"How Awareness and Subjectivity Modulate the Placebo Effect"

Sponsor: Fondazione Don Carlo Gnocchi Onlus

Summary

This study consists of a three-group experimental design (active placebo, passive placebo, control) with the primary outcome being perceived fatigue during a cycle ergometer training session. A pre-intervention assessment is planned, in which participants complete (online, via Qualtrics) the Borg Rating of Perceived Exertion (Borg CR10 Scale) and the Positive and Negative Affect Schedule (PANAS; scale for assessing positive and negative emotions). During the intervention, which consists of a cycle ergometer session with 10 minutes of warm-up and 10 minutes of more intense activity, participants will wear a heart rate monitor (Garmin HRM-Pro) to record heart rate and respiratory rate. In addition to these outcomes, distance traveled and speed achieved, extracted from the cycle ergometer data, will also be considered. At the end of the session, the pre-intervention assessment (Borg CR10 and PANAS) will be repeated, and a perceived control scale (Locus of Control of Behaviour) will also be administered.
