Acute Study on Muscle Soreness, Damage, and Performance

A Randomized, Double-blind, Placebo Controlled, Single-center Study to Determine the Effects of Pre-workout and Recovery Formulations on Soreness, Performance, Tolerance and Safety Outcomes in Healthy Adults Undergoing Training Program

The acute study will evaluate pre- and post-exercise ingestion of a multi-ingredient supplement in a randomized, double-blind, placebo-controlled, crossover design. Participants will complete one enrollment visit, in which they will sign a consent form and complete a health history questionnaire. Participants will complete two interventions, with three visits each (6 visits total), in which a treatment beverage (pre/post supplement, or non-caloric placebo) will be consumed within 30 minutes prior to exercise and within 15 minutes post-exercise, in random order. Total time from enrollment to completion will be at least 14 days. Testing visits will be separated by a minimum of 7 days of rest to allow for recovery and washout, based on a half-life of ≤8 hours for all ingredients present in the supplement.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Performance	Change from baseline on performance by measuring countermovement vertical jump height using a jump mat and associated velocity using a linear transducer.	baseline, 24 hours, 48 hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Muscle soreness	Change from baseline on muscle soreness using visual analog scale (a horizontal 100 mm line where zero will represent no soreness and one-hundred will represent maximum amount of soreness. Participants will be asked to place a single vertical that represents their current soreness. The scale will be measured with a calibrated ruler with the higher numbers representing more soreness.)	baseline, 24 hours, 48 hours
Creatine Kinase	Change from baseline on muscle damage by measuring creatine kinase	baseline, 24 hours, 48 hours
Isoprostanes	Change from baseline on muscle damage by measuring isoprostanes	baseline, 24 hours, 48 hours
