Iliopsoas and gluteal muscles are asymmetric in tennis players but not in soccer players

[EN] PURPOSE: To determine the volume and degree of asymmetry of iliopsoas (IL) and gluteal muscles (GL) in tennis and soccer players. METHODS: IL and GL volumes were determined using magnetic resonance imaging (MRI) in male professional tennis (TP) and soccer players (SP), and in non-active control subjects (CG) (n = 8, 15 and 6, respectively). RESULTS: The dominant and non-dominant IL were hypertrophied in TP (24 and 36%, respectively, P<0.05) and SP (32 and 35%, respectively, P<0.05). In TP the asymmetric hypertrophy of IL (13% greater volume in the non-dominant than in the dominant IL, P<0.01) reversed the side-to-side relationship observed in CG (4% greater volume in the dominant than in the contralateral IL, P<0.01), whilst soccer players had similar volumes in both sides (P = 0.87). The degree of side-to-side asymmetry decreased linearly from the first lumbar disc to the pubic symphysis in TP (r = -0.97, P<0.001), SP (r = -0.85, P<0.01) and CG (r = -0.76, P<0.05). The slope of the relationship was lower in SP due to a greater hypertrophy of the proximal segments of the dominant IL. Soccer and CG had similar GL volumes in both sides (P = 0.11 and P = 0.19, for the dominant and contralateral GL, respectively). GL was asymmetrically hypertrophied in TP. The non-dominant GL volume was 20% greater in TP than in CG (P<0.05), whilst TP and CG had similar dominant GL volumes (P = 0.14). CONCLUSIONS: Tennis elicits an asymmetric hypertrophy of IL and reverses the normal dominant-to-non-dominant balance observed in non-active controls, while soccer is associated to a symmetric hypertrophy of IL. Gluteal muscles are asymmetrically hypertrophied in TP, while SP display a similar size to that observed in controls. It remains to be determined whether the different patterns of IL and GL hypertrophy may influence the risk of injury.

Insurrectos cubanos deportados hacia Canarias y Fernando Poo (1869): un ejemplo de deportación política

[ES] Aproximación a la deportación política: causas, circunstancias que la rodean y caracterización del fenómeno, para ello nos centramos en un proceso concreto: la deportación de insurrectos cubanos en 1869 con dirección a Fernando Póo y que afecta directamente a las Islas Canarias, lugar utilizado tradicionalmente como destierro. En este sentido, intentamos acercarnos a las controversias y reacciones que genera el fenómeno de la deportación, en la población, en general así como en los grupos de poder político de las islas, en particular.

Sobre Fernando Estévez y algunas esculturas del Niño Jesús. Nuevas atribuciones

[ES] La conmemoración del ccxxv aniversario del nacimiento de Fernando Estévez (1788-1854) en 2013 propició una aproximación diferente a la trayectoria de dicho artista. Este artículo recuerda las actividades organizadas entonces en La Orotava, especialmente una exposición de esculturas y documentos que tuvo varias sedes o lugares de exhibición durante el mes de marzo. Partiendo de obras contempladas entonces, se estudian otras representaciones del Niño Jesús que conservan templos del norte de Tenerife y pueden atribuírsele por cuestiones de estilo. [EN] The commemoration of 225th birth anniversary of Fernando Estévez (1788-1854) in 2013 allowed a new approach to his artistic caree. This paper recalls the activities organised in La Orotava back then, especially an exhibition of sculptures and documents in several spaces during the month of March. Based on the sculptures seen there, we can attribute to him other representations of the Infant Jesus that are preserved in churches in northern Tenerife.
