ABSTRACT
La Gimnasia Rítmica es un deporte que exige habilidades motoras de alto nivel de dificultad y una perfecta ejecución. El yoga es considerado como una terapia de cuerpo y mente que para muchos investigadores influye en la mejora del rendimiento deportivo. En este trabajo analizamos el efecto de un entrenamiento de Yoga sobre del rendimiento deportivo y las variables psicológicas relacionadas con éste. Participaron 30 gimnastas entre 11 y 16 años que realizaron una sesión de Yoga semanal durante 5 meses, además del entrenamiento de Gimnasia Rítmica. Analizamos los cambios en el rendimiento y en las variables psicológicas estudiadas antes y después de la intervención. Los resultados obtenidos indican una mejora significativa de ambos parámetros. Conclusiones: las gimnastas participantes en nuestro estudio mejoran significativamente el rendimiento después de la intervención, lo que puede sugerir, sin poder generalizar, las ventajas de incluir programas de ejercicios de yoga en su preparación.

Rhythmic Gymnastics is a sport that requires high-difficulty motor skills and perfect execution. The body is considered as a yoga and mind therapy that for many researchers influences the improvement of sports performance. In this work we analyze the effect of a Yoga training on sports performance and the psychological variables related to it. Thirty gymnasts between the ages of 11 and 16 participated, doing a weekly Yoga session for 5 months, in addition to the Rhythmic Gymnastics training. We analyze the changes in performance and in the psychological variables studied before and after the intervention. The results obtained indicate a significant improvement in both parameters. Conclusions: the gymnasts participating in our study significantly improve their performance after the intervention, which may suggest, without generalizing, the advantages of including a yoga exercise program in their preparation.

Los objetivos del estudio fueron determinar la influencia de la morfología del pie en el rendimiento en Gimnasia Rítmica y analizar la influencia de los años de práctica. La muestra estaba compuesta por 48 gimnastas que habían practicado gimnasia federada y competido durante el último año. Los resultados indican que las gimnastas tienen predominantemente un pie neutro y con huella normal, presentando bastante asimetría entre pies, no significativa, lo que puede ser consecuencia de un trabajo unilateral y debería ser corregido en el entrenamiento. Sólo el rango de amplitud de la articulación talocrural parece ser una característica de la morfología del pie que incida sobre el rendimiento técnico y parece más una característica innata. La práctica de la Gimnasia Rítmica podría no ser un factor tan decisivo como podía suponerse en las modificaciones morfológicas de la huella plantar
The objectives of the study were to determine the influence of foot morphology on performance in Rhythmic Gymnastics and to analyze the influence of years of practice. The sample consisted of 48 gymnasts who had practiced federated gymnastics and competed during the last year. The results indicate that the gymnasts have predominantly a neutral foot and with a normal footprint, presenting enough asymmetry between feet, not significant, which may be a consequence of asymmetric work and should be corrected in training. Only the range of amplitude of the talocrural joint seems to be a characteristic of foot morphology that affects technical performance and seems more an innate characteristic. The practice of rhythmic gymnastics might not be as decisive a factor as could be supposed in the morphological modifications of the footprint

Inhaled amiloride has been recently demonstrated to have an effect on the decline of pulmonary function in patients with cystic fibrosis. Other diuretics have been demonstrated to provide protection against bronchoconstriction in asthmatic subjects. We report on the effect of inhaled amiloride on cold air hyperventilation challenge (CAHC) and methacholine challenge in asthmatics. We studied nine subjects with mild-moderate asthma in a double-blind, placebo-controlled, crossover study. Our results showed amiloride did not significantly protect against the bronchoconstriction induced by CAHC. Inhaled amiloride did not affect FEV1 in the hour after inhalation, and there was no significant difference between placebo or amiloride on the dose of methacholine causing a 20 percent fall in FEV1. Inhaled amiloride appears not to have a profile of action as previously seen with inhaled furosemide.

Methacholine inhalation challenge has become an accepted test to determine the presence of airway hyperresponsiveness, a hallmark of asthma. To help physicians interpret the results of a methacholine challenge test in a clinical setting, we analyzed the test data of 1,105 subjects, asthmatics and nonasthmatics. Applying Bayes' theorem, a nomogram was constructed incorporating the prechallenge clinical diagnosis with the response to methacholine to give a posttest probability of the diagnosis of asthma. The resulting curves represent different levels of cumulative breath units at which a methacholine challenge can be considered positive. The results of a methacholine challenge test, in association with a physician's clinical assessment, can be a valuable tool in the diagnosis of asthma in those patients with an atypical history and/or physical examination.
