Brief Summary

The aim of the study is to assess the impact of 4 weeks of eccentric Nordic Hamstring Exercise training on changes in the hamstring muscle group, as well as to analyze parameters such as maximum muscle strength of the knee flexors, RFD (rate of force development) and static balance, dynamics for the dominant leg.

Conditions

Hamstring Injury

Outcome Measures

Primary Outcomes (1)

• Biodex Balance System

  The medial-lateral stability index (MLSI), anteroposterior stability index (APSI) and general static and dynamic stability index will be assessed for both limbs and the dominant leg

  15 min

Secondary Outcomes (1)

• Biodex System

  20 min

Study Arms (1)

Nordic Hamstring Exercise

The subjects will be randomly divided into two research groups. The first research group will undergo a 4-week Nordic Hamstring Exercise training, the second research group will be a control group performing traditional exercises.

Other: Nordic hamstring exercise

Interventions

Nordic hamstring exercise OTHER

Nordic Hamstring Exercise involves a controlled descent of the upright torso from a vertical kneeling position forward towards the ground (parallel to the ground) and returning to the starting position. The ankle joints are stabilized by the other person's grip during a series of exercises.
