Relating Human Static Work of Standing and the Coefficient of Friction between the Shoe and Floor Using a Link-System Model

Maintaining a standing posture is fatiguing and additional muscle effort is required if the floor-shoe interface allows easy slippage. Requiring workers to stand on “slick” surfaces is known to be dangerous. A link-system model of the human body is used to calculate the moments at the hip joints required to maintain a standing position. The values of the moments are functions of the coefficient of friction at the floor-shoe interface.
