The acronym PICO stands for Population (in the actual review: soccer-football-rugby players), Intervention (static stretching of the hamstring muscle), Comparator (athlete with intervention programme and without intervention programme and Outcomes (range of motion as injury prevention, static stretching as injury prevention)[43].
During phase 1, an active contraction of the stretched hamstring muscles is performed voluntarily (either isometric or concentric).
These improvements were accompanied by an enhanced reflex activity of the hamstring muscles. No significant differences were found for any variable for the subjects who had trained with the semi-rigid ankle brace.
If the client complains of muscle tightness in the back of the thigh, the problem is most likely lack of flexibility in the hamstring muscles. If the patient complains of back or hip pain or nerve pain (characterized by numbness, tingling, a sharp pain or something that feels like electricity), he or she should be referred to a physician.
(1996) Biomechanical responses to repeated stretches in human hamstring muscle in vivo.
The cut-off values of the AKE and the PKE test for the detection of short hamstring muscle flexibility were calculated based on the normal distribution approach (95% of the population was accepted as normal).

This single exercise protocol, which involves a controlled lowering of the trunk to the floor from a kneeling position, increases the eccentric strength of the hamstring muscle and thereby improving its ability to tolerate high loads while placed under stress.
They concluded that the knee extension deficit observed in most patients was due to hamstring muscle spasms secondary to arthrogenic muscle inhibition.
When the specific area of tightness of hamstring muscle is located, the further treatment is limited to this target area.
