Mogrosides for Delayed-Onset Muscle Soreness

This study will examine whether taking mogrosides, natural compounds found in monk fruit, affects delayed-onset muscle soreness (DOMS) and related markers of muscle damage, inflammation, oxidative stress, and muscle function after strenuous exercise. The study will also explore whether changes in the body's antioxidant capacity are related to changes in DOMS-related measures. The study plans to enroll 16 healthy young male students. Participants will be randomly assigned to a control group (n=8) or an experimental group (n=8). The control group will receive a placebo, and the experimental group will receive mogrosides. Participants will take their assigned product by mouth for 27 days, perform a standardized frog-jump training session, and then continue taking the assigned product for 3 more days. Researchers will measure subjective muscle soreness using a visual analog scale (VAS) at baseline before supplementation, before exercise, immediately after exercise, and 24, 48, and 72 hours after exercise. At these same time points, they will also measure serum creatine kinase (CK) and creatine kinase isoenzyme MM (CK-MM) activity, total antioxidant capacity (T-AOC), malondialdehyde (MDA), plasma interleukin-6 (IL-6), thigh circumference at the junction of the middle and lower thirds of the thigh, maximal isometric strength for lifting the thigh, and active range of motion (AROM) of the knee. The study will assess the effects of mogroside supplementation on DOMS severity and on changes in muscle damage, inflammation, oxidative stress, and muscle function. It will also explore whether improved antioxidant capacity is related to changes in DOMS-related indicators. This study is not yet recruiting participants.
