Clinical Trial Summary

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.

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 , .

Intervention

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.
• 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.
