Whole body vibration as an adjunct to static stretching

Area of Science:

• Sports Medicine
• Biomechanics
• Exercise Physiology

Background:

• Flexibility is crucial for athletic performance and injury prevention.
• Static stretching is a common method to improve flexibility.
• The efficacy of combining whole-body vibration (WBV) with stretching requires further investigation.

Purpose of the Study:

• To compare the effectiveness of static stretching alone versus static stretching combined with WBV for hamstring flexibility.
• To assess the retention of flexibility gains after a 3-week follow-up period.

Main Methods:

• A randomized controlled trial involving 34 recreationally active college students.
• Three groups: control, static stretching (SS), and vibration + static stretching (V).
• Intervention lasted 4 weeks (5 days/week), followed by a 3-week retention period. Hamstring flexibility measured via passive knee extension.

Main Results:

• Significant differences observed in treatment groups, time, gender, and treatment*time interaction.
• The vibration + static stretch group showed a 22% increase in flexibility, compared to 14% for the static stretch group.
• After 3 weeks, the static stretch group returned to baseline, while the vibration group maintained significantly improved flexibility.

Conclusions:

• Concurrent stretching with WBV is an effective adjunct to static stretching for enhancing hamstring flexibility.
• WBV may improve the retention of flexibility gains compared to static stretching alone.
• This combined approach offers potential benefits for athletes and active individuals seeking lasting flexibility improvements.
