Four Weeks of Nordic Hamstring Exercises Impact the Strength and Balance of the Hamstring Muscle Group
An observational study of Hamstring Injury, run by Gdansk University of Physical Education and Sport at 1 site in Poland.
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.

About this study
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.
Read the detailed 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Nordic hamstring exerciseOther
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.
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: Other: Nordic hamstring exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
Measured: 15 min
Secondary outcomes (1)
Biodex System
The maximum muscle strength of the hamstring group will be assessed for both legs
Measured: 20 min

Questions about this trial
What is this clinical trial studying?
An observational study of Hamstring Injury, run by Gdansk University of Physical Education and Sport at 1 site in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Biodex Balance System (time frame: 15 min). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2024.
