Top football clubs such as Leicester City use the NordBord to help their players avoid hamstring injuries
HAMSTRINGS are as large as they can be limiting. Running the length of the thigh from the back of the knee to the hip, the stringy muscles and tendons are engaged in bending the knee and straightening the hip, relied upon heavily for any movement involving power and speed.
With each running stride or jump, the strain on the hamstring is considerable and, if insufficiently prepared, they will buckle beneath it, a pull or tear being the painful consequence.
