Participants will attend three sessions. Participants will fill out questionnaires, undergo pain sensitivity testing, and be randomly assigned to complete a high and low fatigue exercise on either the second or third session. During the exercise, participants will complete three sets of a single leg knee extension exercise with weight equivalent to 50% of their 1 repetition maximum until they report either a high or low fatigue level. Immediately before and after each set, the research team will examine immediate changes in sensitivity to pressure (pressure pain threshold).
The primary purpose of this study is to compare immediate changes in pain sensitivity (pressure pain threshold) during quiet rest, low fatigue exercise, and high fatigue exercise.
