Risk factors
By Mayo Clinic staffFactors contributing to sprains and strains include:
- Poor conditioning. Lack of conditioning can leave your muscles weak and more likely to sustain injury.
- Fatigue. Tired muscles are less likely to provide good support for your joints. When you're tired, you're also more likely to succumb to forces that could stress a joint or overextend a muscle.
- Improper warm-up. Properly warming up before vigorous physical activity loosens your muscles and increases joint range of motion, making the muscles less tight and less prone to trauma and tears.
