A Heavy Walk
This example refers to individuals who are themselves heavier than average,
not to individuals carrying additional weight in the form of objects. Naturally
some of the effects may be similar in both cases.
FIG 5.41
Side and front views of the
walk cycle of a heavy figure.
As a result of excessive weight, an individual may begin to experience
difficulties in mobility, which may increase with the increase in weight. The
increase in body mass may also mean an increase in inertia, resulting in
slower acceleration rates and lower top speeds during locomotion. Energy
expenditure will also be greater.
As a result of the increase in body size, the position of the arms may be forced
slightly away from the vertical and away from the body.
If the additional weight is located at the front of the figure, around the waist
area, there may be a slight shift in the center of gravity, resulting in the
individual beginning to lean slightly backward in an effort to counter the
weight and maintain balance. Such a figure standing and walking may then
be seen to have a backward lean, which, over time, may develop a slight curve
in the spine. Such a posture is clearly evident in women during pregnancy,
particularly during the later stages, when considerable additional weight is
located at the front of the body.
