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.
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
