Why Running Helps Clear Your Mind -- Science of Us. It is something of a cliché among runners, how the activity never fails to clear your head. Does some creative block have you feeling stuck? Go for a run. Are you deliberating between one of two potentially life-altering decisions? Go for a run. Are you feeling mildly mad, sad, or even just vaguely meh? Go for a run, go for a run, go for a run. The author Joyce Carol Oates once wrote in a column for the New York Times that “in running the mind flees with the body … in rhythm with our feet and the swinging of our arms.” A good run can sometimes make you feel like a brand-new person.
The other fascinating thing here is where these new cells pop up: in the hippocampus, a region of the brain associated with learning and memory. Other post-run changes have been recorded in the brain’s frontal lobe, with increased activity seen in this region after people adopt a long-term habit of physical activity.

Background No systematic review has identified the incidence of running-related injuries per 1000 h of running in different types of runners. Objective The purpose of the present review was to systematically search the literature for the incidence of running-related injuries per 1000 h of running in different types of runners, and to include the data in meta-analyses. Data Sources A search of the PubMed, Scopus, SPORTDiscus, PEDro and Web of Science databases was conducted.
Study Selection Titles, abstracts, and full-text articles were screened by two blinded reviewers to identify prospective cohort studies and randomized controlled trials reporting the incidence of running-related injuries in novice runners, recreational runners, ultra-marathon runners, and track and field athletes. Study Appraisal and Synthesis Methods Data were extracted from all studies and comprised for further analysis. Results After screening 815 abstracts, 13 original articles were included in the main analysis. Influence of brain catecholamines on the development of fatigue in exercising rats in the heat - Hasegawa - 2008 - The Journal of Physiology. Abstract The purpose of the present study was to identify the effects of an acute injection of a dual dopamine (DA)/noradrenaline (NA) reuptake inhibitor (bupropion) on exercise performance, thermoregulation and neurotransmitters in the preoptic area and anterior hypothalamus (PO/AH) of the rat during exercise in the heat.
Body core temperature (Tcore), brain temperature (Tbrain) and tail skin temperature (Ttail) were measured. A microdialysis probe was inserted in the PO/AH, and samples for measurement of extracellular DA, NA and serotonin (5-HT) levels were collected. Rats received either bupropion (17 mg kg−1; hot-BUP) or saline (1 ml kg−1; hot) 20 min before the start of exercise and ran at a speed of 26 m min−1 until exhaustion in a warm environment (30°C). Rats also ran until exhaustion in a cool environment (18°C; cool). Provide feedback or get help You are viewing our new enhanced HTML article.

Foto luismimarlo.blogspot.com.esEn estas carreras, principalmente las ultras, es importante ser conscientes de la importancia de los avituallamientos con el objetivo de proporcionar hidratos de carbono y líquidos.
En estos sentidos siempre hemos hablado de evitar situaciones de deshidratación que pueden llegar a comportar riesgos de salud muy severos. Ahora bien, donde si hemos de incidir es en el riesgo de hiponatremia, situación en la que disminuye la cantidad de sodio en el plasma y por un trastorno de balance osmotico puede pasar agua al cerebro a través de la barrera hematoencefálica. La clínica puede ir desde alteraciones gastrointestinales, vómitos, fatiga inusual a trastornos neurológicos, con confusión desorientación y hasta coma. En corredores de fondo, lo más habitual, es que sea por la combinación del consumo excesivo de líquido y pérdida abundante de sal. Aspectos médicos a tener en cuenta en el corredor de montaña (I), por Daniel Brotons. El entrenamiento de montaña requiere unas exigencias fisiológicas y psicológicas realmente importantes, y nosotros los especialistas en medicina del deporte somos conscientes, por lo que interesa realizar un programa de seguimiento y control médico con el objetivo de preservar y potenciar la salud, prevenir patología y mejorar el rendimiento deportivo.
Interesa programar la temporada desde el punto de vista médico, y lo haremos en función del calendario de la temporada, para poder establecer las actuaciones médicas tanto en temas de salud como de rendimiento. Prueba de esfuerzo de Kilian Jornet. El vídeo se utilizó como adelanto de A Fine Line. He de destacar que en el comportamiento cardiovascular de esfuerzo observo muchas arritmias que requieren un protocolo de estudio, ya que en ocasiones forman parte de la propia función cardíaca sin observar ninguna alteración estructural y/o eléctrica que lo justifique. Vídeo explicativo del método de la Ecocardiografía. Exercise & The Brain. Thermoregulation, fatigue and brain neurotransmission during prolonged exercise in normal and high ambient temperatures. Fatigue should be acknowledged as a complex phenomenon influenced by both peripheral and central factors. Because strenuous exercise is associated with cerebral metabolic and neurohumoral alterations that may relate to central fatigue, it is important to explore the influence of neurotransmitters (specifically serotonine, dopamine and noradrenaline) on the outcome of performance and in particular on fatigue.
Prolonged exercise may induce homeostatic disturbances within the central nervous system that subsequently attenuates motor activation. Therefore, strenuous exercise is a challenge not only to the cardiorespiratory and locomotive systems but also to the brain. In a series of experiments we explored this so-called ‘central fatigue hypothesis’ by the acute administration of different reuptake inhibitors during a 90 min time trial. Probably central fatigue is not the result of changes in one neurotransmitter system, but rather a co-operation between different neurotransmitter systems. Central nervous system fatigue. Neurochemical Mechanisms[edit] While many neurochemical changes have been observed during central nervous system fatigue, no current experimental method can provide a direct causal link between the neurochemical changes and fatigue.
However, existing methods have provided enough evidence to suggest that serotonin and dopamine are significant drivers of central nervous system fatigue.[1] Serotonin[edit] Dopamine[edit] Dopamine is an excitatory neurotransmitter that regulates arousal, motivation, muscular coordination, and endurance performance.[4] Dopamine levels have been found to be lower after prolonged exercise.[5] A decrease in dopamine can decrease athletic performance as well as mental motivation. Acetylcholine[edit] Acetylcholine is required for the generation of muscular force. Manipulating Central Nervous System Fatigue[edit] Amphetamine[edit] Amphetamine is a stimulant that has been found to improve both physical and cognitive performance.

Lleva el control médico de Núria Picas, Bea García, Tòfol Castanyer, Kílian Jornet y un sinfín de corredores de montaña, por lo que su profundo conocimiento de esta disciplina deportiva está fuera de toda duda.

La conversación se lleva a cabo en una de las consultas en las el Dr. Brotons controla médicamente a los deportistas que pasan por sus manos. Dr. Los retos que se plantean los corredores de montaña deben ser coherentes con las posibilidades reales de conseguirlos. El Dr Brotons dice:Cuando nos ponemos a correr, las endorfinas fluyen y realizan su función, bloqueando muchas sensaciones negativas que en otras circunstancias interpretaríamos como un peligro para nuestra integridad.
