Table 1.
Characteristics of the study group (mean ± SD).
Fig 1.
Illustration of pace conducted test performance.
The lower graph describes the required speed and the upper curves the measured VO2 and MAD values during the whole test. The unit mg denotes milligravity.
Fig 2.
Preferred gait types in different speeds.
The preferred gait of the fully completed stages is shown for each speed.
Fig 3.
Oxygen cost and consumption in different speeds.
The oxygen cost of the locomotion (black circles) describes the economy and the oxygen consumption (open circles) the intensity of the movement.
Fig 4.
Sensor placement and MAD in different speeds.
The measured mean MAD value with the three sensor positions is shown only for speeds performed by all 29 participants. The whiskers denote the 95% confidence intervals of the mean value. The unit mg denotes milligravity.
Table 2.
Mean and range of within-individual correlations between MAD and VO2, and MAD and speed.
Fig 5.
Relationship between VO2 and MAD.
Stages containing only walking have open circle and other stages black circle. The dotted lines denote 3 MET and 6 MET thresholds and the unit mg denotes milligravity.
Fig 6.
The dotted lines represent the optimal MAD cut-points for 3 and 6 MET limits. The MAD values are shown up to 600 mg. The unit mg denotes milligravity.

ROC curves and AUC for cut-points.
ROC curve and AUC (mean and 95% confidence interval (95% CI)) for 3.0 MET limit (left) and for 6.0 MET limit (right).
