Question

Which of the following best describes step length?

a. distance between heel strike of one leg and its subsequent heel strike
b. time the heel of one extremity touches the floor until same foot touches floor again
c. distance between heel strike of one limb and heel strike of another
d. time it takes from heel strike of one limb to heel strike of the other

Answer 1

Step length refers to the distance between the heel strike of one foot and the heel strike of the opposite foot during walking or running. It is a measure of the space covered with one step.

Step-by-step explanation:

The student has asked about 'step length,' which is a critical element in gait analysis and biomechanics. Step length is defined as the distance between the heel strike of one limb and the heel strike of the opposite limb. This is distinct from step duration or cycle, which would involve timing elements. Therefore, the correct answer to the question is 'c. distance between heel strike of one limb and heel strike of another'.
