Exercise Induced Hypoalgesia After 45-Degree Roman Chair Exercise

This is a study to examine pain sensitivity, before and after a back extension performed on a 45 degree roman chair. You will attend two testing sessions, each testing session will be approximately one hour. During session one you will be briefly exposed to heat and pressure to examine your pain sensitivity, complete a demographic questionnaire, and measure the strength of your low back before and after the exercise. You will also have heat and pressure pain sensitivity performed before and after a period of quiet rest and a back extension exercise on a 45 degree roman chair. During session two you will have the strength of your low back measured before and after the exercise, and heat and pressure sensitivity measured before and after a period of quiet rest and the back extension exercise.
