Acute Study on Muscle Soreness, Damage, and Performance

Completed · Not applicable · Has a placebo group

Conditions studied: Soreness, Muscle, Performance Enhancing Product Use, Damage Muscle

In brief

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.
