Clinical Trial 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.

Description:

Research procedure: Nordic Hamstring Exercise training covers a period of 4 weeks, during which the volunteer exercises 3 times a week for 3 sets, each set consisting of 3 repetitions of NHE. Before starting eccentric exercises, you will warm up for 15 minutes. After each series, there will be a 2-minute passive break, during which the subject will rest. In the first week, the subject will exercise under the supervision of the instructor, in the next three weeks the subject will exercise at home after prior instruction.

Related Conditions & MeSH terms

• Hamstring Injury

Intervention

Other:
• Nordic hamstring exercise
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.
