Study summary

This study aims to explore the effects of Whole-Body Vibration (WBV) exercises and relaxation techniques on adolescent female athletes who are experiencing Female Athlete Triad Syndrome - a condition that may include low bone density, irregular menstrual cycles, and low energy availability.

Participants will take part in a structured program combining vibration training and relaxation sessions over several weeks. The goal is to determine whether this combination can improve bone health, menstrual regularity, physical performance, and overall well-being in young female athletes.

Read the detailed description

The Female Athlete Triad is a medical condition commonly observed in adolescent female athletes and is characterized by three interrelated components: low energy availability (with or without an eating disorder), menstrual dysfunction, and decreased bone mineral density. These factors can negatively affect growth, performance, and long-term health.

This randomized controlled study aims to investigate the combined effects of Whole-Body Vibration (WBV) training and relaxation techniques on adolescent athlete girls diagnosed with the Female Athlete Triad Syndrome.

Participants will be divided into two groups : study group will receive WBV and relaxation training and control group will receive relaxation technique only. The intervention will be conducted for 8 weeks under the supervision of a physiotherapist.

Primary outcomes will include changes in bone mineral density and hormonal regulation. Secondary outcomes will assess psychological well-being.

This study seeks to provide evidence on the potential benefits of combining WBV and relaxation techniques to support bone health, hormonal regulation, and physical and mental recovery among adolescent female athletes.

Study arms

  • Experimental
    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.

    Device: whole body vibration device · Other: relaxation training

  • Experimental
    Relaxation training

    group B contain 25 Participants will receive guided relaxation training three times per week for 8 weeks. Each session will include deep breathing exercises, progressive muscle relaxation, and mindfulness-based relaxation, supervised by a physiotherapist.

    Other: relaxation training

Interventions

  • Devicewhole body vibration device

    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.

  • Otherrelaxation 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

What researchers measure

Primary outcomes

  1. 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.

    Time frame: 2 months

  2. 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).

    Time frame: 2 months

Secondary outcomes

  1. 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.

    Time frame: 2 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 14, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
