Can hamstring injuries be prevented?
There is no foolproof way to completely avoid hamstring injuries. However, the risks can be minimized by paying attention to the principles of muscle strength and flexibility. Individual flexibility should be maximized by a regular stretching program as well as a period of warm-up and stretching before the intended athletic activity. Optimal individual hamstring strength is at least half of the strength of the quadriceps muscle (muscle of the front of the thigh). Also, there should be minimal imbalance in strength between right and left legs (the injured hamstrings should be about 90% as strong as the uninjured hamstrings). If necessary, a weight-training program should be instituted to optimally achieve these goals. A well-balanced diet and appropriate fluid intake are essential to avoid electrolyte imbalance and dehydration. Dehydration can lead to muscle cramping, thereby increasing the chance of muscle injury. Excessive body weight increases the risk of muscle injuries in the lower
