Acute Study on Muscle Soreness, Damage, and Performance

Study Overview
=================
Brief Summary
-----------------
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 |
