The Impact of Whole-Body Vibration and Relaxation Techniques on Adolescent Athlete Girls With Triad Syndrome" (WBV for triad)

实验性的：Whole body vibration

group A contains 25 Participants in this group will receive Whole-Body Vibration (WBV) combined with Relaxation training three times per week for 8 weeks. Each session will include static and dynamic exercises performed on a vibration platform under physiotherapist supervision. The intervention aims to improve bone mineral density and hormonal regulation in adolescent athlete girls with Female Athlete Triad Syndrome.

Participants in study group will receive a combination of Whole-Body Vibration (WBV) training and relaxation techniques during the same intervention period.

Each session will include approximately 15-20 minutes of WBV exercises performed on a vibration platform under physiotherapist supervision, followed by 20-30 minutes of guided relaxation training involving deep breathing, progressive muscle relaxation, and mindfulness-based relaxation.

The sessions will be conducted three times per week for 8 weeks. In control group participant will receive relaxation techniques the program will include a combination of guided breathing exercises, progressive muscle relaxation, and mindfulness-based relaxation.Each session will last about 20-30 minutes, conducted three times per week for 8 weeks, supervised by a physiotherapist or psychologist trained in relaxation therapy.

其他：relaxation training

for both groups (A&B) will receive relaxation Techniques Training

The program may include:

1. Diaphragmatic (Deep) Breathing Focus on slow, controlled breathing from the diaphragm Typically: 4-6 breaths per minute
2. Progressive Muscle Relaxation (PMR) Tensing and relaxing different muscle groups Increases body awareness and reduces physical tension
3. Autogenic Training Uses visualizations and self-suggestions to induce relaxation (e.g., "My arms feel heavy and warm") Enhances self-regulation and calmness
4. Mindfulness Meditation Focuses on present-moment awareness Helps reduce intrusive thoughts, improve attention and emotional regulation

hormonal regularity

hormonal regularity via Estrogen serum analysis It involves measuring the levels of estrogens (primarily estradiol) in the blood to evaluate reproductive health, menstrual cycle function, fertility, menopause status, or hormonal disorders.

bone mineral density

bone mineral density via DEXA. that used to diagnose osteoporosis, assess fracture risk, and monitor changes in bone over time. The gold standard for assessing BMD is the DEXA scan (also known as DXA, or Dual-Energy X-ray Absorptiometry).

psychological well-being

psychological well-being via Hamilton Anxiety Rating Scale (HAM-A) (Hamilton, 1959) This scale measures the anxiety symptoms severity. It has 14 items and series of symptoms define every item. 5 point Likert scale is used to rate each item i.e. (1) never, (2) rarely, (3) sometimes, (4) very often, (5) always. Mild anxiety is indicated by lowest score and the highest scores indicate severe anxiety.
