Background: This study aimed to compare the effects of applying a vibrating foam roller before resistance exercise versus after resistance exercise on changes in serum muscle damage markers, muscle stiffness, and range of motion. This study also aimed to provide foundational data for optimizing the timing of vibrating foam roller application to enhance recovery after resistance exercise in practical settings. Methods: Twelve healthy adult males were recruited as participants. Each participant was subjected to three interventions in a random order with a washout period of at least 5 days: vibration foam rolling before resistance exercise, vibration foam rolling after resistance exercise, and resistance exercise without vibration foam rolling. Blood creatine kinase, knee flexion range of motion, and muscle stiffness were measured before, immediately after, 24 hours after, and 48 hours after exercise and foam rolling protocols. Results: Creatine kinase levels in vibration foam rolling after resistance exercise were significantly lower than those in vibration foam rolling before resistance exercise at 24 and 48 hours post-exercise. Muscle stiffness was significantly lower immediately and 24 hours post-exercise in vibration foam rolling after resistance exercise than in vibration foam rolling before resistance exercise and resistance exercise without vibration foam rolling. Knee flexion range of motion was significantly lower in resistance exercise without vibration foam rolling than in vibration foam rolling after resistance exercise at 24 and 48 hours post-exercise. Conclusions The application of vibration foam rolling after resistance exercise was more effective than that before exercise in decreasing muscle damage markers, reducing muscle stiffness, and improving the range of motion.
