  1. Data are means±standard deviation
  2. TBW total body water, FM fat mass, PM protein mass, MC mineral mass, BMI body mass index, VC vital capacity
  3. aRefers to the p value of an independent test (continuous variables) between male and female students
  4. bMeans higher value (in scores) indicate better performance
