ABSTRACTThe 12-Minute Cycle Ergometer Test (12MCET), an accurate JOURNAL/jscr/04.02/00124278-199511000-00013/ENTITY_OV0312/v/2017-07-20T235155Z/r/image-pngO2max prediction test, has one significant limitation: one resistance setting for men (2.5 kp), often problematic for heavier men. This study's purpose was to develop a model that better accommodated heavier men. College-age men (n = 23) and women (n = 20) had JOURNAL/jscr/04.02/00124278-199511000-00013/ENTITY_OV0312/v/2017-07-20T235155Z/r/image-pngO2max assessed via indirect calorimetry. Two days later each performed the 12MCET pedaling as fast as possible at the following resistance settings: men > 78 kg, 3.0 kp (n = 11); men <78 kg, 2.5 kp (n = 12); and all 20 women, 2.0 kp. Multiple regression analyses revealed an accurate prediction equation (R = 0.97, SEE = 206.3 ml · min−1) with only one independent variable: total work. Cross-validation on a new sample of 10 men and 10 women revealed high external validity (r = 0.93; SEE = 180.7 ml · min−1; t-test, p > 0.1). This new model is valid, demonstrates similar accuracy with only one independent variable and better accommodates heavier men.
