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

May 8, 2026 updated by: shaimaa Mohamed hamed, MTI University

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.

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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

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.

Other: 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
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
hormonal regularity
Time Frame: 2 months
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.
2 months
bone mineral density
Time Frame: 2 months
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).
2 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
psychological well-being
Time Frame: 2 months
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.
