In plain words

What the trial is, and whether it could suit you

This pilot randomized crossover study will evaluate the acute effects of immersive virtual reality (IVR) on respiratory effort during submaximal exercise in healthy adults. Dyspnea and increased respiratory effort are influenced not only by mechanical and metabolic factors, but also by emotional and central neural inputs. IVR has shown potential to reduce anxiety, promote relaxation, and modulate physiological responses, but its direct effect on respiratory effort has not been adequately studied. Healthy adults will complete two experimental exercise sessions: one session with IVR and one session without IVR, in randomized order. In both conditions, participants will perform a 6-minute constant-load cycling test at a submaximal workload individualized from a prior incremental exercise test. Respiratory effort will be assessed continuously using esophageal pressure monitoring. Additional
