          Abstract

          Resumen El ejercicio aeróbico y de resistencia se ha relacionado con la promoción de la salud física, además en los últimos años se han investigado sus beneficios a nivel cognitivo. En base a ello, el objetivo de este trabajo fue evaluar el posible efecto de tener un estilo de vida activo sobre la memoria emocional. Participaron del estudio 48 adultos de edad temprana y media (rango: 18-58 años) que llevaron a cabo un auto-reporte mediante el Cuestionario Internacional de Actividad Física dando cuenta de la cantidad y tipo de actividad física realizada en una semana habitual o típica, es decir aquella sostenida durante los últimos tres meses de sus vidas. Para evaluar la memoria emocional los participantes observaron una serie de imágenes positivas, negativas y neutras seleccionadas del Sistema Internacional de Imágenes Afectivas. Luego se evaluó cuántas imágenes recordaban y reconocían (tanto de modo inmediato como diferido). Se halló que los sujetos que poseían un nivel alto de actividad física en su vida diaria recordaban inmediatamente más estímulos de valencia positiva que aquellos con niveles moderados y bajos. Además, este grupo obtuvo mejores resultados en la evaluación de reconocimiento inmediato. Por tanto, incorporar a la actividad física y deportiva como un estilo de vida, mostraría tener efectos favorables en la memoria de estímulos visuales vinculados a emociones positivas.

          Abstract Aerobic and resistance exercise has been related to physical health promotion, besides in the last years its effects at a cognitive level has been investigated. Based on that, the aim of the current work was to evaluate the possible effect of having an active life style on emotional memory. Fortyeight adults of early and middle age participated (range: 18-58 years old) who complete a report through the International Physical Activity Questionnaire about the amount and type of physical activity performed in a typical or regular week, i.e. a week sustained in the last three months of their lives. To evaluate emotional memory participants watched positive, negative and neutral images selected from the International Affective Picture System. Then, how many images they recall and recognize was evaluated (immediate and deferred measures). Participants that had a high level of physical activity in their lives remember immediately more positive images than those participants with a low or moderate level of activity. Besides, this group obtained better results in the immediate recognition measure. Thus, incorporate physical activity as a life style shows benefits in the emotional positive memory.

          Episodic memory: from mind to brain.

          Episodic memory is a neurocognitive (brain/mind) system, uniquely different from other memory systems, that enables human beings to remember past experiences. The notion of episodic memory was first proposed some 30 years ago. At that time it was defined in terms of materials and tasks. It was subsequently refined and elaborated in terms of ideas such as self, subjective time, and autonoetic consciousness. This chapter provides a brief history of the concept of episodic memory, describes how it has changed (indeed greatly changed) since its inception, considers criticisms of it, and then discusses supporting evidence provided by (a) neuropsychological studies of patterns of memory impairment caused by brain damage, and (b) functional neuroimaging studies of patterns of brain activity of normal subjects engaged in various memory tasks. I also suggest that episodic memory is a true, even if as yet generally unappreciated, marvel of nature.

            Exercise training increases size of hippocampus and improves memory.

            The hippocampus shrinks in late adulthood, leading to impaired memory and increased risk for dementia. Hippocampal and medial temporal lobe volumes are larger in higher-fit adults, and physical activity training increases hippocampal perfusion, but the extent to which aerobic exercise training can modify hippocampal volume in late adulthood remains unknown. Here we show, in a randomized controlled trial with 120 older adults, that aerobic exercise training increases the size of the anterior hippocampus, leading to improvements in spatial memory. Exercise training increased hippocampal volume by 2%, effectively reversing age-related loss in volume by 1 to 2 y. We also demonstrate that increased hippocampal volume is associated with greater serum levels of BDNF, a mediator of neurogenesis in the dentate gyrus. Hippocampal volume declined in the control group, but higher preintervention fitness partially attenuated the decline, suggesting that fitness protects against volume loss. Caudate nucleus and thalamus volumes were unaffected by the intervention. These theoretically important findings indicate that aerobic exercise training is effective at reversing hippocampal volume loss in late adulthood, which is accompanied by improved memory function.

              Aerobic fitness is associated with hippocampal volume in elderly humans.

              Deterioration of the hippocampus occurs in elderly individuals with and without dementia, yet individual variation exists in the degree and rate of hippocampal decay. Determining the factors that influence individual variation in the magnitude and rate of hippocampal decay may help promote lifestyle changes that prevent such deterioration from taking place. Aerobic fitness and exercise are effective at preventing cortical decay and cognitive impairment in older adults and epidemiological studies suggest that physical activity can reduce the risk for developing dementia. However, the relationship between aerobic fitness and hippocampal volume in elderly humans is unknown. In this study, we investigated whether individuals with higher levels of aerobic fitness displayed greater volume of the hippocampus and better spatial memory performance than individuals with lower fitness levels. Furthermore, in exploratory analyses, we assessed whether hippocampal volume mediated the relationship between fitness and spatial memory. Using a region-of-interest analysis on magnetic resonance images in 165 nondemented older adults, we found a triple association such that higher fitness levels were associated with larger left and right hippocampi after controlling for age, sex, and years of education, and larger hippocampi and higher fitness levels were correlated with better spatial memory performance. Furthermore, we demonstrated that hippocampal volume partially mediated the relationship between higher fitness levels and enhanced spatial memory. Our results clearly indicate that higher levels of aerobic fitness are associated with increased hippocampal volume in older humans, which translates to better memory function.
