What is a hamstring strain?
A mild hamstring strain may feel like a tightness or low grade aching pain in the muscle. Pain is often aggravated by walking, running, straightening the knee or bending down, however may ease off with light exercise due to increased blood flow. Reduced hamstring flexibility and strength, poor running mechanics, inappropriate training loads and fatigue are all factors that may contribute to hamstring strains. Hamstrings can also become troublesome with tight hips or weak glutes, as this increases the strain on the hamstrings.
