Determination of the effect of an intervention to develop the use of internal discourses on the perception of exercise during a sub-maximum effort following a trail running
The practice of mountain running or "trail" is in full development in France and elsewhere in the world. This sport practice is associated with various constraints specific to the activity.
These constraints imposed on the body during the preparation, participation and recovery of this type of effort have an impact on multiple aspects of the individual (physiological, psychological, neurological...). Some studies have made it possible in each of the fields to advance the current knowledge about the trail-running environment. However, there are very few links between variables from different fields of research, even though these links are at the origin of the complex individual responses observed in the field.
Therefore it seems important to study the practice of trail running and its consequences on the individual, relying on a systemic approach of the individual who studies how psychological phenomena, physiological and cerebral interactions to predict behaviour and its health consequences.
The biopsychosocial models are based on this systemic approach and postulate that the perception of the individual's effort would be the main limit to the continuity of effort, performance because it causes the intensity to decrease - or even stop the effort - if this sensation becomes too strong.
Consequently, the study of certain interventions aimed at reducing this perception of effort, such as the one proposed in this project, seems to be an essential step to propose to the practitioners of this type of sport strategies allowing to practice in a healthy and efficient way.
