Summary

The goal of this clinical trial is to assess the effect of whole body vibration (WBV) on postural stability, flexibility of the lumbar-pelvic-hip complex and lower leg muscles, and jumping ability in basketball players aged 9-15 years. The main questions it aims to answer are: Does WBV affect the level of postural stability in basketball players aged 9-15 years? Does WBV affect the level of postural stability in basketball players aged 9-15 years? Does WBV affect the flexibility of the iliopsoas, rectus femoris, posterior group of hamstrings, soleus and gastrocnemius in basketball players aged 9-15 years? Does WBV affect the jump height, relative peak power, contraction time in basketball players aged 9-15 years? Participants will take part in 6 vibration sessions at 20Hz over 6 weeks. Vibration will be performed on the Galileo Med35 platform (3x3 min).

Conditions

• Generalized Joint Hypermobility

Interventions

Type	Name	Description
OTHER	Whole Body Vibration	Whole body vibration consists of 3-minute vibrations with a 30-second break. Participants were asked to step onto the platform barefoot and position their feet "3" from the center of the platform, with feet pointing forward, knees slightly bent, and upper limbs along the body. The training was divided into two parts: week 1 with a frequency of 20 Hz, and a constant amplitude of 3 mm.
