About this study

Official title: Effect of Ballistic Stretching, Extender Exercise, and Kinesio Taping on Hamstring Viscoelasticity and Rower Athletic Performance - A Preliminary Study

The study aims to investigate acute effects of ballistic hamstring stretching, hamstring extender exercise, and kinesiotaping application on viscoelasticity of hamstrings and standing long jump performance on rowers.

Read the detailed description

The study aims to investigate acute effects of ballistic hamstring stretching, hamstring extender exercise, and kinesiotaping application on viscoelasticity of hamstrings and standing long jump performance on rowers. A total of 60 professional rowing athletes were included. Viscoelasticity of hamstrings were assessed by MyotonPRO, Tallinn, Estonia. Athletic performance was assessed by Standing Long Jump Test (SLJT). The athletes were randomly divided into Ballistic Hamstring Stretching Group (n= 20), Hamstring Extender Exercise Group (n= 20), and Kinesiotape Group (n= 20). For balistic hamstring stretching, athletes were asked to reach the floor in the BS group by leaning over in the standing posture without knee flexion. When they feel the tension in hamstring muscle groups, athletes were requested to make small rebounding motion at degrees between 3°-5° for half a minute. For hamstring extender exercise, athletes were asked to apply the exercise 12 repetitions and 3 sets. Kinesiotaping was applied on the hamstring muscle with Y shape and 25% tension force.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ballistic Hamstring StretchingProcedure or surgery

    Athletes were asked to reach the floor in the BS group by leaning over in the standing posture without knee flexion. When they feel the tension in hamstring muscle groups, athletes were requested to make small rebounding motion at degrees between 3°-5° for half a minute.

  • Hamstring Extender ExerciseProcedure or surgery

    Athletes were asked to applied 12 repetitions and 3 sets of hamstring extender exercise. Firstly athlete lies on his/her back. Then, athlete is asked to do 90 degrees of knee and hip flexion at the same time. Finally, the person is expected to perform slow repetitive knee extension to the point of maximal possible extension.

  • KinesiotapeProcedure or surgery

    Kinesio tape is applied on the hamstring muscle with a Y shape and %25 tension force.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Frequency of Muscle (F)

    The tones of muscle is described by frequency of muscle or oscillation frequency (Hz). It is examined by the MyotonPro, Tallinn, Estonia.

    Measured: Day 1

  2. Stiffness of Muscle (S)

    Stiffness of Muscle is described by reaction to contraction or forces from outside of tissue that may cause the original form to deteriorate. It is examined by the MyotonPro, Tallinn, Estonia.

    Measured: Day 1

  3. Decrement of Muscle (D)

    The elasticity of a muscle is described by a logarithmic reduction of tissue's normal amplitude. It is more related with the dissipation of mechanical energy that arises between the deformation of the tissue and its recovery. It is a biomechanical feature of tissue that is called as elasticity. It is examined by the MyotonPro, Tallinn, Estonia.

    Measured: Day 1

  4. Relaxation of Muscle (R)

    It is the time which is called as Mechanical Stress Relaxation Time (ms) between the deformation of the normal shape of the tissue and its return to its original shape. It is examined by the MyotonPro, Tallinn, Estonia.

    Measured: Day 1

  5. Creep of Muscle (C)

    It is defined as ratio of deterioration and relaxation time of tissue. In case of a continuous stress, tissue regularly stretches over time. This is called as creep. It is examined by the MyotonPro, Tallinn, Estonia.

    Measured: Day 1

  6. Athletic Performance

    Athletic Performance is assessed by Standing Long Jump Test. It is a horizontal jump test that measures anaerobic performance.

    Measured: Day 1

Questions about this trial

What is this clinical trial studying?

A study testing Ballistic Hamstring Stretching, Hamstring Extender Exercise and Kinesiotape in people with Injury; Back, Lower, Superficial and Hamstring Injury, run by Yeditepe University at 1 site in Turkey (Türkiye).

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 4 inclusion and 5 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 9 Aug 2023. 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 Turkey (Türkiye). 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?

Frequency of Muscle (F) (time frame: Day 1). The study lists 6 primary outcomes in all. 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 9 Aug 2023.
