An interventional study of Trail running of 28km and 2580m vertical drop in Running, Motivation for Physical Activity and Sport Physiology, sponsored by Centre Hospitalier Universitaire de la Réunion. Completed at 1 site in Reunion. Open to participants aged 18 Months and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-21.

The determinants of trail performance have been extensively studied, and the results have revealed the significant influence of physiological, psychological and biomechanical parameters.
Although there are numerous publications on the physiological responses of thermoregulation to exercise, the impact of heat and humidity on emotional regulation has never been studied in trail running. To the litterature, no study has looked at the evolution of biomechanical parameters during alternating ascents and descents in trail running.
No study has compared patterns of motivation between men and women during exercise, even though the hypothesis of a higher level of 'mental fitness' is put forward to explain the very high level of performance of women in long-distance events.
Centre Hospitalier Universitaire de la Réunion is the lead sponsor of 141 studies on the registry; 37 are open to participants now.

Effort measurements
Level of effort will be measured using a scale (Borg, 1990) from 0 to 10 (0 meaning no effort, and 10 maximal effort).
Time frame: 11 measurements, before the start and after each ascent and each descent, between 30 minutes and 1hour and 30 minutes
Pleasure measurements
Level of pleasure will be measured using a scale (Baron et al, 2011), from 0 to 10 (0 meaning no pleasure, and 10 maximal pleasure).
Time frame: 11 measurements, before the start and after each ascent and each descent, between 30 minutes and 1hour and 30 minutes
Sensation measurements
Levels of sensation will be measured using a scale (Hardy \& Rejeski, 1989) from -5 to +5 (-5 feeling very bad; to +5 feeling very good)
Time frame: 11 measurements, before the start and after each ascent and each descent, between 30 minutes and 1hour and 30 minutes
Fatigue measurements
Levels of fatigue will be measured using a scale (Brownstein et al, 2021) from 0 to 10 (0 not tired at all; to 10 total exhaustion)
Time frame: 11 measurements, before the start and after each ascent and each descent, between 30 minutes and 1hour and 30minutes
Motivation measurements
Levels of motivation (5 questions) will be measured using a scale MMSE (Baron et al, 2022) from 0 to 7 (0 not motivation to 7 very motivated)
Time frame: 11 measurements, before the start and after each ascent and each descent, between 30 minutes and 1hour and 30 minutes
