Brief 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

Outcome Measures

Primary Outcomes (3)

• Changes in Postural Stability

  Postural stability was measured as the overall stability index (OSI) on the Biodex Balance System on the stable and unstable platform with open and closed eyes.

  6 weeks before the intervention, the day before the intervention began, the day after the intervention, and 6 weeks after the intervention.

• Range of motion (ROM) of the ankle, knee, and hip joints.

  Range of motion (ROM) of the ankle, knee, and hip joints, will be measured in a resting position using an inclinometer for the iliopsoas, rectus femoris, posterior hamstring, soleus, and gastrocnemius muscles separately.

  6 weeks before the intervention, the day before the intervention began, the day after the intervention, and 6 weeks after the intervention.

• Countermovement Jump Performance

  Countermovement jump performance will be measured by using force plates, It will be assessed Jump height (JH), relative peak power (RPP), and contraction time (CT).

  6 weeks before the intervention, the day before the intervention began, the day after the intervention, and 6 weeks after the intervention.

Interventions

Whole Body Vibration OTHER

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.
