there is still a need for specific reference data for each sport given that each discipline has its own characteristics. This study has been designed considering the limited number of articles that focus on the anthropometric characteristics of artistic roller skating and, more specifically, the figures discipline. The aim of this study is twofold: firstly, to define the anthropometric profile, body composition and somatotype of male and female artistic roller figure skaters in order to establish specific profiles; and, secondly, to establish the differences between the anthropometric profiles, body compositions and somatotypes of male and female skaters. Twenty-nine professional roller skaters (male = 15, female = 14) underwent measurements of standard anthropometry (height, body mass, arm span, 8 skinfolds, 3 breadths and 11 girths). The somatotype was measured using the Heath-Carter methods. A T-Student test for independent samples was conducted in order to assess the differences between male and female skaters. Significant statistical differences were found between male and female skaters in terms of body mass, height, arm span, the sum of four and six skinfolds and all skinfold measurements. Male skaters have a BMI of 21.4± 1.6 and female skaters have a BMI of 21.5 ± 2.4. The results indicate that arm span is an important characteristic for skaters. Mesomorphy is the most important component, followed by endomorphy, for male and female skaters. Male skaters have an endomesomorphic somatotype (3.5-4.5-2.5) and female skaters have a balanced mesomorphic somatotype (3.3-4.1-2.9).

Introducción: El baloncesto presenta una gran heterogeneidad antropométrica entre jugadores en relación a la posición de juego. El base suele ser el más bajo del equipo pero también el más rápido. El escolta suele ser similar al base, más bajo, rápido y ágil que el resto. El alero es de una altura intermedia entre los jugadores interiores y exteriores, combina la altura con la velocidad, y el pívot tiene un rol más físico, es el más alto y con mayor masa muscular. El objetivo del estudio es describir el perfil cineantropométrico del equipo cadete masculino del Valencia Basket Club. Material y Métodos: Se han evaluado 20 jugadores de baloncesto cadete masculino (15,35±0,59años). Un antropometrista nivel I tomó las medidas según la metodología de la Society for the Advancement of Kinanthropometry (ISAK). Se calculó la composición corporal según el consenso de cineantropometría del Grupo Español de Cineantropometría (GREC), el somatotipo según Heath-Carter, e índices adiposo-musculares. Resultados: Se observaron diferencias en los valores de peso, talla, pliegues cutáneos y composición corporal, de las variables estudiadas de la muestra total y por posición de juego, siendo los valores menores los de la posición base y mayores en los pívots. Se estableció una tendencia creciente de estos parámetros en el siguiente orden: base, escolta, alero y pívot. Conclusiones: El somatotipo global del jugador de baloncesto cadete del Valencia Basket Club es ectomorfo balanceado. Conocer el perfil cineantropométrico puede beneficiar la elaboración de planes de entrenamiento y nutrición, así como reflejar la evolución y dirigirla hacia las características ligadas al rendimiento óptimo.

Some physical characteristics are related to maximum sport performance, which has resulted in what has been denominated the morphological prototype.  Knowing about this concept is of great relevance for physical activity professionals.  Consequently, the purpose of this research was to give evidence as to whether the somatotypes of elite Cuban paddlers are related to international studies done in Spain (Esparza, 1993), Canada (Carter, 1999), Australia (Ackland et al, 2000), Argentina (Lentini et al, 2002), and the United States (Vaccaro et al, 2000).  A total of 30 athletes were evaluated including 9 female kayakers and 21 male canoeists and kayakers. This study shows the significant heterogeneity found in this population based on the behavior of the somatotypes when contrasting the groups.  Compared to the other reference studies, the endomorphic component proved to be the differentiating factor in this research.  The foregoing allowed us to conclude that actions should be taken to modify this component in a way that Cuban athletes are closer to the anthropometric profile exhibited by international elite teams.
