Brief summary
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
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Perception of effort during running. | 1 day | Perception of Borg scale rated effort (0 no effort; 10, maximal effort) while running on a treadmill at sub-maximum intensity |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Perception of effort depending on running distance | 18 months | Comparison of the perception of effort (Borg scale rated effort (0 no effort; 10, maximal effort) while running) between subjects according to the distance of running |
| Link between the individual's physical level and perception of effort | 18 months | Correlation between VO2max assessed during exercise testing in the laboratory and effort perception |
| Serological library | 18 months | Comparison of circulating markers (e.g. BDNF, s100, creatine kinase, interleukins, to be defined a posteriori according to the physiological and cerebral effects observed) before and after the race |
| Psychological profiles of trail-running practitioners | 18 months | Assessement of internal discourses use, pre-competitive anxiety, self-determined motivation to practice, achievement goals assessed by a questionnaire |
| Brain activation during a cognitive task | 3 months | Changes in brain oxygenation assessed by NIRS during a cognitive task |
| Perception of effort, attentional focus, self-efficacy and resources of self-control during a race situation | 1 day | Change in perception of effort, attentional focus, self-efficacy and self-monitoring resources, assessed by a questionnaire during the race |
| Recovery kinetics of runners after a trail race. | 2 weeks | Changes in the previous outcomes will be evaluated between the end of the race and 1-2 weeks after the race |
| Performance on a cognitive task | 3 months | Performance on a cognitive task performed on a computer |
