About this study
Official title: Comparison of Static Stretching on Whole Body Vibration and Strength Training for Improving and Maintaining Hamstring Range of Motion
Flexibility is a measurable physical capacity considered a key component of physical fitness. Poor flexibility is usually attributed to excessive tension exerted by the antagonist muscles of the movement and supported by weak scientific evidence, static stretching is considered as the most effective intervention in the promotion of muscle extensibility, in attempting to improve mobility.
Read the detailed description
Flexibility is a measurable physical capacity considered as a key component of physical fitness thereby contributing to the health and performance of joints and the musculoskeletal system. In recent years, there has been increasing evidence that muscle weakness is a major factor behind reduced mobility. Consequently, training muscle contractility is likely to improve mobility . Regardless of terminology and of the quality of supporting evidence, stretching emerges as an intervention that elongates the tissues in attempting to improve mobility . Shortening lengthens the tissue on two out of three axes, while stretching only lengthens the tissue on one axis out of three . All training, including movement, is, by definition, training of shortening and stretching cycles (SSCs). Ergo, resistance training is also, inherently, one way to elongate . Strength training is an active, voluntary, dynamic form of stretching. Indeed, strength training is dynamic stretching. Often, strength training is performed against external resistances, but this is not mandatory. Moreover, strength training has been shown to improve mobility in sedentary adults , .

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
stretching on whole body vibrationOther
SSubjects will be refrained from maximum-effort or new routines for exercise the day before each treatment.Static stretching of hamstring on whole body vibration will include Pre- and post-test active and passive ROM for the both legs, with subjects first undergoing a 5-minute warm-up on a stationary bicycle. The traditional static stretch consisted of a supine active knee extension on whole body vibration (WBV) at 30 Hz at the "high" amplitude setting will be performed. The stretch will be held at the point of the onset of discomfort 3 times each for 30 seconds, with a 20-second rest period between each stretch. Participants will stretch for 4 days per week for 4 weeks. Active hamstring ROM will be measured via active knee extension using a goniometer with the leg in 90° of hip flexion, with the opposite leg extended. Passive ROM will be measured via clinician-assist ted knee extension with the leg in 90° of hip flexion.
strength trainingOther
In second group, strength training will be done for 4 days per week for 4 days. Subjects will have 5 minutes warm up. In 1st week, the protocol will be Nordic hamstring curl (NHC) with bend (3 sets of 8 reps), Prone hamstrings curl (4 sets of 12 reps/leg), Physio-ball leg curl (3 sets of 8 reps), Glute bridge (2 sets of 50 s/leg). In 2nd to 4th week, the protocol will be NHC with bend (3 sets of 12 reps) Prone hamstrings curl (3 sets of 14 reps/leg) Physio-ball leg curl (3 sets of 10 reps) Glute bridge (2 sets of 50 s/leg). There will be 30 seconds rest between each set and 1 minute rest between each exercise . Pre and post AROM and PROM will be measured. Active hamstring ROM will be measured via active knee extension using a goniometer with the leg in 90° of hip flexion, with the opposite leg extended. Passive ROM will be measured via clinician-assisted knee extension with the leg in 90° of hip flexion.

What is being measured
The primary outcome is the main question the study is designed to answer.
change in hamstring range of motion
pre and post-change in hamstring range of motion will be assessed using a universal goniometer
Measured: measurements will be recoded at baseline and end of 4th week
maintenance of change in hamstring range of motion
hamstring range of motion will be reassessed after 15 days using a universal goniometer
Measured: measurements will be recorded after 15 days of protocol termination

Questions about this trial
What is this clinical trial studying?
A study testing stretching on whole body vibration and strength training in people with Healthy, run by Bahria University at 1 site in Pakistan.
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 8 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 13 Oct 2022. 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 Pakistan. 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?
change in hamstring range of motion (time frame: measurements will be recoded at baseline and end of 4th week). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05154110, which also lists 6 linked publications.
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 13 Oct 2022.
