研究概览
简要总结
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).

结局指标
主要结局
Change in perceived muscle soreness
时间窗: From baseline to post 5-week intervention
Visual Analog Scale for perceived muscle soreness Each number on the scale will be designated with a descriptive word that corresponds to the soreness level they are experiencing. The scale will be laid out in order of increasing muscle soreness with "1" representing no pain.
Change in pressure pain threshold (PPT)
时间窗: From baseline to post 5-week intervention
Calf pressure pain threshold (PPT) will be assessed by placing marks on the medial condyle of the femur and the posterior of the medial malleolus. The researcher will place the algometer on the muscle belly exactly halfway between the two marks. Volunteers will be instructed to specify when the first onset of pain occurs as the researcher gradually applies pressure. Quadricep measurements will involve the participant lying in the supine position where marks will be made on the anterior inferior iliac spine and the top of the patella so the researchers can once again find a point exactly halfway between these two locations to apply the algometer. Participants will be instructed to verbally indicate to the researcher when the onset of pain occurs as pressure is applied.
Change in countermovement jump assessment (CMJ) performance recovery
时间窗: From baseline to post 5-week intervention
The researchers will demonstrate and instruct volunteers to "Stand upright with their hands above their head. When you are ready, bend your knees and stick your hips back while keeping your hands to your hips. Jump as high as possible and land softly." Participants will perform three CMJs separated by 60 seconds. Jump height will be recorded in cm and the highest value will be recorded.
