Comparison between dynamic oscillatory stretch technique and static stretching in reduced hamstring flexibility in...

Area of Science:

• Sports Medicine
• Rehabilitation Science
• Physical Therapy

Background:

• Asymptomatic hamstring tightness is common in healthy individuals.
• Improving hamstring extensibility is crucial for preventing injuries and enhancing athletic performance.
• Both dynamic oscillatory and static stretching are used to address hamstring tightness, but their comparative efficacy is not fully understood.

Purpose of the Study:

• To compare the effectiveness of dynamic oscillatory stretch versus static stretching.
• To evaluate improvements in hamstring extensibility and pain reduction in healthy individuals with hamstring tightness.

Main Methods:

• A single-blind randomized controlled trial was conducted with 83 healthy young adults.
• Participants were divided into two groups: dynamic oscillatory stretch and static stretching.
• Hamstring length and pain tolerance during passive straight leg raise were measured at baseline, immediately post-intervention, and 1 hour post-intervention.

Main Results:

• The dynamic oscillatory stretch group showed significantly greater improvements in hamstring flexibility compared to the static stretching group.
• The dynamic oscillatory stretch group also reported significantly less perceived pain post-intervention.
• These benefits were observed at both immediate and 1-hour follow-up assessments.

Conclusions:

• Dynamic oscillatory stretching is more effective than static stretching for improving hamstring flexibility.
• Dynamic oscillatory stretching also offers superior pain reduction compared to static stretching.
• This technique presents a more advantageous approach for managing hamstring tightness.
