CONTEXT: Muscle fatigue and acute muscle soreness occur after exercise. Application of a local vibration intervention may reduce the consequences of fatigue and soreness. OBJECTIVE: To examine the effects of a local vibration intervention after a bout of exercise on balance, power, and self-reported pain. DESIGN: Single-blind crossover study. SETTING: Laboratory. PARTICIPANTS: 19 healthy, moderately active subjects. INTERVENTIONS: After a 30-min bout of full-body exercise, subjects received either an active or a sham vibration intervention. The active vibration intervention was performed bilaterally over the muscle bellies of the triceps surae, quadriceps, hamstrings, and gluteals. At least 1 wk later, subjects repeated the bout, receiving the other vibration intervention. MAIN OUTCOME MEASURES: Static balance, dynamic balance, power, and self-reported pain were measured at baseline, after the vibration intervention, and 24 h postexercise. RESULTS: After the bout of exercise, subjects had reduced static and dynamic balance and increased self-reported pain regardless of vibration intervention. There were no differences between outcome measures between the active and sham vibration conditions. CONCLUSIONS: The local vibration intervention did not affect balance, power, or self-reported pain.
