Cardiovascular Responses in Adolescent Idiopathic Scoliosis Girls

The aims of this pilot study are to determine the metabolic demand and exercise intensity level of E-Fit exercise intervention by evaluating the cardiovascular responses in AIS girls and whether the cardiovascular responses for AIS girls performing E-Fit will behave in the same way as compared to healthy controls. We hypothesise that 1) the metabolic demand and exercise intensity of E-Fit exercise intervention is equivalent to moderate-to-vigorous level; and 2) AIS girls have different cardiovascular responses as compared to healthy controls

About this study

AIS girls and age- and gender-matched healthy controls will perform the E-Fit exercise intervention for two trials and gas exchange parameters including oxygen consumption (VO2) and carbon dioxide production (VCO2) will be taken continuously during the exercise. Comparison of VO2 and VCO2 between AIS and healthy controls when performing E-Fit exercise will be made.

Treatment and study plan

Exercise

Behavioral

Two trials of 7-min High Intensity Interval Training (HIIT) with 12 different exercises. Each exercise lasts for 30 seconds continuously with 10 seconds rest interval.

Primary outcomes

  1. Respiratory gas measurement

    Time frame: Day 1

    Breath-by-breath measurement of cardiorespiratory and gas exchange parameters to analyse oxygen consumption (VO2 in ml/min) and carbon dioxide production (VCO2 in ml/min).

  2. Blood Pressure

    Time frame: Day 1

    Blood pressure (mmHg) will be measured using an electronic sphygmomanometer.

  3. Heart rate

    Time frame: Day 1

    Heart rate (bpm) will be measured using a fingertip oximeter.

  4. Oximetry

    Time frame: Day 1

    Peripheral capillary oxygen saturation (%) will be measured using a fingertip oximeter.

Secondary outcomes

  1. Maturity assessment

    Time frame: Day 1

    Sexual maturity using Tanner Scale and onset of menarche will be measured.

  2. Modified Baecke Questionnaire

    Time frame: Day 1

    Habitual physical activity level will be assessed by self-administered questionnaire.

  3. Physical Activity Rating Questionnaire for Children and Youth (PARCY)

    Time frame: Day 1

    Physical activity level and intensity will be assessed by self-administered questionnaire.

  4. Body height

    Time frame: Day 1

    Body height (cm) will be measured with standard stadiometry techniques.

  5. Sitting height

    Time frame: Day 1

    Sitting height (cm) will be measured with standard stadiometry techniques.

  6. Arm Span

    Time frame: Day 1

    Arm span (cm) will be measured with standard stadiometry techniques.

  7. Body Composition

    Time frame: Day 1

    Percentage body fat (%), body weight (kg), lean muscle mass (kg) will be assessed using Bioelectric Impedance Analysis.
