Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This randomized controlled trial with healthy subjects aims to compare exercise-induced hypoalgesia among three groups: one utilizing a lower limb cycle ergometer, another using an upper limb cycle ergometer, and a control group. The exercise protocol involves 30 minutes of aerobic activity at 70-80% of the heart rate reserve. Exercise-induced hypoalgesia will be assessed by measuring pressure pain thresholds in the thigh and elbow. Additionally, a secondary objective is to compare the lower limb and upper limb cycle ergometer groups in terms of their effects on pressure pain thresholds in the thigh and elbow. Thus, the study anticipates observing differences in local and distal hypoalgesia based on the trained region.
