Outcomes
Primary Outcomes
Change From Baseline in the Time-Weighted Sum of Muscle Soreness With Movement Over 0-24 Hours Post-Dose 1 (MSM 0-24 )
Time Frame: Baseline, 0 to 24 hours post-Dose 1 on Day 1
Participants were asked to complete one preacher curl, using the arm that was exercised earlier to stimulate muscle soreness on movement (MSM). Upon completion of preacher curl, participants were asked to rate their degree of MSM, using an 11 point scale ranging from 0 to 10, where 0=not sore and 10=extremely sore, higher score=more severity. Change from baseline in the time-weighted sum of MSM over 0-24 hours was derived as the MSM change from baseline multiplied by time elapsed since the previous assessment and summed over all assessments from Hour 0 to Hour 24 (range: -96 to 240, higher score indicates better response).
