Energetic Cost and Preferred Speed of Walking in Obese vs. Normal Weight Women

There was a hypothese; that walking is more expensive for obese women. That for they prefer lower walking speeds that minimize the gross energy cost per distance. Twenty adult women, 10 obese and 10 normal weight.  Subjects walked at six speed 0.50, 0.75, 1.0, 1.25, 1.5, and 1.75 m/s. Five minutes trials and five minutes rest period between trials. Walking was 11 % more expensive for the obese subjects. the obese subjects walked the same speed than normal subjects walked; 1.40 - 1.47 m/s in other words 5.0 - 5.3 km/h.

1.0 - 1.12 - 1.25 - 1.6
0.11 x 100 % = 11 %

                                   1                             1

                              1        1                        1.1 x 1 = 1.1

                         1        2       1                    1.1 x 1.11 = 1.21

                     1       3         3      1               1.1 x 1.21 = 1.331

The maximum test speed was 1.75 m/sec = 6.3 km/hour. Half of the test has been rest time and that for maximum walking speed was 3.15 km/h. This is about the natural walking speed to human, who has 98 cm legs. Of this there is on these pages a calculated example which determined 3.3 km/h.
