U.S., Dec. 19 -- ClinicalTrials.gov registry received information related to the study (NCT07290465) titled 'Pain Perception and Exercise-Induced Hypoalgesia Across Circadian Rhythms' on Nov. 14.

Brief Summary: The goal of this randomized crossover clinical trial is to investigate whether exercise-induced hypoalgesia (EIH) is influenced by circadian rhythm in healthy adults aged 18-40 years.

The main questions it aims to answer are:

* Does the time of day (morning vs. evening) influence changes in pain perception following exercise?

* Do chronotype, sex, or stimulation site (bony vs. muscular) alter the magnitude of this effect?

Participants will:

* Complete questionnaires

* Undergo quantitative sensory testing

* Attend both morning...
