  1. Abbreviations: SD, standard deviation; Waist, waist circumference; SSK, sum of skinfolds; SBP, systolic blood pressure; DBP, diastolic blood pressure; TC, total cholesterol; VO2max, maximal oxygen uptake. a For seven subjects (control: n = 2, phone: n = 2, Internet: n = 3) one or more skinfolds were outliers, apparently due to measurement errors. These subjects were excluded from the analyses.
