Comparison of Two Techniques for Maintaining Range of Motion

October 11, 2022 updated by: Seyyada Tahniat Ali, Bahria University

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.

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 , .

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: strength training group
the group will receive strength training
Other: strength training
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.
Experimental: whole body vibration stretching group
the group will receive stretching on whole-body vibration
Other: stretching on whole body vibration
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.
