• Moderate side effects: 3-8% of users
• Serious side effects: Less than 1% of users

Common Side Effects

These are the most frequently reported side effects of vibration training. Most are mild, temporary, and resolve quickly with proper management.

Muscle-Related Side Effects

1. Delayed Onset Muscle Soreness (DOMS)

This is the most common side effect, experienced by 20-30% of new users. It typically occurs 24-48 hours after training and is similar to soreness from any new exercise.

Characteristics:

• Mild to moderate muscle aching
• Stiffness, especially in the morning
• Tenderness to touch
• Usually affects legs and core muscles

Management:

• Start with shorter sessions and lower intensity
• Gentle stretching and light movement
• Adequate hydration and rest
• Warm baths or gentle massage
• Usually resolves within 2-3 days

2. Muscle Fatigue

Some users experience unusual fatigue after vibration training, particularly when starting or increasing intensity.

Prevention:

• Gradual progression in duration and intensity
• Adequate rest between sessions
• Proper nutrition and hydration
• Listen to your body's signals

Balance and Coordination Effects

1. Temporary Dizziness

Mild dizziness immediately after training affects about 10-15% of users, especially beginners.

Causes:
