Flexibility is an integral component in any conditioning program. Flexibility has been defined as the ability of a muscle to lengthen and allow one or more joints in a kinetic chain to move through a range of motion. The lack of flexibility of the hamstring muscle group has been associated with a higher risk of non-contact muscle injury, and for se...

Background: Muscle injury is the most common type of injury in football. Previous research has focused on traditional risk factors (eg, age, injury history, muscle imbalance/inflexibility) contributing to muscle re-injury. The effect of poor cooperation between the coaching and medical teams on the risk of re-injury remains unexplored in the sport...
