DISTRIBUTION OF CHARGE IN PIES

DISTRIBUTION OF CHARGE IN PIES

The distribution of load on the feet is a fundamental aspect of the biomechanics of the human body, crucial both for the movement and for the maintenance of a correct posture. This distribution varies according to several conditions, such as the posture (foot, walking, running), the type of footwear used, the anatomy of each person's foot and any existing orthopedic condition.

Here is an overview of how the load is typically distributed under normal conditions:

In Foot Position

• General DepartmentThe following:

• Approximately 60 per cent of the load is distributed in the heel and 40 per cent in the fore (the front of the foot).

• Pressure zonesThe following:

• Talón: Supports a large part of the weight, especially the outer part of the heel.

• Antepié: The charge is mainly distributed between the first and the fifth metatarsian (the fat finger and the small finger).

• Arches: Normally it bears less load, acting as a support and distributing the load fairly.

Walking

• Fases del PasoThe following:

• Impact of the Heel: Heel is the first point of contact and bears a significant force.

• Total foot support: The load is distributed through the foot while the entire floor touches the ground.

• Departure from the finger: The load moves to the fore and to the fingers, mainly to the big toe, just before lifting the foot of the floor.

The Runner

• Change in DistributionThe following:

• It can vary considerably depending on the race technique.

• Corridors with a "leader" or "half foot" style carry more on the forefoot.

• Corridors with a "tail" style load more at the beginning of the heel.

Factors Affecting Charging Distribution

• Type of foot (normal, flat foot, high arch).

• March Style and individual biomechanics.

Importance

The way the load is distributed on the feet is crucial to preventing injuries, ensuring a comfortable and efficient march and for sports performance. Bad distribution can lead to problems such as foot, knee, hip and back pain, as well as contributing to the development of chronic deformities or conditions. It is important to pay attention to signs of inadequate load distribution, such as persistent pain or irregular footwear wear, and to look for a specialist's assessment if problems arise. The use of appropriate footwear, custom templates and specific exercises can help improve the load distribution and overall foot health.

As we increase the height of the heel, body weight moves forward. This unequal weight distribution modifies the overall position of the body and may affect muscles and joints.

A study by the Instituto de Biomecánica de Valencia (IBV) analyzes what is the recommended heel height to ensure a balanced weight distribution between the previous and the back of the foot.

As you can see in the image, the 2 cm heel is the one that best distributes the weight. From here, as we add centimeters, there is an increase in the pressure at the front of the foot.
