Abstract

The placebo effect has been defined as a genuine psychobiological response that arises from the belief that a positive intervention has been received. However, the notion that belief in an active treatment is necessary to elicit a placebo effect has been challenged. Recent data show that placebo effects may occur even when individuals are openly informed that they are receiving an inert treatment, the so-called open-label placebo. In fact, clinical studies have shown improvements in disease symptoms in patients who underwent an open-label placebo intervention. Now, the application of open-label placebo is attracting interest among the sports science community. Open-label placebo could be a useful and ethically permitted tool to improve exercise performance when applied in combination with other legal ergogenic aids (e.g., nutritional supplements) and/or in place of illegal substances (e.g., anabolic steroids). However, independent laboratories recently investigated the effects of open-label placebo on exercise performance with contrasting results, suggesting that there is much more research required before widespread implementation of open-label placebo in the field of sport and exercise can be justified. Herein we discuss the emerging science on open-label placebo interventions from a clinical setting to sports science. Moreover, we propose a research agenda for investigations on open-label placebo in sports and exercise sciences by covering the main gaps in the field. Addressing the research agenda put forward will help to advance our understanding of this intriguing topic. (AU)
