Is there a relationship between a person's height and the length of his or her stride?Featured science projectScience project video

Abstract

This experiment was performed to investigate how a personís height will affect the distance of his or her stride. Comparisons were made between boys and girls and between different age groups.

Hypothesis

The ratio of the height of a person to his or her stride does not vary much between genders and over different age groups.

Scientific Terms

Step length, stride distance

Background

Walking and stride distance

Walking is the most basic form of transportation for human beings. An average person should be able to walk at a pace of about 3 miles per hour. Walking can also be done for leisure, or as a form of exercise .There are also a lot of health benefits to be gleaned from walking. Persons who walk frequently are known to be less likely to fall victim to serious illnesses such as diabetes, stroke and heart disease.

The distance that a person covers, depends both on the number of steps taken and his or her step length or stride distance. Step length is measured as the distance from the heel of the back foot, to the heel of the foot ahead where it touches the floor. The stride distance is the distance between the heel of the first foot and the heel of the same foot where it touches the floor again. The stride distance is therefore twice the measurement of the step length.

Proper walking techniques make us fitter, healthier and help prevent injuries. "Over-striding" happens when we intentionally increase the distance between our steps by stretching our front feet further than what we would normally do. This does not help us walk any faster, and may even resulting in hurting your heels.
