Overview

The purpose of this study is to evaluate how probiotic supplementation (PS) influences post-exercise recovery in healthy, physically active young adults. Researchers aim to determine if the Lactobacillus casei probiotic strain reduces symptoms of delayed onset muscle soreness (DOMS) based on perceived muscle soreness, pressure pain threshold, and power output following exercise induced muscle damage (EIMD).

• good general health with no injuries or health conditions that would affect physical activity
• willing to abstain from consistent NSAID use and other probiotic supplements over the course of this study

Exclusion Criteria:

• known musculoskeletal injuries or physical limitations that could interfere with performing the designated physical activity required
• underlying conditions that could place them at an increased risk during exercise such as cardiovascular, respiratory, or metabolic diseases
