Mean inspired volume for the MIN, MOD, and MAX loads. For MIN, volume was higher at lift-off and +50% compared to placement, as well as at +25% compared to −25%, −50%, −75%, and placement. For MOD, volume was higher at −25% compared to −75%, as well as at lift-off, +25% and +50% compared to all pre-lift and placement. For MAX, volume was higher at lift-off and +25% compared to pre-lift, +50%, +75% and placement, as well as at −25%, +50%, and +75% compared to −50% and −75%. In addition, at −75%, lift-off, +25%, +75%, and placement volume was higher when comparing MAX with MIN. Further, at lift-off and +75% volume was higher when comparing MAX with MOD. All differences (p<0.05)
