Document Summary
1-50% = right stance phase, left swing phase. 50-100% = right swing phase, left stance phase. Stance foot in contact with ground. Swing when foot not in contact with ground. Double support both legs on ground. Single support one foot on ground. Walking base distance between feet (width) Step length distance from one point on one foot to same spot on other foot. Stride length distance from initial contact of one foot to initial contact of same foot (cycle) Stride period time of initial contact of one foot to contact of same foot. Gait speed = stride length x stride frequency. Athletes may rely on either step frequency or step length. Use each of the 3 planes for the different planes. When doing the calculations use the equation which only has 1 variable missing. Human acceleration is rarely constant therefore not accurate to use in this equation. Acceleration due to gravity is constant for all objects.
