HEEL STRIKE Meaning and
Definition
-
Heel strike refers to the initial contact made by the heel with the ground during the act of walking, running, or any other type of locomotion. It is the first phase of the gait cycle and occurs as the heel of the foot makes contact with the surface, leading to weight bearing on that particular limb.
In the context of human gait, heel strike signifies the moment when the heel touches the ground after the swinging leg reaches forward. This action occurs in a typical heel-to-toe walking pattern, where the heel strikes the ground first, followed by the rolling motion of the foot towards the toes.
Heel strike involves a forceful impact on the ground, as the weight of the body is transferred from the swinging leg to the weight-bearing leg. The specific timing and alignment of the heel strike can vary amongst individuals, influenced by factors such as walking speed, stride length, and individual anatomical variations.
Understanding heel strike is crucial in biomechanics and the study of gait analysis. It allows experts to investigate any potential abnormalities, deviations, or irregularities in how an individual walks or runs. Analysis of heel strike is especially important in diagnosing and treating gait disorders, identifying abnormal patterns, or determining appropriate interventions to optimize an individual's walking or running mechanics.
Etymology of HEEL STRIKE
The word "heel" can be traced back to the Old English word "hēla" or "hǣla", which meant the back part of the foot or the heel. This term evolved from the Proto-Germanic word "hailijō" and shares similar roots with other Germanic languages such as German "Ferse" and Dutch "hiel".
The word "strike" originated from the Old English verb "strīcan", meaning "to smite, hit, or slap". It has Germanic origins and is related to similar words in other Germanic languages such as German "streichen" and Dutch "strijken".
When combined, the term "heel strike" refers to the action of the heel hitting the ground during walking or running. It is commonly used in the context of gait analysis and biomechanics to describe a particular phase of movement.
