Primary Outcome Measures

Name	Time	Method
Change From Baseline in the Time-Weighted Sum of Muscle Soreness With Movement Over 0-24 Hours Post-Dose 1 (MSM 0-24 )	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).

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in the Time-weighted Sum of Spontaneous Muscle Soreness Over 0-24 Hours, 24-48 Hours, 48-72 Hours, and 0-72 Hours Post-Dose 1	Baseline, 24 to 48, 48 to 72, 0 to 72 hours post-Dose 1 on Day 1	Participants after sitting quietly for 3 minutes, were asked to extend the arm that was exercised earlier to stimulate MSM. Participants were asked to rate their degree of SMS, 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 time-weighted sum of SMS over 0-24 hours (hr.), 24-48 hr., 48-72 hr. and 0-72 hr. were derived as the SMS change from baseline multiplied by time elapsed since the previous assessment and summed overall assessment from Hour 0 to Hour 24 (range: -240 to 240, higher score indicates better response), Hour 24 to Hour 48 (range: -240 to 240, higher score indicates better response); Hour 48 to Hour 72 (range: -240 to 240, higher score indicates better response); and Hour 0 to Hour 72 (range: -720 to 720, higher score indicates better response).
Change From Baseline in Spontaneous Muscle Soreness at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 24, 30, 36, 48, 54, 60 and 72 Hours Post-Dose 1	Baseline,1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 24, 30, 36, 48, 54, 60 and 72 hours post-Dose 1 on Day 1	Participants after sitting quietly for 3 minutes, were asked to extend the arm that was exercised earlier to stimulate SMS. Participants were asked to rate their degree of SMS, using an 11-point scale ranging from 0 to 10, where 0=not sore and 10=extremely sore, higher score=more severity.
Time-weighted Sum of Muscle Soreness Relief Over 0-24 Hours, 24-48 Hours, 48-72 Hours, and 0-72 Hours	0 to 24, 24 to 48, 48 to 72 and 0 to 72 hours on Day 1	Participants were asked: "Which phrase best describes the relief of muscle soreness which you are experiencing?" Participant's response were recorded using a five-point scale: 0=None, 1=A little, 2=Some, 3=A lot and 4=Complete relief. Time-weighted sum of muscle soreness relief over 0-24 hours, 24-48 hours, 48-72 hours, and 0-72 hours were derived as the muscle soreness relief score multiplied by time elapsed since the previous assessment and summed over all assessments from Hour 0 to Hour 24 (total score range: 0 \[none\] to 96 \[complete relief\], higher score indicates better response), Hour 24 to Hour 48 (range: 0 to 96, higher score indicates better response); Hour 48 to Hour 72 (range: 0 to 96, higher score indicates better response); and Hour 0 to Hour 72 (range: 0 to 288, higher score indicates better response).
Change From Baseline in Stiffness During Muscle Soreness With Movement (SMSM) Assessment at 24 Hours Post-Dose 1	Baseline, 24 hours post-Dose 1	Participants were asked to rate their SMSM, using an 11-point scale, with 0=not stiff and 10=extremely stiff, higher score indicated more severity.
Change From Baseline in the Time-Weighted Sum of Muscle Soreness With Movement Over 24-48 Hours, 48-72 Hours, 0-72 Hours Post-Dose 1	Baseline, 24 to 48, 48 to 72, 0 to 72 hours post-Dose 1 on Day 1	Participants were asked to complete one preacher curl, using the arm that was exercised earlier to stimulate 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 scores=more severity. Change from baseline in the time-weighted sum of MSM over 24-48 hours, 48-72 hours and 0-72 hours were derived as the MSM change from baseline multiplied by time elapsed since the previous assessment and summed over all assessments from Hour 24 to Hour 48 (range: -96 to 240, higher score indicates better response); Hour 48 to Hour 72 (range: -96 to 240, higher score indicates better outcome); and Hour 0 to Hour 72 (range: -288 to 720, higher score indicates better response).
Change From Baseline in Muscle Soreness With Movement at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 24, 30, 36, 48, 54, 60 and 72 Hours Post-Dose 1	Baseline,1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 24, 30, 36, 48, 54, 60 and 72 hours post-Dose 1 on Day 1	Participants were asked to complete one preacher curl, using the arm that was exercised earlier to stimulate 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.
Number of Doses of Rescue Medication	Baseline up to Day 4	Acetaminophen 500 milligram (mg) every 6 hours as needed was used as rescue analgesia/therapy during the course of the study.
Time to First Use of Rescue Medication	Baseline up to Day 4	Time to first us of rescue medication was defined as time (in hours) from a dose of study medication to the first use of recue medication and was censored at the time of the next dose of study medication, or at 12 hours after the final application of the study medication. Acetaminophen 500 milligram (mg) every 6 hours as needed was used as rescue analgesia/therapy during the course of the study.
Muscle Soreness Relief at Each Time Point	1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 24, 30, 36, 48, 54, 60 and 72 hours post-Dose 1 on Day 1	Participants were asked: "Which phrase best describes the relief of muscle soreness which you are experiencing?" Participant's response was recorded using a five-point scale: 0 = None, 1 = A little, 2 = Some, 3 = A lot and 4 = Complete, higher scores indicated better response/more relief.
Percentage of Participants Taking Rescue Medication	Baseline up to Day 4	Acetaminophen 500 milligram (mg) every 6 hours as needed was used as rescue analgesia/therapy during the course of the study.
Participant's Global Assessment of Medication at Day 4	Day 4	Participants were asked the following question: "How would you rate this medication as a pain reliever?" Participant's response was recorded using a five point scale: 1 = Very Poor, 2 = Poor, 3 = Fair, 4 = Good, 5 = Very Good, where higher score indicated better response.
