Insomnia and Sleep Disruption's Effect on Pain Sensitivity and Muscle Soreness After Exercise

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Researchers will examine how sleep condition relates to pain sensitivity and the course of muscle soreness after a standardized eccentric exercise in healthy adults. Participants will undergo a safe, reversible pain model and will be evaluated for how sleep quality and duration influence pain responses over time. The study uses a single observational design to explore associations between sleep variables and pain dynamics in the general population. Results may help clarify whether sleep impacts pain perception and recovery after muscle stress.
