ABSTRACT
El mindfulness es una práctica meditativa que ha probado disminuir el estrés psicofisiológico. Propósito: analizar, si el mindfulness es efectivo para disminuir el estrés psicofisiológico, en deportistas de alto rendimiento en temporada competitiva. Se realizó una búsqueda de estudios clínicos que incluyeran diferentes técnicas meditativas para la reducción del estrés en deportistas durante la fase competitiva. En PubMed, Scopus y Web of Science (1985 al 10 de agosto del 2019), se buscaron las combinaciones de palabras mindfulness, meditation, yoga, sport, athlete, intervention, stress, cortisol. Se localizaron sólo siete trabajos, tres de ellos con información cuantitativa, un cuantitativo y tres de metodología mixta. En los siete estudios encontrados (153 sujetos; 134 hombres y 19 mujeres) sus autores mencionan que el mindfulness fue efectivo para la reducción del estrés en los atletas durante la etapa competitiva.
Mindfulness is a meditative practice that has proven to reduce psycho-physiological stress. Purpose: Analyze if mindfulness is effective to reduce psycho-physiological stress in athletes during their competitive season. Clinical studies that included different meditative techniques for stress reduction in athletes during the competitive phase was searched for in databases such as PubMed, Scopus and Web of Science (1985 to August 10, 2019), using the combinations of the words mindfulness, meditation, yoga, sport, athlete, intervention, stress, and cortisol. Only seven papers were located, three of them with a quantitative design, one as quantitative and three with mixed methodology. In the seven studies found (153 subjects; 134 men and 19 women) their authors mention that mindfulness was effective for reducing stress in athletes during the competitive season.

BACKGROUND: Exercise in the heat causes important water and electrolytes losses through perspiration. Optimal rehydration is crucial to facilitate the recuperation process after exercise. The aim of our study was to examine whether a moderate beer intake as part of the rehydration has any negative effect protocol after a short but dehydrating bout of exercise in the heat. METHODS: Sixteen active male (VO2max, 56 ± 4 mL/kg/min), were included in a crossover study and performed a dehydrating exercise (≤1 h running, 60 %VO2max) twice and 3 weeks apart, in a hot laboratory setting (35 ± 1 °C, humidity 60 ± 2 %). During the two hours following the exercise bouts participants consumed either mineral water ad-libitum (W) or up to 660 ml regular beer followed by water ad-libitum (BW). Body composition, hematological and serum parameters, fluid balance and urine excretion were assessed before, after exercise and after rehydration. RESULTS: Body mass (BM) decreased (both ~ 2.4%) after exercise in both trials. After rehydration, BM and fat free mass significantly increased although BM did not return to baseline levels (BM, 72.6 ± 6.7 to 73.6 ± 6.9; fat free mass, 56.9 ± 4.7 to 57.5 ± 4.5, no differences BW vs W). Beer intake did not adversely affect any measured parameter. Fluid balance and urine excretion values did not differ between the rehydration strategies. CONCLUSIONS: After exercise and subsequent water losses, a moderate beer (regular) intake has no deleterious effects on markers of hydration in active individuals.
