RESUMO
The purpose of this study was to determine the foot strike pattern (FSP), inversion (INV) and spatial-temporal variables in a large sample of recreational runners during a long-distance competition, according to sex and changes in the classification race. A total of 368 men and 67 women, who participated in the XVII International Half Marathon of Cordoba (Spain) were analysed. It was recorded at km 5 and km 15, where high-speed camcorder and 2D-photogrammetric techniques were used to measure FSP, INV, contact time (CT) and flight time (FT). The group that worsened their classification at km 15 increase RFS prevalence and INV asymmetry. A Pearson analysis indicates that variation of the classification in the race between the marks km 5 and km 15 is related with CT (r=0.429, p<0.001) and FT (r=-0.360, p<0.001). RFS prevalence and spatial-temporal parameters showed different patterns depending on whether the runners improved or worsened their ranking. (AU)
El objetivo de este estudio fue determinar el patrón de pisada, inversión y variables espaciotemporales para una amplia muestra de corredores amateurs, durante una carrera de larga distancia, según sexo y posición de clasificación. Se analizaron 368 hombres y 67 mujeres, que participaron en la XVII Media Maratón Internacional de Córdoba (España). Se registró el km 5 y km 15, utilizando técnicas de fotogrametría 2D de alta velocidad para medir la pisada, la inversión, el tiempo de contacto (TC) y el tiempo de vuelo (TV). El grupo que empeoró su clasificación en el km 15 aumentó la prevalencia de FSP y la asimetría del INV. Un análisis de Pearson indica que la variación de la clasificación en la carrera está relacionada con TC (r=0,429, p<0,001) y TV (r=-0,360, p<0,001). La prevalencia de retropié y los parámetros espaciotemporales mostraron diferentes patrones dependiendo de si los corredores mejoraron o empeoraron su clasificación. (AU)

El objetivo de este estudio fue conocer la asociación entre el entrenamiento de atletas con las características de cada pie. Se midieron y compararon las huellas plantares de tres grupos de deportistas (28 velocistas, 29 fondistas, 47 nadadores) y de 67 sujetos no entrenados (GC). Para la captura de parámetros plantares se empleó una plataforma de escaneado podálico Podoscanalycer®. El índice podálico, metatarsal, medio podálico, y calcáneo fue inferior en GC respecto a corredores de velocidad, fondo, y nadadores (p<0.001). El riesgo relativo de tener un pie cavo o un tipo de pié específico por pertenecer a una determinada modalidad atlética no resulto significativo (todos p>0.05). Se concluye que los años de entrenamiento y la edad en atletas españoles no se asocian significativamente con la curvatura y tipología del pie ni sobre ningún índice plantar específico. Sin embargo, sexo e IMC se asocia significativamente con los índices plantares según la modalidad atlética (AU)
The aim of the present study was to determine the association between athletic training and characteristics of each foot. Plantar foot print of three groups of athletes (28 sprinters, 29 distance runners, 47 swimmers) and 67 sedentary subjects (CG) were measured and compared. A scanning platform breech Podoscanalyzer was employed to obtain plantar pressure measurements. The breech, metatarsal, middle breech, and calcaneus index, were lower in CG compared to sprinters, long-distance runners, and swimmers (p<0.001). The relative risk of having a cavus foot or any specific type of foot as a result of practicing a particular athletic discipline was not significant (all p>0.05). We conclude that the years of training and the age are not significantly associated neither with the curvature and the type of the foot nor with any specific plantar arch index in Spanish athletes. Nevertheless, sex and BMI are significantly associated with the plantar arch indexes according to the athletic discipline (AU)

The aim of this study was to determine the influence of barefoot running on foot-strike patterns, eversion-inversion, running speed and vertical foot rotation in endurance runners. Eighty healthy recreational runners (age = 34.11 ± 12.95 years old, body mass index = 22.56 ± 2.65 kg · m(-2)) performed trials in shod/unshod running conditions on a treadmill at comfortable and competitive self-selected speeds. Data were collected by systematic observation of lateral and back recordings at 240 Hz. McNemar's test indicated significant differences between shod/unshod conditions and foot strike at comfortable and competitive speeds (P < 0.001). Speed was related to vertical foot rotation type for shod (P < 0.01) and unshod conditions (P < 0.05). Significant differences were found between shod/unshod conditions in foot rotation at comfortable running speeds (P < 0.001) and competitive running speeds (P < 0.01). No significant difference was found in inversion or eversion (P ≥ 0.05). In conclusion, the results suggest that running kinematics, in terms of foot-strike patterns and vertical foot rotation, differ between shod/unshod conditions, while the inversion or eversion degree remains unchanged.

La asociación entre la deficiencia de vitamina D y un mayor riesgo de diversas enfermedades, entre ellas cardiovasculares y autoinmunes, ha aumentado en los últimos años el uso de suplementos para la normalización de los valores plasmáticos de esta vitamina. Desde entonces se ha descrito un mayor número de casos de intoxicación iatrogénica por vitamina D. Presentamos una enferma de 81 años con encefalopatía metabólica e insuficiencia renal secundarias a una intoxicación por vitamina D. Los suplementos orales con calcio y vitamina D se le prescribieron después de sufrir una fractura vertebral osteoporótica. La enferma mejoró clínica y analíticamente tras hidratación y diuréticos. Es importante destacar la hipercalcemia como causa de encefalopatía metabólica y considerar la intoxicación por vitamina D como etiología poco frecuente pero posible de hipercalcemia e insuficiencia renal reversibles (AU)
The association between vitamin D deficiency and increased risk of, among others, cardiovascular and autoimmune diseases has lead in the last years to an enhanced interest in the usage of supplements to achieve the normalization of plasmatic values at 25(OH) D. Apparently this search for normalization is resulting in an higher incidence on vitamin D intoxication. We present the case of an 81 years old woman with metabolic encephalopathy and renal failure secondary to iatrogenic vitamin D intoxication. Calcium and vitamin D oral supplements were prescribed after an osteoporotic vertebral fracture. The patient improved clinically as well as analytically after receiving treatment with diuretics and hydration. We emphasize the importance of discarding hypercalcemia as a cause of metabolic encephalopathy; moreover we highly recommend keeping vitamin D intoxication in mind as an uncommon although always possible etiology of reversible hypercalcemia and renal failure (AU)

UNLABELLED: The purpose of this study is to analyzebody satisfaction in non-institutionalized old people and its association with sex, body mass index (BMI) and gait speed. METHODS: Hundred six people have participated, 38 men (age=74.60 ±6.67 years old) and 68 women (age=72.76 ±4.68 years old). The Body Shape Questionnaire (BSQ) has been used together with body composition and a gait speed test. RESULTS: Prevalence of body dissatisfaction in old people is about 5.6 %. Women have higher body fat percentage and less muscle mass. Significant differences were not found (p≥0.05) in the BSQ relating with sex. Obese old people with less gait speed showed higher score in BSQ. The Total BSQ is positively correlated with BMI (r=0.487, p<0.01), fat percentage (r=0.371, p<0.01) and negatively correlated with gait speed (r=-0.215 p<0.05)and perceived health status (r=-0.269, p<0.05). CONCLUSION: Older people's body satisfaction is positively associated with the perception of health and gait speed and negatively with BMI.
El objetivo de este estudio es analizar la satisfacción corporal en personas mayores no institucionalizados y su asociación con el sexo, el índice de masa corporal (IMC) y la velocidad de la marcha. Métodos: Ciento seis personas participaron en el estudio, 38 hombres (edad =74.60 ±6.67 años) y 68 mujeres (edad =72.76 ±4.68 años). Se empleó el Cuestionario de forma física (CFF) junto con un test de la composición corporal y la velocidad de la marcha. Resultados: La prevalencia de insatisfacción corporal en ancianos se sitúa entorno al 5.6 %. Las mujeres tienen un mayor porcentaje de masa corporal y menos masa muscular. No se encontraron diferencias significativas (p≥0.05) en el CFF en relación al sexo. Los ancianos obesos con menor velocidad de la marcha mostraron un resultado superior en el CFF. El total del CFF está positivamente relacionado con el IMC (r=0.487, p.
