Revisión y análisis del ejercicio físico a nivel hormonal, cerebral y su influencia en el apetito / Review and analysis of physical exercise at hormonal and brain level, and its influence on appetite

Debido a los problemas de obesidad que hay en la actualidad, es importante llevar un buen control de la ingesta alimentaria. El propósito del presente estudio es conocer la influencia que tiene el ejercicio físico sobre el apetito, los cambios generados en las concentraciones de diferentes hormonas y la alteración de determinadas regiones cerebrales. Para ello se ha realizado una revisión bibliográfica a través de diferentes bases de datos. En cuanto a los resultados, se aprecia que el ejercicio produce cambios en el apetito, en la cantidad de ingesta de energía, en diferentes hormonas relacionadas con el control del peso así como en determinadas respuestas neuronales. Como conclusión, se puede afirmar que el ejercicio disminuye el apetito, el hambre y la ingesta de energía. Además, el ejercicio disminuye los niveles de grelina y aumenta las concentraciones de leptina. Asimismo, se muestra como el ejercicio físico altera la actividad de ciertas regiones del cerebro tras la visualización de determinados alimentos, con lo que disminuyen el apetito o la ingesta (AU)

Due to the currently growing rate of obesity, it is important to maintain good control of food intake. The main purpose of the present study is to determine the influence of physical exercise on appetite, changes in hormone concentrations, and changes in certain neuronal regions. To achieve this, a literature search was conducted using different data bases. The results show how exercise produces changes in the appetite perception, in the amount of energy intake, and in different weight-control related hormones, as well as in specific neuronal responses. In conclusion, it can be shown that exercise leads to changes in appetite, hunger, and energy intake. In addition, exercise decreases the ghrelin levels and increases concentrations of leptin. Likewise, it is shown how physical exercise alters the responses of certain neuronal regions after visualizing specific food elements decreasing so the appetite or the intake of them (AU)
